A BRIEF CODE-BASED SEISMIC DIAGNOSTIC TOOL FOR EXISTING RC BUILDINGS - Philippines
A brief seismic diagnostic tool (BSDT) that is localized and based on the National Structural Code of the Philippines (NSCP) is developed as a tool for rapid visual screening of existing reinforced concrete buildings in the Philippines. A BSDT that uses seismic code parameters from the NSCP would be easier to use for local evaluators since local civil engineers are familiar with the NSCP parameters. Vertical irregularities are also known to contribute to the vulnerability of buildings when subjected to ground motion. This study will also present push-over analysis simulations of buildings with vertical irregularities specifically (1) Vertical Geometric Irregularity, (2) Soft Story, and (3) Mass Irregularity. Vertical irregularity parameters are introduced in the simulations and these parameters are introduced to determine score modifiers for the assessment of vulnerability of buildings with vertical irregularities. The result of the study is a more refined qualitative/semi-quantitative brief seismic diagnosis tool for existing reinforced concrete buildings for the Philippines.

My T-SHIRT Memories -Part 7 (Visiting University Moments)
Part of my task as a professor is to visit universities abroad as a visiting researcher or professor or to promote networking and collaborative activities between my university and other universities. Buying souvernir shirts from the university cooperative store is one of my "things to do" whenever I visit a university.
Nagoya University. I consider Japan as my second home. For five and a half years (1988-1994), I stayed at Nagoya, Japan to pursue my graduate studies (M.Eng. and D.Eng) in civil engineering at Nagoya University, Concrete Engineering Laboratory under the mentorship of Prof. Tada-aki Tanabe. Japan is my first trip abroad and living in Japan is my first experience to live alone outside of the comfort of home. Living in Japan then is very different now. Memories of Nagoya includes doing research with Japanese Lab members (Now Prof. Hikaru Nakamura, Dr. Denzil, Dr. Farahat, Dr. Wu, Dr, Yu and more), studying with foreign students (Dr. Suparat, Dr. Jerry Velasquez, Dr. Ge Hanbin) and surviving and enjoying life with Pinoy students and friends - Daisy, Mel, Cynthia, Pilo, Bong, Gilbert, Lani, Tess, Noemi, Nonoy, Edu, Prime, William, Glen, Sally, Jummy, Biboy, Arnel, Erwin, Indette, Ruth, Renan, Gerry, Roger, Ichie, Joe (+) and more. Whenever I visit Nagoya, memories of good times always come to me: hearing mass at Nanzan University Chapel and Mikokoro Church, volleyball games at Meidai Gym, Pinoy food get-togethers at Kaikan and our apartments, biking around Nagoya (Sakae, Osu, Fujigaoka), Midnight shopping for used goods, overnight outing at Gifu and Toyohashi, the Golden Week adventure trip at Fukui, Kanazawa and Nagano, the midnight mahjong games, AFSA trips and more. My family visited Nagoya in 2013 & 2014. Thank you friends for the memories!

My T-Shirt Memories - Part 6 (DLSU CE Shirts)
It has become a tradition at the DLSU CE Department during the College of Engineering Christmas Party to wear a CE Department shirt for the department presentation. Joenel Galupino and Daniel Valerio are usually assigned to design the shirts. Maybe the shirts are the lucky charm that inspires the CE Faculty members to perform well usually in dance number during the college X'mas presentations. Ever since, the CE Department has always been judged as the winner in the inter-departmental X'mas presentations.
CE-Star. Tala, tala, tala. Ang ningning ng mga tala'y nakikita ko sa 'yong mga mata. Tala, tala, tala. Ang ningning ng 'yong mga mata'y nahanap ko sa mga tala. These were part of the lyrics of the song when the CE Faculty performed the dance rendition. I believe the expert dance and instructur of the dance number was Paolo Lucero, a former Animo Squad Cheer Leader.

My T-SHIRT Memories - Part 5 (ASEP Engagements)
This series of My T-Shirt Memories is related to ASEP or the Association of Structural Engineers of the Philippines. Read more on My T-Shirt Memories Part 1 & Part 2.
Struct-Whiz Challenge. Quiz contests are popular activities for students. The Struct-Whiz Challenge is ASEP's quiz contest to promote interest on structural engineering to the students. The team of ASEP members composed of Rannie Ison. Ariel Santos, Joseph Manalo and I conceptualized the quiz which we termed, "Struct-Whiz Challenge." The quiz is supposed to select a Structural Engineering Wizard among the contestants who will first take a written qualifying exam in the morning (to qualify, a cut-off score is specified) and then if selected, has to sit in an oral competition. The top 3 contestants are awarded. But to be a Struct-Wizard, the contestant are challenged to score at least 75% or more. In the seven editions of the quiz, no contestant has met the required minimum score to be a wizard. This shirt designed by Ariel Santos (Compliments of RI) is a souvenir of the last edition of the quiz. The lightning symbol is my idea; an inspiration from Harry Potter. When will the next "Struct-Whiz Challenge" be? Is there a wizard among the civil engineering students waiting to be judged as the 1st wizard of ASEP's Struct-Whiz Challenge?

ACEE2004 Earthquake Designs. I gave an idea to ASEP in 2004 (Engr. Rannie Ison was the president then) to organize an international conference where the advisory committee is composed of international experts and professors. The cocnept was accepted and the Asia Conference on Earthquake Engineering or ACEE in 2004 was born. The founding advisers included Dr. Naveed Anwar and Prof. Pennung of AIT, Prof. Yamasaki of U. Tokyo, Prof. Kawashima of TIT, Dr. Solidum of PHIVOLCS and more. The ACEE has been continued by ASEP with cooperating institutions serving as hosts like AIT, TIT and NCREE. The latest or 7th ACEE was hosted by AIT on November 2018. The 9th ACEE will be hosted by NCREE at Taipei, Taiwan probably in 2022. I created the ACEE2004 designs below by simply capturing existing images and added my own text. The first design shows different translation of "Earthquake" in Japanese, Filipino, Spanish and French. The second design has the message,"Earthquakes don't kill, Faulty design buildings do!" The message emphasized the need to practice seismic design of structures in earthquake countries like the Philippines.

SHAKE T-Shirt. The final T-shirt is my own design for the ASEP SHAKE Conference held on November 2019. SHAKE means Smart TecHnologies and Advanced Knowledge in Earthquake Engineering. I remember holding a brain storming at Century Plaza Hotel on the next ASEP conference with a committee led by Engr. Rannie Ison and some ASEP members, Mac Mendoza, Ariel Santos, GG Garciano and more. And in that brainstorming session, "SHAKE" was born. All speakers to the conference were invited including colleagues and friends from Japan and NZ like Dr. Hazarika, Dr. Anil, Dr. Watanabe and Dr. Orense. To commemorate this 1st SHAKE Conference, I created my own design. I hope ASEP will continue to SHAKE the professional community with ground shaking and excellent conferences just like the ACEE.

My T-SHIRT Memories - Part 4 (CES Shirts)
My T-Shirt Memories - Part 4 like Part 3 will be posted in this blog. For Part 4, I will feature the T-Shirts I received from the Civil Engineering Society (CES), the CE student organization at De La Salle University Manila. CES started in 1987 and has evolved to be a very active student organization at DLSU.
CES-01 Shirt. I think this is the first T-Shirt I received from CES in 2008. If remember correctly, the design was done by Joenel Galupino, now faculty at the CE Dept. And the CES president then was Dan Aquino. I remember advising CES in their Popsicle Bridge Building Contest for several years. Read more about CES Bridge Building. The Bridge Building Contest where bridges were constructed using popsicle sticks and glue was one of the traditional activities of CES that I supported. It is a contest of creativity and analytical thinking.

My T-SHIRT Memories - Part 3 (Civil Engineering Shirts)
I am posting My T-Shirt Memories - Part 3 in this blog since it is about civil engineering. Read Part 1 (UP Shirts) and Part 2 (Apple Moments) at http://goodlife4less.blogspot.com.
November is "Civil Engineering Month" and it is timely to post my CE related shirts.
PICE III Technical Conference T-Shirt. Let me start with my PICE shirt. This shirt is one of the token given during the Philippine Institute of Civil Engineers Region III Technical Conference held on April 13-14, 2018 at Subic Bay Peninsular Hotel, Subic Bay Freeport Zone, Zambales. I remember giving two lectures then; one on "Seismic Assessment & Retrofitting Lessons from Japan" and "Making Cities Resilient." My lectures are very relevant to the T-shirt message of "Building Tomorrow, Today." Joining me as resource speakers were DLSU Faculty, Dr, Lessandro Garciano, Dr. Alexis Fillone and Dr. Marla Redillas. Dr. Romy Estanero, retired DLSU professor and now CE PRB member was also a resource speaker. Michael David, a DLSU BSCE alumnus was the organizer of the event.

CE Changing the World. I was a resource speaker at the Academe Session of the Philippine Institute of Civil Engineers (PICE) National Convention on October 29, 2019 at the SMX Convention Center. I presented a paper on "Implementing the CE Orientation Course in the Revised BSCE Curriculum" with co-authors L. Garciano, R. Mendoza, Jr. and K. Roquel.
During the break, I visited the exhibit area where various PICE shirts were sold. Most of the civil engineers were excited buying shirts with a PICE logo. In my case, I was looking for a unique design and this design caught my eye - "CE: Changing the World: One Blueprint at a Time." Indeed, civil engineers are changing the world and contribute to building the quality of life. And that was the message on our Civil Engineering Orientation Course for Freshmen at De La Salle University.

MODULAR LEARNING OF MATRIX ANALYSIS OF STRUCTURES USING ONLINE RESOURCES
To understand, learn and apply DSM effectively, a modular approach
in learning is proposed. Each module is like a building block which is
put in place one after the other until the whole coverage of the course is
completed. This blog presents modules of online resources that can
be accessed by civil and structural engineers for learning matrix analysis of
structures.
MODULE 1A - MATRIX ALGEBRA - You need to review matrix algebra to be able to apply the direct stiffness method. The YouTube Channel on Matrix Algebra for Engineers by Prof. Jeffrey Chasnov (HKUST) has a complete set of videos. Khan Academy has also a collection of videos about matrix algebra. The most important matrix operations that you need to learn are addition, subtraction, multiplication, transposition and inversion. Go to these YouTube channels - explore, navigate and learn.
MODULE 1B - USING MS EXCEL FOR MATRIX OPERATIONS - MS Excel has commands for performing matrix operations. MS Excel is a very useful tool for the course since the application of the DSM will result to matrices of large sizes which is not practical to be solved manually. Hence, MS Excel is an ideal supportive tool for matrix operations. Using MS Excel, the derived elements of the structural stiffness matrices can be easily inputted and appropriate matrix operations can be easily performed.
MODULE 2 - STRUCTURAL ANALYSIS CONCEPTS - It is important to review basic concepts on structural analysis to understand the direct stiffness method. The YouTube channel for Dr. Structure has a collection of videos on structural analysis. One important concept that you need to understand is on Stability and Determinacy of Structures. There are more videos on basic concepts like truss analysis, beam analysis (shear and moment diagrams) and analysis of plane frames for deflections and more.
MODULE 3 - ANALYSIS OF PLANE TRUSSES - The direct stiffness method has a common algorithm that can be applied to any type of structure but the elements of the matrices depends on the type of structure being analyzed. What you need to know are the stiffness matrix for each type of structural element. Let us start with the truss element where each node has two degrees-of-freedom (DOF) - the horizontal and vertical displacements. You need to learn how to transform the DOFs and matrices from local axes (x-y) to global axes (X-Y) before you can apply the DSM to the analysis of trusses. The YouTube channel of The Efficient Civil Engineer by Dr. S. El-Gamal has video of two parts on Truss Analysis using DSM. A problem in the textbook by Hibbeler is solved. Dr. Structure has also videos on Matrix Displacement Method for Indeterminate Trusses.
MODULE 4- ANALYSIS OF BEAMS - The next element that you must understand is a beam element. Each node of a beam element has also two DOFs but these DOFs corresponds to the vertical displacement and rotation. You need to review the type of loadings applied to beams - concentrated load, uniform load, couple, etc - since these loadings have to be converted into equivalent nodal forces so that the DSM can be implemented. The YouTube channel of DCBA Online has a collection of videos on the direct stiffness method. Dr. Structure has also videos on Matrix Displacement Method for Indeterminate Beams. Explore navigate and learn.
MODULE 5- ANALYSIS OF PLANE FRAMES - For a plane frame, each node has three DOFs which consist of the horizontal displacement, vertical displacement and rotation. The stiffness matrix of a plane frame element is actually a combination of a truss and beam element. Watch and learn from the videos from DCBA Online and Dr. Structure.
MODULE 6- DSM APPLICATIONS ON PLANE FRAMES
Dr. Structure has two interesting videos on application of the direct stiffness method on two types of framed structures.
(a) Analysis of a Tea House Frame
(b) Frame Analysis under Wind Load (Airplane Hangar)
MODULE 7- MASTAN2
Now that you have learned the use of DSM to various types of structures and applied the procedure using MS Excel, you can verify your results using a structural analysis software. You can use MASTAN2 - a free software!
MASTAN2 is an interactive structural analysis program that provides preprocessing, analysis, and post processing capabilities that can be adopted in the course. MASTAN2's linear and nonlinear analysis routines are based on the theoretical and numerical formulations presented in the textbook Matrix Structural Analysis, 2nd Edition, by McGuire, Gallagher, and Ziemian.

ENGAGING STUDENTS IN AN ONLINE CLASSROOM USING CANVAS
Online Teaching and Learning via Learning Management Systems (LMS) has become the new normal in course delivery due to the COVID-19 pandemic. Hence, faculty members must learn new skills using LMS and adapt to an online classroom to successfully deliver their courses and effectively assess students’ performance and achievement of learning outcomes. Canvas is one Learning Management System that has been used in many universities including De La Salle University. Canvas has several tools that the teacher and the students can use so that the course learning outcomes can be achieved. This paper and video presents how Canvas tools are used by the author using the Community of Inquiry (CoI) framework in engaging with the students in online teaching and how students can be engaged in online learning and assessment.

Some Engagement Strategies on Remote Teaching & Learning Using Canvas & Digital Tools
- Consider adding “low point incentives” (perhaps 1 point or 1 percent per activity) as an extrinsic motivator
- Instructors can set “Canvas requirements” to require students to accomplish the activity before advancing into the next module or before they can open an Assignment, File or a Quiz.
- Consider attaching eligibility for “grade bumps,” such as rounding or adding a value to the general average to get a higher final grade if they accomplish all or a majority of the activities. Example: A general average of 59.0 has final grade of 0.0, but will be bumped to 60.0 and the student will get a final grade of 1.0.
