Shapes play a major role in the behavior of structures. Observed that because of the stable upright triangular shape, the Pyramids of Egypt and the Eiffel Tower have remained structural wonders. In earthquake design of structures, rectangular and upright triangular shaped buildings and towers are more preferred because of their regular shape. To build tall skyscrapers like the Taipei 101, the floor area has to be reduced as it goes up. An inverted triangle is the worst type of configuration for a building because it will behave like an inverted pendulum where the inertia forces will be concentrated at the top and there is very little resistance to lateral movements. The overturning moment will be too large such that it can easily be toppled down. Irregularly shaped structures, of course, can still be built provided they are properly modelled, analyzed and designed.

Inspired by the Humpty Dumpty music, I created a short video clip about the damaged buildings during the 1990 Luzon Earthquake. Humpty Dumpty here represents Luzon and its damaged structures. Perhaps, nursery rhymes and children songs may be a good way of introducing Disaster Awareness and Preparedness to kids.
The idea of this blog was inspired from Henry Petroski’s book, “To Engineer is Human.” Petroski argues that “the ideas of engineering are in our bones and part of our human nature and experience.” This is a good book specially for non-technical people who wants to understand concepts of engineering design.

Bridge building is a fun and challenging activity. By applying basic strength of materials and bridge design principles, a little creativity and a lot of patience, you can create your own masterpiece similar to the CES bridges shown. So why not test your skills on popsicle stick bridge building by joining the 5th DLSU CES Bridge Building Competition? The competition is open to all civil engineering students in the Philippines. The best bridge design wins P5,000. The bridge with the largest “stiffness/weight ratio” wins P10,000. Check-out the rules in the ads shown in this blog site.

The other CE professor is Prof. Romeo A. Estanero who retired in December 2007 after more than 21 years of teaching at De La Salle University – Manila. Prof. Estanero or popularly known as Doc E was not my professor but he is a colleague in the profession. He was the CE Department chair when I applied for a teaching position at DLSU in 1994. I have observed Doc E when he delivers his lectures in the classroom and in conferences - it was informative, lively and full of animated body language. His whole body is a teaching aid – he bends, sways, wiggles when he teaches topics such as buckling behavior of columns or traffic loads in bridges. He is innovative and up-to-date in his teaching. He uses models and posters in structural design courses. He enhances the teaching of RC design through laboratory destructive testing of concrete beams. Doc E used computers effectively in the classroom via powerpoint presentations and spreadsheet computations. I can still remember when Doc E had a mild stroke - he just took a one month sick leave and then continued his teaching at DLSU until his retirement - that's dedication! Doc E, although he has retired from teaching, continuously inspires young students and engineers in various CE seminars.
Joedec and Doc E are two great and outstanding Filipino professors in civil engineering. For them, teaching and learning are lifelong endeavors.

I started teaching at De La Salle University - Manila in 1994 after earning my Doctor of Engineering in Civil Engineering from Japan. I served as the chair of the department for about three years. I feel proud to have shared my knowledge to many outstanding students who are now building their futures as professionals.
Hey, La Sallian alumni civil engineers - share us your unforgettable moments and teachers during your stay at DLSU. POST your Comments!
