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.
