Abstract: “The main target of this research work is to show the differences of the National Structural Codes of the Philippines (NSCP) Seismic provisions of the 2 codes-- NSCP 1992 and the new one, NSCP 2010. In order to work out for the main differences of the Design Base Shear (V), the Linear Static Analysis (LSA), which is considered as the Static Lateral Force Procedure and the Response Spectrum Analysis (RSA), another method specified in the NSCP codes under the Dynamic Lateral Force Procedure were carried out to analyze a Three Storey Reinforced Concrete Public School Building. In the Dynamic Analysis, the maximum ground motion intensity, such as the peak ground acceleration (Amax) of the earthquake is considered. The outcome of this research work is an indispensable tool for Structural Designers who will assess the seismic hazard of existing buildings designed under the NSCP 1992 in terms of their structural integrity. While the structural designers’ liability is not limited to design flaw”
