The present paper presents a comparison of seismic provisions of three seismic design codes, the Philippine code, Eurocode 8 and the American code, to the most common ordinary residential frames of standard occupancy. Regular and irregular reinforced concrete frames were analyzed and compared for four storey building types. The response spectrum and the seismic parameters of NSCP 2010 were considered for the horizontal load action with different load combinations. Response spectrum analysis and

Based on the results of column axial load -bending moment interaction diagrams, EC8 was found to be conservative when compared to NSCP 2010 and 2009 IBC. The conclusion is that for the design and analysis of ordinary RC residential buildings with certain irregularity, EC8 provisions were considered to be safer.
