Evaluation of the Floor Acceleration Amplification Demand of Instrumented Buildings

The floor acceleration amplification (FAA) factor is one of the most critical parameters in computing equivalent seismic force nonstructural component (NC). To evaluate heightwise FAA distribution profile, recorded response instrumented buildings was analyzed using California Strong Motion Instrumentation Program (CSMIP) database. demands for three groups consisting reinforced concrete, steel, and masonry were analyzed. In each group, classified into four subgroups according to their heights. Parabolic profiles suggested that could envelop data, as demonstrated by processed results. An earthquake experience-based importance terms percentage enveloped records. obtained FAAs at roof generally larger than those other levels. percentile distributions (RAA) computed. results showed underestimated ASCE 7-16. magnitudes RAA correlated fundamental period building, which considered classifying ranges. profile against from a regression analysis. developed expected be useful design NCs, it adopted future code provisions.
