Evaluation des methodes reglementaires de determination des deplacements sismiques par analyse dynamique non lineaire

摘要

A study is carried out to evaluate the storey drift evaluation methods of the seismic code of Algeria (RPA 99) and France (PS 92) for multi-storey steel rigid-frame buildings with set-back towers. The evaluation is based on a comparison of the storey drift obtained from the procedures of codes with those obtained from the nonlinear dynamic analysis of the buildings with set-back and a uniform building served as a reference. The results of the nonlinear dynamic analysis show in particular that the code methods of RPA 99 and PS 92 lead generally to an underestimation of storey drifts for the "tower" portion but provide such estimates of those for the "base" portion.
