【摘要】 将钢筋混凝土结构离散为能模拟梁、柱、墙抗震性能的单元,采用串并联刚片系振动模型,体现空间各构件的协同工作,采用改进的Wilson-θ法。对鞭梢效应在高层建筑结构抗震中的影响作详细分析,做到合理利用鞭梢效应,从而可以解决高层建筑物中层间位移起决定性作用的问题,达到合理、经济的效果。更多还原

【Abstract】 On the assumption that spatial building structures may be idealized as the assemblage of planar substructures interconnected by infinitely rigid floors, a method is presented for 3-D nonlinear dynamic analysis on whipping effect in order to make rational and economic design,which can reduce the seismic influence on tall building structures.更多还原
