【摘要】 传统的结构抗震设计方法需要设计者凭经验来试算抗侧刚度,被动且耗时、费力。本文基于振型分解反应谱理论,提出了主动控制结构抗侧刚度的计算方法,严格推导出求解控制刚度的迭代公式,并证明高层建筑结构各层层间位移达到最大层位移限值时其刚度分布即为最优。针对实际情况,提出了高层结构优化设计的建议。更多还原

【Abstract】 The traditional seismic design method of buildings needs designer to assume the stiffness and then to check it.It is time-consuming and hardness.Designer is passive.Owing to initiatively mastering the deformations,the paper introduced a method,which was based on decomposition response spectrum theory to compute the stiffness of given layers deformations,and then proved that the stiffness was optimal.In the end,the suggestion on optimal design of tall building was given.更多还原
