摘要
在计算地震荷载中,设计的依据是常规反应谱理论。然而,当质点间出现刚体移动时,用上述理论计算会出现奇异点。本文利用相对加速度进行计算,将常规反应谱理论进行修正,所得结论既偏于安全,又弥补常规反应谱的不足。
Generally, the computing of earthquake loading is based on the regulation response spectrum theory. However, when there are rigid bodies moving among particles, singularity may appear in the computing mentioned above. By the computing based on the relative acceleration, this paper revised regulation response spectrum theory. The results in the paper emphasis on safety, and can compensate for the limitation of the regulation response spectrum theory.
