地震动特性对框剪结构地震能的影响分析
|
摘要
基于能量平衡原理,运用PERFORM-3D软件对钢筋混凝土高层框剪结构在强震作用下的弹塑性能量响应进行了分析,研究了地震动强度、频谱特性和强震持时等特性对于地震的总输入能、总滞回耗能和总阻尼耗能以及滞回耗能和阻尼耗能占总输入能的比例的影响规律。研究表明:地震动特性对于高层框剪结构地震输入能量及其分量影响显著,在基于能量抗震分析与设计时应引起足够重视。
Based on the seismic design method,used the PER FO R M-3D analysis program to analyze the elastic-plastic energy response of tall reinforced concrete frame-shearwall structures under severe earthquake,studied the influence rule of the ground motion intensity,seismic spectrum and the duration of ground motion characteristics to seismic total input energy,total hysteretic energy dissipation,total damping energy and ratio of hysteretic energy dissipation and damping energy to total input energy. The research shows that: seismic spectrum characteristics have great influence on tall reinforced concrete frameshearwall structures in the aspects of the total seismic input energy and its distribution. For the seismic analysis and design based on energy balance principle,enough attention is needed.
