摘要:
为了研究复杂建筑结构在地震作用下地震能量的分配与耗散机制，基于能量平衡原理和Perform 3D软件对钢筋混凝土框架剪力墙高层结构模型进行了动力弹塑性能量时程分析，得到了框剪高层结构在罕遇地震作用下地震能量的输入、分布及耗散规律；考察了地震动特性对钢混框剪高层结构地震能量输入及分配的影响，确定了地震耗能占输入能的比例时程；分析了结构阻尼比和结构延性对框剪高层结构地震输入能、阻尼耗能和滞回耗能及其耗能比例的影响规律，确定了阻尼比对滞回耗能和延性比对阻尼耗能的交互影响；研究了框剪高层结构地震滞回耗能沿结构竖向分布和沿横向构件内部分配的规律，确定了竖向刚度分布对结构地震滞回耗能的影响；揭示了钢混框剪高层结构地震输入能量及其分布规律。所得结论可为基于能量平衡原理的抗震设计理论在复杂钢筋混凝土高层建筑结构实际工程中的运用提供参考。
Abstract:
In order to investigate the mechanism of seismic energy distribution and dissipation of complex building structure, the time history analysis of dynamic elastoplastic energy for a reinforced concrete (RC) framewall highrise structure was made by using software Perform 3D based on the principle of energy balance. Mean while, the rule of earthquake input energy and its distribution were obtained for RC framewall structure under rare earthquake. The influences of ground motion characteristics on the earthquake input energy and its distribution in the RC framewall highrise structure were examined, the time histories of the ratios of seismic energy dissipation to input energy were obtained. The influences of damping ratios and ductility ratios on the earthquake input energy, damping energy and hysteretic energy and its ratios to input energy were discussed, and the mutual influences of damping ratios on the hysteretic energy and the ductility ratios on the damping energy were determined. The distributions of the hysteretic energy along vertical direction and among RC members of the building structure were researched, and the effects of lateral stiffness on the hysteretic energy were confirmed for the framewall highrise structure. The rules of earthquake input energy and its distribution among energy components were indicated for RC framewall highrise structure. The obtained conclusion for seismic design theory based on the energy balance principle can provide reference for the engineering practice of complex RC highrise building structure.
