摘要

为了研究新型结构体系-密肋复合墙结构在近断层地震作用下的地震响应,基于密肋复合墙结构试验,建立该结构的简化计算模型.输入改变控制参数的不同近断层地震动,进行结构非线性地震反应分析.并对同等条件下密肋复合墙结构与框架剪力墙结构在近断层地震作用下结构耗能分配系数对比分析.结果表明,由于密肋复合墙结构独特的构造特点,使其在近断层地震动作用下表现出良好的耗能减震能力,是一种较理想的抗震建筑结构新体系.%In order to study the seismic response of a new earthquake-resistance structural system, a multi-ribbed composite wall structure subjected to near-fault ground motions will be examined. Based on a number of experiments conducted on multi-ribbed composite wall structure, a simplified computational model structure is proposed in the research study. The non-linear structural seismic responses are studied by inputting different near-fault ground motions with varied controlling parameters. Under the same conditions, energy dissipation and distribution parameters are compared between multi-ribbed composite wall structure and frame shear-wall structure. The conclusion illustrates, based on the unique construction, the multi-ribbed composite wall structure has good performance of energy dissipation, vibration reduction, and is considered to be a new ideal seismic structure system.
