直接基于位移的钢骨混凝土剪力墙结构抗震设计方法研究
|
摘要
对钢骨混凝土剪力墙结构直接基于位移的设计方法进行了研究。提出将型钢混凝土结构的性能水平划分为"使用良好、生命安全、防止倒塌"三个性能水平,通过统计分析提出了钢骨混凝土剪力墙结构各性能水平的层间位移角限值,然后通过钢骨剪力墙结构的侧移模式求出目标位移,将多自由度体系转换为等效单自由度体系,由结构位移反应谱得到等效周期,从而得出结构基底剪力,对钢骨剪力墙进行承载力和变形能力设计。通过算例介绍了该设计方法的全过程,并用静力弹塑性分析方法进行了验证,说明了方法的可靠性。为钢骨混凝土剪力墙结构直接基于位移的抗震设计提供了一个可供参考的思路。
The direct displacement-based seismic(DDBSD) design method is researched on steel reinforcement concrete(SRC) wall building.The seismic performance of steel reinforced concrete(SRC) structures can be induced into three levels: normal service,life safety and collapse prevention.The drift angle of different seismic performance level is recommended through statistical analysis.The target drift is determined according to lateral displacement model of SRC wall building.The multi-degree-of-freedom system is transformed into an equivalent single-degree-of-freedom system;the equivalent period is calculated by displacement spectrum of the structures.Then,the base shear load is obtained to design the building.An example is taken to illustrate the application of proposed procedure and the reliability of method has been verified by pushover analysis.It provides a valuable thought for DDBSD method of SRC wall building.
