钢筋混凝土框架斜撑结构动力弹塑性分析

Dynamic Elastoplastic Analysis of Reinforced Concrete Frame Structure with Braces

运用有限元原理,对框架结构、框架斜撑结构和框架-剪力墙结构进行动力弹塑性时程分析。通过YJK软件,将3种结构在相同地震波作用下进行模拟验算。结果表明:框架结构在相同地震波作用下侧移值最大,框架-剪力墙结构最小,框架斜撑结构位于两者之间;通过合理加设钢筋混凝土斜撑可提高结构的抗变形能力,提高框架的高度限制。

The frame structure,frame brace structure and frame-shear wall structure dynamic elastic-plastic time history are analyzed by using the finite element theory.Through YJK software,the three kinds of structures are calculated in the action of seismic wave.The results show that frame structure with the action of same seismic waves had maximum lateral value,frame-shear wall structure has minimum lateral value,frame bracing structure has medium lateral value;By reasonable adding the RC bracing,the deformation resistance of the structure is improved,and the height restriction of the framework is improved.
