改进的剪力墙等代框架模型分析

Analysis on Refined Model-equivalent Model for Shear Wall

框架-剪力墙结构作为一种重要的结构形式,对其弹塑性性能的研究已日渐普遍。多数结构分析软件可以为框架线单元设置塑性铰,没有为壳单元的塑性分析提供塑性铰,工程设计人员无法直观地了解结构中剪力墙的屈服状况。该文设计一种改进的等代框架模型,可以较好地等代两端带有翼缘或边柱的剪力墙构件,为框架-剪力墙结构中带边柱或翼缘的剪力墙的弹塑性分析提供相关参考。

The frame-shear wall structure is an important structural form, whose elastic plastic performance is being more widely studied. Frame plas-tic-hinge can be set up through most structural analysis software, but not for shell element. Project planners have no intuitive grasp of the yield state of the shear wall structure. This paper puts forward an improved equivalent frame model, which can better equivalent the shear walls with side columns and flanges. It can provide relevant references for similar structures.
