混凝土强度不足对剪力墙结构整体性能影响研究

Research into the effect of concrete strength deficiency on the structural performance of shear wall

混凝土强度不足是建设工程中常见的问题,现阶段对于此类问题的研究,多集中在对梁、柱等单个构件上,对于结构整体性能的影响研究较少.以一实际工程为背景,运用SATWE及PUSH&EPDA模块分别对其进行静力弹性及弹塑性分析,通过对比混凝土强度降低前后结构的抗震性能变化,总结混凝土强度不足对剪力墙结构整体性能的影响,为结构加固设计提供依据.

The concrete intensity insufficiency is the common problem in the construction project. In our country , the study for such is- sue focused more on the separate components,and less on the structural overall performance. Based on an actual project with SATWE and EPDA＆PUSH module in PKPM software, the static elastic and elastoplastic properties were analyzed. The calculation results before and after the concrete strength reduction were contrasted, and the effect of concrete strength deficiency on structural performance was summarized, providing the basis for structural reinforcement design.
