钢板混凝土单元平面内纯剪受力行为

In-plane pure shear behavior of steel-concrete-steel element

针对钢板混凝土剪力墙单元平面内纯剪情况,通过对其受力行为的分析,给出面内纯剪设计承载力的建议计算式.基于钢材的弹塑性增量本构关系对单元在钢板屈服后的变形发展进行了数值模拟,通过与试验结果的对比,表明给出的推荐计算式对极限承载力有一定的安全储备,对于屈服承载力具有较高的计算精度。

The present paper focuses on the in-plane shear state and proposes a recommended formula through theoretical analysis.Based on the elasto-plastic incremental constitutive laws of steel,the deformation of steel-concrete-steel element after yielding is numerically simulated.By comparing with the results of pure shear tests of a series of steel-concrete-steel panels,it is shown that the recommended formula of in-plane pure shear capacity proposed in the present paper has a certain safety margin to the ultimate bearing capacity,while has high accuracy for the yield bearing capacity.
