型钢高性能混凝土剪力墙受剪承载力试验研究

Experimental study on shear bearing capacity of steel high performance concrete shear walls

为了研究型钢高性能混凝土剪力墙受剪性能,进行了3片剪力墙试件水平加载试验,试件均发生剪切破坏,对影响其破坏形态、承载力及延性的主要因素进行了分析。根据试验结果,在我国现行《型钢混凝土组合结构技术规程》的型钢混凝土剪力墙受剪承载力计算公式基础上,提出型钢高性能混凝土剪力墙受剪承载力计算公式,通过计算结果与试验实测结果的对比,提出的公式能较好地反映试验结果,且计算结果偏于安全。

To study shear behavior of steel high performance concrete shear walls,three specimens of shear walls were tested and shear failure occurred on all specimens.The main factors that influence on its failure pattern,bearing capacity and ductility were analyzed.Combined with experimental results,on the basis of calculation model of steel reinforced concrete shear walls in the current Technical specification for steel reinforced concrete composite structures,a calculation formula for shear bearing capacity of steel high performance concrete shear walls is presented.According to the comparison between experimental results and calculation results,it is found that the calculation formula coincides with the experimental results well,and calculation results tend to be safe.
