保温墙模复合剪力墙试验研究

Experimental Study on Complex Shear Wall with Heat Preservation Formwork

针对免拆保温墙模复合剪力墙体系开展试验研究。通过复合剪力墙及普通剪力墙轴压试验,确定单片复合剪力墙在轴向压力作用下的承载能力,了解复合剪力墙的破坏形态、变形能力。试验表明免拆模复合剪力墙在屈服之前表现出良好的承载力,其破坏首先发生在连梁处,破坏时持续的时间较长。通过平面外位移分析表明,复合带缝剪力墙具有很好的整体工作性能及平面外稳定性。

Experimental study on complex shear wall structure with heat preservation formwork was engaged in. Based on the complex shear wall and common shear wall specimens experiment under the axial loading, some characteristics of the new structure were analyzed, including the bearing capacity, failure mode, distortion capability. The experiment results show that complex shear walls have excellent bearing capacity before yielding, and the duration between yielding to failure is longer. Its failure crack occurred at the connect beam firstly. Displacement analysis shows that complex shear wall has enough outer plane stability, and has perfect work behaviors as a whole.
