| 摘 要： | 开展了3个混凝土单层空间框剪结构模型的拟静力试验,考察了它们在楼板参与作用下的破坏过程,并与弹塑性分析结果进行了对比,探讨了楼板对抗侧力构件剪力分配的影响.试验和分析结果表明:1)框架梁总体上破坏较晚且破坏程度明显小于剪力墙和框架柱；2)水平荷载作用下剪力墙附近楼板损伤较大,该处楼板钢筋承受较大拉应力；3)考虑实际楼板...

| Abstract: | Pseudo-static tests of three one-storey spatial RC frame-shear wall structures with floor slabs were conducted to investigate their failure modes and hysteretic behaviors. The test results were compared with those of pushover analysis. It is shown that: 1) damage of the frame beams occurs later and is less than that of the shear wall and the frame columns; 2) damage of the floor slabs under lateral loading is significant in regions close to the shear wall, and tensile stresses of slabs' steel bars in these regions are much larger; 3) in comparison with the case that the floor slabs are neglected, the maximum lateral load that a frame-shear wall structure can bear is larger in the case that the floor slabs are taken into account, and the contribution ratio of the shear wall also increases; 4) shear forces carried by the frame columns with identical cross sections and reinforcement details but located at different positions are close to each other on the whole. |
