摘要:
应用正交各向异性弹性薄板理论分析了钢筋混凝土剪力墙在框架梁传递来的平面外弯矩作用下的力学行为,得到了节点的转动刚度和墙体有效计算宽度的解析表达式; 引入了“等效框架”分析模型,将节点区附近有效计算宽度范围内的墙体视为一等效框架柱进行分析即可反映节点的平面外转动刚度问题; 并将理论解与ANSYS有限元解进行比较,结果符合较好; 对实际工程情况进行了算例分析。计算结果表明:框架梁-剪力墙平面外连接节点的转动刚度较大,还不能达到可以忽略的程度。
Abstract:
Based on the orthotropic elastic thin plate theory, the mechanical performance of shear wall subjected to non-planar bending moment acting from the beam was studied. The analytical solutions for rotational stiffness of the joint and effective width of the wall were obtained. An equivalent frame model was introduced. The out-of-plane rotational stiffness of the joint can be derived by assuming that an effective width of wall near the joint was acted as an equivalent column. The theoretical results were compared with the finite element results obtained by ANSYS and good agreements were found. Based on practical engineering situation, the results of calculation show that the rotational stiffness of the non-planar beam-wall joint is not small enough to be neglected.
