摘要
应用ANSYS结构有限元分析软件,选择三维八节点的混凝土单元Solid65模拟灌孔砌块砌体、杆单元Link8模拟钢筋,针对竖向偏心荷载作用下的配筋砌块短肢砌体剪力墙进行了三维非线性有限元分析,研究了该类墙体的破坏形态、承载与变形能力,并将模拟结果与试验值进行了对比,验证了有限元分析方法的可行性。在得到可靠验证的基础上,进行了扩大参数分析,研究了不同偏心距对承载力的影响。
Nonlinear FEM program ANSYS is adopted to simulate the reinforced block short - leg masonry shear wall with eccentric compressive load. The 3D 8 nodes concrete element solid65 is adopted to simulate the masonries and button stems. The 3D spar element link8 is adopted to simulate the rebar. In this paper, the failure mode, the bearing capacity and the deformation of the walls were studied. The simulated results have been compared with the test and the feasibility of FEM method was validated. On the base of the reliable verification, the effect of different eccentricity carrying capacity of the wall was studied by means of extensive parametric analysis.
