摘要
采用ABAQUS软件中非线性分析常用实体单元C3D8R模拟混凝土框架和砌体填充墙,杆单元T3D2模拟钢筋,弹簧单元SPRINGA模拟框架和填充墙体的连接,弹簧单元SPRING1模拟填充墙与地面的连接,建立了带竖缝砌体填充墙框架结构的有限元非线性分析模型。对1榀裸框架结构模型和3榀带竖缝砌体填充墙框架结构模型的性能进行了非线性有限元分析,并与试验结果进行了比较。分析表明,理论值与试验值符合较好,说明所建立的有限元分析模型可以较好地模拟带竖缝砌体填充墙框架结构的性能,为进一步分析这种结构的性能提供基础。
The reinforced concrete frame and masonry infill panels were simulated by the common solid element C3D8R in the non-linear finite element analysis model of the ABAQUS software,the reinforcement was simulated by the truss element T3D2,the connection between the reinforced concrete frame and masonry infill panels was simulated by the spring element SPRINGA,the connection between the masonry infill panels and the ground was simulated by the spring element SPRING1,then the paper set up the model of the non-linear finite element analysis of reinforced concrete frame structures with slit masonry filler walls.Behavior of 1 reinforced concrete frame and 3 reinforced concrete frame with slit filler panels was analyzed by the nonlinear finite element analysis,and the analytical results were compared with the experimental ones.The analysis showed that the theoretical values are in good agreement with the experimental values,the behavior of the reinforced concrete frame with masonry infill panels can be simulated by the finite element analysis model proposed in this paper,which provides basis for the further analysis of the performance of the structure.
