【摘要】 采用MSC.MARC有限元软件,模拟4片不同形式的钢筋混凝土网格墙试件低周反复试验全过程。对于不带构造柱网格墙,采用分层壳单元进行模拟分析;对于带边缘构件的网格墙及带翼缘L型网格墙,在分层壳单元基础上,采用THUFIBER程序中的纤维单元对构造柱进行模拟。仿真结果表明,数值模拟得到的滞回曲线的形状、峰值应力、开裂情况等,均与试验结果吻合较好;验证了网格墙有限元模型的有效性,为网格墙体系的弹塑性分析打下基础。更多还原

【Abstract】 The whole process of reversed cyclic loading tests of four reinforced concrete grillage wall specimens with different forms were simulated based on the software MSC.MARC.For the grillage wall without constructional columns,the layered shell element is used for simulation during the analysis.For grillage wall with constructional column and L type grillage walls with flange,the fiber element of THUFIBER program was used to simulate the constructional columns.The simulation results show that hysteretic curves,peak stress and cracking mode match well with the experimental results.The validity of grillage wall finite element model is verified,which lays the foundation for the elasto-plastic analysis of the grillage wall system.更多还原
