摘要
为了解冷弯薄壁型钢双层组合墙体的力学性能,采用ANSYS软件建立了有限元模型,考虑轴压、柱的截面尺寸、不同材料面板和楼盖梁数量,对4组共11个双层组合墙体进行了低周往复加载模拟。结果表明:⑴随着轴压的增加,墙体的承载力逐渐减小,变化幅度由大变小,延性系数减小;⑵仅在截面尺寸变化时,截面尺寸增加,墙体的承载力提高;⑶墙面板有明显的蒙皮效应,硅酸钙板的墙体承载力较高;⑷增加楼盖梁数量可以提高墙体承载力。
To understand the mechanics performance of double-deck composite wall with the cold-formed thin-walled steel,a finite element model was established by ANSYS software.With axial compression,column section size,different material panel and number of floor beam considered,low-cycle reciprocating load simulation was carried out in a total of 11 double walls in four groups.The results show that:⑴With the increase of axial pressure,the bearing capacity of the wall gradually decreases,so does the ductility coefficient;⑵Only when the cross-sectional size increases,the wall bearing capacity increases;⑶The wall panel has obvious skin effect,and the wall bearing capacity of calcium silicate board is higher;⑷ The increase of the number of floor poles can enhance the wall bearing capacity.
