摘要:
利用ANSYS软件建立了CFRP-薄壁圆钢管混凝土组合短柱、钢管混凝土柱、素混凝土柱对比柱的三维有限元模型,并对比分析上述3种构件在轴压作用下的延性和极限承载力的差异.研究结果表明:CFRP-薄壁圆钢管混凝土柱的极限承载力比钢管混凝土柱有较大提高(模拟的单层粘贴构件约提高11%,双层粘贴构件约提高25%),且整体刚度好,表现为弹性阶段轴向位移小,当CFRP断裂后,钢管能继续提供塑性支持; 钢管混凝土柱的极限承载力比素混凝土柱提高约4倍,延性也得到很大改善; ANSYS模拟值与文献[1]中的试验值和计算值吻
Abstract:
We established the three-dimensional finite element model of CFRP-thin-wall round steel tube composite short column, Concrete filled steel tube column, plain concrete column by the ANSYS software, and contrastive analysis the difference of ductility and ultimate bearing capacity of the three artifacts under the axial force. The results showed that: The Ultimate bearing capacity of the CFRP-thin-wall round steel tube composite short column was largely enhanced than that of the Concrete filled steel tube column(The simulation component in this paper single-layer paste increased by 11%, double paste by 25%), and the overall stiffness is good which show up as the small axial displacement on the elastic stage, after the CFRP broke, the steel pipe could provide constant support. The Ultimate bearing capacity of the Concrete filled steel tube column can be enhanced about 4 times than that of the plain concrete column, and the ductility also had been improved greatly. The Simulation result of the ANSYS can match well with the test result and the calculation result of the literature [1].
