摘要
对4根GFRP管-混凝土-钢管组合柱(DSTC)进行偏压实验,且对20个模拟试件进行有限元分析.通过分析不同长径比对偏心受压组合柱力学性能的影响规律结果表明:组合柱在相同偏心荷载作用下,随着长径比的增加,试件极限承载力逐渐减小,极限位移逐渐增大.
Experimental study was carried under eccentric compression of 4 GFRP-Concrete-Steel double skin tubular columns(DSTC)and 20 simulated specimens of finite element were analyzed.The results show that under the same eccentric load,the ultimate bearing capacity decreases and the ultimate displacement increases gradually with the increase of length-diameter ratio.
