偏心受压下混凝土强度对GFRP管-混凝土-钢管组合柱力学性能的影响
Research on the Effects of Concrete Strength on the Mechanical Properties of GFRP-Concrete-Steel Double Skin Tubular Columns Under Eccentric Compression
摘要
Abstract
In order to study the effect of concrete strength on the mechanical properties of DSTC com-posite columns,nine DSTC composite columns were simulated under eccentric compression using finite ele-ment software ANSYS by means of equivalent stress nephogram,bearing capacity and load-displacement curve.The results show that with the increase of concrete strength,the bearing capacity increases obvious-ly,but the ultimate bearing capacity decreases gradually.The higher the concrete grade is,the worse the ductility becomes.When the concrete grade is lower,the impact of steel content on ductility is obvious and the restraint effect of GFRP tube gradually decreases with the increase of concrete strength.关键词
