方钢管再生混凝土组合异形柱偏压力学性能及参数化分析
Eccentric mechanical properties and parametric analysis of recycled concrete composite special-shaped columns made of square steel tubes
摘要
Abstract
Aiming at the influence of recycled coarse aggregate replacement rate on the mechanical properties of square steel tube recycled concrete composite special-shaped columns under eccentric compression,based on the existing test results,the verified finite element method was used to analyze the mechanical properties of this kind of special-shaped columns under eccentric compression load.The results show that the eccentric compression bearing capacity of square steel tube recycled concrete composite special-shaped columns decreases with the increase of coarse aggregate replacement rate.When the replacement rate of coarse aggregate exceeds 40%,the downward trend of bearing capacity is more significant.Under the condition of the same coarse aggregate replacement rate,increasing the yield strength of steel or increasing the thickness of steel can effectively enhance the overall stability of the specimen and improve its eccentric bearing capacity.Increasing the width of the connecting plate will weaken the stability of the specimen,resulting in a decrease in the bearing capacity.关键词
