不同参数下钢筋混凝土空心柱力学性能研究
Research on different parameters of RC hollow column on mechanical properties
摘要
Abstract
To study the failure mode and mechanical properties of reinforced concrete(RC)hollow columns with different parameters,the RC hollow columns under static horizontal loads were simulated using nonlinear analysis program Matlab and finite element software program ABAQUS.The accuracy of the simulated was verified by the comparison between the results of Matlab analysis and Abaqus.Some parameters including the axial-load ratio,height-width ratio,width-thickness ratio,reinforcement ratio, stirrup ratio are studied.The results showed that the horizontal bearing capacity of hollow columnin creased at beginning with the increase of axial-load ratio,but when the ratio reached 0.4,the capacity declined as following.The height-width ratio,width-thickness ratio,reinforcement ratio,stirrup ratio had a great influence on the seismic performance and failure mode,which provided reference for practical engineering design and application.关键词
