摘要:
通过6个核心型钢混凝土CSRC柱试件的轴压性能试验,并利用高级结构非线性及流固耦合计算系统(ADINA)进行10个试件的有限元数值模拟试验,研究不同配箍特征和配钢率对混凝土柱轴心抗压承载力及轴向变形性能的影响.试验结果表明,混凝土轴压柱试件配置的配钢率分别为1.63%,2.88%,4.02%,核心型钢的极限承载力可分别提高11.9%,26.8%,40.7%,极限变形可分别提高32.3%,52.0%,75.8%.增加试件体积配箍率可有效提高试件的轴向变形能力,并改变试件的脆性剪切破坏形态为整体压溃.采用不同的混凝土本构建立有限元模型,对比分析表明,计算结果与试验结果吻合较好.
Abstract:
Six core steel reinforced concrete(CSRC) columns were tested under axially loading,and a nonlinear numerical analysis simulating the whole test process of ten specimens is carried out by the finite element method software-ADINA,to investigate the effect of core steel,transverse reinforcement and steel ratio to the axial strength and axial deformation capacity.The test results indicate that axial strength of the specimens is increased by 11.9%,26.8% and 40.7% respectively,and the axial deformation capacity is increased by 32.3%,52.0% and 75.8% respectively,when the ratio of core steel area to the section area is 1.63%,2.88% and 4.02% respectively.Increasing the volume ratio of stirrups can effectively increase the axial deformation capacity,and the brittle shear failure modes of the specimens can also be changed into a more ductile way.The sections of the specimens are divided into constrained region and unconstrained region with different constitutive relationships of concrete to establish the analytical mode.The analysis results indicate that the results of calculation agree well with the test results.
