利用ADINA的CSRC柱轴压性能数值模拟
Finite Element Analysis of CSRC Columns Under Axially Loading Based on ADINA
摘要
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- ADI-NA,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.关键词
