基于OpenSees的钢筋混凝土剪力墙数值分析
Numerical analysis of reinforced concrete shear wall based on OpenSees
摘要
Abstract
The finite element numerical simulation is an effective method to study the seismic performance of reinforced concrete shear wall,and the selection of different numerical analysis model has a great influence on the seismic performance of reinforced concrete shear wall.The finite element software OpenSees is used to establish the numerical analysis model of reinforced concrete shear wall under different axial compression ratios,the fiber models based on the beam with hinges element and the displacement based on beam column element are simulated respectively. Meanwhile, the constitutive model of material is analyzed,the low cyclic loading test of reinforced concrete shear wall is presented,and the simulation results are compared with the test results.The results indicate that the reinforced concrete shear wall is controlled by flexural deformation,the hysteresis loop is full,the energy consumption is better and has better seismic performance. With the increase of axial compression ratio,the yield load and ultimate load of the specimens increase significantly,and the ductility coefficient decreases a little.The fiber model based on the beam with hinges element can better simulate the seismic performance of the reinforced concrete shear wall when the plastic section is determined reasonably.The error of the yield load,ultimate load and the ductility coefficient based on the beam with hinges element is controlled within 10%.The error of the yield load is over 20%and the error of the ultimate load is controlled within 10%,which are based on the Displacement-Based Beam-Column Element.关键词
