Elastic-Plastic Analysis and Application of
Reinforced Concrete Shear Wall
Abstract:The paper introduces various plastic models of structure members in PERFORM-3D, pares the results calculated by PERFORM-3D with the test data by other researches, including some single shear walls and reinforced concrete core wall, paring results show that PERFORM-3D can effectively simulate the force and deformation characteristics of reinforced concrete shear wall’ plastic properties. Through the nonlinear time history analysis of a frame core-tube and high-rise buildings under severe earthquake, evaluates the seismic performance of the structure, and describes the application of PERFORM-3D in the structural seismic analysis and evaluation process.
Key words:PERFORM-3D, shear wall, elastic-plastic time history analysis, evaluation of seismic performance
0引言
PERFORM-3D三维结构非线性分析与性能评估软件是由美国加州大学Berkeley分校的鲍威尔教授(Prof. Graham H. Powell)在Drain-2DX和Drain-3DX的基础上发展而来,使用以变形或强度为基础的极限状态,致力于对结构进行抗震分析和性能化评估,其分析结果得到了国际学术界和工程界的广泛认可,尤其是对错综复杂的剪力墙体系,能为使用者提供其他软件一般不具备的动力弹塑性分析功能,既可以用于工程设计,也能用于对新软件进行测试和对实验结果进行校核。
本文将对PERFORM-3D的基本单元进行介绍,并通过与试验对比来检验其结果的合理性,最后运用PERFORM-3D对某超高层建筑进行弹塑性时程分析和性能评估
