基于APDL的钢板剪力墙可靠性研究

Reliability of steel plate shear wall based on APDL

应用ANSYS中的APDL参数化语言对非加劲肋钢板剪力墙、十字加劲肋钢板剪力墙、斜加劲肋钢板剪力墙进行了建模及随机有限元可靠性分析。在随机有限元可靠性分析中,使用PDS模块,确定了钢板剪力墙的可靠度,并将结果生成可靠性分析报告。结果表明:相同强度地震力作用下的三种模型,可靠度从小到大依次为非加劲肋钢板剪力墙、十字加劲肋钢板剪力墙、斜加劲肋钢板剪力墙。三种模型中竖向压力对可靠度影响最大。

The APDL parametric language of ANSYS is used in the analysis of modeling,buckling,yielding,earthquake response and stochastic finite element reliability for SPSW of un-stiffened,cross stiffened and diagonal stiffened.In the reliability analysis of stochastic finite element,the PDS module is used to determine the reliability of SPSW and to create the reliability analysis report.The results show that: under the same earthquake intensity,the reliability of three models in ascending order is that un-stiffened SPSW,cross stiffened SPSW and diagonal stiffened SPSW.Among all of the factors,vertical loading is the most influencing.
