摘要
为探究PKPM与YJK两款结构设计软件中地震计算的差异,并为工程师选择结构设计软件提供参考,采用PKPM与YJK两款结构设计软件中的5种特征值求解方法(YJK的WYD-Ritz法,Lanczos法以及Ritz向量法,PKPM的子空间迭代法与多重Ritz向量法)对某实际工程进行结构分析,对比了结构周期、基底剪力、有效质量系数及软件的计算效率,并对其中的差异进行了探讨。
In order to explore the difference of seismic analysis in PKPM and YJK and provide structural engineering with some reference when they choose the structure design software,five kinds of eigenvalue methods （WYD-Ritz,Lanczos,Ritz-Vector in YJK and subspace iteration,mul- ti-Ritz-Vector in PKPM）of PKPM and YJK were applied to analyze the structure of an engineering case. The period,base shear,effective mass coef- ficient of the structure and the computational efficiency of the software were compared,and the difference between them is discussed as well.
