Research of Dynamic Characteristics for the Frame-shear Wall Struture by using Concisely Lateral Stiffness Matrix

本文采用柔度法建立框架剪力墙结构的简约抗侧移刚度矩阵,利用雅可比迭代法计算结构体系的自振频率和周期,再利用振型分解反应谱法计算体系在水平地震作用下的各层内力,为实际工程的分析和设计提供理论依据。并运用Fortran语言编制PRST通用计算程序实现电算,较其他方法更为方便快捷。

By using flexbility method worked out the concisely lateral stiffness matrix of the Frame-shear wall.By using Jacobi method can work out the vibration modes and periods of the structure hierarchy,and by using the analysis of Response Spectrum Technique can got the internal force of every floor.It can provides a certain theoretical basis for the analysis and designing.PRST universal program is maken by using Fortran language.It can be work out conveniencely by using computer algorithm.
