【摘要】 采用子结构Rayleigh阻尼模型构造隔震结构的非比例阻尼矩阵 ,用FORTRAN语言实现结构的动力时程分析。为便于工程应用 ,用VB语言开发了前后处理界面与FORTRAN链接 ,成为隔震工程专用动力分析软件 (ISDN)。用本软件和Simulink以及复振型分解法对一工程实例分别进行计算 ,两者所得位移和加速度的最大相对误差分别不超过其响应最大值的 0 0 7%和 0 2 7%。说明本软件的分析精度满足工程设计要求更多还原

【Abstract】 Non-proportional damping matrix of isolated structure is formed on the basis of Rayleigh damping model,and dynamic response of structure is analyzed with a FORTRAN program.For the convenience of design,input and output interface are made by VB.The software ISDN can analyze dynamic response of the isolated structures.Applying the software and Simulkink to a prototype structure,the rlative maxiumum errors of displacement and acceleration are less than 0 07% and 0 27%.It is shown that the analysis precision of software is fit for engineering design.更多还原
