[提要] 采用子結(jié)構(gòu)Rayleigh阻尼模型構(gòu)造隔震結(jié)構(gòu)的非比例阻尼矩陣,用FORTRAN語言實現(xiàn)結(jié)構(gòu)的動力
時程分析。為便于工程應用,用VB語言開發(fā)了前后處理界面與FORTRAN鏈接,成為隔震工程專用動力分析軟件( ISDN)。用本軟件和Simulink以及復振型分解法對‘工程實例分別進行計算,兩者所得位移和加速度的最大相對誤差分別不超過其響應最大值的0.07%和0.27%。說明本軟件的分析精度滿足工程設計要求。
[關(guān)鍵詞] 基礎隔震 非比例阻尼 動力分析 ISDN軟件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 ancl 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.
