[提要] 日本理化學(xué)研究所地震防災(zāi)研究中心與加拿大英屬哥倫比亞大學(xué)的研究人員合作，共同開發(fā)和進(jìn)一步發(fā)展了用于研究結(jié)構(gòu)物地震反應(yīng)的三維分析模型，并采用該模型編制了計算機程序，用于模擬結(jié)構(gòu)物的地震反應(yīng)，研究地震破壞機理。運用該分析模型的建模方法和對一設(shè)有地震儀的鋼筋混凝土框架建筑物進(jìn)行了分析。通過將分析結(jié)果與該建筑物在1994年Northridge地震中的記錄和損傷情況進(jìn)行比較，驗證了作者所開發(fā)的三維分析模型和計算機程序的可靠性。
[關(guān)鍵詞] 三維非線性動力分析 多彈簧模型 框架 地震反應(yīng) 破壞機理To evaluate the seismic behavior and damage of reinforced concrete(RC) buildings subjected to strong ground motion with reliable accuracy,sophisticated analysis model and 3D nonlinear analyses are generally recommended. A 3D nonlinear dynamic analysis computer program is being used for the investigation of structural earthquake responses and damage mechanisms. The reliability of the analysis model and the computer program are verified by investigating the dynamic response of an instrumented building that has recorded the motions of several earthquakes.This paper discusses the capabilities of this computer program and shows the modeling techniques which calculate responses are in good agreement with the recorded motions during a strong earthquake.
Keywords: 3D nonlinear dynamic analyses; MS model; frame; earthquake response
