[提要]  日本理化学研究所地震防灾研究中心与加拿大英属哥伦比亚大学的研究人员合作，共同开发和进一步发展了用于研究结构物地震反应的三维分析模型，并采用该模型编制了计算机程序，用于模拟结构物的地震反应，研究地震破坏机理。运用该分析模型的建模方法和对一设有地震仪的钢筋混凝土框架建筑物进行了分析。通过将分析结果与该建筑物在1994年Northridge地震中的记录和损伤情况进行比较，验证了作者所开发的三维分析模型和计算机程序的可靠性。

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.
