Seismic hazard prediction is essential for earthquake preparation in urban areas. Prediction methods based on refined the finite element method (FEM) models and time-history analysis require higher calculation, which is hard to apply universally. In this paper, by applying two simplified models and time-history analysis, the authors were able to develop a refined seismic hazard prediction system for urban buildings using MATLAB and OpenSees. The system is modular in design with a unified data interface to transfer data, where only the macro parameters of buildings are required to complete the computation work. Taking the campus of Tongji University as a test area, the system was applied to predict seismic hazard and compare it with the results of the vulnerability method by applying the seismic damage index to verify its reliability. The results show that the system can meet the needs of accuracy, efficiency, and visualization of seismic hazard prediction in urban areas.

基于时程分析的城市建筑地震危险性预测系统

地震危险性预测对于城市地区的地震预防至关重要。基于改进的有限元方法（FEM）模型和时程分析的预测方法需要较高的计算量，难以普遍应用。在本文中，通过应用两个简化模型和时程分析，作者能够使用MATLAB和OpenSees开发出完善的城市建筑地震危险预测系统。该系统采用模块化设计，具有统一的数据接口来传输数据，仅需建筑物的宏观参数即可完成计算工作。该系统以同济大学校园为试验区，通过地震破坏指数验证其可靠性，将其用于预测地震危险性并将其与易损性方法的结果进行比较。
