有限元分析软件在地震现场评估的可实施性探索

Feasibility of Finite Element Analysis Software in Earthquake Field Structure Assessment

在地震灾害中,现场结构评估是一项十分重要的工作,其应具备快速、精准、科学的三大特点。相比于传统的地震台测试及专家经验法,有限元软件提供了一种评估地震中建筑性能的新方法,具有高性价比及易操作的特点。本项目运用Abaqus分析软件创建废墟模型,并模拟废墟模型在余震中的表现,找到相关分析模型的规律特点,将分析结果与经验法及振动台测试所得数据相比较,有限元软件所得数据及定律具有合理性、真实可用,可为参与现场评估、搜救的救援人员提供建议。因此,可对有限元分析法在现场评估及地震营救教学的作用进行深入探讨。

In earthquake disaster, field structure assessment is a very important work, which should be fast, precise and scientific. Compared with the traditional shaking table testing and empirical method, the finite element analysis(FEA) software provides a new way to evaluate the performance of buildings in earthquake, which is cost-effective and easy to operate. This project creates the ruins model by using Abaqus software to simulate its performance in aftershocks and concludes features of such models. By comparing the results with the data obtained by empirical method and shaking table test, it is found that the laws and data by FEA software are reasonable and true, and can provide suggestions for rescue personnel participating in on-site assessment, search and rescue. Therefore, the FEA software in field assessment and earthquake rescue training should be further discussed.
