【摘要】：我国目前尚缺乏合理有效的公路桥梁震害评估模型。为促进我国公路桥梁震害评估系统的发展,基于HAZUS软件中使用的桥梁震害评估模型,对中国公路桥梁进行抗震等级分类,分别以1.0s时的谱加速度、地面峰值加速度和地面永久变形为指标,给出每类桥梁的震害评估模型参数,形成一个初步适用的中国公路桥梁震害评估模型。利用汶川地震后四川地区公路桥梁震害数据对该模型进行验证,结果表明该模型能较为准确地预测震害统计结果,从而证明该模型的合理性和适用性,可以为我国公路桥梁震害评估系统的发展提供一定的借鉴。
[Abstract]:At present, there is a lack of reasonable and effective earthquake damage assessment model for highway bridges in China. In order to promote the development of earthquake damage assessment system for highway bridges in China, based on the bridge damage assessment model used in HAZUS software, the seismic grade classification of highway bridges in China is carried out, with the spectral acceleration of 1.0s, respectively. The earthquake damage assessment model parameters of each kind of bridges are given and a preliminary applicable earthquake damage assessment model of highway bridges in China is formed. The model is verified by the earthquake damage data of highway bridges in Sichuan area after Wenchuan earthquake. The results show that the model can accurately predict the statistical results of earthquake damage, thus proving the rationality and applicability of the model. It can be used for reference for the development of earthquake damage assessment system of highway bridges in China.
