也门共和国典型桥梁的地震易损性分析
发布时间：2023-08-20 09:52
1982年在达马尔市的地震是自1811年也门历史上的地震事件以来强度最大的,这让工程部门注意到许多已建立的高速公路桥梁延伸出瑕疵和裂缝。然而,这种意识和关心直到1990年也门统一之后都没有解决,那时也门统一地区超过了萨那的地震区,并处于也门共和国中部和东南部等中强地震区。对中强地震区与桥梁相关的地震问题的这种长期忽略,导致一系列桥梁在防震设计方面存在许多不足之处,为了更长久和有效地使用桥梁,必须对桥梁进行评估和审查。最近,一种新兴的决策工具在地震风险评估研究中变得越来越流行,叫做地震易损性曲线。在也门这五种类型的桥梁被定义为:本研究的目的是改进一种有趣的方法,用于研究也门中部和东南部地区典型桥梁的地震易损性曲线数据。虽然已有对地震易损曲线的研究,但大多数都集中在也门西部和叙利亚的高地震带的桥梁。由于认识到大规模地震的可能性,现在重心更多放在也门地区。为帮助评估该地区的地震危险性,选择了五种典型的桥梁来研究地震易损性曲线:1-多跨支撑连续混凝土梁2-多跨支撑连续钢梁3-多跨支撑连续板4-多跨支撑连续混凝土箱梁5-多跨支护简支混凝土梁这五种桥梁占该地区160,000多条高速公路桥梁的近90...
