也門共和國典型橋梁的地震易損性分析
發(fā)布時間：2023-08-20 09:52
1982年在達馬爾市的地震是自1811年也門歷史上的地震事件以來強度最大的,這讓工程部門注意到許多已建立的高速公路橋梁延伸出瑕疵和裂縫。然而,這種意識和關心直到1990年也門統(tǒng)一之后都沒有解決,那時也門統(tǒng)一地區(qū)超過了薩那的地震區(qū),并處于也門共和國中部和東南部等中強地震區(qū)。對中強地震區(qū)與橋梁相關的地震問題的這種長期忽略,導致一系列橋梁在防震設計方面存在許多不足之處,為了更長久和有效地使用橋梁,必須對橋梁進行評估和審查。最近,一種新興的決策工具在地震風險評估研究中變得越來越流行,叫做地震易損性曲線。在也門這五種類型的橋梁被定義為:本研究的目的是改進一種有趣的方法,用于研究也門中部和東南部地區(qū)典型橋梁的地震易損性曲線數(shù)據。雖然已有對地震易損曲線的研究,但大多數(shù)都集中在也門西部和敘利亞的高地震帶的橋梁。由于認識到大規(guī)模地震的可能性,現(xiàn)在重心更多放在也門地區(qū)。為幫助評估該地區(qū)的地震危險性,選擇了五種典型的橋梁來研究地震易損性曲線:1-多跨支撐連續(xù)混凝土梁2-多跨支撐連續(xù)鋼梁3-多跨支撐連續(xù)板4-多跨支撐連續(xù)混凝土箱梁5-多跨支護簡支混凝土梁這五種橋梁占該地區(qū)160,000多條高速公路橋梁的近90...
