苏拉马都大桥引桥抗震分析

苏拉马都大桥是印度尼西哑的一座特大型桥梁,其引桥为预应力混凝土连续箱梁结构,通过V形墩与主桥相连.由于桥址处抗震设防烈度较高,又是跨越马都拉海峡的特大型桥梁,其抗震性能尤为重要.采用两水平的抗震设计方法,从地震输入、地震反应谱分析、非线性时程分析、结构的抗震性能验算等方面对苏拉马都大桥引桥的抗震性能进行分析,结果表明,...

Earthquake Response Analysis of Approach Bridge of Suramadu Sea-Crossing Bridge

Surammadu Bridge is an especially large bridge in Indonesia.Its structure style is pre-stressed concrete continuous box bridge and links with the main bridge by V-style pier.The seismic performance of Suramadu Bridge is particularly important because of the bridge across the Madula Strait and the high seismic intensity at the bridge site.In this paper,based on the antiseismic design of Suramadu Approach Bridge,seismic behavior of cable-stayed bridge is investigated by two-level earthquake-resistance method ...
