钢-混凝土组合结构连续梁内力调整技术

针对目前抗震规范无法满足大跨度斜拉桥抗震设计的问题,以上海长江大桥工程为背景,阐述工程的抗震设防标准及性能目标,并通过地震动参数和主辅通航孔桥的抗震性能研究,形成基于结构(或构件)寿命与性能和构件能力保护的抗震设计方法,以保证上海长江大桥工程抗震安全性,为日后大跨度斜拉桥抗震设计提供技术参考.

Techniques of Internal Force Adjustment for Steel and Concrete Composite Continuous Girders

In the light of the problem that the current standards for seismic design can not satisfy the seismic design of long span cable-stayed bridges and in regard of Shanghai Changjiang River Bridge,the seismic fortification criteria and seismic behavior goal of the bridges are illustrated and further through the research of the seismic ground motion parameters and seismic behavior of the main and auxiliary shipping channel bridges of the Shanghai Changjiang River Bridge,a seismic design method based on the life ...
