自锚式斜拉-悬索协作体系桥静风响应分析

自锚式斜拉-悬索协作体系桥作为一种全新的结构体系，兼备了自锚式悬索桥和斜拉桥的许多优点，结构体系则更为复杂。结合400m主跨的金州海湾大桥这一实际工程方案，建立了有限元空间分析模型，分析了其在静风荷载作用下的非线性行为，总结了初始攻角、附加攻角等参数及是否考虑缆索系统承受风荷载等对体系的影响规律。

Analysis of Static Wind Response to Coordinated System Bridge of Self - Anchored Cable - Staying and Suspension

As a wholly new structure system,the coordinated system bridge of self- anchored cable - staying and suspension has merits of both self-anchored suspension and cable stayed bridges,its structure system is more eomplex. In the light of schemes for Jinzhouhaiwan bridge engineering with 400m main span,the paper establishes the model for finite element space, analysis analyzes its nonlinear behavior under static wind load and sums up the law of influence of parameters of initial and additional angles of attack as well as cable system - borne wind load on the system.
