沈阳市富民桥主塔应力状态研究

Study of Stress Conditions of Pylons of Fumin Bridge in Shenyang

沈阳市富民桥主桥为国内首次采用的折线形双塔独柱式单索面斜拉桥,重点阐述斜拉桥折线形主塔的结构受力特性以及设计索力的布置规律,同时针对塔身混凝土应力敏感部位进行局部分析,提出改进措施。

The main bridge of Fumin Bridge in Shenyang is the first cable-stayed bridge designed with double kinked column pylons and single cable plane in China. In this paper, the structural stress behavior of the kinked pylons and arrangement pattern of the designed cable forces are mainly dealt with, and meanwhile, the local analysis of the concrete stress in the sensitive areas of the pylons is conducted, and the improvement measures for the stress conditions are proposed as well.
