［提要］ 以多道設(shè)防為指導(dǎo)思想,完成了對(duì)青島帆船中心斜拉索廊橋的結(jié)構(gòu)設(shè)計(jì)。利用有限元方法，評(píng)估了預(yù)應(yīng)力拉索對(duì)該結(jié)構(gòu)性能的影響，分析了溫度荷載作用下預(yù)應(yīng)力拉索、結(jié)構(gòu)構(gòu)件的內(nèi)力變化及結(jié)構(gòu)本身支座反力變化的規(guī)律，并根據(jù)數(shù)值分析結(jié)果，進(jìn)行了支座的節(jié)點(diǎn)設(shè)計(jì)。計(jì)算結(jié)果及設(shè)計(jì)內(nèi)容均直接用于指導(dǎo)該工程的具體實(shí)施。

Structure Design of the Prestressed Cableshauled Bridge of Qingdao Sailing Vessel/Zhen Wei, Li Weizheng, Gao Wei(Beijing Institute of Architectural Design, Beijing 100045, China)
Abstract:The design for gallery bridge is accomplished with the guideline of multidefenses. The effect of prestressed cables which has improved the behavior of the structure is estimated through FEM method. The variation of support reactions and the inner forces of structural members and prestressed cables are analyzed when the structure is under temperature load. According to the obtained numerical results, the connections for supports are designed. All the calculated results and design contents have been used to guide the construction of the project.
