【摘要】 本文以吉林市临江门斜拉桥为例,应用固体力学的有限元理论,考虑荷载组合效应的影响,采用国内比较先进的Sap93程序进行整体结构分析。得出主梁、缆索、塔架以及其它承载结构的最大内力和最大位移。为斜拉桥的养护和维修提供必要的参数依据。更多还原

【Abstract】 Taking Linjiangmen Bridge in Jilin City as the example, the authors of this paper analyzed the concrete over-all stayed-cable bridge with the considerations of load combination on the bridge. The results such as the maximum stress and the maximum bit shifts of the king piece, cable, tower and other load bearing parts, which can be used as the important references for the maintenance of the bridge were obtained by using finite element method and Sap93 Program.更多还原
