Abstract: In this paper influence of structural nonlinearities on internal force of super-long span Cable-Stayede Llnder service stage is studied .3he cable sag efect,the beam-columnefect and the a displacement effect are taken into accountinthe study.Based on the study of a cable-stayed bridge with a main spai of meter than lO00-meter-long .the nolinear influence factors of internal force at controlling sections are evaluated .Finally,the measlles to reduce the influence of nonlineafiles presented

Key words: nonlinearity, super-long span, cable-stayed bridges, internal force under service stage

摘要: 笔者研究了非线性因素对超大跨度斜拉桥使用阶段内力的影响,分析中同时考虑了拉索垂度效应、P一△效 应和大位移效应的影响。以一座主跨超千米的斜拉桥为例,给出了各控制截面内力的非线性影响系数,并提出了减 小超大跨度斜拉桥非线性影响的措施
