The closure scheme optimization analysis of multiple large-span prestressed continuous beam bridges Jianming Hao1, a, Kaifa Zhou1,b 1School of Civil Engineering and Architecture , Chongqing Jiaotong University , China a123789247@qq.com, bkfzhou@cquc.edu.cn Keywords: multi-span prestressed continuous beam bridges, closure scheme, cantilever construction method, system transformation.
Closure scheme Advantage Disadvantage Engineering example 1 Close multi-span continuous system once ①Internal force changes more uniform ②Shorten construction period ③Avoid the increase of statically indeterminate times, make calculations simple ①Need more constructors and equipment； ②Tensioning closure strands will induce larger secondary internal force.
Take Wei river eight-span continuous beam bridge for engineering instance, this paper analyze the influences of eleven available closure schemes on internal force, stress and displacement of main girder, analysis shows that: 1.Using different closure schemes affect mid-span control section moment slightly in finished stage, the moment value is close to each other, but root section moment values have large differentials.
