The Same Number Of Spans Continuous Prestressed Concrete Simply Supported Beam Structure Comparison Of Force

In bridge construction， the result of simply supported prestressed spancontinuous structure，etc. can be used generally，batch prefabricated，so that theconstruction is convenient， while ensuring the continuity of the outstandingadvantages of the bridge. Simply supported prestressed continuous structure hasbecome the majority of highway construction in favor of a popular construction unitstructure type.For porous，such as simply supported prestressed concrete continuous beambridge structure，because its structure is simple，widely used， makes it increasinglyignored for this type of bridge structure internal forces targeted research.Paper through the finite element software Midas Civil software as a platform tobuild4×20m，5×20m，6×20m span simply supported continuous beam structuralmodel，the number of continuous beams of different cross-lasting condition ultimatelimit state，lasting health is normal limit state force calculation.According to the results，summarized across several different transfer prestressedconcrete continuous beam structure in a persistent condition ultimate limit state，long-lasting condition limit state under the law of internal force distributioncharacteristics. And comprehensive analysis of the conclusions of the above analysis，in accordance with the project cost savings，facilitate construction，durable applicableprinciples derived simply supported prestressed concrete continuous structureoptimum design calculation methods.
