Prestressed Concrete Continuous Beam Bridge Span Arrangement and Structure Size Proposed Analytical

Abstract

By analyzing the bridge structure in the course of the dead load and live load, taking into account different load safety factor for load combinations that will limit state as a result of the combination of two kinds of forces calculated tendon force estimates, estimate the various sections of the steel beam, in accordance with certain requirements of the steel beam is a good layout, construction and consider re-simulate prestress for the role of the second combination, the process of the construction and use of a cross-sectional strength checking, stress and deformation checking checking.
