Static Analysis Of Total Structure Of Minpu Bridge â…¡ In Shanghai

Cable-stayed bridge was less for rail traffic areas, with the rapid development of economy, therail transit bridge construction has been in great demand and urgent need of large span structure. Thecable-stayed bridge reflects the tremendous potential in urban rail transit bridge development in thiscase. how to ensure that these bridge in safe working condition, has become an important researchtopic.This paper takes Minpu Bridge II as the research background,and uses large finite elementsoftware MIDAS built a finite element model of the bridge as a whole. The force and deformationunder dead load, live load,,local temperature, wind load and other load are calculated in theoperational phase. The bearing capacity of bridge structure is verified.The cable-girder anchorage zone of stay cable is the key to control design due to structurecomplex and force concentration, to master the stress value and its distribution is important. The FEmodel of the cable-girder anchorage zone for Minpu Bridge II is founded, Based on equivalent platethickness method, its stress distribution is analysed.Through the full-bridge analysis for long-span steel truss cable-stayed bridge,under the condition of different structure can satisfy the requirements of strength and rigidity, the struc-tural behaviors of the bridge is summed up, which may be some references to the design andconstruction of similar-type bridges in future.
