Behavior of Asymmetric Cable Stayed Bridge for Long Span

Abstract

In the recent years cable stayed bridges have received more attention than any other bridges. As one of the most competitive bridge in modern times, the cable stayed bridge is ideally suitable for long span. Asymmetric cable stayed bridges are the upgrade of conventional cable stayed bridges. Analytical investigation is an important in the study of asymmetric cable stayed bridge. The response of the bridge deck under moving traffic load is very important in the analysis process. Even the slightest deflection may result in the collapse of the bridge structure. Recent reports states that the cable stayed bridges are subjected to wave like vibrations when subjected to moving loads. So the bridge must be analyzed in such a way that its deflections are well under the permissible limits. The parameters like displacements, shear forces, bending moments and percentage of reinforcements were studied in long span asymmetric cable stayed bridge. The asymmetric cable bridge was modeled using SAP2000 software.
