Finite Element Analysis of C Able Stayed Bridge with Different Arrangement of Cables

The Cable Stayed Bridge is one of the modern bridges which were built for the longer spans and for better enhancement of the work in the field of aesthetic appearance and durability, therefore there is a need of study which overcomes the idea about the different possibilities in the structural arrangement in the terms of economy and aesthetical appearance. This study reveals an idea about the behaviour of the different arrangement of cables in the linear dynamic analysis of Cable Stayed Bridges under seismic load. The modelling and analysis of bridge has been carried out using SAP 2000 with vehicular interaction as per IRC & the effects of earthquake as per IS 1893: 2016 for Zone V. For the modelling of bridges, the arrangement of self anchored cable stays has been considered as semi fan type, fan type and harp type with the constant dimensions of height of pylon and span of bridge. From these results, the behaviour of the different arrangements of cables used in cable stayed bridge has been easily determined in the assumed appropriate conditions.
