Study of Earthquake Loading On the Analysis of Cable Bridge Structure Using Staad Pro

Abstract

To overcome the obstacles like crossing of river, Dam, Heavy Traffic flow in the way of journey Bridges were the part of our day-today life. Construction of such kinds of Bridges were being much challenging. Construction of bridge works are making the life complicated. Much efficient and quick construction of bridges are very important. Cable stayed bridges are visualized for their less construction time, Higher Efficiency. In the construction aspect cable stayed bridges have less supporting points to the ground when compared with traditional Bridges. By thus it is having higher sensitivity to natural calamities like Seismic activity like Earthquakes. Because of supporting long length by pylons the response of these kind of structures should be analyzed for safe construction and better serviceability. The complicated analysis procedure makes the structure safer. The complicated analysis can be simplified by the software’s like Staad Pro. In the software we can create earthquakes in various intensities and the real-time response can be found out. This paper describes more about the cable bridges and their response for the Seismic activity. The analysis procedure is done in Staad Pro and the response of a model cable stayed bridge is figured out for gaining the safety standards for safer construction of Cable Stayed Bridge.
