Abstract: The analysis of cable-stayed bridges is much more complex than that of conventional bridges (such as truss and girder bridges) due to their huge size and complicated nonlinear structural behaviour. Over the years, researchers have proposed different methods and software to model and analyse cable-stayed bridges but each has their own drawbacks. This paper concerns with the comparison of modelling techniques of the cable-stayed bridge in MIDAS Civil and Staad Pro software. The cable-stayed bridge chosen was symmetrical with cables having a semi-fan configuration. The bridge had H-shaped pylon and the span cantilevered 50 metres on both sides. The bridge was analysed for gravity loads and the results obtained from both the software were presented. It was inferred that all analysis cases need to be considered to arrive at most desirable solution and MIDAS civil might be the preferable tool
