- This paper presents the performance of a cable-stayed bridge by representing a model using the ANSYS program under the influence of a concentrated load and then comparing the results with the experimental results. One model used in the analysis was the Harp type 1, which used the length of the girder (4500mm), the height of the pylon (1480mm), and the depth of the flange on the girder (40mm). If cable-stayed bridges are constructed using the balanced cantilever method, the stability problem of the girder is more significant during the construction stage than at the initial state. In this study, to investigate the ultimate behavior of cable-stayed bridges, experimental and analytical studies were conducted for one model: Harp Type 1. At the limit state, several plastic hinges occurred, and the girders buckle along the entire span. Numerical analysis was conducted for the experimental model, the results of which showed good agreement with the experimental results. The influence of such effects on the analysis and the structural role of cable-stayed bridges has been detailed and examined in the study. The dimensions of the model were also compared with the ICE Code in terms of the height of the tower to the main space, and the back span to the main span ratio. It was close to standard specifications. A finite element procedure for the nonlinear analysis of cable-stayed bridges first set up and then detailed for the static deflection analysis of such bridges is carried out.
