| Abstract | ||||
| The concept of prestressing steel structures has only recently been widely considered, despite a long and successful history of prestressing concrete members. The configuration of the beam affects the straining actions and deformations of the prestressed steel beams. In this research, the behavior of the prestressed steel beams is illustrated using fmite element analysis. The dimensions of the beam have been changed to fmd out their effect. The existence of vertical stiffeners has been also studied to fmd out its influence on prestressed steel beams compared with non-prestressed beams. This study has been catried out under the same static loads. The results show that it is better to increase the flange width to improve the stiffness of the prestressed beams while it is better to increase the web depth to improve the stifhess of the nonprestressed beams. It has been also noticed that there is not any obvious benefits of using vertical stiffeners | ||||
