| Abstract: | Some simplified methods for the elastic and clasto-plastical analysis of prestressed compostie steel-concrete girders with different scqucnce of prestressing, different construction methods, and with classll sections, were studyed in this paper. Equations were provided for the calculation of the yield or cracking load and ultimate capacity of the girders. The cal culation results were good with the test results. These methods can be used as a reference for the designing and results construction. |
