| Abstract: | The construction simulation of the prestressed steel-concrete composite beams is demonstrated by using the element death and alive function of FEM.And the approximation of prestressed load is achieved by adopting the dichotomy.The numerical result indicates the method is successful.It provides an efficient computer aided analysis method for the prestressed load design and construction of the prestressed steel-concrete composite beams. |
