摘要：
Pre-stressed concrete (PC) box-girder bridges are statically indeterminate structure in vertical and horizontal direction. In the cross section, forces on top flange, web and bottom flange are interactive. The spatial effects are obvious and the computed stress values based on the plane FE (finite element) are different from the actual stress. Hence, the PC combined elements with the concrete simulated by the layered degenerated shell elements and the pre-stressed steel simulated by the link elements are presented and element stiffness matrix have been deduced. A typical PC box-girder bridge w...
