| Abstract: | Based on Timoshenko's beam theory, an element of structure is adopted by using a composite concrete and prestressed steel layer system. The computational method for nonlinear analysis of prestressed concrete continuous beams is established and programmed. The load and deformation of seven two-span continuous beams are computed with this program, and the theoretical results show close agreement with the experimental results. |
| Keywords: | prestressed concrete continuous beams finite element nonlinear ultimate strength |
