| Abstract: |
Prestressed concrete continuous rigid frame bridge is one of the main types of long-span bridges due to its mature construction technology and low cost during construction and operation. The corresponding design theory and construction technology were focused on the control and prevention technology of cracking and deflection. Based on an actual bridge inspection, obvious connected effect of separated structures was found that additional deformation and stress increase of the amplitude structure induced by the influence of the central transverse connection (diaphragm, central guardrail consolidation base, etc. ) can not be ignored. Suggestions including raising safety coefficient or adopting refined analysis model are provided. |
