- Abstract:
- Aimed at the regular cracks appeared in skewed reinforced concrete(RC) deck in prestressed concrete (PC) girder bridge, the deck strains of a girder bridge with 46°skew angle were measured, and the mechanical behaviors of typical skewed reinforced concrete deck subjected to vehicle wheel loads were researched. The results show that the deck strains caused by driving vehicle are low, and the concrete cracks are impossible induced by vehicle loads lonely，but cyclic loads of vehicle wheels may create cracks or make the existing cracks wider, longer and visible. The local effects of wheel loads significantly contribute to the total strain response, especially for longer spans and vehicle at midspan of bridge. As a part of composite cross section, the global loading effect of deck depends on the investigated location. The total strain effect subjected to vehicle load increases slightly with skew angle magnitude.
