The observed damages in carrying deck of RC bridge over the Wieprz River in Baranow indicate that over pillar zones are not protected enough. The results of numerical analysis have shown that tensile stress in T- section beam appears not only in a web but in flanges as well. Thus reinforcing bars should be distributed within the whole effective width. This fact is mentioned in building codes, for example, in Eurocode 2: "Design of concrete structures", both in part 1.1 "General rules and rules for building" and in part 2 "Reinforced and prestressed concrete bridges", but there are not detailed rules how to place the bars in flanges of T-section.展开更多
文摘In this paper the analysis of tensile stress distribution in flexural continuous T- beam has been presented. The observed damages in carrying deck of RC bridge over the Wieprz River in Baranow indicate that over pillar zones are not protected enough. The results of numerical analysis have shown that tensile stress in T- section beam appears not only in a web but in flanges as well. Thus reinforcing bars should be distributed within the whole effective width. This fact is mentioned in building codes, for example, in Eurocode 2: "Design of concrete structures", both in part 1.1 "General rules and rules for building" and in part 2 "Reinforced and prestressed concrete bridges", but there are not detailed rules how to place the bars in flanges of T-section.
