Reinforced concrete T beam bridge has the following advantages: simple production, Liang Lei within the reinforcement can be made into a rigid framework of steel reinforcement, the beams between the use of multi-channel diaphragm beam connection, good integrity. Its disadvantages are: shape instability, transportation and installation is complex; member just before the bridge span joint on board, poor stress. Therefore, the construction of the bridge deck is often done more narrow. The design for the reinforced concrete T type beam bridge, its lower part structure for gravity type bridge pier and abutment U type, and through the cast-in-place concrete bridge panel are connected into a whole. This chapter will detail of reinforced concrete simply supported T beam design calculation. Key words: type T simple supported beam bridge; advantages; disadvantages; the beam stress calculation; calculation目录摘 要Abstract1 方案比选 11.1 桥梁设计原则 11.2 桥型介绍 12 ...
