Calculation of Bearing Capacity for Bending of Prestressed Steel Reinforced Concrete Girder

MU Guang-bo,WANG Lian-guang,ZHOU Le(School of Resources & Civil Engineering,Northeastern University,Shenyang 110004,China.)  
Investigates the bearing capacity for bending of prestressed steel reinforced concrete(PSRC) members to which the earlier works were different theoretically and experimentally.Some existing construction procedures relevant to PSRC members are briefly described.According to the sectional shape of PSRC and loading force acting on it,the main failure modes and the range of height of compressed region in the sectional area of concrete under limit load are analyzed.The formulae of bearing capacity for bending in different failure modes are thus given,where the neutral axis is passing through the web plate of a PSRC girder. A comparison showed that the values of calculation and experiment coincide well with each other.
