TJ 10 a 74 standard bending and compression (including the size of eccentric compression) bearing capacity of the formula is basically based on the analysis of test results established. For complex situations (such as abdominal reinforcement, two-way bending, two-way compression and arbitrary cross-section), can not be extrapolated. GBJ-89 specification, by introducing the assumption of plane section, and gives the ideal of steel and concrete stress-strain curve, the section of the regular case of the shape and form of reinforcement is given a simplified practical formula, given by the level The cross-section is assumed to determine the boundary conditions of the super-reinforcement and the large and small eccentric compression of the flexural members. The calculation of normal section bearing capacity of reinforced concrete members is assumed to be based on the scientific system.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery
In addition, the GBJ10-89 specification modified the calculation method of the long column eccentricity increase coefficient based on the cross-sectional limit curvature of the TJ10-74 specification, and increased the stress of the steel wire in the prestressed concrete flexural members considering the configuration of high-strength steel wire Into the enhanced section of the bearing capacity of the positive section to improve the calculation formula, which can save steel.
