雁形板按新旧规范计算的比较

Design Comparison on Bird-shape Plates of the New and Old Codes

分别按新、旧混凝土设计规范对雁形板进行设计。设计结果比较表明:在抗弯承载力、裂缝控制及挠度计算方面,雁形板按新、旧规范设计结果差别极小,但在抗剪承载力及雁形板端部的各项局部强度计算中,按新规范要求的用钢量有所增加。

The design results of the bird-shape plates according to the new and old codes for design of concrete structure are compared respectively. The comparison shows that the diffrences between the both design results in the bending strength, crack and deflection control of the bird-shape plates are very small. While for the shear strength and local strength in the end part of the members, the reinforcing bar needs to be increased according to the new code.
