Design Comparison on Birdshape Plates of the New and Old Codes/Cheng Yu,Zhou Suiping,Cheng Yongcai(Sichuan Yanxing Building Construction Technology Co., Ltd.,Chengdu 610041,China)
Abstract:The design results of the birdshape 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 strengt
h in the end part of the members,the reinforcing bar needs to be increased according to the new code.
