| 摘 要： | 介绍新旧《混凝土结构设计规范》的差别,就结构裂缝计算而言,二者的差异主要体现在荷载组合、acr取值两个方面.以合肥市轨道交通1号线葛大店站为例进行定量分析,得出结果:采用新规范,计算结构内力最大可减小12.1％,构件配筋可节约10％～15.4％,造价可减少120万元.

| Abstract: | The paper introduces the differences between the new and the old Code for Design of Concrete Structures.The main differences in structural cracks calculation are load combination and the coefficient "acr".The Gedadian Station on Hefei Metro Line 1 was taken as an example for quantitative analysis.Results showed that the maximum structural internal forces calculated by the new Code can be reduced by 12.1%,that the steel reinforcement can be saved 10%~15.4%,and that the cost saving will be 1.2 million Yuan. |
