两种不同混凝土结构设计规范的主要区别

Main differences between design specification for two different concrete structures

《混凝土结构设计规范》(GB50010-2010)于2011年7月1日正式实施。以钢筋混凝土结构为例,介绍了《水工混凝土结构设计规范》(SL191-2008)与《混凝土结构设计规范》(GB50010-2010)在计算公式、材料、一般构造规定和结构构件设计构造规定等方面存在的主要不同。分析了两规范在受压计算公式、受剪计算公式、裂缝宽度计算公式、挠度计算公式、钢筋种类、混凝土等级、环境类别、混凝土保护层厚度、钢筋锚固长度、最小配筋率和构造规定等方面存在的差异。

The 'Code for Design of Concrete Structure'(GB50010-2010) has come into force recently since July 1,2011.This paper introduced the main differences between the 'Design code for hydraulic concrete structures'(GB50010-2010) and the 'Code for design of concrete structures'(GB50010-2010) from calculating formulas,materials,general structural requirements and structural requirements and soon.The differences are analyzed between the two codes on formula of pressure calculation,formula of shear calculation,formula of crack width calculation,formula of deflection calculation,species of steel bar,concrete grade,environment type,concrete cover thickness,bar anchorage length,minimum reinforcement ratio and structural specifications.
