摘　　要：依据新颁布的《混凝土结构设计规范》GB50010—2010中裂缝宽度计算公式,对一类环境下不同配筋方案的钢筋混凝土梁、板,从强度条件和裂缝控制两方面进行了计算分析。结果表明,一类环境下的梁,采用HRB400钢筋,可充分发挥其作用;板类构件,采用HRB500钢筋,可充分发挥其作用。According to the newly promulgated formula of crack width in the Code for Design of Concrete Structures(GB50010-2010),Both strength condition and the cracking-control of different reinforcement programs of reinforced concrete beam and slab were calculated and analyzed within the first-class environment.The HRB400 reinforcing bar is suitable for beam and HRB500 for slab.

关 键 词：HRB400钢筋 HRB500钢筋 裂缝宽度 受弯构件
