砼受弯构件满足裂缝限值的配筋计算——程序“ASC”介绍

To Calclate the Reinforcement fitting for crack limit of the Concrete Bending Component ——Recommending the Program"ASC

“允许出现裂缝的构件 ,最大裂缝宽度……计算值不应超过允许值”,这已纳入砼结构设计规范的“强制性条文”。本文作者编制了“ASC”程序 ,可直接分别计算出满足强度条件和限制裂缝宽度要求所需的钢筋截面积 As和 Ascr,以及相应的钢筋直径 ;还可以通过人机对话 ,用不同的钢筋直径反复验算 ,使 Ascr和 As接近 ,达到优化配筋的目的。本文详细介绍了程序的编制原理和使用方法 ,供结构设计人员参考。

The program'ASC'written by the author can calculate two reinforcement area and diameter separately,one is AS which satisfied the intensity condition,the other is ASCR which satisfied the crack width limit .It can also check computation repeatedly with different diameter by man machine conversation to optimize the reinforcement.In this paper,the principle and using of the program are introduced detailedly.
