(四)裂缝宽度验算原规范的裂缝宽度计算公式是建立在以钢筋粘接滑移为主的平均裂缝宽度基础上,即裂缝的开展是由于混凝土的回缩造成,其计算公式是通过试验校正确定。计算最大裂缝宽度的基本公式为:
(IV) Crack Width Check The original crack width calculation formula is based on the average crack width based on the bond-slip of the steel bars. That is, the cracks are caused by the shrinkage of the concrete. The calculation formula is corrected by tests. determine. The basic formula for calculating the maximum crack width is:
