变截面受弯构件裂缝控制时承载力简化计算

敞开式水处理构筑物池壁从经济上考虑通常做成变截面 ,其悬壁池壁结构竖向配筋基本上都采用分段配置 ,但确定截断点位置的理论计算较复杂。本文根据变截面受弯构件裂缝控制时钢筋切断位置的技术要求 ,通过拟合法建立计算公式 ,供设计人员参考使用

Simplified Calculation of Carry Capacity Controlled by the Width of Crack about the Bent Structure with Variable Cross-section

In order to be economical,the wall of open type water treatment structure is usually designed to be variable cross section,the vertical reinforcement in these cantilever wall are laid sectionally,but it is difficulty to confirm the point where the bar to be cut through theoretical calculation.According to the structural carrying capacity controlled by the width of crack of the practicality,a simplified calculation method to confirm the cut point is introduced which can provide reference for designers.
