本文建议在圆板设计中采用径环向钢筋网代替常用的均匀方格钢筋网,可收到减小板的挠度和裂缝宽度以及节省钢材约15%的效果。文中用极限平衡法(破坏线理论)推导了该种配筋体系的圆板在均布荷载下的极限承载能力计算公式,并提出了实用的设计建议。
In this paper, it is proposed to replace the commonly used uniform grid reinforcement meshes with circular ring reinforcement meshes in the circular plate design, which can receive the effect of reducing deflection and crack width of the plates and saving about 15% of the steel. In this paper, the limit equilibrium method (destruction line theory) is used to derive the formula for the ultimate bearing capacity of circular plates with uniform reinforcement under uniform load, and a practical design proposal is proposed.
