摘要
本文建议在混凝土圆板设计中以中密方格钢筋网代替常用的均匀方格钢筋网,可收到节省钢材12～22％的效果。文中用极限平衡法的上限解法(破坏线理论)推导了该种配筋体系的混凝土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 for reinforcing circular concrete slabs, instead of homogeneous ones commonly used,a nonhomogeneous two-way steel net is proposed, due to which there is a saving of 12～22％ in reinforcing steel. Based for this type of slabs under uniformly distributed loading is obtained. The design approach is also suggested.
