sectional area of reinforcement的意思|示意

The cross sectional area of the distributing concrete every unit length should be not suitable less than 35% of the ratio of reinforcement;

单位长度上分布钢筋的截面面积不宜小于单位宽度上受力钢筋截面面积的35％；

The maximum loss ratio of sectional area is used, instead of the loss ratio in weight, to express the mechanical properties of corroded reinforcement.

为了揭示锈蚀钢筋力学性能退化现象的本质，用锈后钢筋的最大截面损失率来表征其力学性能的变化。
