安全性鉴定中混凝土梁构件的钢筋面积比和抗力效应比分析

Analysis of Reinforcement Area Ratio and Resistance Effect Ratio of Concrete Beam Components in Safety Appraisal

文章采用控制变量法对安全性鉴定中混凝土梁构件的钢筋面积比和抗力效应比进行了比较。研究数据表明:采用钢筋面积比评定混凝土梁构件的承载能力安全性等级是不正确的方法,钢筋面积比不等于抗力效应比;应通过实配钢筋计算抗力,采用抗力效应比正确评定混凝土梁构件的承载能力安全性等级。

This article compares the steel reinforcement area ratio and resistance effect ratio of concrete beam components in safety assessment using the controlled variable method.Research data shows that using the steel reinforcement area ratio to evaluate the safety level of the bearing capacity of concrete beam components is an incorrect method,as the steel reinforcement area ratio does not equal the resistance effect ratio;The resistance should be calculated through actual reinforcement,and the safety level of the bearing capacity of concrete beam components should be correctly evaluated using the resistance effect ratio.
