摘要
本文提出了新《混凝土结构设计规范》小偏心受压构件的纵向钢筋简化计算方法。对现行规范(TJ10—74)小偏心受压构件受压区混凝土合力D对A(?)合力点的力矩定值表达式,根据试验进行了修正,提出了纵向钢筋计算方法。同时给出了算例及图表,与精确计算相比,有一定精度,计算简便。
This paper presents a new simplified calculating method for concrete stnc-ture desing code to determinc the area of longitudinal bars in cempressive membersioad. ed with small eccentricities.Based on the tests,the expression of constant moment of resultant force D with respect lo. point As in the comprcssivc region of concrete members with small eccentricity in code (TJ10-74) is revised and a calculating method for the-longitudinal bars is presented in this paper. At the same timc,somc examples and charts are given,It indicates that there is a certain precision comparing with the accurate rcsults.Apparently this method is simpler and more convenient.
