简介偏心受压钢筋混凝土构件在工程中应用较广,如柱子、屋架上弦、有垂直荷载的挡土墙、高层建筑中的剪力墙正截面强度计算等均按偏心受压构件计算。对于对称配筋的钢筋混凝土柱,较多采用苏联的曲线表计算,即纵、横座标表示N、ηM,在曲线中找出A_g或A_g~′值。此方法优点是辅助运算少,缺点是精度低、一个截面尺寸占一张图 Introduction Eccentrically pressed reinforced concrete components are widely used in engineering. For example, column, truss chord, retaining wall with vertical load, shear wall strength calculation in high-rise buildings are calculated according to eccentric compression members. For reinforced concrete columns with symmetrical reinforcement, the curve tables of the Soviet Union are more commonly used, that is, vertical and horizontal coordinates indicate N and ηM, and A_g or A_g~’ values ​​are found in the curves. The advantage of this method is that there are few auxiliary operations, and the disadvantage is that the accuracy is low and a cross-sectional size accounts for one figure.
