钢筋混凝土小偏心受压构件的计算方法探讨

Study on the Methods of Calculating the Strength of Compressed Reinforced Concrete Members with Small Eccentricities

对钢筋混凝土非对称配筋小偏心受压构件的强度计算方法进行了分析和讨论，证明了按Ａｓ＝ρｍｉｎｂｈｏ确定ξ值进行截面配筋计算是最优设计方案，并指出在截面设计时按全截面受压的假定进行计算是不合理的。

The methods of calculating the strength of compressed reinforced concretemembers with small eccentricities are analyzed and discussed in this paper. It is proved thatthe design method of calculating the relative depth of neutral axis ξbased on As =ρminbho ismost reasonable and pointed that the assumptions of the compression produced over thesection in design don’t conform with the real situation in most cases.
