在钢筋混凝土矩形截面小偏心受压构件强度计算中,当偏心距 e_0很小时,截面两端钢筋全部受压,在非对称配筋条件下可以将截面两端的配筋 Ag 和 Ag′的面积按一定关系设计,整个截面的换算重心和偏心距为 e_0的轴力 KN 的作用点重合。这样截面的强度计算可按轴心受压状态进行。
In the calculation of the strength of a reinforced concrete rectangular section with small eccentric compression members, when the eccentricity e_0 is small, the steel bars at both ends of the section are subjected to compression. Under the condition of asymmetrical reinforcement, the areas of the reinforcement Ag and Ag′ at both ends of the section can be determined by In a certain relationship design, the point of action of the axial force KN of the entire cross-section center of gravity and the eccentricity e_0 is coincident. This section of the strength calculation can be carried out according to the state of axial compression.
