以往在设计钢筋混凝土受弯构件时成功地应用了材料图或钢筋弯矩图[1],而在设计偏心受压构件时还没有应用过.因为偏心受压构件的纵向钢筋数量既取决于弯距 M,又取决于纵向力 N。为了合理地设计偏心受压构件.应用了钢筋面积图.即先按强度条件确定构件每个截面所需要的钢筋数量.然后画出计算所需的钢筋 In the past, when designing reinforced concrete bending members, material diagrams or steel bending moment diagrams [1] were successfully applied, but they have not been applied when designing eccentric compression members. Because the number of longitudinal reinforcements of eccentric compression members depends on both From M, it depends on the longitudinal force N. In order to reasonably design the eccentric compression member, the area diagram of the rebar is applied. That is, the number of rebars required for each section of the member is determined first according to the strength condition. Then the rebars required for the calculation are drawn.
