【判断题】
一矩形截面混凝土柱,b×h = 400×500mm,ea = 20mm,承受轴向压力设计值N = 1357.0kN,杆端弯矩设计值M1 = M2 = 362.0kN•m,Cm = 1,lc = 6m,ns = 1.178,as = a’s = 40mm,混凝土采用C35(fc = 16.7N/mm2,ft = 1.57N/mm2,1 = 1.0),纵向钢筋采用HRB400级(fy = f’y = 360N/mm2,b = 0.518,一侧’min = 0.2%,全部allmin = 0.55%),试求该柱采用非对称配筋时所需的纵向钢筋截面面积As
及As′
(不必配筋,不必验算轴心受压承载力)。( )
