题目:

某五层现浇钢筋混凝土框架结构多层办公楼,安全等级为二级,框架抗震等级为二级,其局部平面布置图与计算简图如下图所示。框架柱截面尺寸均为b×h=450mm×600mm;框架梁截面尺寸均为b×h=300mm×550mm,其自重为4.5kN/m;次梁截面尺寸均为b×h=200mm×450mm,其自重为3.5kN/m;混凝土强度等级均为C30,梁、柱纵向钢筋采用HRB335级钢筋,梁、柱箍筋采用HPB300级钢筋。2~5层楼面永久荷载标准值为5.5kN/m2,可变荷载标准值为2.5kN/m2;屋面永久荷载标准值为6.5kN/m2,可变荷载标准值为0.5kN/m2;除屋面梁外,其他各层框架梁上均作用有均布永久线荷载,其标准值为6.0kN/m。在计算以下各题时均不考虑梁、柱的尺寸效应影响,楼面永久荷载标准值已包括板自重、粉刷及吊顶等。说明:已按最新规范将本题“箍筋采用HPB235级钢筋”改成“HPB300级”。

试问,在计算简图18.000m标高处,次梁L1作用在主梁KL1上的集中荷载设计值F(kN),应与下列何项数值最为接近?()提示:①当板长边/板短边>2时,按单向板推导荷载;②次梁L1在中间支座处的剪力系数为0.625。

A.211

B.224

C.256

D.268
