,xxx無梁樓板計(jì)算書,,,,,,

,(等代框架法),,,,,,

一、總信息:,,,,,,,

,,,,,,,,

,混凝土強(qiáng)度,C30,板跨(X向),4.000,(m),,

,鋼筋強(qiáng)度,HRB335,板帶寬(Y向),5.000,(m),,

,荷載方式,均布荷載,板厚,300,(mm),,

,裂縫限值,0.2mm,板面活載,40,(kN/m2),,

,,,板面恒載,0,(kN/m2),,

,,,,,,,,

二、荷載計(jì)算:,,,,,,,

,1、恒載:gk=0.3*25+0=7.5kN/m2,,,,,,

,活載:p=40kN/m2,,,,,,

,,,,,,,,

,2、板面荷載標(biāo)準(zhǔn)值:,,qk=7.5+40=47.5kN/m2,,,,

,設(shè)計(jì)值:,,q=1.2*7.5+1.3*40=61kN/m2,,,,61

,,,,,,,,

,3、柱帽承受集中軸向壓力標(biāo)準(zhǔn)值:,,Nk=47.5*4*5=950kN,,,,

,設(shè)計(jì)值:,,N=61*4*5=1220kN,,,,

,,,,,,,,

三、板抗沖切計(jì)算:,,,,,,,

,取中柱計(jì)算,柱帽尺寸為1200x1200mm,h0=300-45=255mm,,,,,,,

,,0.7βh*ft*η*μm*h0,=0.7*1*1.43*0.939*5820*255,,,,

,,,=1393.69kN,>N,,,

,,故板抗沖切計(jì)算,滿足!,,,,
