2、風(fēng)荷載驗(yàn)算 1) 模板支架風(fēng)荷載標(biāo)準(zhǔn)值計(jì)算 la=0.75m，h=1.8m，查《規(guī)程》表4.2.7得φw=0.166 因風(fēng)荷載沿模板支架橫向作用，所以b=la=0.75m，b/h=0.75/1.8=0.417 通過插入法求η，得η=0.95 μzω0d2=1.77×0.5×0.0482=0.002，h/d=1.8/0.048=37.5 通過插入法求μs1，得μs1=1.198 因此μstw=φwμs1(1-ηn)/( 1-η)=0.166×1.198×(1-0.9570)/(1-0.95)=3.868 μs=φwμstw=0.166×3.868=0.642 ωk=0.7μzμsω0=0.7×1.77×0.642×0.5=0.398kN/m2 2) 整體側(cè)向力標(biāo)準(zhǔn)值計(jì)算 ωk=0.7μzμsω0=0.7×1.77×1×0.5=0.62kN/m20.166×3.868=0.642 ωk=0.7μzμsω0=0.7×1.77×0.642×0.5=0.398kN/m2 2) 整體側(cè)向力標(biāo)準(zhǔn)值計(jì)算 ωk=0.7μzμsω0=0.7×1.77×1×0.5=0.62kN/m21、查《規(guī)程》表4.2.7得φw=0.166？表中最小縱距為1.2m，這個(gè)φw=0.166如何計(jì)算出來的2、通過插入法求η，得η=0.9...閱讀全文
