六層框架樓的內力組合形式.doc

內力組合 各種荷載情況下的框架內力求得后，根據最不利又是可能的原則進行內力組合。當考慮結構塑性內力重分布的有利影響時，應在內力組合之前對豎向荷載作用下的內力進行調幅。其中在恒載作用下，對梁端負彎矩進行調幅，調幅系數為0.8，而且當梁端負彎矩減小后，應按平衡條件計算調幅后的跨中彎矩，調整后梁跨中正彎矩至少應取按簡支梁計算的跨中彎矩的一半，即。在活載作用下，采用滿跨布置荷載的方法，對梁端負彎矩進行調幅，調幅系數也為0.8，而且當梁端負彎矩減小后，應按平衡條件計算調幅后的跨中彎矩。但在滿跨布置荷載時，求得的梁的跨中彎矩比最不利荷載位置法的計算結果要小，因此對跨中彎矩應乘以1.2的系數予以增大。調整后梁跨中正彎矩至少應取按簡支梁計算的跨中彎矩的一半，即。分別考慮恒荷載和活荷載有可變荷載效應控制的組合和由永久荷載效應控制的組合，并比較兩種組合的內力，取最不利者。由于構件控制截面的內力值應取自支座邊緣處，為此，進行組合前，應先計算各控制截面處的（支座邊緣處的）內力值。梁支座邊緣處的內力值： 式中 -支座邊緣截面的彎矩標準值； -支座邊緣截面的剪力標準值； -梁柱中線交點處的彎矩標準值； - 與相應的梁柱中線交點處的剪力標準值； -梁單位長度的均布荷載標準值； -梁端支座寬度（即柱截面高度）。 柱上端控制截面在上層的梁底，柱下端控制截面在下層梁頂。按軸線計算簡圖算得的柱端內力值，宜換算到控制截面處的值。1表 1 恒載作用下梁端彎矩調幅和調幅后剪力計算（調幅系數0.8）
