豎向荷載作用下內(nèi)力計(jì)算

1、 合計(jì)： 合計(jì)： 63+1.262.5=54 045（36）8.1kN 豎向荷載梁端調(diào)幅系數(shù)為0.8，計(jì)算跨中彎矩，首先計(jì)算調(diào)幅后的梁端彎矩，然后根據(jù)疊加法計(jì)算跨中彎矩。 圖5.6 H軸恒框架恒載彎矩圖，括號(hào)內(nèi)為調(diào)幅后的彎矩() 然后計(jì)算柱的軸力和剪力，首先根據(jù)各梁端彎矩計(jì)算得出對(duì)應(yīng)梁的剪力，然后根據(jù)梁的剪力計(jì)算得出柱的軸力，注意：柱的軸力計(jì)算時(shí)要考慮柱的自重。具體的計(jì)算過(guò)程如下： 層次剪力軸力8-10跨10-11跨8柱10柱V8V10V10=V11N頂N底N頂N底592.8892.8811.69189.84210.22195.01215.38473.6273.629.54332.15352.
