9 多層鋼筋混凝土框架內(nèi)力組合畢業(yè)論文.doc

東南大學(xué)畢業(yè)設(shè)計(jì)-62-九內(nèi)力組合本章中單位統(tǒng)一為：彎矩kNm，剪力kN，軸力kN。根據(jù)前面第四至八章的內(nèi)力計(jì)算結(jié)果，即可進(jìn)行框架各梁柱各控制截面上的內(nèi)力組合，其中梁的控制截面為梁端柱邊及跨中，由于對(duì)稱性，每層梁取5個(gè)控制截面。柱分為邊柱和中柱，每根柱有2個(gè)控制截面。內(nèi)力組合使用的控制截面標(biāo)于下圖。（一）梁內(nèi)力組合1計(jì)算過程見下頁表中，彎矩以下部受拉為正，剪力以沿截面順時(shí)針為正注：（1）地震作用效應(yīng)與重力荷載代表值的組合表達(dá)式為：EhGE3S.12S.1S其中，SGE為相應(yīng)于水平地震作用下重力荷載代表值效應(yīng)的標(biāo)準(zhǔn)值。而重力荷載代表值表達(dá)式為：n1iikQikQGGGk恒荷載標(biāo)準(zhǔn)值；Qik第i個(gè)可變荷載標(biāo)準(zhǔn)值；Qi第i個(gè)可變荷載的組合之系數(shù)，屋面活荷載不計(jì)入，雪荷載和樓面活荷載均為0.5?？紤]到地震有左震和右震兩種情況，而在前面第八章計(jì)算地震作用內(nèi)力時(shí)計(jì)算的是左震作用時(shí)的內(nèi)力，則在下表中有1.2(+0.5)+1.3和1.2(+0.5)-1.3兩列，分別代表左震和右震參與組合。（2）因?yàn)轱L(fēng)荷載效應(yīng)同地震作用效應(yīng)相比較小，不起控制作用，則在下列組合中風(fēng)荷載內(nèi)力未參與，僅考慮分別由恒荷載和活荷載控制的兩種組合，即1.35+1.40.7和1.2+1.4兩列。ABCD123452211東南大學(xué)畢業(yè)設(shè)計(jì)-63-梁內(nèi)力組合計(jì)算表樓層截面恒荷載活荷載(屋面布雪載)活荷載(屋面布活載)風(fēng)荷載(左風(fēng))MVMMVVMV五1-32.5860.19-4.466.08-1.516.41-9.5119.36275.537.431.1130.073-46.9-65.37-5.53-3.86-1.51-6.81-14.72-21.234-21.8213.55-2.143.49-2.911.41-7.634.325-14.23-1.40-4.46四1-76.42118.02-13.615.75-4.1119.76-14.819.832125.8925.442.1823.883-88.81-122.5-16.58-11.39-4.11-20.83-17.39-20.764-26.7614.02-5.4510.22-8.515.41-5.055.415-20.17-2.660-2.2三1-77.56118.07-14.1925.57-6.5519.76-14.1919.762124.5224.673.9524.673-89.64-122.45-16.98-17.68-6.55-20.8-16.98-20.84-26.2314.02-5.2515.9-13.255.41-5.255.415-19.61-2.430-2.43二1-77.67118.11-14.2135.14-9.2219.8-14.2119.82124.5224.674.7324.673-89.53-122.41-16.97-25.69-9.22-20.79-16.97-20.794-26.2814.02-5.2623.02-19.185.41-5.265.415-19.67-2.440-2.44一1-71.44117.77-13.1152.76-13.7419.83-13.1119.832130.7424.667.7724.663-81.37-121.39-15.54-37.22-13.74-20.7-15.54-20.74-27.5513.84-5.433.03-28.115.37-5.45.375-21.32-2.750-2.75東南大學(xué)畢業(yè)設(shè)計(jì)-64-梁內(nèi)力組合計(jì)算表（續(xù)）樓層截面地震作用(左震)1.2(+0.5)+1.31.2(+0.5)-1.3MVMVMV五141.86-10.3712.6562.59-96.1989.5627.65105.0485.153-26.57-10.37-94.14-96.01-25.06-69.05424.01-203.75-8.89-58.6843.1150-17.92-17.92四196.48-25.3825.56120.49-225.29186.47212.74182.89149.773-71.01-25.38-208.83-192.49-24.21-126.50463.61-53.0147.31-48.84-118.0888.9850-25.80-25.80三1159.63-40.7105.93100.63-309.11206.45225.32197.14131.313-109-40.7-259.46-212.3323.94-106.51498.06-81.7292.85-86.17-162.10126.3150-24.99-24.99二1193.69-50.89150.0787.46-353.53219.77225.76197.71130.743-142.17-50.89-302.44-225.5267.20-93.214127.36-106.13130.88-117.90-200.26158.0450-25.07-25.07一1243.73-61.41223.2673.39-410.44233.06241.09225.10118.273-161.56-61.41-317.00-237.92103.06-78.264145.61-121.34152.99-137.91-225.59177.5750-27.23-27.23東南大學(xué)畢業(yè)設(shè)計(jì)-65-梁內(nèi)力組合計(jì)算表（續(xù)）樓層截面1.35+1.40.71.2+1.4MmaxMmin|Vmax|MVMV五1-53.30100.23-52.4199.3312.65-96.19100.232131.43132.73132.7385.153-77.74-109.05-76.89-108.17-25.06-94.14109.054-36.9322.53-36.8722.313.75-58.6843.115-23.58-23.32-17.92-23.58四1-117.67178.76-112.42169.3925.56-225.29186.472193.35184.50193.35149.773-136.94-185.72-130.92-176.06-24.21-208.83192.494-41.0824.23-39.1824.4047.31-118.0888.985-29.39-27.28-25.80-29.39三1-118.61178.76-112.94169.35105.93-309.11206.452192.28183.96197.14131.313-137.65-185.69-131.34-176.0623.94-259.46212.334-40.5624.23-38.8324.4092.85-162.10126.315-28.85-26.93-24.99-28.85二1-118.78178.85-113.10169.45150.07-353.53219.772192.28183.96197.71130.743-137.50-185.63-131.19-176.0067.20-302.44225.524-40.6324.23-38.9024.40130.88-200.26158.045-28.95-27.02-25.07-28.95一1-109.29178.42-104.08169.0
