活荷载内力计算屋面布活荷载好了

六活荷载内力计算（屋面布活荷载）一、活荷载计算1．屋面框架梁线荷载标准值q5DE=2.0×4.2=8.4kN/mq5CD=2.0×4.2=8.4kN/mq5BC=2.0×4.2=8.4kN/m2．楼面框架梁线荷载标准值qDE=2.0×4.2=8.4kN/mqCD=2.0×4.2=8.4kN/mqBC=2.0×4.2=8.4kN/m3．屋面框架节点集中荷载标准值B、C、D、E轴线纵向框架梁传来的活荷载4.22×2.0/2=17.64kN横向次梁CD/DE传来的活荷载(1-2×0.292+0.293)×2.0×4.2×7.2/2=25.89kN横向次梁BC传来的活荷载(1-2×0.292+0.293)×2.0×4.2×5.4/2=19.42kN纵向次梁传来的活荷载2.0×8.4×1.8/2=15.12kN则顶层边节点A集中荷载为：Q5A=15.12KN顶层边节点E集中荷载为：Q5E=43.53KN顶层中节点B集中荷载为：Q5B=52.18kN底顶层记中减节点柱C断集中荷载璃为：俩Q垄5恰C白=巩80.5尚9惜kN浓顶层中节吉点确D国集中荷载售为：诚Q它5径D缸=逆87.0势6绩kN落4谣．楼面框痰架节点集炊中荷载标谋准值嗓B坝、永C俊、达D偏、样E惕轴线纵向凑框架梁传默来的活荷推载拴4.2砍2织×言2.0/殊2=17根.64k尚N炉横向销次梁央CD/D幕E披传来的活扛荷将载吓宁(稼1-2×巧0.2哭9熊2棍+0.2姥9工3珠)×饱2.0袜×研4.2家×7.2焰/2=胡25.8头9椒kN比横向婶次梁姿B吃C雁传来的活军荷过载赴漠(长1-2×造0.2西9箩2帝+0.2拦9粘3永)×差2.0恰×姑4.2倚×涝5.4浆/2=而19.4被2侄kN桂纵向席次梁拌传来的活秒荷话载围2.0耳×贪8.4摔×蛋1.8洒/最2=15汽.12k妹N烦马赚眉印顾易暗则顶层边秩节点疯A桃集中荷载找为：难Q剖A稻=沟15.1脉2贪K抢N旦顶层边节析点离E用集中荷载桑为：您Q汗E颠=挺43.5湿3作K倡N运顶层邪中某节点圾B迅集中荷载浮为：秆Q撒B寸=尺52.1鞠8辛kN扩顶层证中锯节点歌C饮集中荷载辆为：扯Q薄C质=躺80.5伴9样kN口顶层中节艰点仓D耻集中荷载钥为：墨Q圆D忍=拼87.0喉6穷kN坝二坐弱活荷桥载作用下器内力计算惊1话．计算简概图息2吉．固端弯肌矩计算菌将净A价B以跨悬挑上滴的力化作错一个集中眯力和一个卖弯矩作用抖于蛇B塘上。栗顶顷层蜡E劣D崖跨腐私顶传层份D绘C稻跨血贴顶趟层层C敞B辫跨执中间层压ED促跨沸位中间叼层族D撒C冤跨才铃中间妥层螺C疲B钻跨钉箱3浙．分层计闷算弯矩1）顶层歪内力计算结过程如下抚（单位样：粪kN哀∙究m扩）提1-5枯1-2费2-1众2-6相2-3雄3-2谎3-7桃3-4枝4-3劝4-8奸0.37乐6鹅0.62墓4跑0.30钱1补0.39拣8抹0.30穷1虑0.38怠9辜0.48脖5秧0.12挪6练0.35陆0.65吸27.2辫2揪-31凤31棵-31像31昨-17.歌44份17.4座4付11.6厚6控19.3仍4磁9.67链-1.4策6介-2.9谷1亦-3.8壮5等-2.9疮1厘-1.4丹6块-2.3刚6猜-4.7肌1偏-5.8喜7忠-1.5谢2致-0.7草6污1.85完3.69爪6.85燕-0.3学6协-0.7触2伟-0.8华8买-0.2焰3督-0.1岛2绢0.41摘0.82器1.08衣0.82栽0.41我0.39扬0.66临0.33售-0.0柜5栗-0.1朗-0.1留3液-0.1碑-0.0淡5俱-0.0城7破-0.1猎4麻-0.1们7骑-0.0阀5布-0.0摸3间0.05分0.1浸12.0畅5但-12.抢1尚38.8路1种-2.9量-35.筝98饭24.3室3拦-6.9头2骗-17.共39药20.2载7植6.95容M烧图如下（茫单位瘦：浅kN屋∙极m茶）袭栽2返）中间层肾内力计算墙过程见下拦页（单位住：州kN收∙化m疑）忍5-1团5-9念5-6初6-5笼6-2拒6-10哄6-7排7-6葱7-3缩7-11鱼7-8找8-7披8-4重8-12帅0.27薯3理0.27奴3其0.45鬼4驳0.22逮2疑0.27岗8漠0.27术8般0.22厕2德0.26役2醉0.32键7本0.32努7列0.08越4予0.21窄2上0.39寨4那0.39惑4退27.2损2孟-31框31扯-31辜31邮-17.有44伞17.4门4功8.46场8.46耀14.0支7廉7.04把-0.7故8雷-1.5傅6宜-1.9隙6劝-1.9筋6障-1.5毒6脸-0.7私8定-1.6渴8着-3.3乌5穿-4.1便8章-4.1络8须-1.0常7掏-0.5钩4绞1.1秒2.19刃4.07横4.07筹-0.1铜5爪-0.2产9助-0.3喜6滋-0.3进6列-0.0圾9葬-0.0滴5隐0.21钢0.41穗0.51通0.51踏0.41六0.21君0.16道0.16箭0.26组8.62捎8.62面-17.桂2讲36.8作9盗-1.4增5妙-1.4西5废-33.具98软26.7概9彩-4.5孩4踪-4.5找4形-17.础5笔19.0走4忠4.07啊4.07番M枪图如下（贞单位眼：烦kN傻∙各m颗）3）底层围内力计算弄过程如下挺（单位截：袄kN调∙廉m访）棵5-1邀5-9坝5-6亮6-5等6-2够6-10狭6-7那7-6池7-3繁7-11序7-8玩8-7监8-4恭8-12勾0.29狭2包0.22伸3曾0.48蹦5爬0.23桥8夹0.29新7蕉0.22帮7印0.23淋8息0.28啄4筝0.35婆4坏0.27描0.09磨2器0.23忘4蝇0.43组5量0.33单1坛27.2件2跨-31扔31否-31朽31按-17.恋44撤17.4恰4发9.05躬6.91马15.0逆4炉7.52由-0.9申-1.7占9藏-2.2槐3钞-1.7怪1旱-1.7耕9耐-0.9立-1.8倒-3.6芹-4.4满8童-3.4业2翅-1.1冰6屈-0.5内8合1.21刃2.42节4.51阶3.43讯-0.1艇7杀-0.3烤4留-0.4娘3掀-0.3讽3系-0.1镇1煤-0.0奸6非0.24以0.47房0.59舍0.45陶0.47益0.24浆0.19恩0.15灰0.32脉0.16投-0.0庸2动-0.0歪4瓦-0.0漆5顿-0.0选4末-0.0两4锯-0.0口2跳-0.0化3担-0.0塔6铃-0.0躲8诚-0.0犹6射-0.0悦2交-0.0犬1虾0.02矛0.03旬0.02流9.24惕7.06乳-16.音32劝37.3轻2侄-1.6纹9姑-1.3娇-34.啦36伐26.3梢2岭-4.9农9匠-3.8仁1殃-17.腹5觉19.2刃3秘4.54具3.45贼M杰图见下页江（单位陶：缎kN银∙魂m汪）售4移．不平衡枣弯矩分配税计算过程沟如下（单病位勤：能kN律∙钉m让），方框箩内为原不愿平衡弯矩隆左梁支上柱茂下柱悠右梁编0.14奴0.59忘-0.4农8凉1.79循2.87蓄-1.8属-0.2溉8描-0.4犁8恨0.14猪-0.7舒8述-1.5侵1租0.19茄0.48摔1.36奴4.02报2.14初0.32解-0.9框7夕-0.5沟7外1什-2.3狼1绸-1.0府6灰-0.7易8卖2.32研0.87伶0.99束2.87屈-3.1暖-0.0聚8昆-0.4即8庭0.32胡-0.2拉6羞-1.5齿1沈0.32饮-0.0毛9剪1.36承2.87奴1.3扮0.21姥-0.4种8层-0.2剃1蹲0.79衔-1.5胳1晶-0.5苍2樱-0.5某8拥1.36炕0.29蚁1.3坐2.87盯-2.6兴-0.2汁1长-0.4话8策0.21惹-0.5雾2挂-1.5每1熄0.25钓0.29毯1.36殊2.87替1.25浴0.23园-0.4杰8缓-0.1遭9叠0.83旗-1.5猫1判-0.4参7可-0.6刚1结1.36古0.23侦1.46西3.08撞-2.7井-0.2行7危-0.5遇6院0.23石-0.6上2徒-1.6炉6惹0.27角0.38蒸1.51尺2.87伴2.03摘0.11屯-0.4恋8积-0.3暑4帅0.43脂-1.5罚1独-0.9咐8隐-0.3会2匠1.36傻0.77兽-0.6纲-1.4啄0.11锯0.11忍0.41辫0.14硬-0.4如5租不平衡弯波矩调整之源后即可得橡出活荷载滑作用下框钟架弯矩图浸，见下页停（单位攀：祸kN何∙出m功，括号内泊为调幅后总的弯矩值帽）糠M忍图（单位冶：游kN康∙球m予）粮5房．跨中弯建矩计算妙因为楼面抵活载是按响满布计算驼的，故跨酸中弯矩应铺乘为以雾1.自2离进行放大叹。僚6骆．剪力计棒算俯7敌．轴力计档算齐框架结构秘的剪力图腿和轴力图裕如下（单麦位器：叫k极N丑）瞧V恒图（单位便：炮k茶N滩）哨肆N普图（单位发：杂k贡N递）度8蔑．弯矩调排幅裹边跨：端培部弯矩值谊乘岗以锅0.8纠5应，跨中弯忍矩值乘失以房1.2鸦中跨：端滚部弯矩值照乘告以狂0.8喊5置，跨中弯需矩值乘苗以忙0.9协将调幅后拣的弯矩值棉表于框架霜弯矩图的塞（）内棋9背．梁端柱谜边剪力与欧弯矩原V(k遇N)急M(k朵N范∙主m)再17.8报2平-24.相72王22.7供6玻-19.否72总13.2绪-14.饭22研15.1六2宾-7.6浑5与31.3汪9督-29.暑15窄18.4灯1节-13.环43姥16.7昏2刊-23.甘44愤18.9地5菠-23.持59障22.0这6炎-20.薄42方13.4严8胀-13.斥94烟15.1边2葵-12.妙46老29.8细1迷-27.针36共20.6宰6索-13.独46歪15.5努6魂-23.霞44撇18.9功-23.允64疤22.1踩-20.陆38眠13.4加6真-13.付96团15.1品2有-12.看48终29.8截-27.材35敢20.6泪8畅-13.洽46病15.
