4、氣象條件溫度：最熱月平均溫度26.6oc，最冷月平均溫度-4.1oc，夏季極端最高溫度43.3oc(1955年7月23、24日)，冬季極端最低溫度-22.4oc（1970年1月4日）。相對濕度：年平均濕度63%，最熱月平均相對濕度76-80%。主導(dǎo)風(fēng)向：1、8、11月盛行北風(fēng)和西南風(fēng)，其它各月盛行西南風(fēng)，基本風(fēng)壓為0.4kn/m2。雨雪條件：年平均降雨量566.6mm，日最大降雨強(qiáng)度1856mm/日，最大積雪深度230mm。2結(jié)構(gòu)選型及初步設(shè)計(jì)2.1網(wǎng)架結(jié)構(gòu)的選型網(wǎng)架結(jié)構(gòu)選型應(yīng)遵循安全、經(jīng)濟(jì)、美觀的設(shè)計(jì)原則，能夠滿足建筑的使用功能要求，并且能夠充分發(fā)揮結(jié)構(gòu)良好的受力性能。本工程中，網(wǎng)架的長短邊

5、之比45/40=1.125，其平面接近方形，且支承方式為周邊支承，通過滿應(yīng)力優(yōu)化設(shè)計(jì)比較，宜選擇斜放四角錐網(wǎng)架。斜放四角錐網(wǎng)架的上弦與邊界軸線成450夾角，下弦正放，腹桿和下弦在同一垂直面內(nèi)。這種網(wǎng)架的上弦桿長度約為下弦桿的0.707倍，故呈短壓桿、長拉桿的情況，受力合理，節(jié)點(diǎn)匯交桿也較少。在接近正方形周邊支承時(shí)用鋼量指標(biāo)較好，適用于中小跨度建筑。2.2網(wǎng)格尺寸和網(wǎng)架高度根據(jù)數(shù)值計(jì)算和工程經(jīng)驗(yàn)，當(dāng)網(wǎng)架短向跨度為l2=(3060)m時(shí),短向網(wǎng)格尺寸宜取為（1/111/14）×l2?？紤]屋面板布置，短向網(wǎng)格數(shù)取為12，網(wǎng)格尺寸為40/12=3.333m。網(wǎng)架長向跨度較大，網(wǎng)格數(shù)劃分應(yīng)當(dāng)比

6、短跨方向多些，且網(wǎng)格尺寸宜比短向小些?？紤]以上因素，長向網(wǎng)格數(shù)取為14，網(wǎng)格尺寸為45/14=3.214m。當(dāng)網(wǎng)架短向跨度為l2=(3060)m時(shí)，網(wǎng)格高度宜取為（1/121/15）×l2，周邊支承時(shí)高度可以取小值；對于角錐體系網(wǎng)架，高度的選取還應(yīng)滿足使腹桿與弦桿的夾角接近60度的要求。綜合考慮以上因素,網(wǎng)格高度預(yù)先取為40/15=2.7m，當(dāng)結(jié)構(gòu)計(jì)算不滿足撓度要求時(shí)，再適當(dāng)加大網(wǎng)格高度。2.3網(wǎng)架結(jié)構(gòu)的支承本網(wǎng)架采用周邊支承方式，所有邊界節(jié)點(diǎn)都支承在框架梁上。框架梁的橫截面尺寸為350mm×600mm，混凝土強(qiáng)度等級為c30。在網(wǎng)架邊界的每個(gè)節(jié)點(diǎn)上都加上豎向約束（z），為

7、了防止網(wǎng)架在平面內(nèi)轉(zhuǎn)動，還要加水平約束。本網(wǎng)架中在長跨其中一邊的兩端點(diǎn)分別加上兩向水平約束（x，y）和一向水平約束（y）。2.4網(wǎng)架的屋面排水本網(wǎng)架采用在上弦節(jié)點(diǎn)上加小立柱形成排水坡的方法。沿短跨方向形成雙坡自由排水系統(tǒng)，排水坡度為6%。3網(wǎng)架結(jié)構(gòu)的計(jì)算3.1網(wǎng)架結(jié)構(gòu)上的作用3.1.1靜荷載：網(wǎng)架自重：網(wǎng)架自重包括網(wǎng)架的桿件自重和節(jié)點(diǎn)自重。網(wǎng)架大多數(shù)采用鋼材，它的自重可以通過計(jì)算機(jī)程序自動生成。上弦靜荷載： 屋面板+檁條=0.35kn/m2。下弦靜荷載： 0.1kn/m2。3.1.2活荷載：屋面活荷載：網(wǎng)架屋面為不上人屋面，屋面活荷載標(biāo)準(zhǔn)值取為0.5kn/m2 。雪荷載：雪荷載和屋面活荷載不必

8、同時(shí)考慮，取兩者中的較大值。由建筑結(jié)構(gòu)荷載規(guī)范gb50009查得雪荷載為0.35kn/m2，小于屋面活荷載，故不考慮雪荷載。風(fēng)荷載： 對于周邊支承，且支座節(jié)點(diǎn)在上弦的網(wǎng)架，風(fēng)荷載由四周墻面承受，計(jì)算時(shí)可不考慮風(fēng)荷載的影響。積灰荷載： 網(wǎng)架作為倉儲屋蓋，積灰荷載較小，可以不考慮積灰荷載的影響。吊車荷載： 網(wǎng)架結(jié)構(gòu)中不設(shè)吊車，故不必考慮吊車荷載。3.1.3溫度變化作用與地震作用本網(wǎng)架短向跨度為40米，屬于中等跨度，溫度變化作用對網(wǎng)架受力影響較小，因此可忽略溫度變化作用對網(wǎng)架的影響。該工程所在地區(qū)的抗震設(shè)防烈度為7度，按照我國網(wǎng)架結(jié)構(gòu)設(shè)計(jì)與施工規(guī)程jgj7-91的規(guī)定，可以不進(jìn)行豎向抗震驗(yàn)算和水平抗

9、震驗(yàn)算。3.1.4荷載組合當(dāng)無吊車荷載、風(fēng)荷載和地震作用時(shí)，網(wǎng)架應(yīng)考慮以下荷載組合：a.靜荷載+活荷載b.靜荷載+半跨活荷載c.網(wǎng)架自重+半跨屋面板自重+施工荷載當(dāng)采用輕型屋面或屋面板對稱布置時(shí)，可不考慮后兩種荷載組合。因此，本工程中只考慮第一種荷載組合，共有四種工況組合情況：（1）、1.2靜荷載 1.2×（0.35+0.1）=0.54kn/m2；（2）、1.2靜荷載+1.4活荷 1.2×（0.35+0.1）+1.4×0.5=1.24 kn/m2；（3）、1.35靜荷載+0.98活荷載 1.35×（0.35+0.1）+0.98×0.5=1.10

10、 kn/m2；（4）、1.0靜荷載+1.0活荷載 1.0×（0.35+0.1）+1.0×0.5=0.95 kn/m2。3.2桿件的內(nèi)力計(jì)算與輸出在cad2004中建立網(wǎng)架模型,然后導(dǎo)入mst中,利用mst對網(wǎng)架桿件進(jìn)行內(nèi)力分析，從而得到各桿件的內(nèi)力情況，詳見下面表-1所示。表-1 桿件的軸力范圍桿件號軸力范圍（kn）桿件號軸力范圍（kn）桿件號軸力范圍（kn）1-7.8-4.128-64.5-33.955-42.2-2222.24.229-45.6-23.856-27.7-14.43-7-3.730-6.9-3.557-27.7-14.44-21.4-11.231-39.4
