前言隨著科技的快速發(fā)展和教育的不斷深化，實(shí)驗(yàn)室已成為科研和教學(xué)的重要場(chǎng)所。實(shí)驗(yàn)樓作為這些場(chǎng)所的載體，其結(jié)構(gòu)設(shè)計(jì)的重要性日益凸顯。實(shí)驗(yàn)樓結(jié)構(gòu)設(shè)計(jì)不僅關(guān)乎建筑物的安全性和穩(wěn)定性，更直接影響到科研和教學(xué)的質(zhì)量。因此，對(duì)實(shí)驗(yàn)樓結(jié)構(gòu)設(shè)計(jì)的研究顯得尤為重要。本次設(shè)計(jì)的標(biāo)題為“星華學(xué)校實(shí)驗(yàn)樓結(jié)構(gòu)設(shè)計(jì)”。建筑結(jié)構(gòu)畢業(yè)設(shè)計(jì)是本科教學(xué)的重要環(huán)節(jié)。通過(guò)結(jié)合基本理論和現(xiàn)場(chǎng)施工經(jīng)驗(yàn)，對(duì)本工程的建筑結(jié)構(gòu)進(jìn)行了詳細(xì)的設(shè)計(jì)。設(shè)計(jì)過(guò)程中參考了國(guó)家現(xiàn)行設(shè)計(jì)規(guī)范和標(biāo)準(zhǔn)，力求全面涵蓋結(jié)構(gòu)設(shè)計(jì)的各個(gè)方面，并與工程實(shí)際密切相關(guān)，以在現(xiàn)場(chǎng)施工中發(fā)揮主要指導(dǎo)作用。

1建筑工程概況1.1工程概況1.1.1工程名稱泰安市泰山區(qū)星華學(xué)校實(shí)驗(yàn)樓1.1.2建設(shè)地點(diǎn)泰安市泰山區(qū)1.1.3工程概況本工程星華學(xué)校實(shí)驗(yàn)樓，位于泰安市泰山區(qū)。建筑面積4823.28m2。為四層框架結(jié)構(gòu)，建筑高度為，層高，設(shè)計(jì)使用年限50年。1.1.4氣象資料基本風(fēng)壓：,地面粗糙度為C類?；狙海?。1.1.5地質(zhì)條件場(chǎng)地標(biāo)準(zhǔn)凍結(jié)深度為，場(chǎng)地土類型為中硬場(chǎng)地土，建筑場(chǎng)地類別為Ⅱ類。1.1.6地震情況抗震設(shè)防烈度為7度，設(shè)計(jì)地震分組為第二組，框架抗震等級(jí)二級(jí)。1.1.7材料基礎(chǔ)：鋼筋混凝土。梁：鋼筋混凝土。柱：鋼筋混凝土。隔墻：加氣混凝土砌塊。樓板：鋼筋混凝土

2建筑結(jié)構(gòu)設(shè)計(jì)2.1截面尺寸的初步估算2.1.1板截面初估取樓板厚且?=120mm>?min2.1.2主梁截面初估截面高度，截面寬度b=(1/3~1/2)h,h/b≤4,。，取h=700mm。，取b=300mm。2.1.3次梁截面初估截面高度，截面寬度b=(1/3~1/2)h。，取h=600mm，取b=250mm，取h=450mm，取b=250mm2.1.4框架柱截面尺寸（1）按軸壓比初估框架柱截面尺寸：結(jié)構(gòu)單位面積重量,取?？蚣軌Φ氖芎奢d范圍如圖所示,框柱材料采用了C40砼,fc=19.1N/㎡,框架的抗震等級(jí)為二級(jí),軸壓比。柱的截面尺寸一般根據(jù)軸壓比限值按下列公式估算：N=βFn（2-1）Ac=N/[μN(yùn)]fc（2-2）可以初步估算框架柱截面尺寸，具體計(jì)算過(guò)程如下:框架柱軸向壓力設(shè)計(jì)值按式計(jì)算。⑤軸與B軸相交中柱N==1.25×14×(4.2+4.05)×(4.35+3.6)×4×1.0×1.1=5050.24kN=5050.24x103/0.8x19.1=330513.09取中柱截面尺寸為。⑤軸與D軸相交邊柱=1.25×14×4.2×(4.35+3.6)×4×1.1×1.1=2828.13kNAc=bchc≥N/μfc=2828.13×103/0.8×19.1=185087.04考慮到邊柱承受偏心荷載且跨度較大，故取D軸邊柱截面尺寸。⑤軸與A軸相交邊柱=1.25×14×4.05×(4.35+3.6)×4×1.1×1.1=2727.13kN=28727.13×103/0.8×19.1=178477.09考慮到邊柱承受偏心荷載且跨度較大，故取A軸邊柱截面尺寸為。角柱雖然承受面荷載較小，但由于角柱承受雙向偏心荷載作用，受力復(fù)雜，故截面尺寸取與A軸邊柱相同，即。故框架柱截面尺寸為。（2）校核框架柱截面尺寸是否滿足構(gòu)造要求：構(gòu)造要求框架柱截面高度不宜小于，寬度不宜小于。為避免發(fā)生剪切破壞，柱凈高與截面長(zhǎng)邊之比宜大于4，=3.9/0.6=6.5＞4。（3）框架柱截面高度和寬度h≥（1/10～１/15）H0=（1/10～１/15）×5100=510～340㎜故所選框架柱截面尺寸滿足構(gòu)造要求。為了簡(jiǎn)化施工，各柱截面從底層到頂層不改變。2.2柱網(wǎng)布置圖2-1柱網(wǎng)布置2.3框架計(jì)算簡(jiǎn)圖2.3.1確定框架計(jì)算簡(jiǎn)圖框架的計(jì)算單元如圖2-2，框架柱嵌固于基礎(chǔ)頂面，框架梁與柱剛接。底層柱高從基礎(chǔ)頂面算至二層樓面，室內(nèi)外高差為，基礎(chǔ)頂面至室外地坪取，故基礎(chǔ)頂面標(biāo)高至0.000的距離定為?1.20m，二層樓面標(biāo)高為3.90m，故底層柱高為5.1m。其余各層柱高從樓面算至上一層樓面（即層高），故均為3.90m。圖2-2框架計(jì)算簡(jiǎn)圖2.3.2計(jì)算各框架梁柱線剛度：由于樓面板與框架梁的混凝土一起澆筑，對(duì)于中框架梁取I=2I0，邊框架梁取見表2-1框架梁柱線剛度。表2-1框架梁柱線剛度構(gòu)件線剛度相對(duì)線高度框架梁AB跨邊框0.79中框1.05BC跨邊框0.76中框1.02框架柱二～四層1.00底層0.762.4荷載計(jì)算2.4.1恒載標(biāo)準(zhǔn)值計(jì)算(1)不上人屋面保護(hù)層：著色涂料防水層：1.5厚高分子卷材0.1找平層：20mm厚水泥砂漿0.0220=0.4找坡層：水泥焦渣找坡2%，最薄處30mm厚0.0314=0.42保溫層：60mm厚聚苯乙烯泡沫塑料板0.060.5=0.03結(jié)構(gòu)層：120mm厚鋼筋混凝土現(xiàn)澆板250.12=3.0總計(jì)：3.95(2)各層頂棚0.3(3)各層樓面磨光花崗巖樓面：1.5結(jié)構(gòu)層：0.1225=3.0總計(jì)：4.5(4)雨篷荷載厚細(xì)石混凝土面層1.00防水層0.30找坡層0.50防水層0.30找平層0.40120mm厚鋼筋混凝土現(xiàn)澆板結(jié)構(gòu)層250.12=3.0板底粉刷總計(jì)5.70(5)梁自重自重：抹灰：總計(jì)：4.6K自重：抹灰：總計(jì)：3.53K自重：抹灰：總計(jì)：1.80K(6)柱自重自重：抹灰：總計(jì)：9.7K(7)外墻自重（加氣混凝土塊）標(biāo)準(zhǔn)層：墻自重：塑鋼窗：貼面磚外墻面：內(nèi)墻面：總計(jì)：5.98K底層：墻自重：塑鋼窗：貼面磚外墻面：內(nèi)墻面：總計(jì)：7.4KN/m玻璃幕墻自重：(8)內(nèi)縱墻自重墻自重：內(nèi)墻面：總計(jì)：5.89K(9)內(nèi)隔墻自重內(nèi)隔墻：內(nèi)墻面：總計(jì)：6.57K2.4.2活荷載標(biāo)準(zhǔn)值(1)屋面和樓面標(biāo)準(zhǔn)值由《荷載規(guī)范》查得：不上人屋面：0.5樓面：2.0走廊：2.5樓梯：2.5(2)雪荷載標(biāo)準(zhǔn)值：屋面活荷載與雪荷載不同時(shí)組合，兩者中取大值。2.4.3豎向荷載下框架受荷總圖確定板傳遞給梁的荷載時(shí)，要分區(qū)格考慮。若為單向板，可沿板的短跨作中線，將板上荷載平均分給兩長(zhǎng)邊的梁；若為雙向板，可沿四角點(diǎn)作線，將板區(qū)格分為四小塊，將每小塊板上的荷載傳遞給與之相鄰的梁。本結(jié)構(gòu)樓面荷載的傳遞示意圖如圖2-3。圖2-3荷載傳遞示意圖(1)A軸——B軸間的框架梁屋面?zhèn)鹘o梁的荷載：恒載：活載：梁自重：5.38樓面?zhèn)鹘o梁的荷載：恒載：活載：梁自重：5.38(2)B軸——C軸間的框架梁屋面?zhèn)鹘o梁的荷載：恒載：活載：梁自重：5.38樓面?zhèn)鹘o梁的荷載：恒載：活載：梁自重：5.38(3)A軸柱縱向集中荷載的計(jì)算①頂層柱：女兒墻自重：（墻高900）恒荷載=女兒墻自重+梁自重+板傳荷載+次梁自重活荷載=板傳荷=9.63kN②標(biāo)準(zhǔn)層柱:恒荷載=墻自重+梁自重+板傳荷載+次梁自重+隔墻自重+柱自重=226.6kN活荷載=37.43kN(4)B軸柱縱向集中荷載的計(jì)算①頂層柱：恒荷載=梁自重+板傳荷載+次梁自重=162.17kN活荷載=板傳荷=13.86kN②標(biāo)準(zhǔn)層柱:恒荷載=墻自重+梁自重+板傳荷載+次梁自重+隔墻自重+柱自重=265.43kN活荷載=55.43kN(5)C軸柱縱向集中荷載的計(jì)算①頂層柱：恒荷載=女兒墻自重+梁自重+板傳荷載+次梁自重=145.34kN活荷載=板傳荷=7.38kN②標(biāo)準(zhǔn)層柱:恒荷載=墻自重+梁自重+板傳荷載+次梁自重+隔墻自重+柱自重=202.37kN活荷載=29.55kN(6)3軸線與1/B軸相交處主梁的集中荷載頂層恒荷載=次梁自重+板傳荷載=119.92kN活荷載=板傳荷載=11.88kN標(biāo)準(zhǔn)層：恒荷載=次梁自重+板傳荷載+內(nèi)縱墻自重+隔墻自重=187.04kN活荷載=板傳荷載=47.55kN圖2-4恒荷載作用下結(jié)構(gòu)計(jì)算簡(jiǎn)圖圖2-5活荷載作用下結(jié)構(gòu)計(jì)算簡(jiǎn)圖2.4.4風(fēng)荷載計(jì)算風(fēng)壓標(biāo)準(zhǔn)值計(jì)算公式為:（2-1）因結(jié)構(gòu)高度H=16.8m<30m,可取=1.0;對(duì)于矩形平面=1.3;可查《建筑結(jié)構(gòu)荷載規(guī)范》。將風(fēng)荷載換算成作用于框架每層節(jié)點(diǎn)上的集中荷載，計(jì)算過(guò)程如表2-2所示。表2-2風(fēng)荷載計(jì)算層次離地高度（m）（）（）416.20.7611.30.43.90.97.54312.30.7411.30.43.93.911.9328.40.7411.30.43.93.911.9314.50.7411.30.44.53.912.84圖2-6風(fēng)荷載作用下的計(jì)算簡(jiǎn)圖2.4.5水平地震作用計(jì)算該建筑物的高度為，結(jié)構(gòu)以剪切變形為主，且質(zhì)量和剛度沿高度均勻分布，故可采用底部剪力法計(jì)算水平地震作用。(1)重力荷載代表值的計(jì)算屋面處重力荷載代表值=結(jié)構(gòu)和構(gòu)配件自重標(biāo)準(zhǔn)值+0.5屋面活荷載標(biāo)準(zhǔn)值樓面處重力荷載代表值=結(jié)構(gòu)和構(gòu)配件自重標(biāo)準(zhǔn)值+0.5樓面活荷載標(biāo)準(zhǔn)值其中結(jié)構(gòu)和構(gòu)配件自重取樓面上、下各半層層高范圍內(nèi)（屋面處取頂層的一半）的結(jié)構(gòu)及構(gòu)配件自重。1)第四層重力荷載標(biāo)準(zhǔn)值的計(jì)算①女兒墻的重力荷載代表值的計(jì)算女兒墻線荷載：②第四層屋面板結(jié)構(gòu)層及構(gòu)造層自重標(biāo)準(zhǔn)值③第四層梁自重標(biāo)準(zhǔn)值：④第四層柱自重標(biāo)準(zhǔn)值：⑤第四層墻自重標(biāo)準(zhǔn)值：⑥屋頂活荷載標(biāo)準(zhǔn)值⑦第四層重力荷載代表值：=10342.92KN⑧第四層重力荷載設(shè)計(jì)值：=12747.62KN2)標(biāo)準(zhǔn)層樓面處重力荷載標(biāo)準(zhǔn)值計(jì)算①標(biāo)準(zhǔn)層樓面板結(jié)構(gòu)層及構(gòu)造層自重標(biāo)準(zhǔn)值②標(biāo)準(zhǔn)層梁自重標(biāo)準(zhǔn)值：③標(biāo)準(zhǔn)層柱自重標(biāo)準(zhǔn)值：④標(biāo)準(zhǔn)層墻自重標(biāo)準(zhǔn)值：⑤標(biāo)準(zhǔn)層樓面活荷載標(biāo)準(zhǔn)值⑥標(biāo)準(zhǔn)層重力荷載代表值：=12718.31KN⑦標(biāo)準(zhǔn)層重力荷載設(shè)計(jì)值：=17182.643)底層樓面處重力荷載標(biāo)準(zhǔn)值的計(jì)算①底層樓面板結(jié)構(gòu)層及構(gòu)造層自重標(biāo)準(zhǔn)值②底層梁自重標(biāo)準(zhǔn)值：③底層柱自重標(biāo)準(zhǔn)值：④底層墻自重標(biāo)準(zhǔn)值：⑤雨篷自重標(biāo)準(zhǔn)值⑥底層樓面活荷載標(biāo)準(zhǔn)值⑦底層重力荷載代表值：=13033.26KN⑧底層重力荷載設(shè)計(jì)值：=17560.58KN(2)框架柱抗側(cè)剛度D和結(jié)構(gòu)基本自振周期計(jì)算1)框架柱抗側(cè)剛度D的計(jì)算表2-3橫向2～4層D值的計(jì)算構(gòu)件名稱數(shù)量∑DA軸柱邊框19882239764中框241428193136B軸柱邊框31243262484中框262138289704C軸柱邊框19882239763中框241428193136表2-4橫向底層柱D值的計(jì)算構(gòu)件名稱數(shù)量∑DA軸柱邊框177758142200B軸柱邊框19997239994中框215848172672C軸柱邊框1745881396642)結(jié)構(
