meters, construction of five layers, layerstorey , two to five layers high are , length , width , height . The building consists of three functional areas: meeting rooms, offices and other facilities, the architectural design of traffic flow, meet the requirements of various rooms, shape, beautiful facade. Reinforced concrete structural system framework, the foundation is an independent foundation under column. The office building durable grade Ⅱ, grade Ⅱ fire rating, seismic intensity VII (basic design earthquake acceleration of ), grouped into the first set of seismic design, construction site category II site soil, ground support stratum of silty clay soil, the foundation bearing capacity values held power layer foundation depth as , lying without the weak layer, without considering the impact on groundwater. Basic wind pressure: / m, the basic snow pressure: / m.、In conscientiously implement the applicable, security, economic, aesthetic principle, study collected various office design. According building design specifications and other relevant standards and design requirements and geological information provided in accordance with the first building structure, design local node after the first step of the overall design layout design. First, according to the design of the building program and the choice of materials and practices, to determine the structure calculation diagram, carry loads and internal forces calculation, draw the corresponding internal force diagram。 ReinforcementIII濮陽市中原油田辦公樓建筑結(jié)構(gòu)設(shè)計(jì)引 言畢業(yè)設(shè)計(jì)是大學(xué)培養(yǎng)目標(biāo)實(shí)現(xiàn)的重要階段,是畢業(yè)前的綜合學(xué)習(xí)階段,是深化、拓寬、綜合教和學(xué)的重要過程,是對大學(xué)期間所學(xué)專業(yè)知識(shí)的全面總結(jié)。畢業(yè)設(shè)計(jì)的將近四個(gè)月里,在指導(dǎo)老師的幫助下,經(jīng)過資料查閱、設(shè)計(jì)計(jì)算、論文撰寫以及外文的翻譯,加深了對新規(guī)范、規(guī)程、手冊等相關(guān)內(nèi)容的理解。以上所有這些從不同方面達(dá)到了畢業(yè)設(shè)計(jì)的目的與要求。工程位置:濮陽市區(qū),地勢平坦。該建筑立面為了滿足采光和美觀需求,設(shè)置了大面積的玻璃窗。工程地質(zhì)條件:建筑場地為二類場地土,持力層地基承載力為特征值為f0k=150kpa,無軟弱下臥層;抗震設(shè)防:7度,第一組;建筑耐久等級、防火等級均為Ⅱ級;風(fēng)荷載:全年主導(dǎo)風(fēng)向?yàn)楸憋L(fēng),基本風(fēng)壓為=;雪荷載:基本雪壓為S0=(水平投影)冰凍深度:室外天然地面以下800mm。 框架柱:按柱高考慮: 柱高 所以柱均采用500mm500mm;混凝土:均采用C30級;鋼筋:采用HPB235,HRB400級;維護(hù)墻采用200mm厚非承重空心磚(190mm190mm190mm,),M5混合砂漿砌筑。 框架頂點(diǎn)的假想水平位移 表24層總位移54321 3)地震作用計(jì)算在二類場地,7度設(shè)防區(qū),設(shè)計(jì)地震分組為第一組情況下,結(jié)構(gòu)的特征周期,水平地震影響系數(shù)最大值。(1)橫梁固端彎矩 1)頂層橫梁: 自重作用:板傳來的恒載作用 2)二五層橫梁:板傳來的恒載作用(2) 縱梁引起的端部附加彎矩頂層外縱梁:(逆時(shí)針為正)樓層外縱梁∶頂層中縱梁∶樓層中縱梁∶橫向框架的節(jié)點(diǎn)不平衡彎矩為通過該節(jié)點(diǎn)的各桿件在節(jié)點(diǎn)處的固端彎矩與通過該節(jié)點(diǎn)的縱梁引起柱端橫向附加彎矩之和,根據(jù)平衡原則,節(jié)點(diǎn)彎矩的正方向與桿件彎矩方向相反,一律以逆時(shí)針方向?yàn)檎?。?jié)點(diǎn)分配順序;。當(dāng)雪荷載與活荷載相差不大時(shí),可近似按滿跨活荷載布置。 地震作用分項(xiàng)系數(shù) 表41地震作用僅計(jì)算水平地震作用0僅計(jì)算豎向地震作用0同時(shí)計(jì)算水平與豎向地震作用本章各內(nèi)力組合時(shí)的單位及方向:(1) 柱的內(nèi)力及梁的剪力仍沿用結(jié)構(gòu)力學(xué)的規(guī)定:柱彎矩 順時(shí)針為正,逆時(shí)針為負(fù);梁、柱軸力 柱受壓為正,受拉為負(fù);梁、柱剪力 順時(shí)針為正,逆時(shí)針為負(fù)。應(yīng)先對豎向荷載作用下框架梁的彎矩進(jìn)行調(diào)幅,在與水平作用產(chǎn)生的框架梁彎矩進(jìn)行組合。柱每層有兩個(gè)控制截面,即柱頂和柱底。m;V:KN) 表45桿件跨向截面內(nèi)力荷載種類內(nèi)力組合及相應(yīng)的N及相應(yīng)的M及相應(yīng)的M恒載滿跨活荷載風(fēng)荷載++(+)+活左風(fēng)右風(fēng)左風(fēng)右風(fēng)頂層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 四層柱 A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 續(xù)表?xiàng)U件跨向截面內(nèi)力荷載種類內(nèi)力組合及相應(yīng)的N及相應(yīng)的M及相應(yīng)的M恒載滿跨活荷載風(fēng)荷載++(+)+活左風(fēng)右風(fēng)左風(fēng)右風(fēng)三層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 二層柱 A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 續(xù)表?xiàng)U件跨向截面內(nèi)力荷載種類內(nèi)力組合及相應(yīng)的N及相應(yīng)的M及相應(yīng)的M恒載滿跨活荷載風(fēng)荷載++(+)+活左風(fēng)右風(fēng)左風(fēng)右風(fēng)底層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 橫向框架內(nèi)組合(考慮地震作用) 表46桿件跨向截面內(nèi)力荷載種類內(nèi)力組合及相應(yīng)的N及相應(yīng)的M及相應(yīng)的M恒載(雪+活)地震作用〔恒+(雪+活)〕+向左向右向左向右頂層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 四層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 三層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 續(xù)表二層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 底層柱A柱柱頂M N 柱底M N B柱柱頂M N 柱底M N 第5章 框架梁、柱截面設(shè)計(jì)計(jì)算出框架梁柱控制截面內(nèi)力后,應(yīng)該分別按照無地震作用效應(yīng)組合內(nèi)力和有地震作用效應(yīng)組合內(nèi)力進(jìn)行截面設(shè)計(jì)。 材料選擇混凝土強(qiáng)度等級,縱筋采用,箍
