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。該辦公樓建筑耐久等級(jí)為Ⅱ級(jí)，防火等級(jí)為Ⅱ級(jí)，抗震設(shè)防烈度七度（），設(shè)計(jì)地震分組為第一組，建筑場(chǎng)地類別為二類場(chǎng)地土，地基持力層為粉質(zhì)粘土土層，持力層地基承載力特征值，無軟弱下臥層，不考慮地下水影響。基本風(fēng)壓：㎡，基本雪壓：㎡。 Secondly, structural internal force bination, determine the structure of the control section of the moment , shear and axial force design value. Finally, the structure has been calculated according to the control section of the internal force of the beams, plates, columns, foundation reinforcement calculation, etc., and draw the corresponding construction drawing.Keywords:Frame。鞏固了專業(yè)知識(shí)、提高了綜合分析、解決問題的能力。建筑概況：建筑物總面積為3869， ， 。第2章 計(jì)算簡圖 。由于，應(yīng)不考慮頂點(diǎn)附加地震作用，取。上柱下柱右梁左梁上柱下柱右梁 、 恒載彎矩分配過程 恒載作用下彎矩圖 恒載作用下的剪力、軸力 AB跨梁端剪力（kN） 表31層56——46——36——26——16—— BC跨梁端剪力 表32層5—4—3—2—1— 柱軸力（KN） 表33 層邊柱A軸、D軸中柱B軸、C軸橫梁端部壓力縱梁端部壓力柱重柱軸力橫梁端部壓力縱梁端部壓力柱重柱軸力5柱頂柱底4柱頂柱底3柱頂柱底2柱頂柱底1柱頂柱底 活載作用下的框架內(nèi)力計(jì)算 梁固端彎矩本設(shè)計(jì)中各不利荷載布置時(shí)計(jì)算簡圖不一定是對(duì)稱形式，為了方便，近似采用對(duì)稱結(jié)構(gòu)隊(duì)荷載形式簡化計(jì)算。（2） 梁的彎矩方向以下部受拉為正，上部受拉為負(fù)。 本設(shè)計(jì)取=，調(diào)幅計(jì)算過程見下表42所示 彎矩調(diào)幅計(jì)算 表42荷載種類桿件跨向彎矩標(biāo)準(zhǔn)值調(diào)幅系數(shù)調(diào)幅后彎矩標(biāo)準(zhǔn)值恒載頂層ABBC五層ABBC四層ABBC三層ABBC二層ABBC活載頂層ABBC五層ABBC四層ABBC三層ABBC二層ABBC（雪載+活載）頂層ABBC五層ABBC四層ABBC三層ABBC二層ABBC 橫向框架梁內(nèi)力組合（一般組合） (單位 M:KN橫梁AB、BC跨正截面受彎承載力計(jì)算 表51層混凝土強(qiáng)度等級(jí)bh截面位置組合內(nèi)力柱邊截面彎矩(kN框架柱在壓力彎矩剪力的共同作用下，縱鋼筋按正截面抗彎矩承載力設(shè)計(jì)，箍筋按斜截面抗剪承載力進(jìn)行設(shè)計(jì)，此外要使柱具有一定的延性
