【正文】 。整個設計都符合國家現行規(guī)范要求。其中建筑荷載計算過程中垂直荷載采用迭代法計算，水平荷載采用 D 值法計算，通過荷載組合確定一榀框架結構的控制內力，最后完成一榀框架的配筋，并手繪了一榀框架配筋圖。 Classification of fire protection design of buildings for the second class, fire resistance rating for level 2. In strict accordance with the specifications for design of office buildings (JGJ672021), the code for fire protection design of buildings (GB500162021), the \load code for the design of building structures (GB500092021), the specifications for design of concrete structures (GB500102021), the specifications for design of building foundation (GB500072021),\ seismic design code \(GB500112021) in countries such as the current specification this office building on the architectural design, structural design. This design first to design of building plane, elevation, then the construction of foundation, beam, plate, column reinforcement calculation. The whole design conforms to the national current specification requirements. Used in the process of design was and AutoCAD2021 software architecture design, and using simulation software is easy to structure foundation reinforcement, with building structure CAD software to calculate reinforcement beam slab column for the whole project. Design has a certain reliability, security, creative. This account contains architectural structure selection, load calculation, the framework of reinforcement calculation, basic calculation, the stairs. The building load calculation in the process of using iterative method to calculate vertical load and horizontal load, is obtained by using the D value method determined by cross load bination of control internal force of frame structure, finally pleted a cross of reinforcement, reinforcement figure and hand draw a mon framework. Keywords: architectural design, framework, reinforcement. 土木工程專業(yè)畢業(yè)設計 5 目 錄 一、緒論 .................................................................................................................................... 7 工程概況 .............................................................................................................................. 7 主體結構選型 ....................................................................................................................... 7 設計規(guī)范、規(guī)程 .................................................................................................................... 7 材料選用 .............................................................................................................................. 7 二、 結構布置及梁柱截面估算 .............................................................................................. 8 結構布置 .............................................................................................................................. 8 計算框架梁、柱截面尺寸估算 ............................................................................................... 9 框架側移剛 度的計算 ............................................................................................................11 板配筋計算 ........................................................................................................................... 15 三、作用在所選計算單元上的恒荷載 .................................................................................. 21 標準層框架作用恒荷 載的計算 ............................................................................................... 21 頂層框架作用恒荷載的計算 ................................................................................................... 23 標準層框架作用活荷載的計算 ............................................................................................... 24 頂層框架作用活荷載的計算 ................................................................................................... 25 恒荷載計算 ........................................................................................................................... 28 四、風荷載計算 ...................................................................................................................... 35 五、橫向水平地震作用計算 .................................................................................................. 35 采用能量法計算結構的基本自 振周期 T1 ................................................................................ 35 結構等效總重力荷載代表值 eqG ............................................................................................ 36 計算水平地震影響系數 1? ..................................................................................................... 36 各層水平地震作用標準值、樓層地震剪力及樓層間位移計算 .................................................. 37 六、橫向框架的內力計算 ...................................................................................................... 38 彎矩二次分配法計算彎矩 ...................................................................................................... 38 恒荷載作用下 AB、 BC 跨梁端剪力 ABV 、 BAV 和跨中彎矩 M的計算 ...................................... 44 恒荷載作用下框架柱軸力計算 ............................................................................................... 47 七、活荷載作用下的內力計算 .............................................................................................. 48 采用二次分配法來計算活荷載作用下的框架彎矩。 土木工程專業(yè)畢業(yè)設計 8 二、 結構布置及梁柱截面估算 結構布置 結 構 布 置 及 一 榀 計 算 框 架 的 選 取 位 置 如 （ 圖 ）所示 圖 結構平面布置圖 框架結構承重方案的選擇 ： 豎向荷載的傳力途徑：樓板的均布活載和恒載經次梁間接或直接傳至主梁，再由主梁傳至框架柱，最后傳至地基。框架梁的跨度取柱截面形心之間的距離，底層柱的高度從基礎頂面算至二層樓面，取室外地坪至基礎頂面的距離為 ,則室內外 177。 邊柱取 ， 不等跨內柱取 .
