【正文】 ng structural design of teaching building. This building is four teaching buildings, structure system for steel frame system. Steel frame system refers to the housing along vertical and horizontal adopt frame as a bearing and resist the lateral force is the main ponent of structure, and can generally be divided into no supporting frame and a supporting frame two forms, the structure is no supporting frame system, only by the steel column and steel girders, seismic fortification intensity8 degrees, design basic acceleration, the longitudinal frame, beam and column connection with rigid connection.Frame structure system has the advantage of being able to provide more interior space, building layout is flexible, can adapt to various types of functions, simple structure, easy standardization and formalization of ponent, fast construction speed, good in layers structure is concerned, this system is a more economical and reasonable, the use of a wide range of structural system, and monly used in the number of not more than 30story highrise building. Steel structure of the main types of building structures, is the modern construction than the ordinary form of the structure. Steel structure and a reinforced concrete structure, its uniformity, high strength, high construction speed, good shock resistance and high recovery rate of superiority, the load under the same conditions, the quality of the light steel member. From the destroyed aspect, steel structure is in advance to have a larger deformation premonition, which belongs to the ductile fracture structure, can anticipate danger, thereby avoiding. But steel structure has some shortings, such as the steel structure is easily corroded, so the steel structure frame and do some anticorrosion measures, for example on the steel column and steel beam coated with anticorrosive coating can improve the corrosion resistance of steel structure. Steel structure is characterized by the largest heat but not fire, in case of fire, steel structure bearing capacity decreased dramatically due to accidents, so the school the crowded building must consider the requirement of fire. Graduation design is a university for four years to study civil engineering knowledge system, a prehensive inspection and summary, university education is important summary. By graduating from design to do, make me on the steel structure of the study and research of more indepth, deepened my for civil engineering specialty knowledge and understanding. In the plete set of process through access to a variety of literature data, code case, not only to expand my knowledge, but also cultivate our independent thinking, the ability to access the information.Key words: steel structure, frame, rigid, structure第一章 結構設計方案概述要求：達拉特旗某鋼框架教學樓建筑結構設計，已知工程概況如下：本建筑為達拉特旗某鋼框架教學樓，位于九內蒙古達拉特旗。屋面為不上人屋面，采用改性瀝青防水，苯板保溫。地質條件：擬建場地地形平坦，Ⅱ類場地。外墻做法為：300mm厚陶粒空心砌塊； 60mm厚輕質GRC保溫板； 12mm厚1：3水泥砂漿找平層 8mm厚1：2水泥砂漿面層 25mm厚貼瓷磚墻面（包括水泥砂漿打底）。框架梁、柱均采用熱軋H型鋼。該建筑抗震設防類別為丙類，地震作用及抗震措施均按設防烈度考慮。框架梁、柱均采用焊接工字形截面。m）（邊框架）（kN第四章 荷載計算(不上人屋面) 4mmAPP改性瀝青防水卷材 25mm厚1:8水泥膨脹珍珠巖找坡層（2%） 15= 20mm厚1:3水泥砂漿（砂漿中摻聚丙烯）找平層 20= 35mm厚擠塑聚丙乙烯泡沫板保溫層 = 隔離層聚酯纖維布一層 10mm厚卵石保護層 18= 結構層壓型鋼板鋼筋混凝土結構 += V型輕鋼龍骨吊頂 合 計 活載：不上人屋面 雪載 重力荷載代表值計算時取雪荷載。結構自振周期 層數(kN)(kN)(104 KN/m)（m）（m）4321考慮非結構構件影響取= （1）采用底部剪力法計算水平地震作用設防烈度8度，（第一組），則；Ⅱ類場地，阻尼比；＜=＜＝。m)(kN)(kN)(kN)(kN)43—2—1—（4）樓層地震剪力調整按抗震規范規定：各樓層地震剪力，剪力系數，具體計算如下表所示：樓層地震剪力調整 層(kN)(kN)(kN)(kN)備注4滿足3滿足2滿足1滿足由以上計算可知各樓層地震剪力均滿足要求。從以上表計算可知，地震作用下側移滿足要求。—反彎點到柱下端結點的距離，即反彎點高度。—下層層高變化修正系數。 = = 柱剪力計算： 。彎矩二次分配法是一種近似計算方法，即將各節點的不平衡彎矩同時作分配和傳遞，分配兩次傳遞一次。橫向框架梁、柱的彎矩分配系數 位置節點編號 邊節點5———4——3——2——中間節點10——9872）恒載作用下的彎矩二次分配上柱下柱左梁右梁上柱下柱左梁　　　　　　　　　　　　　165165　　　　　　　　　　　165165　　　　　　　　　　　165165　　　　　　　　　　　3） 活載作用下的彎矩二次分配上柱下柱左梁右梁上柱下柱左梁
