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(jié)構(gòu)設(shè)計方案概述要求:達拉特旗某鋼框架教學(xué)樓建筑結(jié)構(gòu)設(shè)計,已知工程概況如下:本建筑為達拉特旗某鋼框架教學(xué)樓,位于九內(nèi)蒙古達拉特旗。通過做畢業(yè)設(shè)計,使我對鋼結(jié)構(gòu)的學(xué)習(xí)和研究更為的深入,深化了我對土木工程專業(yè)知識的認知和理解。鋼結(jié)構(gòu)最大的特點是耐熱但不耐火,如果發(fā)生火災(zāi)則鋼結(jié)構(gòu)承載力急劇下降從而引起事故,所以在學(xué)校這種人群密集型建筑一定要考慮防火要求。從被破壞方面看,鋼結(jié)構(gòu)是在事先有較大變形預(yù)兆,屬于延性破壞結(jié)構(gòu),能夠預(yù)先發(fā)現(xiàn)危險,從而避免。鋼結(jié)構(gòu)是主要的建筑結(jié)構(gòu)類型之一,是現(xiàn)代建筑工程中較普通的結(jié)構(gòu)形式之一。鋼框架體系是指沿房屋的縱向和橫向均采用框架作為承重和抵抗側(cè)力的主要構(gòu)件所構(gòu)成的結(jié)構(gòu)體系,且一般可分為無支撐框架和有支撐框架兩種形式,本結(jié)構(gòu)為無支撐框架體系,僅由鋼柱和鋼梁組成,抗震設(shè)防烈度8度,框架的縱、橫梁與柱的連接采用剛性連接。鋼結(jié)構(gòu)畢業(yè)設(shè)計計算書引 言本設(shè)計為內(nèi)蒙古達拉特旗某鋼框架教學(xué)樓樓建筑結(jié)構(gòu)設(shè)計。此建筑為四層教學(xué)樓樓,結(jié)構(gòu)體系為鋼框架體系。框架結(jié)構(gòu)體系的優(yōu)點是能夠提供較大的內(nèi)部使用空間,建筑平面布置靈活,能適應(yīng)多種類型的使用功能,結(jié)構(gòu)簡單,構(gòu)件易于標準化和定型化,施工速度快,對層數(shù)不錯的高層結(jié)構(gòu)而言,該體系是一種比較經(jīng)濟合理、運用廣泛的結(jié)構(gòu)體系,而且常用于層數(shù)不超過 30 層的高層建筑。鋼結(jié)構(gòu)與普通鋼筋混凝土結(jié)構(gòu)相比,其勻質(zhì)、高強、施工速度快、抗震性好和回收率高等優(yōu)越性,在荷載相同的條件下,鋼構(gòu)件的質(zhì)量輕。 但鋼結(jié)構(gòu)也有一定的缺陷,比如鋼結(jié)構(gòu)容易被腐蝕,所以要在鋼結(jié)構(gòu)框架做一定的防腐措施,例如在鋼柱和鋼梁上涂防腐涂料可提高鋼結(jié)構(gòu)的抗腐蝕能力。 畢業(yè)設(shè)計是大學(xué)四年來對所學(xué)土木工程知識的一次系統(tǒng)、全面的考察和總結(jié),是大學(xué)重要的總結(jié)性教育。在做畢設(shè)的過程中通過查閱各種文獻資料、規(guī)范案例,不僅拓展了我的知識面,也培養(yǎng)了我獨立思考、查閱資料的能力。共四層,全部為教學(xué)用房,總建筑面積:5000。墻體采用陶??招钠鰤K,室內(nèi)地面采用大理石地面。結(jié)構(gòu)形式為鋼框架——支撐體系。抗震設(shè)防烈度為8度,地震分組為1組。建筑地層一覽表 序號巖土分類土層深度(m)厚度范圍(m)地基土承載力(kPa)樁端阻力(kPa)樁周摩擦力(kPa)1雜填土———2粉土—160—103粉砂—150—254礫砂2202400305粉細砂180350060注:地下穩(wěn)定水位距地表9m,表中給定土層深度由自然地坪算起。本工程采用實木門和塑鋼玻璃窗。 內(nèi)墻做法為:200mm厚陶??招钠鰤K; 18mm厚水泥砂漿找平; 2mm厚麻刀石灰面層。采用鋼結(jié)構(gòu)框架體系結(jié)構(gòu)。樓板采用壓型鋼板鋼筋混凝土組合樓蓋體系,其中壓型鋼板只作為永久性模版使用,承受施工荷載和混凝土的重量;樓梯為現(xiàn)澆混凝土板式樓梯;基礎(chǔ)采用柱下獨立混凝土基礎(chǔ),結(jié)構(gòu)布置如圖 。 材料選用所有構(gòu)件及零件均采用Q235B;組合樓板混凝土強度等級C30,基礎(chǔ)混凝土強度等級C30,鋼筋為HRB335級及HRB400級。具體計算方法如下:采用底部剪力法計算水平地震作用;采用修正反彎點法(D值法)計算水平地震作用下的框架內(nèi)力;采用彎矩二次分配法,計算豎向荷載作用下框架內(nèi)力。鏈接方式采用焊縫,螺栓連接。樓板采用壓型鋼板鋼筋混凝土組合結(jié)構(gòu);樓梯板和平臺板采用鋼筋混凝土樓板;基礎(chǔ)采用柱下獨立基礎(chǔ)。如圖 柱、梁選用見下表: 構(gòu)件截面參數(shù)結(jié)構(gòu)構(gòu)件初選截面參數(shù) 項目截面尺寸構(gòu)件截面特性重量(mm)(mm)(mm)(mm)(mm)A()()(mm)(mm)M(kN/m)框架柱5024702545220329551502830000432950000框架梁60620120566121497786656000021760000橫向次梁350175013324762911298000009838000第三章 框架梁柱剛度計算 層間側(cè)移剛度`算鋼材的彈性模量N/mm2框架梁線剛度 梁編號截面尺寸(mmmm)跨度(mm)AB(CD)慣性矩=(mm4)(邊框架)BC慣性矩=(mm4)(中框架)(kNm)(中框架)LAB(CD)200600780010398720001299840000LBC200600330010398720001299840000柱的線剛度按式計算框架柱線剛度 層柱高h(m)軸柱慣性矩()軸柱子線剛度(kNm)修正系數(shù)修正系數(shù)(104 KN/m)(104 KN/m)2~4中框架中柱(28根)邊柱(
