【正文】 本科生畢業(yè)論文（設(shè)計） 題 目： 輕型門式剛架廠房設(shè)計 姓 名： 系 別 ： 專 業(yè)： 年 級： 學(xué) 號： 指導(dǎo)教師 ： 職稱： 講師 20 年 月 日 中文摘要 本工程為某輕型鋼結(jié)構(gòu)門式剛架設(shè)計。根據(jù)畢業(yè)設(shè)計任務(wù)書的要求，分建筑與結(jié)構(gòu)兩部分進行設(shè)計。 建筑部分，通過查閱《鋼結(jié)構(gòu)設(shè)計規(guī)范 GB500172021》、《簡明鋼結(jié)構(gòu)設(shè)計手冊》、《福建省建筑設(shè)計標(biāo)準(zhǔn)圖籍》等相關(guān)資料，將門式剛架廠房設(shè)計為 13跨，每跨的間距為 30m，總的 建筑面積為 2160m2。該單層門式剛架結(jié)構(gòu)是以輕型焊接 H 型鋼（變截面）作為主要承重骨架，用冷彎薄壁型鋼（ C 型）做檁條、墻梁；以壓型鋼板做屋面、墻面；采用 80mm 玻璃棉作為保溫隔熱材料并適當(dāng)設(shè)置支撐的一種輕型房屋結(jié)構(gòu)體系。 結(jié)構(gòu)部分，根據(jù)已形成的建筑圖及其相關(guān)要求，查閱《建筑結(jié)構(gòu)荷載規(guī)范GB500092021》、《冷彎薄壁型鋼結(jié)構(gòu)技術(shù)規(guī)范 GB500182021》、《鋼結(jié)構(gòu)連接節(jié)點設(shè)計手冊》、《房屋建筑鋼結(jié)構(gòu)設(shè)計》等相關(guān)規(guī)范和一定量的實際工程設(shè)計圖，對每榀剛架的最不利荷載進行計算，利用 PKPM 軟件完成剛架的 合理截面計算，然后通過設(shè)計規(guī)范的相關(guān)要求，對剛架梁、柱、支撐、檁條等構(gòu)件進行穩(wěn)定性計算，用 AUTOCAD2021 分別繪制出設(shè)計圖。最后，整理計算書并出圖。 關(guān)鍵詞 輕型鋼結(jié)構(gòu)門式剛架 建筑 結(jié)構(gòu) 規(guī)范 設(shè)計圖 Abstract This project is a light steel portal frame design. Under the graduation requirements of the task book, divided into two parts building and structure design。 Building part, by access to the 《 Steel Structure Design Specification GB500172021》 、《 Concise Steel Structure Design Manua》 、 《 The Fujian Architectural Design Standard Plans》 and other relevant information, the gabled designed to 13 across each crossa 30m, total construction area for 2160m2. The singlestorey gabled structure is to light welding hshaped steel (uniform) as the main load bearing frame, with coldformed steel (type c) do Purlin beams and walls。 to steel do roofing, wall。 a 80mm glass wool as an insulation material and appropriate settings supported a light house in architecture. Structural elements, according to the established building plans and related requirements, consult the《 Building Structure Load Code GB500092021》 、 《 coldformed steel structures specification GB500182021》 、 《 steel structure connection node design manual》 、《 the housing construction steel structure design》 and other related specifications and a certain amount of actual engineering design, each truss pin of the most unfavorable load calculations, use PKPM software plete the rigid frame of reasonable section, and then through the design specifications of requirements on the rigid frame beams and columns, such as support, purlins, ponent for stability with AUTOCAD2021 respectively out design. Finally, a finishing account book and plot.
