劉光眾，曹平周 2010/6/20
摘要：框架結(jié)構(gòu)中梁常用的類型有鋼梁、組合梁、型鋼混凝土梁和普通鋼筋混凝土梁四種。將某框架結(jié)構(gòu)中的主梁分別按四種類型進(jìn)行設(shè)計(jì)，并對(duì)其經(jīng)濟(jì)性和力學(xué)性能進(jìn)行了對(duì)比分析，提出設(shè)計(jì)建議。

comparsion and analysis of main girder of four types in rigid frame
Liu guangzhong，Cao Pingzhou (College of Civil and Transportation Engineering, Hohai University, Nanjing, Jiangsu, China) Abstract:There is four types of beams commonly used in the frame structure,namely, steel beam, composite beam, steel reinforced concrete beams and reinforced concrete beams.In this article,a main girder in a frame structure is designed into four types,separately.Then,their economic and mechanical properties is compared,and design suggestion is also proposed.Keyword: main girder in rigid frame;economic property; comparsion analysis
框架是多層建筑常用的結(jié)構(gòu)體系，常采用梁與柱剛接的連接方式。為實(shí)現(xiàn)房屋的靈活分割，設(shè)計(jì)時(shí)常采用大柱網(wǎng)，樓蓋采用主次梁構(gòu)成的梁格體系。主梁選型的合理性對(duì)工程的經(jīng)濟(jì)性有重大影響。主梁可選用鋼梁、鋼與混凝土組合梁、型鋼混凝土梁和普通鋼筋混凝土梁等形式。本文結(jié)合某工程剛接框架主梁的選型，分別按四種類型進(jìn)行主梁設(shè)計(jì)，并對(duì)經(jīng)濟(jì)性和力學(xué)性能進(jìn)行對(duì)比分析，提出設(shè)計(jì)建議。
