［摘要］以國內(nèi)的兩座鑄鋼結(jié)構(gòu)為背景，從建筑結(jié)構(gòu)角度出發(fā)，基于有限元分析，結(jié)合我國現(xiàn)行的CECS規(guī)程《鑄鋼節(jié)點(diǎn)應(yīng)用技術(shù)規(guī)程》（CECS 235∶2008），以及在編的JGJ規(guī)程《鑄鋼結(jié)構(gòu)技術(shù)規(guī)程》，通過流程圖從幾何造型設(shè)計(jì)、工藝設(shè)計(jì)和力學(xué)性能分析和校核計(jì)算三方面總結(jié)了鑄鋼結(jié)構(gòu)設(shè)計(jì)方法。將流程圖展開，從結(jié)構(gòu)設(shè)計(jì)角度對(duì)鑄鋼結(jié)構(gòu)的設(shè)計(jì)進(jìn)行了詳細(xì)分析。所總結(jié)的鑄鋼結(jié)構(gòu)設(shè)計(jì)方法可以滿足鑄鋼結(jié)構(gòu)的設(shè)計(jì)要求，且為在編的JGJ規(guī)程《鑄鋼結(jié)構(gòu)技術(shù)規(guī)程》的編制提供了依據(jù)。［關(guān)鍵詞］鑄鋼; 鑄鋼件; 鑄鋼節(jié)點(diǎn); 鑄鋼構(gòu)件; 鑄鋼結(jié)構(gòu)中圖分類號(hào)：TU392.6 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)07-0044-08
Design and application of cast steel structureYang Yuan1, Chen Zhihua1, Ma Kejian1, 2, Wang Xiaodun1(1 School of Civil Engineering, Tianjin University, Tianjin 300072, China; 2 Space Structure Research Center, Guizhou University, Guiyang 550003, China)Abstract: Based on two domesticcast steel structures and the finite element analysis, with theperspective of building structure, combined with the current CECS specification: Technical specification for application of connections of structural steel casting（CECS 235∶2008）and the compiled JGJ specification: Technical specification for cast steel structure, cast steel structure design method was summarized by flowchartfrom the geometric modeling design, process design, mechanical analysis and checking calculation. Unfolding the flow chart, the design of cast steel structure was analyzed in detail from the structure design point. The summarized design method can satisfy the need of cast steel design, and it also support the compiled JGJ specification: Technical specification for cast steel structure.Keywords: cast steel; steel casting; cast steel joint; cast steel component; cast steel structure
