［摘要］針對(duì)不銹鋼焊接連接，對(duì)比了歐洲規(guī)范BS EN1993-1-4∶2006、美國(guó)不銹鋼結(jié)構(gòu)設(shè)計(jì)指南和美國(guó)規(guī)范SEI/ASCE 8-02及中國(guó)規(guī)范的適用范圍、設(shè)計(jì)方法，研究了各規(guī)范對(duì)不銹鋼對(duì)接焊縫、角焊縫連接設(shè)計(jì)的基本規(guī)定和設(shè)計(jì)計(jì)算方法。分析結(jié)果表明，中國(guó)規(guī)范的焊縫強(qiáng)度取值與歐洲規(guī)范BS EN1993-1-4∶2006相近，美國(guó)規(guī)范SEI/ASCE 8－02對(duì)于側(cè)面角焊縫或斜向角焊縫比中國(guó)規(guī)范和歐洲規(guī)范BS EN1993-1-4的安全儲(chǔ)備更高。中國(guó)規(guī)范對(duì)于焊接連接設(shè)計(jì)的規(guī)定總體是合理的。［關(guān)鍵詞］不銹鋼; 對(duì)接焊縫; 角焊縫; 焊接連接; 設(shè)計(jì)方法; 規(guī)范對(duì)比中圖分類號(hào)：TU391 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)15-0001-04
Comparative study on stainless steel weld connection design method in European, American and Chinese design codesWu Yaohua, Qiu Shengguang, Zhang Yu（Central Research Institute of Building and Construction, MCC, Beijing 100088, China）Abstract: For stainless steel weld connections, the applicable scopes and design methods of European code BS EN1993-1-4∶2006, American stainless steel structure design guidelines and American code SEI/ASCE 8-02 and Chinese code were compared. The basic regulations and design calculation methods of stainless steel butt weld and fillet weld connection design in above codes were studied. Analyses results show that the weld strength value in Chinese code is similar to that in European Standard BS EN1993-1-4∶2006. The safety reserve of side fillet weld or oblique fillet weld in American Standard SEI/ASCE 8-02 is higher than that in Chinese code and European code BS EN1993-1-4. The requirements of Chinese code on weld connection design are generally reasonable.Keywords:stainless steel; butt weld; fillet weld; weld connection; design method; code comparison
