[摘要］支座作為結(jié)構(gòu)的重要傳力構(gòu)件，選擇安全、實(shí)用的支座節(jié)點(diǎn)是結(jié)構(gòu)設(shè)計(jì)的關(guān)鍵。對(duì)青島北站的拱腳支座節(jié)點(diǎn)進(jìn)行了有限元分析。由于青島北站的拱腳支座節(jié)點(diǎn)復(fù)雜，目前對(duì)這種復(fù)雜的異形截面鋼柱腳的承載力還未有明確的計(jì)算依據(jù)，因此在分析的過程中對(duì)有限元分析的方法和假定進(jìn)行了討論。分析結(jié)果表明青島北站的拱腳支座節(jié)點(diǎn)的設(shè)計(jì)安全可靠，在各種荷載工況下可以安全有效地發(fā)揮作用，為同類大跨空間結(jié)構(gòu)的支座節(jié)點(diǎn)設(shè)計(jì)與計(jì)算提供了參考。

Abstract：As support joints are important bearing structure transmission members, choose a safe and practical support joints is a key point of structural design. An arch support joint of Qingdao North Station was analyzed by finite element. Since Qingdao North Station arch support joints are very complex, and this complex and irregular support joints do not have a clear basis for calculation, so during the analysis process, the finite element method and assumptions were discussed. The results show that Qingdao North Station arch support joints design is safe and reliable under a variety of load cases. Areference was provided for the similar span space structures.

Keywords：Qingdao North Station; space structure; support joint; finite element method; ABAQUS
