[摘要］支座作为结构的重要传力构件，选择安全、实用的支座节点是结构设计的关键。对青岛北站的拱脚支座节点进行了有限元分析。由于青岛北站的拱脚支座节点复杂，目前对这种复杂的异形截面钢柱脚的承载力还未有明确的计算依据，因此在分析的过程中对有限元分析的方法和假定进行了讨论。分析结果表明青岛北站的拱脚支座节点的设计安全可靠，在各种荷载工况下可以安全有效地发挥作用，为同类大跨空间结构的支座节点设计与计算提供了参考。

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
