［摘要］建筑结构所用销轴由于其构造简单、传力明确、外形美观等原因，被广泛应用于空间结构支座及连接节点设计中，但关于销轴的设计国内尚无统一的标准，针对销轴连接的力学研究也较少。在国内外研究的基础上，给出了销轴的设计原则和材料强度设计值的选取，并提出了建筑结构所用销轴的分析模型，推导了相关的设计公式。最后给出了一具体工程实例，可为类似工程提供参考。

Abstract:Pin connection in building structure is widely used in the design of spatial structure bearing and connection joint， because it has simple construction, clear load transferring and beautiful appearance. However, there is no uniform domestic standard in the design of pin connection, and the mechanical research about pin connection is also rare. Design principle and determination of material strength design value of pin connection were proposed based on the research from both home and abroad. The analysis model of the pin connection for building structure was put forward, and the relevant design formulas were deduced. At last, a practical engineering example was given, which could provide reference for similar projects.

Keywords:building structure; pin connection; design strength; design method
