Previous building fires and research has shown that simple (shear) connections develop large axial force and flexural demands during a fire leading to potential failure of the connections and progressive collapse of a building. These findings have motivated decades of international research on the fire behavior of simple (shear) connections. While this research all confirmed that simple connections experience large axial force and flexural demands, it occurred without consistency of testing methodology, testing setup, and reporting of results. Due to this inconsistency, the decades of research have yet to be synthesized into comprehensive code changes for the design of simple connections in fires. This paper will summarize international experimental and numerical research on simple (shear) connections and highlight the inconsistencies between this research in an effort to motivate consistent testing and data reporting for future research developments.

先前的建筑火灾和研究表明，简单（剪切）连接在火灾期间会产生巨大的轴向力和弯曲需求，导致连接潜在失效和建筑物逐渐倒塌。这些发现推动了国际上数十年对简单（剪切）连接的火灾行为的研究。虽然这项研究都证实简单的连接会经历较大的轴向力和弯曲需求，但测试方法、测试设置和结果报告的一致性并不高。由于这种不一致，数十年的研究尚未综合成火灾中简单连接设计的全面代码更改。本文将总结国际上关于简单（剪切）连接的实验和数值研究，并强调这些研究之间的不一致之处，以促进未来研究发展的一致测试和数据报告。
