7.1介绍
结构钢构件的连接至关重要。 一个不正确的连接，可能是一个结构中的“薄 弱环节”，一直是无数失败的原因。 结构构件的失效很少; 大多数结构性故 障是设计不当或错误连接的结果。 由于连接设计的责任有时存在混淆，使问 题更加复杂化。 在许多情况下，连接不是由设计结构及其余部分的同一个工程 师设计的，而是由与为该项目提供材料的钢结构制造商有关的人员设计的。然 而，负责生成设计图纸的结构工程师负责完整的设计，包括连接。 因此，工 程师有责任精通连接设计，只是为了验证其他人设计的连接

INTRODUCTION
Connections of structural steel members are of critical importance. An inadequate connection, which can be the “weak link” in a structure, has been the cause of numer- ous failures. Failure of structural members is rare; most structural failures are the result of poorly designed or detailed connections. The problem is compounded by the con- fusion that sometimes exists regarding responsibility for the design of connections. In many cases, the connections are not designed by the same engineer who designs the rest of the structure, but by someone associated with the steel fabricator who fur- nishes the material for the project. The structural engineer responsible for the pro- duction of the design drawings, however, is responsible for the complete design, including the connections. It is therefore incumbent upon the engineer to be proficient in connection design, if only for the purpose of validating a connection designed by someone else.
