§ 钢结构的连接
(steel connections )
钢结构(steel structure)—由钢板(steel plate)或各类型钢(steel section)通过必要的连接(connection)组成构件(如梁(beam)、柱(column)、桁架(truss)等),再通过一定的安装连接(installation and erection)而形成的整体结构物。

连接的重要性(the importance of connection):
是钢结构的细部(detail),易引起应力集中(stress concentration)或局部应力(local stress);
对节点连接(connection)的细部构造(constructural details)认识相对粗糙;
构造设计不恰当,易引起事故。
连接恰如人体的关节(knuckle)。

钢结构连接的分类(classification):
按制作与加工的地点分(loaction,manufactured and machined):
工厂连接和工地连接(in factory and on site);
按采用的材料技术分:
销钉(pin bolt)、铆钉(rivett)、螺栓(bolt)、焊接(weld)及紧固件连接(fastener)。
钢结构连接的设计原则(principles of design):
安全可靠(safe and reliability)、
