Steel Designers' Manual - 6th Edition (2003)
26.4 Summary
The successful performance of every structural steel frame is dependent as much
on its connections as on the size of its structural members. Bolted connections and
in particular moment connections are complex in their behaviour. The distribution
of the stresses and forces within the connection depends on both the capacity of the
welds, bolts etc and on the relative ductility of the connected parts. It is therefore
necessary for the design of connections to be consistent with the designer’s assumptions
regarding the structural behaviour of the steel frame. When choosing and proportioning
connections the engineer should always consider the basic requirements
such as the stiffness/flexibility of the connection, strength and the required rotational
capacity. The design philosophy presented in this chapter together with the
detailed design checks provide the engineer with a basic set of tools that can be
used to design connections which are better able to meet the design assumptions.
To aid the designer further this chapter concludes with a set of worked examples
for simple connections.
