The required strength of the steel connections is determined by structural analysis for the specified design loads, or the requirements of AISC Seismic Provisions Standart.
Connections can be classified into three categories:
The classification according to moment strength is grouped under 3 sections: full strength, partial strength, and hinge.
According to rotational rigidity, it is divided into 3, which are rigid, semi-rigid, and hinged.
According to the rotational capacity, it is classified as highly and moderately ductile.
The design rules related to moment-resisting and hinged connections are explained in the relevant sub-sections.
