OBJECTIVE/SCOPE • To define and introduce beam-to-column joints; • To introduce composite Frames; • To describe their behavior; • Summary of Configuration Detailing of joints
8.1 Introduction A continuous beam in a building may be interrupted by its supporting internal columns;and these members are usually part of a framed structure.By definition,composite frame is a framed structure in which some or all of the elements are composite members and most of the remainder are structural steel members. Composite joint is a joint between a composite member and another composite,steel,or reinforced concrete member,in which reinforcement is taken into account in design for the resistance and the stiffness of the joint

The type of beam-to-column joints used influences the global analysis of all the members in their vicinity. Beam-to-column joints are classified both by stiffness and by strength.The categories are: For stiffness:rigid,semi-rigid,and nominally pinned; > For strength:full-strength,partial-strength,and nominally pinned

Composite flush end plate connections Flush end plate connection: One popular types used in construction,in which the end plate is usually welded to the beam before being bolted to the column section on-site.
