This presentation is prepared using:•Structural Steel Design by McCormac and Csernak 2012

•AISC Manul 13th ed (14th )

There are three types of Beam-Column Connection

• Rigid : Able to transfer Shear and Moment

• Simple: Provides for Shear but NOT Moment

• Semi-Rigid: Some of the Moment and ALL Shear
