Non-Linear Seismic Behavior of Concrete Beam - Column Connections

A parametrik investigation was conducted to study the non-linear behavior of
precast and cast-in-place reinforced concrete beam-column connections subjected to TABAS seismic forces (1979).
The behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. Calculation results indicated that in the cast-in-place connections the maximum principal stresses, located at the vicinity of the joint core. At this location,the most critical stress was tensile.
In the case of precast reinforced concrete beam-column connections the results showed that the maximum principal stress occured at the joint core interior and the tensile stress at this section was more than of other parties of joint.
