COMPOSITE JOINT FOR BUILDINGS PLACED IN SEISMIC AREAS THEORETICAL AND EXPERIMENTAL STUDIES
The design of composite structures for buildings placed in seismic areas deals with some special provisions, aiming to satisfy the design concept for earthquake loads.The inelastic deformations must be concentrated in predefined zones, preferably outside of the joints, in order to dissipate the seismic energy. Therefore, theoretical approaches complemented with an experimental testing program were developed at the Politehnica University of Timisoara for a specific steel-concrete composite joint,used into a multi-storey skeletal structure. Special testing specimens were design both for the structural steel and the composite joint. The calibration of the experimental specimens was performed in the elastic and post-elastic range using numerical analysis. The main objective of the studies was to observe and evaluate the behaviour and the failure mode for steel and composite joint. Two load hypotheses on the joint were considered: symmetrical and asymmetrical.The paper contains a comparative study between the experimental results obtained on the behaviour of the structural steel and steel-concrete composite joint.
