Experimental Tests Concerning the Behaviour of the Steel-Concrete Composite Joints
Abstract
The design of the building structures situated in a seismic area deals with some spe¬cial provisions in order to satisfy the design concept for earthquake loads. Thus, some inelastic deformations must be concentrated in predefined zones for seismic energy dissi¬pation. Therefore, it is important to evaluate correctly the load bearing capacity of each basic structural element, such as beams, columns and joints too. At the "Politehnica" University of Timisoara, it was developed an experimental test program for a specific steel and composite (steel-concrete) joint. Two load hypotheses were considered in order to simulate the permanent loads and the horizontal (seismic) loads, respectively, acting on the structure and the corresponding joints. Two series of joints were tested in laboratory for monotonous and cyclic behavior. Both the steel and the steel-concrete joints were studied. A comparative study between the steel and the steel-concrete composite joints is presented.
