Experimental Tests of Steel Unstiffened Double Side Joints with Flush and Extended End Plate
Experimental tests of steel unstiffened double side bolted end-plate joints have been presented. The main aim of the conducted tests was to check the behavior of joints in an accidental situation and possibility of creating secondary mechanism, i.e. catenary action in the scenario of column loss.
