Punching shear behaviour of interior slab-column connections strengthened by steel angle plates

The present paper is concerned with a series of tests on reinforced concrete flat slabs to examine the behaviour of interior slab-column connections employing steel angle plates and high strength bolts as strengthening elements. The angle plates were bolted to the column faces and slab at both tension and compression sides. The shorter leg of the angle plate attached to the column face acts as a column capital of an equivalent concrete width...
