Abstract:

A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures include diagonal bracing systems. The connection detail between the structural steel and reinforced concrete strongly influences the response and the effectiveness of the strengthening program. In this investigation the load-deflection characteristics and behavior of connections between existing concrete and steel elements loaded in tension were evaluated. Anchors epoxy grouted into a concrete block simulating a column transferred shear between the elements.
