Abstract

The equipment of French nuclear power plants is fixed on reinforced concrete structures with base plates with headed fasteners. Electricity of France decided to carry out an experimental research program in partnership with Laboratory of Civil and Environmental Engineering in order to optimize the design of the headed fasteners and identify margin. This article introduces the results of static tension tests on an anchorage composed of an anchor plate welded to four ribbed bars or headed smooth studs. The anchors are cast in place in a reinforced concrete block. The experimental campaign is carried out on real size anchors and anchors with reduced embedment depths. Tests on single rod are also carried out in order to analyse the group effects. Following the embedment depth, the collapse of the anchorages is caused by a concrete cone breakout failure, a steel rod failure or a combination failure of bond and concrete cone failure for ribbed bar. For bonded anchors, the group effect involves a decreasing of 30 % of the bond stress. For headed anchors, Eurocode 2 tends to underestimate the ultimate strength for a concrete breakout failure. This experimental campaign will provide a data base enabling the development of numerical models in order to improve the design.
