AN INNOVATIVE MONO-FASTENER ANCHOR PLATE FOR APPLICATIONS IN SEISMIC ZONES

In Nuclear Power Plants (NPPs) equipment is commonly fastened to reinforced con-crete structures by anchoring plates. They provide a flat surface in which steel supports may be welded. Typical solutions imply minimum four studs, thus complicating the installation where high density of reinforcement. A new specific steel-to-concrete connection with only one fas-tener is investigated in this paper. This solution is capable to resist tensile and shear forces with and without eccentricity. Since in both Eurocodes 2 and 4 there is a lack of information about the assessment of anchor plates under seismic action, existing European protocols for post-installed anchors in “widely” cracked were adapted.
