Retrofitting of RC panels subjected to blast effects using elastomeric polymer coatings

Abstract

This paper presents the findings from the experimental programme and Finite Element (FE) analysis performed to study the behaviour of polyurea coated RC panels subjected to blast effects. The overall findings of the research, including detailed experimental findings of three of the tested panels (one un-retrofitted and two polyurea coated panels), and the subsequent FE analysis performed to simulate the blast trials, are discussed in this paper. All 3 panels had dimensions of 1700 (L) x 1000 (W) x 60 (T) mm. Among the retrofitted panels, one panel was subjected to a 4mm polyurea coating on the non-blast facing face, whereas the other was coated with a 4 mm polyurea coating on both faces. All..
