Prediction of wind-induced failure of loose laid roof cladding systems

Abstract This paper presents a correlation for predicting wind speeds at which loose-laid insulation boards or paving slabs are dislodged from roofing systems on flat roofs. The correlation is based on experimental data obtained from 1:10 scale model tests in a 9 m × 9 m wind tunnel. The influence of building shape, parapet height, weight per unit area of boards or paving slabs and interlocking effects are accounted for.
