The report concerns the potential use of steel subframes and composite panels in the overcladding of existing concrete or masonry buildings. The initial investigations concentrated on a review of existing overcladding systems, and the advantages of a steel-intensive overcladding system spanning directly between the floors of an existing concrete building. The testing phase of the project covered tests on the structural interaction between the subframe and the fixings to the existing structure, and tests on the structural behaviour of complete panels and subframes. The latter tests comprised the following parameters: number of fixings, types of subframe members, and panels with or without window openings. The loads were applied by airbags as a simulated wind suction (negative pressure). Failure loads were well in excess of extreme wind pressures, indicating that the system is structurally acceptable. Importantly, the system possessed a sufficient factor of safety in the event of one fixing failing. Details of the proposed overcladding system are included in this report.
