Brick demonstrates its leading edge structural capabilities

'Off-the-frame' structural brickwork can result in significant structural, aesthetic and cost benefits when compared to conventional multi-story cavity wall construction, according to the Brick Development Association (BDA).

These are the findings from 'Off the Frame Brickwork: Analysis of the Data from Winterton House' - a recent paper on an award winning 25-storey steel frame tower block that was recently refurbished with an innovative form of brickwork construction.

"Rather than demolish the original structure it was more economical to re-clad with brickwork to provide the sort of structural strengthening that non-brick materials could not provide. The result is a leading edge, hybrid construction that utilises both frame and brickwork and can be applied to new build with the same economies and benefits," said the BDA.

The use of self-supporting, vertically restrained, off-the-frame 215mm clay brickwork avoided the need for stainless steel support angles and major structural strengthening.

"Compared to conventional 102mm brickwork supported on angles, the thicker brickwork involved with this technique provides greater scope for architectural variation," said the BDA.

"It also provides additional whole life cost savings as the need to regularly reseal horizontal movement joints beneath support angles is eliminated. From an environmental viewpoint, it has extended the life of the building by 60-80 years."
