Prestressed Channel Section Masonry Walls

The prestressed channel section is a further development of structural masonry by the authors’ practice and stems from earlier innovations. The concept originated from a variation in fin walls’ which are basically a series of connected T-sections. On one contract, in order to provide floor to roof glazing, it was necessary to eliminate alternate panel sections between the fins. The remaining section was treated as connected L-beams (see Fig 1). It was realised, with hindsight, that it would have been better designed as channel sections. G. Shaw, W.G. Curtin, C.L. Priestly and G.J. Othick
