There (1)… diagonal bracing in the plane of the roof and in one of the planes formed by the web members of the roof trusses. The principal truss spanning 7.35m has members in (2)… separate vertical planes so that the members overlap. The brickwork (3)… give the required scale to the building, (4)… the enclosure, take gravity loads and act as shear walls against horizontal (5)… . The tensile stresses that develop in shear walls (6)… wind or other horizontal forces must be balanced by the gravity loads as in all loadbearing masonry structures. However, in (7)… buildings, such as this, the tensile stresses due to wind are extremely (8)… . Timber with a high strength to weight (9)… is the best choice of material for the roof construction. The (10)… period for construction was 21 months.
