Allwall Clay Brick Plate Test


Tests were carried out on Allwall Integral Masonry System walls in order to establish their behaviour when working as a bi-directionally stressed plate and to establish whether the test results would exceed the design stresses.  The tested enclosure panel forms the basic component of the Alpha (self-bearing) and Beta (semi-supported) Allwall enclosure walls.  The data obtained are also valid for the Gamma (Hanging) and Omega (Curtain) walls.  Interactions between the universal Allwall Ladriflor clay bricks, Maresa M-80 mortar, Murfor horizontal truss-type reinforcements, and the Allwall Rib double wire vertical ribs were observed.  Horizontal flexural strength tests were carried out using a  specially designed triangular space frame structure.  It was  found that the wall behaved in the manner of a bidirectionally reinforced slab or plate.  Failure occurred,  as predicted, in the centre of the longest tension reinforcement. Different values of ultimate stress between the second and fourth Murfor reinforcement (5 reinforcements  in all) were clearly shown. Greater deformation in the upper  area compared to the lower area of the brickwork was probably due to the influence of the continuous lower support.  1 ref.
