This thesis presents the results of a study into the behaviour of post-tensioned pocket type brickwork retaining walls. An analytical and experimental study was carried out to examine the behaviour of the wall up to failure. The programme of work considered the effect of the following parameters on the perfromance of the wall: (i) vertical concentrated eccentric load; (ii) percentage area of steel; (iii) pocket spacing and wall slenderness; (iv) type of wall bond. The results of the analyses were compared with those based on the Code of Practice, B.S 5628, Part 2, 1985. A computer program was written in Fortran to predict the ultimate moment of the wall panels, using predicted equilibrium equations. Good agreement was found between the theoretical and experimental results. The results show that post-tensioned pocket type brickwork retaining walls have a large nominal strength, largely due to the presence of prestressing forces and the behaviour of the walls as homogenous cantilevers. The most effective pocket spacing was found to be h/3, and the maximum spacing should be limited to give an aspect ratio which is greater than 1.15. The study confirms the applicability of prestressed brick masonry for structures such as slabs and retaining walls irrespective of the type of brickwork bond.
