The thesis comprises of 44 published papers mainly dealing with various aspects of structural masonry. The success of masonry and its use in high-rise buildings and other civil engineering works required better understanding of materials and its structural behaviour. The thesis describes the most comprehensive and systematic research investigation undertaken in the area of material science relevant to structure, structural performance and design methodology for plain, reinforced and prestressed masonry. Novel test methods for obtaining tensile strength of individual brick and bi-axial strength of masonry in flexure are described. Several series of full-scale tests to investigate the behaviours of brickwork subjected to combined compression and shear, multi-storey brick shear wall structure subjected to wind loading, progressive collapse, lateral strength of wall panels with and without precompression, interaction between wall and floor slabs are also described. Based on the tests of real structures, design methods for multi-storey masonry structures subjected to vertical and wind loading, and to limit the progressive collapse due to accidental loading are recommended. A Coulomb type of equation is suggested to calculate the ultimate shear strength of masonry. A theory to predict the lateral strength of masonry subjected to precompression has also been described. Methods developed to predict the shear and flexural strengths of reinforced and prestressed masonry are elucidated. A plastic method, similar to concrete, is used for the theoretical prediction of the shear strength of prestressed beams. An analytical technique for calculating the load-deflection and the ultimate moment capacity of reinforced and prestressed sections is also presented. The technique takes into account all the sources of non-linearity; such as non-linear material behaviour, cracking and tension stiffening.
