The development of the high tensile steel cable has made it possible. Cable roof have a wide field of application and have been used to cover such differing buildings as stadia and sports hall, swimming pools and water reservoirs, concert halls and theatres, hangers, warehouses and factories. With the increase in the demand of suspended cable roof system, theoretical research work in the field of analysis of them has also increased, though the analysis of a cable structure is quite complex, advent of electronic digital computer enable to make detailed study of them. The main aim of the present work is to investigate the behaviour of cable Suspended roofs under static loads. Cable roofs have been analysed as a discrete system by mean of stiffness method, using an already available computer programme after necessary modifications. Influence of different parameters, such as level of pretension, area of crosssection of cables on maximum deflection, maximum member force and maximum change in member force has been studied. The results are used to investigate the factors that affect the response and design of cable suspended roofs. Also these results are presented in the form of X-Y graphs plotted using non-dimensional parameters. Recommendations are given regarding selection of number of cables, area of cross-section and force of pretension for design of cable net roof and to cover circular plan area.ennullThesis
