Page V not included in the thesis. / <p> This project report includes classification of a design of high-rise buildings. Then the survey of recent optimisation techniques is made. The optimum design of one-way flab, beam and girder slab is presented. Also optimum design of flat plate is presented as both problems are part of overall optimum design of high-rise buildings.</p> <p> The project report also describes the development of the computer programs for optimum design of one-way slab and flat plate. The behaviour of cost function in vicinity of optimum solution is presented and comparison of conventional versus optimized design method is made.</p> / Thesis / Master of Engineering (MEngr)
