Design charts for optimal design of T-beam floors

Abstract

Mathematical programming techniques have been used to minimize the cost of T-beam floors. One-way continous slabs and simply supported T-beams have been designed by the limit state approach in accordance with CP 110-1972 using M25 grade concrete and cold worked high yield reinforcement. Cost of one of the bays has been minimized using the DFP algorithm. Parametric studies have been carried out for various span ratios, cost ratios of materials and magnitudes of imposed loads. Use of the design charts developed has been explained. 1981.
