The project dealt with monolithic reinforced concrete slab of apartment building which was carrying in one direction. it where proposed alternatives of construction system. Finally it selected system of one way slab as the most suitable option. Empirically derived formulas to calculate the dimensions of individual elements of design . The column was desugned on the basis of resistance in centrc pressure. Reinforcement in the slab has been designed and assessed by the trust and wall-platemodel. He was subsquently verified by the second limit state of serviceability as crack width and deflaction of nonlunear creep.
