The methods of overcoming the problem of high diagonal tension stresses in flat plate construction are: (1) to change the building dimensions or the concrete strength or both, (2) to use grillages, (3) to use a reinforcement system made from ordinary reinforcing bars. An increase in the concrete strength is the most economical method but does not permit the diagonal tension stress to be increased by more than 33 percent. The second method is about eight times as costly as the increase in concrete strength and about four times as costly as the third method. The second method has been certified by building codes. The third method is the subject of this thesis.[...]
