  Costes



The floor system is typically the costliest structural element in any given building and for low-rise buildings with few floors, the floor system represents the majority of the structural cost. As the number of floors increase, the cost of foundations, vertical elements carrying gravity loads, and lateral load-resisting systems become a larger percentage of the total structural cost. However, even in tall buildings, the cost of the floor system often dominates the economics for the structure...
