STRUCTURE WORKS
Both live and dead loads are supported by the floor system that transfers these loads to beams and columns or load bearing walls. Structural steel or concrete framing are the most commonly used structure systems. Concrete structures require formwork and shoring to shape and support fresh concrete until it cures and can support itself. Optimal temperature and moisture conditions are to be kept during the time that concrete is cured. In case of inappropiate weather conditions, concrete must be protected with plastic membranes or by using additives. To avoid possible airspaces, fresh concrete must be vibrated during its' poured pouring. Reinforcing bars serve as tensile (and compressive when needed) reinforcement. Longitudinal bars, stirrups and lateral ties distribution must respect{have?} a minimum concrete covering to protect steel from corrosion. The quantity, diameter, length, shape and separation between steel components is defined by a qualified structural engineer. Steel structures assembly is faster than concrete structures assembly, however, fire-resistive coatings are required because steel can lose strength rapidly in a fire.
