This section provides information and resources related to design of precast concrete systems as well as integration of precast with other systems.
Precast concrete floor construction details.
In precast concrete construction majority of structural members are manufactured in manufacturing plants away from the construction site.
For the beams and double tees the capacities are somewhat independent of the available fire rating.
The material properties used are 6000 psi concrete in the precast element and either 250 ksi or 270 ksi prestressing strands.
Here are some of the design and installation details of the precast concrete planks.
When you specify an easi span building with a floor it is an all concrete solution.
The joints between the units are grouted with in situ concrete and a concrete structural topping is provided for some applications.
The precast concrete floor unit is used to span between supporting steel beams as an alternative to in situ concrete and metal decking.
It provides flexibility during the installation process and requires minimal site.
Precast concrete construction system has its own characteristics which influence the layout span length construction depth and stability system to a great extent.
The floor panel is comprised of a topping or deck supported by a number of parallel longitudinal concrete stems that extend along the length of the panel.
The concrete stems extending between the end blocks are spaced 2 ft on center.

However for the spancrete hollowcore plank the fire endurance provided will have an effect on load capacity.
