Elevated concrete floor slab design.

An elevated or suspended concrete slab is most commonly found in multistory heavy use buildings such as parking garages or commercial offices. While this sounds easy the trick is to determine the amount of beam camber upward deflection that will offset the deflection from the dead weight of the. Deflection of form w o r. Effects of concrete placing and fin ishing operations on floor flatness will be discussed in a subsequent a rt i c l e.

Many designers believe that cambering the beams is the key to achieving a nearly level floor. Design and construction methods on slab levelness and elevation con t r ol during and after constru c t i o n. Many factors need to be taken into account when designing an elevated concrete floor not only to take into account the weight of the floor but also the effect of additional loads on the concrete. The main problem with using post tension slab is that if care is not taken while making it it can lead to future mishaps.

Base floor slab waterproof system a typical base floor slab where the design criteria include controlling moisture migration and water vapor transmission into the interior space can be referred to as a waterproof. The concrete floor slab itself provides structural support for floor loads and suitable backup for floor coverings and finishes.
