Proper design of falls in reinforced concrete flat roofs is most important in creating flow paths to suitable discharge points.
Reinforced concrete flat roof detail.
One of the most crucial step in building a flat concrete roof is to figure out the size of the concrete block you will need.
The effects on the building physics functions must be.
Exact specifications vary but most concrete roofs are several inches thick.
Step 3 placing the steel joists.
The steel joists will provide a strong foundation for the flat concrete roofing.
Contemporary designers frequently aim to produce the same clear and simplified forms that appeared at the beginning of the 20th century but are now free to use a wide range of new materials and construction techniques that reflect present day technology.
According to the 1995 aci code all two way reinforced concrete slab systems including edge supported slabs flat slabs and flat plates are to be analyzed and designed according to one unified method such as direct design method and equivalent frame method.
For a roof to be effective surface water should be discharged quickly without ponding or stagnation.
For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.
As the roof is constantly exposed to direct.
The blocks come in several sizes but this guide will assume you are using a 16 3 4 inch wide concrete slab.
I ii stability strength.
The roof should incorporate insulation and usually a vapour control layer to protect from interstitial condensation.

However the complexity of the generalized approach.
A concrete slab flat roof is normally made up of a structural layer of concrete finished with a smooth screed onto which a water proof layer such as a membrane is laid.
Flat roofs with the waterproofing above the insulation inverted roofs and impermeable concrete slabs are all suitable for use as green roofs.
Beneath the roof cover structural concrete roof decks are commonly topside insulated using adhered insulation panels or cast in place lightweight insulating concrete.
Iii durability iv fire resistance v thermal properties.
Reinforced concrete flat roof.
Next it is important to select the appropriate waterproofing membrane.
Iii suitable for large ang tall building.
Definition i roof platform which is either horizontal or inclined up to 10 degrees to prevent ponding ii usually sorrounded by fascia parapet wall.
Today flat roofs are used by architects for the same reasons that they became a cornerstone of modernist architecture.
