Reinforced Concrete Roof Slab Thickness

Reinforced concrete slabs are heavier and generate higher seismic forces in an event.

Reinforced concrete roof slab thickness.

Plan view of a reinforced concrete pitched inclined slab. If reinforced concrete were to be reused strong connections would have to be made between roof and walls. Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete.

The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration. A solid slab of concrete capping the top of your house. Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses. Exact specifications vary but most concrete roofs are several inches thick.

For determining moments shears and reactions of such slabs. Design process includes proper assumption of structural element sizes and then check hellip. The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers.

Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure. 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. Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars. The diameter of bar generally used in slabs are.

Slab reinforcement cantilever reinforcement slab thickness roof apex reinforcement example of a 1. A concrete roof is exactly what it sounds like. Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes.
