Thickness Of Concrete Roof Slab

Exact specifications vary but most concrete roofs are several inches thick.

Thickness of concrete roof slab.

A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Below is a comparison table between the two most common thickness used in the construction industry. If reinforced concrete were to be reused strong connections would have to be made between roof and walls. In general 6 inch 150mm slab thickness is considered for residential and commercial buildings with reinforcement details as per design.

Slab on ground 1 4 minimum thickness of diaphragms. Concrete thickness for flatwork such as slabs on grade and driveways a minimum thickness of four inches is required but increasing the thickness to five inches can add nearly 50 percent to the load bearing capacity. For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers. Methods used for finding slab thickness varies for different types of slabs.

A concrete roof is exactly what it sounds like. The most commonly lightweight precast wall panel used are 75mm thick and 100mm thick. Vpanel has a wide range of thickness that caters to different specification and technical requirements from 75mm thick to 200mm thick. 1 3 minimum thickness of slab on the ground ubc recommends minimum thickness of concrete floor slabs supported directly on the ground to be 89mm whereas bcgbc4010a apply structural principles to residential low rise constructions determined minimum thickness to be 100mm.

Reinforced concrete slabs are heavier and generate higher seismic forces in an event. Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses.
