Flat Slab Floor System Definition

The ff117 fl110 floor profile on the right exhibits the typical flatness levelness of a super flat floor.

Flat slab floor system definition.

A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. A flat slab is a two way reinforced concrete slab that usually does not have beams and girders and the loads are transferred directly to the supporting concrete columns. The name waffle comes from the grid pattern created by the reinforcing ribs. Beam supported slab definition.

The ff30 fl20 floor on the left is a moderately flat random traffic floor tolerance. The special fmin system of tolerance definition and measurement requires that any defects in excess of the maximum allowable variation be. A waffle slab or two way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. The flat plate floor system is a common floor construction type employed in the construction of the building.

A flat plate floor system is a reinforced concrete frame system with a uniform thickness that is supported directly over the columns or the load bearing walls. Flat slab floor system. Definition description civil engineering. A flat slab is a one way or two way system with thickenings in the slab at the columns and load bearing walls called drop panels figure 9.

They increase the shear capacity and the stiffness of the floor system under vertical loads thus increasing the economical span range. For more detailed definition. The important features construction and the advantages of employing a flat. Drop panels act as t beams over the supports.

The main difference between flat slab conventional slab beam system is that the one is directly supported on the column while another system has a beam for support. Advantages of flat slab. In other words when the loads or spans or both become quite large the slab thickness and column sizes required for flat plates or flat slabs are of such magnitude that it is. The load is transferred directly from slab to column in the flat slab.

In conventional slab beam system the load is transferred from slab to beam and ultimately beam to the column. Waffle slabs are preferred for spans greater than 40 feet 12 m as they are much stronger than flat slabs flat slabs with drop panels two way slabs one way slabs and. A two way slab with beams is a type of floor system is obviously used where its cost is less than the costs of flat plates or flat slabs. The flat plate is a two way reinforced concrete framing system utilizing a slab of uniform thickness the simplest of structural shapes.

A flat slab is a two way reinforced concrete slab system that doesn t have beams or girders and the loads are transferred directly to the supporting columns. A flat plate is a one or two way system usually supported directly on columns or load bearing walls. Flat plate system introduction.
