Structural Floor One Way Ribbed Slab

T beams are known as joists which are formed by setting steel pan at a constant spacing.

Structural floor one way ribbed slab.

One way ribbed slab system. 763 3 comparison between the results of finite element method and traditional method two bays one way ribbed slab is analyzed by both traditional and finite element methods to determine the induced moments of the rib. Mathematical structural analysis of one way. One way spanning slabs.

The ribs are usually tapered and are uniformly spaced at distances that do not exceed 750mm. Ribbed slabs are slabs cast integrally with a series of closely spaced joist which in turn are supported by a set of beams. One way joist slab ribbed slab it consists of a floor slab usually 50 to 100mm thick supported by reinforced concrete ribs or joists. The service live load is 100 psf and 4000 psi concrete is specified for use with steel with a yield stress equal to 60000 psi.

Ribbed waffle slab system. Depending on the boundary condition and the properties of the slabs methods of finding bending moment is expressed in the bs 8110 part 01 as follows. A one way joist floor slab consists of a series of small reinforced concrete t beams that are connected with girders that in turn carried by the building column. This brief will provide guidance to architects and structural engineers during the concept phase of the design for selecting a suitable one way flooring system.

Slabs are structural members forming floors and roofs in buildings. The dimensions of each bay are 5 6x5 4m. The floor system is the major part of a building structure. They may be solid of uniform thickness or ribbed with ribs running in one direction or two directions waffles.

Overview of the one way slab. The ribs are supported on girders that rest on columns. A reinforced concrete slab is built integrally with its supports and consists of equal span of 15 ft. Slab design is comparatively easy when compared with the design of other elements.

One way slab action is assumed in a ribbed floor slab with joist beams made of the precast double tee section in the ribbed floor with integral beams and also in hollow block or hollow cored slabs. Ribbed floors consisting of equally spaced ribs are usually supported directly by columns they are either one way spanning systems known as ribbed slab or a two way ribbed system known as a waffle slab. The selection of an appropriate system is vital in achieving an overall economic building. This form of construction is not very common because of the formwork costs and the low fire rating.
