A 2 hour fire rating is required. We have thickness of slab as 130 mm. The general arrangement of the floor plan of a building is shown below.

Ce 433, summer 2013 slab design example 5 / 5 design bar cutoffs:
This example highlights code based selection of drop panel.

The floor is to support a live load of 150 psf, along with a forklift load of 4.0 kip per wheel on a 40 wheel center (8.0 kip per axle). Bs 8110 if the following conditions applied. Design the slab following the provisions of the aci code.
The slab is build above a dry river bed that can be flooded from time to time, and therefore spans from columns to columns in a 4.85 m x 5.85 m grid.
Civil engineering design (1) analysis and design of slabs 2006/7 dr. According to the way loads are transferred to supporting beams and columns, slabs are classified into two. The slab is 300 mm thick and columns are 400 mm square. Suspended slabs are made of concrete and steel mesh, the same as a ground slab.
Slabs are usually used in floor and roof construction.
Introduction concrete slabs on grade are a very common type of concrete construction. Plate concrete floor system design” example. Columns are 30cm x 30cm, equivalent partitions load=250 kg/m2, live load = 400kg/m2, = 280 kg/cm 2 = 4200 kg/cm 2, slab thickness = 16cm The requirements of as 3660.14 are also covered.

A reinforced concrete slab is built integrally with its supports and consists of equal span of 15 ft. Determination of moments of slabs (laterally. Suspended slabs are typically buildup in two ways: Under this type of slab mainly flat slabs, conventional slabs, hollow core ribbed slabs, waffle slabs, solid slab raft and composite slabs are considered as examples in building design.

Under the suspended slab under convention type the two types of slabs are used in the building designs they are mainly depends upon the. The construction and design of concrete slabs on grade d. 3 8.6 200 x 200 hole figure 3.18 part p plan of flat slab 3.4.1 actions kn/m2. As an example, we’ll analyse hereafter the design of a free suspended elevated slab, used as main ground slab (350m² area) of a social chalet within a school.
Design of typical floor slab:
The reinforcement is placed in reusable and adjustable molds, and the concrete is poured, vibrated. Matthew stuart, p.e., s.e., f.asce, secb course content slab on grades construction: 13.6.1 direct design method (ddm) for slab systems with or without beams loaded only by gravity loads and having a fairly regular layout meeting the following conditions: At sng engineers we have several years of experience in designing and detailing several different types of concrete frame system.
Design and detail the panel 1 of the building using the following data;
The efm solution is also used for a detailed comparison with the analysis and design results of the engineering software program spslab. View slab design example.pdf from csc 123a at african institute of mathematical sciences. Considering m20 grade of concrete and fe 500 steel of diameter of 10 mm effective depth: One way slab design example:
Thickness of floor slab = 150 mm concrete cover = 25 mm characteristic variable load = 1.5 kn/m 2 f ck = 25 n/mm 2 f yk = 460 n/mm 2
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. The floor slabs are at 4.50 m vertical centres.
