The two-way slab is designed for both the directions as it bends in both directions. 3 Prestressed Flat Slabs and Plates Prestressed flat slabs and plates have been developed mainly in Australia and the USA over the last 30 years. Features of the design. Today, the flat plate form is preferred for light loads and short spans; the flat slab with capitals and brackets only, in heavy duty designs where few partitions are used; and the flat slab with drop panels only, for heavy duty design with or without partitions. Yasser El Leathy and other professors. Different techniques have been developed for strengthening R/C slabs against punching: enlargement of the support, gluing external fibre reinforced polymers or casting a bonded concrete overlay (BCO) on the slab's top surface, insertion of post-installed steel bolts, application of fibre reinforced polymers cords as shear reinforcement. Complete Screen Number 1 with information about the bridge and the analysis type: for this example, Slab Bridge Designer 2. IS 456: 2000 PAGB 30. The spacing between the perimeter columns and the core varies between 7 and 9 meters, so we are also contemplating the option of having a post-tensioned system, but this is perhaps irrelvant for. For example, many walls are “load bearing,” and without a foundation of some sort to rest upon, would not only sink into the soil to some extent, but would also respond to the soil's every movement. 2 Procedure for Obtaining HAZUS-compatible Fragility Curves 125 5. 3380 Trickum Rd Bldg 500, Suite 100 Woodstock, GA 30188 www. 2] gives the following guidelines for proportioning. This Technical Note reviews the levels of acceptable deflections and the currently available methods for their estimate. So, I found a way to speed things up a bit, and protect the slab edges. In the case of existing structures the method of approach changes. Tests performed in Denmark, Germany, and Holland revealed the bubble-voided flat slabs had a flexural stiffness about 90% that of a solid slab with. Voided biaxial slabs are reinforced concrete slabs bubblfdeck which voids reduce the amount of concrete. Hence in warehouses, offices and public halls some times beams are avoided and slabs are.

Virus-free and 100% clean download. This effect should be taken into account to. 3 of ACI 318-08 allows the use of shear reinforcement for slabs. Accessibility Help. In flat-plate floors, slab-column connections are subjected to high shear stresses produced by the transfer of axial loads and bending moments between slab and columns. Flat slabs offer flexibility to structural designers in terms of distribution of superimposed dead loads, without the constraints associated with beam locations in slab-beam systems. This design is a complete flat plate slab design, from shear to bending along with design of columns and shear head reinforcement. 0 kN/m2 Water proofing : 2. 0 kN/m2 Terrace finish : 1. Flat slab is defined as one sided or two-sided support system with sheer load of the slab being concentrated on the supporting columns and a square slab called 'drop panels'. Flat slab system is very simple to construct and is efficient in that it requires the minimum building height for a given number of stories. of Architectural Engineering, Hanyang University. In this course, we will only be studying flat plate slabs (slabs without drop panels) without shear reinforcement. economical thickness of flat slab with drop and without drop are selected and cost comparison is done by using S.

The self-weight of the completed concrete slabs is generally assumed in backpropping calculations to be based on a density of 24 kN/m³ for building multi-storey flat slab structures. of Measured Moments with Moments Computed for Center Panel of 25-Panel Plexiglass Flat Slab Model. In order to prevent the column from puncturing the slab, appropriate shear reinforcement, slab thicknesses, and column geometries are required. This thesis is concluded to that hollow block slab is suitable system because the lowest cost and other features make it suitable structural system for hot places like Sudan. Even though several analytical methods, including finite element and equivalent frame approaches, have been used for flat plate systems subjected to static gravity. The two-way slab will deflect in a dish or saucer-like form under the action of loads. 1) In lieu of detailed calculation for deflections, ACI 318 minimum slab thickness for two-way construction without interior beams is given in Table 8. 1-3 for further clarification of other terms.

Uses Of Flat Slab: 1. 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:. Effective roof insulation has three or four insulation layers. Slab without drop and column. The default Layer’s list of SCADA includes the layers related to the flat slabs. Slab Reinforcement. The 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. Occurring soon after the torsional release these flexural cracks developed on the undersurface of the slab at midspan between the columns and at the face of the two lines of tee pieces. A numerical investigation was conducted using the finite element. For commercial buildings flat slab rising up to 10 to 20 stories is quite popular. Concrete is good in taking compression and steel is good in tension. Flat slabs with drop panel: Flat slab thickness at its column.

Typically, a flat slab is made with reinforced concrete, in which rebar is criss-crossed in the forms to provide support and reinforcement once the concrete is poured and hardened. In Figure 2, we show the converted phases associated with the Moho, slab, and the midcrustal structures. Flat slabs can offer economical solutions to wider floor spans in a reinforced concrete building. Two-way slab action is assumed in a ribbed floor made of the double-tee section (precast), in the ribbed floor with integral beams, and also in hollow-block or hollow-cored slabs. The first step in placing large concrete slabs, patios, driveways, etc. Ribbed slabs (One-way joists) Introducing voids to the soffit of a slab reduces dead weight and increases the efficiency of the concrete section. 5 Panels, column strips and middle strips is y-direction 1. Because of the brittle nature of shear failures, conservative design is necessary. Drop panels act as T-beams over the supports. The slab is part of a larger floor plate and is taken from Guide to the design and construction of reinforced concrete flat slabs[29\ where finite element analysis and design to Eurocode 2 is illustrated. Paul - Doctoral Thesis / Dissertation - Engineering - Civil Engineering - Publish your bachelor's or master's thesis, dissertation, term paper or essay. In addition to this, the shear capacity can also be reduced in particular around the column head where large shear forces can develop. 3) For flat slab structures subjected to lateral (horizontal) loads, the stiffness of the horizontal (floor) members should be based on 40% of the full width of the panels. Warehouse or industrial floors usu-ally have greater durability requirements and need to be flat and level, while other interior floors that are covered with floor coverings do not have to be as smooth and durable. The benefits of using in-situ concrete flat slab construction should be investigated at the conceptual design stage. It is having a basic information about flat slab. normal weight concrete f'c of slab = 5 ksi f'c of columns = 6 ksi partitions (SDL) = 15 psf live load = 60 psf ignore live load reduction. The column tends to punch through the slab in Flat Slabs, which can be treated by three methods: Using a drop panel and a column capital in flat slab. 3 Loads Self-weight of concrete slab: 6. Drop panels act as T-beams over the supports. 2 VERSION 6. For lower loads they can have constant thickness and are called flat slabs or flat plates, see Figure 1.

Contraction, construction, and expansion joints. A slightly deeper section is required but these stiffer floors facilitate longer spans and provision of holes. download 1 file. Panel may be divided into column strip and middle strip. However, the span influencing their design is the longest and they require more steel compared to two-way slabs. The saving of materials tends to be offset by some. These include sufficient flat plate thickness, drop panels, column capitols, reinforcing bars, shearhead reinforcement, and headed stud shear reinforcement. Tests of flat plate structures indicate that, in most practical cases, the capacity is governed by shear.
