EC2 Webinar - Autumn 2016 Lecture 5/2 Designing for shear in slabs • When shear reinforcement is not required -e.g. usually one and two-way spanning slabs • Punching shear -e.g. flat slabs and pad foundations. Dec 18 2020 - Reinforcement detailing of a slab is done based on its support conditions. Slab supported directly by columns are called flat slab. Two Way Solid Slab with beams This slab can be used for a wide variety of loading systems. Draw panel of slab and indicate maximum design moments shears and in- plane loads if any per unit width of slab. Even with more steel, a conventionally reinforced concrete slab is going to be more likely to crack and break than a post-tensioned slab. It's more expensive. The fact that conventional reinforcement requires more concrete and more steel means that this method is much more expensive than post-tensioning. Footing sizes are typically deeper in. Slab reinforcement is a mesh and may be formed from two sets of bars placed at right angles. The table below gives bar spacing data in the form of areas of steel per metre width for various bar diameters and spacings. Reinforcement in slabs consists of a large number bars both ways which need to be tied together to form a mat. 5. 'H' bars comply with minimum soffit slab reinforcement requirements and should not be included to calculate resistance under combined effects of DL, LL & Temperature unless an analysis is conducted that considers all those effects. 6. Girder and main reinforcement will be determined by the designer. Main reinforcement is to be shown. For one way slab, main reinforcement is computed by a formula (In limit state design) that is determined by comparing compressive force as well as tensile forces. 0.15% of Ag, for mild steel. 0.12% of Ag, for tor steel. Where Ast = Area of the steel in tension. Fu = Ultimate strength of steel. Two way Slab reinforcement details:-As per below fig, it is clear that Ly/Lx = 5/5 =1 < 2. Hence, two way slab is adopted where cranked bars (main bars) are provided on both sides of the slab. ... Ly/Lx =1 as two way slab in our theoretical studies but In site they are using oneway slab reinforcement design cause of due to economic cost wise. Bubble Deck can span far longer than a solid slab (20 to 40 times the deck thickness) in all directions, and without the need for beams! ... The grade of concrete must be above M20-M25 for Bubble Deck Slab. Reinforcement /. The reinforcement ratio is the ratio of reinforcement area to gross concrete area based on the total depth of the slab. One-way solid slabs are designed as rectangular sections subjected to shear and moment. Thus, the maximum reinforcement ratio corresponds to a net tensile strain in the reinforcement, €t of 0.004. 5. Minimum Reinforcement Ratio:. Step 3: After getting the passable results of compaction test, 75mm or 100 mm blinding concrete is arranged. Blinding concrete should be garde 20/20 SRC (Sulphate Resisting concrete). The blinding concrete facilitates to arrange a solid and flat surface for the reinforcement of raft foundation. The curing polythene sheets should be arranged. salem oregon dental implants. 2018. 9. 30. · Slab On Grade Casting Details Free Dwg Drawing; Size: 110.29 k: Type: Free Drawing Category: Structure: Software: Autocad DWG: Collection Id: 1744: Published on: Sun, 09/30/2018 - 10:21: Nikhil Chamaka Autocad dwg detail of a Slab On Grade Casting Details for a Warehouse, showing through a section.

(e) The maximum diameter of reinforcing bars (cl.26.5.2.2) The reinforcement diameter use in one-way slabs will not exceed 1/8 of the total slab depth. (f) Maximum bars distance (cl.26.3.3 of IS 456) The horizontal spacing between the parallel main steel bars is always less than three times the slab's adequate depth, or a maximum of 300 mm. Continuous oneway solid slab. This calculation is intended to show in detail the provisions of designing a slab to Eurocode 2 using essentially the same slab as used in Example 3.2. A 175 mm thick continuous slab is required to support screed, finishes, an office variable action of 2.5 kN / m2 and demountable partitions (@ 2 kN / m). Abstract and Figures. In this research, optimum design of reinforced cement concrete (RCC) ribbed slab, also known as waffle slab according to the Indian RCC code (IS 456:2000) is presented. The. The specified design strength of the concrete, is 25 MPa and the specified yield strength of the reinforcement, fy , is 400 MPa. The unit weight of reinforced concrete is assumed to be 24 kN/m3. Effective depth d= Span /((L/d)Basic x modification factor) For obtaining modification factor, the percentage of steel for slab can be assumed from 0.2 to 0.5%.. The three most common types of reinforced concrete bridge decks are : Solid slab bridge decks are most useful for small, single or multi-span bridges and are easily adaptable for high skew. Voided slab and beam and slab bridges are used for larger, single or multi-span bridges. In circular voided decks the ratio of [depth of void] / [depth of. Step 7. Determine the area and spacing of main reinforcement in both direction. The area can be calculated from given formula; Mu = 0.87 f y A s [ d - f y A s / f ck b] The spacing of main reinforcement bar should not be more than 3 times the effective depth of solid slabs or 300 mm whichever is smaller. Minimum Reinforcement Ratio According to ACI Code 7.12.2.1, for the shrinkage and temperature reinforcement, Slabs with grade 40 or 50 deformed bars = 0.0020 psi Slabs with grade 60 deformed bars = 0.0018 psi Slabs with reinforcements having yield strength greater than 60000 psi = (0.0018 x 60,000/ fy). The voids are typically placed at mid-depth of slabs in between the top and bottom reinforcement meshes . Comparing with a comparable solid slab, the reduction in the self-weight of voids slabs was in the range of 20%–30% [, , , , , , ]. This video gives visualization of the reinforcement arrangement of a one way solid slab.One way solid slab is defined as a slab that is supported by beams on. Design of the footing cantilever slab portion (per meter strip) Note that the bending moment in the slab is maximum at the face of the column (in this case at the face of the upstand beams) Width of the upstand beam = 500mm = 0 Sachpazis Date 23/04/2013 Chk'd by - Date App'd by Date RAFT FOUNDATION DESIGN (BS8110 : PART 1 : 1997) Raft and soil definition Soil definition. A flat slab is a slab (with or without drops) supported (generally without beams) by columns (with or without column heads). It is also defined as a reinforced concrete slab supported directly by concrete columns without the use of beams. Flat slabs are one of the most commonly used structural systems in residential buildings, hotels, hospitals. For one way slab, main reinforcement is computed by a formula (In limit state design) that is determined by comparing compressive force as well as tensile forces. 0.15% of Ag, for mild steel. 0.12% of Ag, for tor steel. Where Ast = Area of the steel in tension. Fu = Ultimate strength of steel.
