The result will be a high quality reinforced concrete slab flooring. Let’s discussed the design code requirement specified for slab reinforcement details. See more ideas about concrete design, reinforced concrete, reinforcement. Its composition consists of sand, cement, water and gravel (sometimes also crushed or ground stone), and sometimes some additional element is added to add some extra feature. The two way and one way slab design are mainly focused. You can find out more about which cookies we are using or switch them off in settings. In a typical reinforced concrete building, reinforcement bars arranged as mats are incorporated into a concrete plate of minimum thickness 125 mm to … 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. If you disable this cookie, we will not be able to save your preferences. After the ground is adequately prepared, the wooden mould must be made. Slabs are generally designed on the assumption that they consists of a number of beams of breadth ‘one meter’. You can unsubscribe at any time. The moulds are used for the construction of a floor and pillars. For positive and negative moments in both the middle and column strips, the maximum spacing of reinforcement at critical design sections shall not exceed two times the slab thickness. Slabs Reinforced concrete slabs, at least those designed to span in one direction, are no different conceptually from any other beams, with the following three caveats. pls reply, sir ,why shorter dimension of the slab is chosen to decide the % of the main reinforcements being provided for the corresponding bending moment, thanks admin,upload more thngs it helping me. We will inform you about latest news and projects in the industry. Reinforcement in the upper half of the concrete slab will act as a restraint to concrete shrinkage. The stab has an overall thickness of 200 mm and an average effective depth of 170 mm. High resistance, suitable for heavy machinery: 16 or more cm. Kindly assist on how to go about it. The maximum bending moment per meter width of slab. 2- Slab Reinforcement Details. Therefore, at BECOSAN®, we, BECOSAN® is an eco-friendly floor, specialising in the treatment of cured concrete floors making them smoother, abrasion resistant, cleaner and more beautiful, This century has seen a dramatic improvement in the capabilities of 3D printing. It is preferable to do this work with fresh concrete, without drying, because afterwards it will be challenging. Before even starting to make the concrete mix, the ground where the slab is to be placed must be prepared. Find the dead load and the live load per square meter of the slab. Determine moments at critical sections in each direction, normally the negative moments at supports and … Suppose a slab is supported at the ends and also at intermediate points on beams, the maximum sagging and hogging moments to which the slab is subjected to due to uniformly distributed load, can be computed as follows: Let = intensity of dead load per square metre. Design the slab as one way simply supported slab. Please enter your email address. in ratios of span to thickness, is the loading=dead load only? CE429: REINFORCED CONCRETE DESIGN Practice Problem The structural floor plan of an office building is shown below. The recommended thickness for each reinforcement concrete slab will vary depending on the desired resistance: After finishing the pouring of the mixture, you can create rough finishes or create the reinforced concrete slab expansion joint, which is a process recommended for floors that are going to be subjected to a lot of weight. Two Way Slab Design Spreadsheet > Reinforced Concrete Design > CivilWeb Spreadsheets. This method is obsolete. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings. In most cases, the slab thickness is designed as an unreinforced concrete section. © 2009-2020 The Constructor. MasterKey: Concrete Slab Design is an add-on to MasterFrame and MasterFrame: Finite Element Analysis for the FEM based design of concrete slabs.. With the new MasterKey: Concrete Slab Design module, the specification and design of the longitudinal and shear reinforcement in slabs is now an easy process, allowing you to interactively identify and resolve any slab failure areas. The details of slab reinforcement are given below. The following slab reinforcement arrangements are specified in the BS 8110 Part 01. Sign Up to The Constructor to ask questions, answer questions, write articles, and connect with other people. (2) The first perimeter of shear reinforcement should be placed at d/2 from the face of the loaded area. The choice will depend on the objective being pursued. One aspect to highlight is that if steel bars are incorporated into the concrete, what is known as reinforced concrete is formed. am a civil eng. The size of grains used will depend on the what you are looking for. The frequent use of slab is found as floor and roof in building, decks in bridges, top and bottom of tanks, road pavement and so on.

A reinforced concrete floor is one that is made from a slab, which is a flat plate made of concrete, that has both surfaces parallel to each other and inside has steel beams that support the structure. There are several types of treatments for concrete floors that can be done after using concrete. The mixture can be made by hand or in a machine – a concrete mixer. Main reinforcement which is based on the maximum bending moment shall not be less than 0.15 per cent of the gross sectional area. Between the beams there can be 15 x 15 cm or 15 x 25 cm separation. give me a suggetion to provide a slab for a room of 40' x 15' without beams. The floor slab design procedure presented The maximum allowable stationary live load is lim- herein is based on limiting the critical tensile stresses ited by both the positive bending moment stress produced within the slab by the vehicle loading, as under the load and the negative bending moment Floor Slab Design Floors are designed as slabs on grade. Country slabs are plate elements used to form the floors of buildings. Student. Design Example of a two-way slab Reinforced concrete (R.C.) Lecture series on Design of Reinforced Concrete Structures by Prof. N.Dhang, Department of Civil Engineering, IIT Kharagpur. The materials to be … Tunnel Alignment: What is its Importance in Tunnel Construction? The slab has to carry a distributed permanent action of 1.0 kN/m2(excluding slab self- weight) and a variable action of 3.0 kN/m2. Lost your password? Depending upon the requirement and the design of the structure, different types of slab such as concrete slab, flat slab, waffle slab etc can be used. this drawing is drafted in AutoCAD format with dimension detail. This website uses Google Analytics to collect anonymous information such as the number of visitors to the site, and the most popular pages. Loading docks are a part of intralogistics that help move products, Logistics is increasingly acquiring greater importance in the strategic planning of businesses. Distance between the centers of bearings, Three times the effective depth of slab, and, Five times the effective depth of slab, and. Keep up to date on the latest industry news, projects and developments. Medium resistance, suitable for light vehicles: 13-15 cm. Find the effective depth ‘d’ from the above equation. The basic design procedure of a two-way slab system has five steps. Design the slab following the provisions of … A mix that has more water will be easier to handle, while a higher proportion of cement generates more durability. Design of Reinforced Concrete Slabs 115 (1) The first failure zone is from the face of the loaded area to the perimeter 1.5d away. This type of concrete is ideal for use in constructions that require high durability. Minimum reinforcement in either direction shall be 0.15 percent of total cross-sectional area. 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. Each reinforcement concrete slab must go through a build process that is not complex, but must be strictly followed. The diameter of main bars may be from 8 mm to 14 mm. One Way Slab Design Example: A reinforced concrete slab is built integrally with its supports and consists of equal span of 15 ft.
