Type of slab: One-way solid slab: Slabs of uniform thickness bending and reinforced in one direction. Suitable only for relatively short spans. Two-way solid slab: Slabs of uniform thickness bending and reinforced in two directions. Economical for medium spans with intermediate to heavy loads. With Wisdom We Explore Introduction www.uthm.edu.m 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 Example of Design. The slab is the horizontal structural component that provides a flat and purposive surface. Such a surface may be floor, roof or ceiling. One way slab & Two-way slab are the types of the slab. Slab carries the loads imposed on it and duly transfers the forces either in a one way or in a two-way mechanism Design a R.C Slab for a room measuring 6.5mX5m. The slab is cast monolithically over the beams with corners held down. The width of the supporting beam is 230 mm.The slab carries superimposed load of 4.5kN/m 2 Slab design is comparatively easy when compared with the design of other elements. The first stage of the design is finding the bending moment of the slab panels. 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. One way spanning slabs

Design Of Reinforced Concrete Structures ii Two-Way Slabs 8 C: Cross sectional constant defines torsional properties C = X: smallest dimension in the section of edge beam. Y: Largest dimension in the section of edge beam. Note: the C relation is applicable directly for rectangular section only, but when used for L-Shape beams, we should divide it to two rectangular sections and find C Determine slab type and layout. Choose slab thickness that should be adequate for avoiding excessive deflections and satisfy shear at the interior and exterior columns.

Distribute moments across slab width Consider a solid slab of area A located between two large parallel plates that are a distance H apart, as shown in Fig. 2.3(b).Initially, the solid material is at a temperature T o.At time t = 0, the lower plate is brought to a higher temperature T 1, and maintained at this temperature.A linear steady-state temperature distribution is developed based on a constant rate of heat flux q (J/(m 2 s. The thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure. The minimum thickness can be determined by many factors: • Shear strength of beamless slabs (usually a controlling factor); slab must be thick enough to provide adequate shear strengt

Soil compressibility and bearing capacity values are normally used to predict and limit differential settlements between differen The coefficient method may be the simplest, easiest and the quickest approach for the design of two-way slab supported by edge beam on all slab sides. This method was provided in the American Concrete Institute (ACI) in 1963 to design two-way slabs carried by steel beams, deep beam, or walls Waffle slabs are reinforced concrete slabs that are normally employed for large-span construction. They can be described as the equivalent of 2-way spanning solid slabs but with ribbed slab system spanning in both directions. The design concept of waffle slabs is similar to that of ribbed slabs, with the difference being that waffle slabs have ribs spanning in both directions, and the.

Structural Design of Ribbed Slabs. Ribbed slab is a type of reinforced concrete slabs in which some of the volume of concrete in the tension zone is removed and replaced with hollow blocks or left as voids. This reduction in the volume of concrete in the tension zone (below the neutral axis) is based on the assumption that the tensile strength. Design of Two-way Slabs Example 1.2 Use (i) WSD, (ii) USD to design the two-way slab shown below, carrying floor finish = 30 psf, random wall = 50 psf and live load = 60 psf [Given: f c = 3 ksi, f 5. BASIC STEPS OF TWO WAY SLAB DESIGN : 1. Choose layout and type of slab. Type of slab is strongly affected by architectural and construction considerations. 2. Choose slab thickness to control deflection. Also, check if thickness is adequate for shear. 3. Choose design method Design steps: Step 1: Preliminary Design: Find depth of slab using deflection control criteria. Take Span/d = 25 for simply supported slab. = 30 for continuous slab. D ≥ D min = 100mm for normal design. = 125mm for earthquake resistant design. Step 2: Analysis of slab: Analyze the slab considering the slab as beam of 1m width and find. The two way and one way slab design are mainly focused. The thickness of steel reinforced slab typically between 100 and 500 mm thick. In building, the slab thickness is normally between 100 to 200 mm. It is advisable not to use slab of thickness greater than 150 mm in building because it increases the self-weight which causes severity in.

Solid Slab Bridges: Advantages, Disadvantages and Principle

Slab-on-grade foundation. Slab-on-grade or floating slab foundations are a structural engineering practice whereby the concrete slab that is to serve as the foundation for the structure is formed from a mold set into the ground. The concrete is then placed into the mold, leaving no space between the ground and the structure. This type of construction is most often seen in warmer climates. The solid flat slab design process follows the provisions made in the ACI 318-11 and the plastic voided slab design process is modified from the Bubble Deck Design Guide for compliance with BCA using AS3600 and Euro code 2. The various parameters like total bay weight, flexural reinforcement, solid perimeter, moment capacity of the voided.

Meter Feet Width: Length: Slab Support Condition Solid Slabs Continuous at one End Solid Slabs Continuous at both Ends Simple span solid slabs Cantileve Design Considerations in Slab: Locate position of wall to maximize the structural stiffness for lateral loads. Facilitates the rigidity to be located to the center of building. Its necessary to check the slab deflection for all load cases both for short and long term basis. In general, under full service load, Deflection (d) < L/250 or 40 mm. BASIS OF FLOOR SLAB ON GRADE DESIGN 2-1.

Stresses in floor slabs on grade resulting from vehicular loads are a function of. reinforced concrete slabs and plastic voided slabs with the same design constraints is discussed. Plastic voided slabs remove concrete from non-critical areas and replace the removed concrete with hollow plastic void formers while achieving similar load capacity as solid slabs. Voided slab

Structural Design of Flat Slabs to Eurocode 2. Flat slabs can offer economical solutions to wider floor spans in a reinforced concrete building. Flat slabs are slabs that are supported directly by columns without floor beams. The columns may or may not have drops. There are many advantages of flat slab such as increased head room, easier flow. UNIT NO 3: DESIGN OF REINFORCED CONCRETE SLAB 3.1 INTRODUCTION Reinforced concrete slabs are used in floors, roofs and walls of buildings and as the decks of bridges. The floor system of a structure can take many forms such as in situ solid slab, ribbed slab or pre-cast units. Slabs may span in one direction or in two directions and they may be. One-way Slabs • Normally design as a beam with cables running in the direction of the span at uniform centres. • A slab strip of unit width is analysed using simple beam theory. • In any span, the max cable sag, zd depends on the concrete cover requirements and the tendon dimensions. • When zd is determined, the prestressing force required to balance a Types of Design For Two Way Slabs 1-Two Way Solid Slab With Beams.
