  The scope of work will be as below. Analysis and design of flat slabs is to be carried out for staggered columns using Equivalent Frame Method with IS , ACI , BS & EC2.   Flat Slab Floor System. A flat slab is a one-way or two-way system with thickenings in the slab at the columns and load bearing walls called ‘drop panels’ Figure 9. Drop panels act as T-beams over the supports. They increase the shear capacity and the stiffness of the floor system under vertical loads, thus increasing the economical span range.

In the Eurocodes, the analysis of flat slab is the same as that recommended in BS According to clause of BS , the simplified method can be used for flat slabs that the lateral stability is not dependent on the slab and columns provided that the following conditions are met;. Document Type: Book: All Authors / Contributors: Concrete Society. ISBN: OCLC Number: Notes: Cover title. "This handbook amplifies Concrete Society technical report no. 17, Flat slabs in post-tensioned concrete with particular regard to the use of unbonded tendons.". As forming costs increased, most flat slab design eliminated either the drop panels or the capitals and brackets. 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 Author: Edward S. Hoffman, David P. Gustafson, Albert J. Gouwens.

The design of the post-tension flat slab can be done by using load balancing and equivalent frame method. Among of both the equivalent frame method is widely used.

What is a flat slab? - Flat Slab resting directly on columns - Flat Slab with drop panels - Fla.   Method 1: As Suro mentioned, this method involves specifying design parameters such as Steel and concrete strength (FYMAIN, FC), Clear cover for the bars, etc. and the "DESIGN ELEMENT" command from the Design page of the STAAD Modeling mode. Those instructions, called parameters and design commands, will then get embedded into the STAAD input. modeling, analysis and construction of flat slab structures. Park et al.

Direct Design method: The following limitations apply to the slab system. * There must be at least 3 continuous spans in each direction viz (column strip, middle strip, column strip) * The panels should be rectangular and the ratio of longer. Flat Slab Analysis and Design designs beamless concrete slab floors (flat slab or waffle slab) in accordance with ACI The analysis and design follow the equivalent frame analysis method of the ACI code, which considers a one-bay wide strip of the floor system as a continuous frame.3/5(4).

LITTLE CONFUSION REGARDING FLAT PLATE & FLAT SLAB!!!!. The flat plat is a slab of uniform thickness while in flat slab there is thickened slab region in the vicinity of the column that includes either drop panel or column capitals.

Figure: Drop Panel & Column Head 5. Excel Sheet to Design Flat Slab According to Eurocode. Excel Sheet to Design Flat Slab Common practice of design and construction is to support the slabs by beams and support the beams by columns. This may be called as beam-slab construction. The beams reduce the available net clear ceiling height.

Basics of Reinforced Concrete Slab Design Slabs are generally designed on the assumption that they consists of a number of beams of breadth ‘one meter’. Contents:1 Basics of Reinforced Concrete Slab Design2 1.

Effective Span of Slab3 2. Thickness of Slab4. Flat slab can be described as one sided or two-sided support system where sheer load of the slab is accumulated on the supporting columns and a square slab known as ‘drop panels’. Flat Slabs are specifically created for most of the construction and for asymmetrical column layouts like floors containing curved shapes and ramps etc.

FOREWORD The Reinforced Concrete Design Manual [SP(11)] is intended to provide guidance and assistance to professionals engaged in the design of cast-in-place reinforced concrete structures. The first Reinforced Concrete Design Manual (formerly titled ACI Design Handbook) was developed in accordance with the design provisions of ACI Building Code by ACI CommitteeDesign.This design, with contractor collaboration, has set a new standard in office buildings and created a new efficient architecture which gives further enhancement to core-only tall buildings.

An important feature of the concrete framing design is a dramatic foot corner cantilever achieved with a inch deep post-tensioned upturned beam.Design of Slab (Examples and Tutorials) by Sharifah Maszura Syed Mohsin Example 1: Simply supported One way slab A rectangular reinforced concrete slab is simply-supported on two masonry walls mm thick and m apart.

The slab has to carry a distributed permanent action of kN/m2 (excluding slab self-weight) and a variable action of 3.
