Offering an essential background for a thorough understanding of building code requirements and design procedures for slabs, Reinforced Concrete Slabs, Second Edition provides a full treatment of today's approaches Cited by: This book provides an up-to-date description of the latest procedures for analysis and design of reinforced concrete slabs.
It explains the yield line method of analysis and Hillerborg's strip method of design, and discusses the basic North American and British practices. The yield-line method of analysis provides a powerful means of identifying the ultimate load carrying capacity of reinforced concrete slabs.
Benefits of the yield-line method are that it will often identify additional reserves of strength when applied to the analysis of existing slabs, and to highly economic slabs when used in by: 1. The yield-line method of analysis is a long established and extremely effective means of estimating the maximum load sustainable by a slab or plate.

The book has been written with an engineering approach in mind: We will start by identifying the problems to be solved and then develop a method to solve these. This book discusses the influence of steel fiber-reinforcement on the shear strength of slab-column connections; sulfur-treated concrete slabs; yield line analysis of orthotropicaly reinforced exterior panels of flat slab floors; and behavior of flat slab/edge column joints.

and a numerical example of the numerical yield line analysis of a reinforced concrete slab is given. INTRODUCTION The yield line method is a simple and efficient method to calculate the plastic collapse load of flat, relatively thin, plates of rigid-perfectly plastic material when transversely loaded in bending.
The yield line method is a method for the design or assessment of concrete slabs. It's value is that it accounts for redistribution of forces that take place after the slab's reinforcement yields. This is different from more widely used elastic methods, which do not allow for steel yielding.
Yield line theory, on the other hand, is an efficient way of determining the collapse load of reinforced concrete slabs, and it pre-dates limit analysis. The term ‘yield line’ (in Danish: ‘brudlinie’, literally meaning ‘line of rupture’) was coined in by Ingerslev  to describe lines in the slab.
Besides dealing with yield line analysis for slabs, the book explains the working stress method and its use for designing reinforced concrete tension members, theory of redistribution of moments, and earthquake resistant design of structures.

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 strengthFile Size: KB. Yield Line Analysis: Yield line theory permits prediction of the ultimate load of a slab system by postulating a collapse mechanism which is compatible with the boundary conditions.
Slab sections are assumed to be ductile enough to allow plastic rotation to occur at critical section along yield Size: KB. OVERVIEW The theory presented in this chapter extends the ultimate load analysis of structures, begun in Chapter 18 for beams and frames, to reinforced concrete slabs.

Yield line analysis is a useful method for design of reinforced concrete slabs, but has been limited to slabs of simple geometry, because up to now there has been no generally applicable and fully automatic computational procedure for complex-shaped slabs.
Herein, a new yield line method that can be applied to any convex polygonal-shaped slab. Slab: 89, lbs. for the slab. Calculating the subtotal for the floor, ceiling, walls, footing, and slab: Solution for #5: The total dead load of the structure can be found by adding the two above subtotals:lbs Solution for #6: To determine if the dead load (structure weight) from the house is sufficient to.
Analysis of forming –Slipline Field Method Methodology of slipline field analysis: Slab analysis of the forming process is considered approximate due to the assumption of homogeneous deformation of material.
Slipline field analysis is more accurate as it considers the non-homogeneous deformation also. Chapter 23 Yield Line Analysis for Slabs - Online Chapter; (source: Nielsen Book Data) Summary The fifteenth edition of the classic text, Design of Concrete Structures, is completely revised using the newly released American Concrete Institute (ACI) Building Code.

Flat slabs may have drop panels at columns and columns may have capitals. Analyses are for a one-bay-wide strip using the equivalent frame analysis method of the ACI code. The strip may have up to 20 spans and may have cantilevers at the ends.The "Slab on Grade" worksheet assumes a structurally unreinforced slab, ACI"Type B", reinforced only for shrinkage and interior load condition is assumed for flexural is, the concentrated post or wheel load is assumed to be well away from a "free" slab edge or original theory and equations by H.M /5(1).Comparison of Field and Laboratory Strengths of Concrete Slabs Manuel CELAYA1, slabs are closely related with a high level of confidence.
Differences between these moduli can be attributed to experimental errors, conservatism built in the PSPA analysis, and the damage to the cores and beams during drilling and saw cutting .
