The method presented here, yield line theory, was developed in the early s by the Danish engineer, K.W. Johansen. YIELD LINE THEORY There are two approaches to the calculation of the ultimate load-carrying capacity of a reinforced concrete slab.

RE: Yiel line theory for point loads BAretired (Structural) 6 Nov 16 There should be two negative yield lines, one at each of the fixed edges and one positive yield line extending from the corner where the two fixed edges meet to the long free edge. In this project, different types of reinforced concrete slabs system of different support conditions have been analyzed using yield line theory to determine the maximum resisting moment, and.

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 [7] to describe lines in. The yield-line method of analysis (Johansen ) is a long- established and extremely powerful tool for estimating the maxi- mum load sustainable by a reinforced concrete Size: 2MB.

Summary. Conventional yield-line theory for reinforced concrete slabs is extended to allow for membrane effects and moderately large dejfexions, by isolating those membrane displacement rates 0/ the rigid slab portions which do not affect yield-line positions, and developing a method of choosing these rates so that the load estimate from the work-rate Cited by: Synopsis.

The usual geometrical, statical and physical conditions for the anisotropic, perfectly plastic plate are given.

It is demonstrated that the normal moment criterion usually employed in modern yield-line theory is identical with the ‘stepped’ criterion of the classical theory, and that they both correspond to a yield surface, called the upper yield surface, which Cited by: 8.

a loaded slab) at the point of failure or the load at which an element will fail. It may be applied to many types of slab, both with and without beams.

Given a yield line with end nodes 1 and 2, bounded by planes m and n, and using the convention that plane m is on the left-hand side of the yield line for an observer standing at node 1 and looking at node 2, then a point H with coordinates [-i + (YI - y\)> y\ + (xi - Xi)} is always on the right- hand side of the yield line (see Fig.

reinforced concrete slabs. The calculation procedure is known as the yield-line theory. A yield line in a plate is similar to a plastic hinge in a frame. The Dane K.W. Johansen can be regarded as the founding father of the theory.

Yield Line Theory is one of the historic and trusted methods to predict the failure loads of slabs. Many handbooks [27,28] and researches [18,19, 23, 29] discussed this method proposing several. The yield-line method of analysis (Johansen ) is a long-established and extremely powerful tool for estimating the maximum load sustainable by a reinforced concrete apply the method successfully, traditionally users have had to know something about the rules governing the construction of viable yield-line patterns, though these rules can be memorized, and for.

Yield line theory investigates failure mechanism at the ultimate limit state. It does not deal with serviceability issues such as deflection per se. Nonetheless, deflection can be dealt with by simple formulae based on yield line moment (Kennedy and Goodchild, ). The basic assumption of the yield line theory is that a reinforced concrete.

Using virtual work and yield line theory, compute the flexural collapse load of the one-way slab in Example Assume that all straight bars are used, according to Figure b. Compare the calculated collapse load with the original factored design load, and comment on differences.

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 to reinforced concrete slab analysis and s: 2.

This book teaches a value-based approach to invest by using the Dividend-Yield Theory as a means to produce consistent returns in the stock market. Rather than focus on the nitty-gritty details of a company’s operations, Weiss places an emphasis on dividend yield patterns as a means of evaluating a stock.
