analysis and design. Once grasped, Yield Line Theory is exceedingly easy to put into practice and everyone in the procurement chain benefits. Simple design leads to simple details that are fast to detail and Yield Line Design is a well-founded method of designing reinforced concrete slabs, and similar types of elements.

Synopsis. 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

In practice, in the plastic analysis of structures, one works with either the lower bound theorem or the upper bound theorem, not both, and precautions are taken to ensure that the predicted failure load at least closely approaches the correct value. The yield line method of analysis for slabs is an upper bound method, and

What it is 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

Abstract: There is a controversy about whether the classical yield lines analysis methods are in fact different methods or simply different ways to develop basically the same method. In this paper two methods are proposed that, without invalidating previous ones, really correspond to the two different ways of performing yield

Most engineers have been taught the fundamentals of plasticity theory. They know how to perform a plastic collapse analysis of a frame, or carry out a yield line analysis of a slab. They know that these give an upper bound on the collapse load and are thus. "unsafe”. They are aware that there is also a lower bound theorem,

Introduction. The yield-line technique is the traditional method of determining the (flexural) collapse load of reinforced concrete flat slabs and steel plates. Most civil structural engineers will have encountered the technique during their undergraduate education and will be familiar with the concepts.
