Finite-Element Modelling of Structural Concrete - Short-Term Static and Dynamic Loading Conditions.pdf
Structural Engineering Kotsovos The book presents a finite-element model of structural concrete under short-term Finite- loading, covering the whole range of short-term loading conditions, from static (monotonic and cyclic) to dynamic (seismic and impact) cases. Experimental data on the behaviour of concrete at both the material and structural levels reveal the Concrete Structural of Modelling Finite-Element unavoidable development of triaxial stress conditions prior to failure which dictate Element the collapse and ductility of structural concrete members. Moreover, and in contrast with generally accepted s, it can be shown that the post-peak behaviour of concrete as a material is realistically described by plete and immediate loss of Modelling load-carrying capacity. Hence rational analysis and design of ponents in accordance with the currently prevailing limit-state philosophy requires the use of triaxial material data consistent with the notion of a fully brittle material; and this approach is implemented in the book by outlining a finite-element method for the of prediction of the strength, deformation and cracking patterns of arbitrary structural concrete forms. Numerous examples are given that show both the unifying generality of this proposed Structural approach and the reliability of the ensuing numerical procedure for which the sole input is the specified uniaxial pressive strength of concrete and the yield stress of the steel. This not only offers a better understanding of the phenomenology Concrete of structural concrete behaviour but also illustrates, by means of suitable examples, the type of revision required for improving design methods in terms of both safety and economy.
