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. Short-Term
