This paper reports on the application of a simulated annealing algorithm to the minimum cost design of reinforced concrete retaining structures. Cantilever retaining walls are investigated, being representative of reinforced concrete retaining structures that are required to resist a combination of earth and hydrostatic loading. To solve such a constrained optimisation problem, a modified simul...

The effective analysis of the nonlinear behavior of cement-based engineering structures not only demands physically-reliable models, but also computationally-efficient algorithms. Based on a continuum interface element formulation that is suitable to capture complex cracking phenomena in concrete materials and structures, an adaptive mesh processing technique is proposed for computational simul...

Reinforced concrete (RC) Structures constructed over six decades ago are now approaching the end of their service life and showing serious level of deterioration and therefore, prediction of service life of structural materials and components has gained significance. With the increased efforts of researchers, development in computer knowledge and advancement in building materials science, it is...

Aging of concrete structures occurs with the passage of time and has the potential, if its effects are not controlled, to increase the risk to public health and safety. Activities have been conducted to address factors related to quantifying the effects of age-related degradation on nuclear power plant concrete structures and components. Environmental effects that can lead to age-related degrad...

The existing stochastic models for deterioration of reinforced concrete structures is extended by adding modelling of “loss of bond” due to corrosion between the reinforcement bars and the surrounding concrete.

The problems of degradation concrete and reinforced constructions buildings long operation are formulated on the basis performed field researches its urgency is noted in work. authors analyzed a number works this problem. In particular, results technical diagnostics many structures, both newly built long-term operation, described. necessity periodic noted. Based these studies, main factors that...
