Course specification
Course is active from 01.10.2007.. Precondition courses
Enabling students to select adequate rheological models to analyse concrete and both concrete prestressed and poststressed structures with inclusions (concrete shrinking and leaking, and prestressed steel relaxation). Enabling them for experimental researches of long-lasting processes in concrete and prestressed structures. Based on theoretical ideal models, enabling students to select adequate models for predicting the behaviour of monolith concrete, prefabricated – monolith, and prestressed (full and partial) structures. Possibility to analyse gradual building in monolith and precast concrete and prestressed structures. Rheology of the fresh concrete mass and the influence of individual components on concrete shrinkage and leaking. Concrete shrinkage and its inclusion into complex structure analyses. Laws on idealised body deformations (Hooke`s, Newtonian fluid, Sent-Benan`s, Maxwell`s, Kelvin`s, Bingham`s). Body and combinations in selecting rheological models. Fundamentals in viscoelasticity and its adaptation to reinforced and prestressed elements and structures. Aging theory. Inherited aging theory. Integral and algebra connections between stress and strain and the application of step-by-step method for long-term process analysis in concrete structures. Analogy of dynamic and rheological models. Numeric and experimental analysis on concrete leaking and prestressed steel relaxation in partially and fully prestressed structures. Partially auditorial through lectures and tutorials, and partially in seminar papers that are publicly presented and defended and have a share in the candidate`s grade.
