Influence of multiple cyclic loading on the selected parameters of lightweight concrete
Alexa, Martin ; Misák, Petr (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with the observation of the values of selected parameters (especially the static modulus of elasticity) of light-weight concrete in compression before and after multiple cyclic loading. The deformation of test specimens during multiple cyclic loading were measured with resistive strain gauges. Test specimens (cylinders with a diameter of 150 mm and height of a 300 mm) were cyclically loaded and up to 4 500 loading cycles were performed. The aim of this thesis is assessment changes in the values of static modulus of elasticity depending on the number of loading cycles.

The influence of multiple cyclic loading on the properties of ordinary concrete
Pešek, Lukáš ; Topolář, Libor (referee) ; Kocáb, Dalibor (advisor)
The diploma thesis deals with the observation of elastic and strength properties (primary moduli of elasticity and Poisson's ratio) of ordinary concrete before and after multiple cyclic loading. Test specimens with cylinder shape and diameter of 150 mm and height of a 300 mm were cyclically loaded up to 5000 loading cycles with resistive strain gauges to measure deformations so static modulus of elasticity could be determined. Further on the test specimens were performed tests to determine the dynamic modulus of elasticity and whole testing was finished with compressive strength test. The results were processed and selected properties evaluated in tabular and graphical form to determine statistical data and formulate a conclusion.
