THE OLDEST UNDERGROUND RAILWAYS IN THE WORLD AND THEIR ANNIVERSARIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The five oldest underground railways started to be operational in the 19th century. These were the metros in London, Athens, Istanbul, Budapest and Glasgow. Undoubtedly, world primacy of status in terms of age belongs to ...
LOCALIZATION ANALYSIS OF DAMAGE FOR ONE-DIMENSIONAL PERIDYNAMIC MODEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Peridynamics is a recently developed extension of continuum mechanics, which replaces the traditional concept of stress by force interactions between material points at a finite distance. The peridynamic continuum is thus ...
MECHANICAL AND CHEMICAL ACTIVATION OF BLAST FURNACE SLAG AND ITS INFLUENCE ON THE MECHANICAL PROPERTIES OF THE RESULTING CEMENT PASTE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The usage of waste materials is a very important global topic. The large amount of waste everywhere in the world needs to be processed or disposed. Landfilling is not an option anymore, because of European legislation and ...
EVALUATION OF IMPACT OF ELEVATED TEMPERATURES ON YOUNG’S MODULUS OF GLT BEAMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The influence of elevated temperatures on mechanical behavior of glued laminated timber beams is examined on the basis of tensile tests. Dog bone samples prepared from beams exposed to fire of variable duration were ...
MODELING TIME-DEPENDENT DEFORMATIONS OF CONCRETE MEMBERS SUBJECTED TO SYMMETRIC AND ASYMMETRIC DRYING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The time-dependent behavior of concrete members with uniform cross-section subjected to symmetric drying can be predicted with one of many models anchored in the design codes. Since these models use the cross-sectional ...
COMPARING THE HOEK-BROWN AND MOHR-COULOMB FAILURE CRITERIA IN FEM ANALYSIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This paper revisits the issue of a potential substitutions of the Hoek-Brown failure model by the standard Mohr-Coulomb model in the stability analysis of rock masses. The derivation of equivalent shear strength parameters ...
SIMULATION OF T-JOINTS BETWEEN RHS STEEL MEMBERS WITH OFFSET IN ABAQUS CAE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The current paper focuses on numerical simulation peculiarities of offset welded rectangular hollow section joints. Understanding the modelling techniques can result in easier and faster and above all correct outcomes from ...
FRACTURE ENERGY OF ILLITIC RAMMED EARTH WITH HIGH WATER-CLAY RATIO
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The article is focused on design of mixture of rammed earth, producing, testing and determination of fracture energy of unfired rammed earth and its stress-strain curve in tensile bending test. Three different mixtures of ...
INFLUENCE OF EARTH COMPOSITION ON ADSORPTION CAPACITY OF METHYLENE BLUE DYE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
Final properties of unfired earth are influenced by composition of earth mixtures. Methylene blue test could be useful method for analysis of earth composition. This would facilitate of designing unfired earth building ...
NUMERICAL SIMULATION OF SLUMP FLOW TEST OF CEMENT PASTE COMPOSITES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This study presents a numerical simulation of the mini-slump flow test performed on the Haegerman table, according to EN 1015-3. The two-dimensional axisymmetrical Volume of fluid (VOF) model is used for the calculation. ...
