In addition, due to the change in the type of material stored in the silo, the load was increased. An analysis of all relevant impacts has begun to determine the actual stress and strain state on the structure. The construction is modeled in the Abaqus software package. Based on static influence, the necessary reinforcements are foreseen and the construction is dimensioned according to European regulations Eurocodes.

A premade squared cross-section RC column was placed inside a steel tube, and then the space between the column and the tube was filled with additional concrete. A total of fourteen stub axially compressed columns, including nine strengthened specimens and five plain reinforced concrete specimens, were experimentally tested. The main parameter that was varied in the experiment was the compressive strength of the filler concrete. Three different concrete compression strength classes were used. Test results showed that all three cross-section parts (the core column, the fill, and the steel jacket) worked together in the force-carrying process through all load levels, even if only the basic RC column was loaded. The strengthened columns exhibited pronounced ductile behavior compared to the plain R...

For building design, human activities are the most important internal sources of vibration in timber floors. The daily human activities such as walking, jumping or running on the floor may lead to an uncomfortable feeling to the users when magnitudes of the vibration are uncontrolled. Comparisons of vibration serviceability criteria for design of timber floors among the European countries were conducted and the recommendations on vibration serviceability design of timber floors are proposed.

This examination offers the experimental analysis possibility of the reinforced-concrete core on effects of the horizontal load of seismic forces and the wind. These results are compared with the results obtained by FEM showing significant agreement.

As part of the project, structural elements of the bridge have been examined, based on which the existing amount of reinforcement and the level of damage to the bridge have been determined. We are planning rehabilitation and reconstruction of the bridge that has a total length of 11....
