Analýza účinků pohyblivého zatížení na prutové konstrukci

Abstract

Thanks to the rapid development of computing software, static calculations and their modeling are becoming faster and more accurate. It was the creation of an application for calculating static quantities and extreme load effects on the bridge construction, that was the first inspiration for the creation of this bachelor’s thesis. The intention of the bachelor’s thesis was to create an application for calculating the extreme effects of the moving load of a simple bridge construction. The computing application was created in the MATLAB software environment using the MatLab App Designer. In the application, it is possible to generally define the bridge structure with the defining of a moving load in the form of a system of point forces. Moving load in the application can be defined as a generally specified system of forces or define it by selecting standard vehicles with specified parameters of point forces and their distances. The output of the application is a graphic representation of an animation of the movement of the vehicle after the bridge construction with the calculation of static quantities and internal forces. Another possible output is the graphically depicted packaging curve of the moment in the movement of load with the determination of the load state in which the extreme effect occurred. This course of calculation is described in a sample example with verification of the correctness of the results.
