Globální statická analýza lehké ocelové haly se zaměřením na spoje nosných tenkostěnných prvků

Abstract

The present dissertation deals with the analysis of a selected clinching method with a focus on application in thin-walled elements of building structures. The thesis consists of 3 main parts. The first part of the thesis is focused on the research of clinching technology and its potential for structural engineering. The next part of the thesis is dedicated to physical experiments of individual clinch connectors, but also of the selected structural design representing the elements of the building structure. A total of 100 physical experiments of different nature are carried out. The outputs of the physical experiments are validated in detail using sophisticated numerical analyses to increase the efficiency of preprocessing. The numerical validations also include an analysis of the suitability of finite elements, methods of modelling joints and the use of material models. Furthermore, a method for simplified but very efficient modelling of bolted and clinch connectors is presented. The output of the physical experiments, which are validated by numerical analyses is a summary of the findings that leads to recommendations for designers of steel structures and practical use in steel construction applications.
