 Title of the thesis: Analysis of curved beams having the variable cross-section Summary: Sport buildings and structures like swimming pools, sport halls and gyms were always challenge for structural engineers, because there are relatively large spans with practically no possibility to use columns or other static structures, which can decrease the span, because it will significantly decrease space possibilities. The problem used to be solved mainly by steel truss systems in the past. Nowadays, when there is stress to decrease the usage of classic materials such as steel or concrete, or even to replace these materials by renewable resources. That's why timber has started to be used. Especially glued laminated timber, which has very good properties. The aim of my bachelor thesis was to make preliminary design of roof construction for a sport object -- swimming pool. I have done two options in my work. First option is based on a curved beam of circular shape having variable cross-section. These beams are made of glued laminated timber. Second option is pan construction of roof, however, all members have constant cross-section. The whole construction is also made of glued laminated timber. In first case the curved beam is two times statically indeterminate, since it is fixed in one end and there is pin support at another end. According to this I decided to use force method to determine internal forces. The construction is significantly more complicated in second case, so I decided to use my knowledge from the field of modeling in computer software called RFEM-Dlubal, in which I modeled the whole construction and complete protocol is attached in Attachment 1.
