Strengthening study of a reinforced concrete plain girder
 Jalůvková, Lucie ; Pinkas, Karel (referee) ; Svoboda, Adam (advisor)
The subject of my bachelor thesis is to analyze existing reinforced concrete plain girders according to the current standards with a variety of strengthening solutions. The roof girders are located in industrial building in Lanškroun in the Pardubice Region. Its original design dates back to 1998, therefore the roof girders were designed according to the standards valid at that time. The strengthening of the roof girders will be designed using additional external prestressing and composite reinforcement followed by verification of the ultimate limit state, serviceability limit state and fire resistance. A digital model for checking the calculation was created using software Scia Engineer. For the verification of the composite reinforcement software Sika CarboDur was used.

Strengthening of roof girders in production hall
 Wawreczka, Karel ; Strnad, Jiří (referee) ; Klusáček, Ladislav (advisor)
The aim of my bachelor’s thesis is strengthening of girder roof construction in a production hall. The roof girders were designed 18 years ago in accordance with the Czech standards valid at that time. All the girders are now recalculated according to valid European norms. It is suggested to use prestressed cables guided along the girder construction. Because of the lack of space around the front of girders, it is designed to use prestressing from in the middle. In order to design the cable geometry and the biasing force, it was crucial to take into account shear resistance as well as constraining compressive stress in the concrete. Calculation of the effects of load is carried out by Scia Engineer 2015 computer software whereas Excel has been used for all the other calculations.
