This diploma thesis is dealing with frame multi-storey garage structure, mainly with its slab. According to the assignment there was made a parametrical study. It contains the comparision of three construction versions: solid slab, slab with void formers Cobiax and prestressed concrete slab. At the chosen variant the 3D mathematical model, which was created in software Scia Engineer, was specified and the construction was designed according to ultimate limit state and serviceability limit state. The outlet of this thesis is structural design and drawings with all designed items

The aim of diploma thesis is to design a made-up bridge construction over the road network.There were made three studies of bridging which were compared consequently. Two-joint ginder without haunched was selected as the most suitable option and it was designed in details. The construction was assessed according to the ultimate and serviceability limit state.

The diploma thesis deals with the design of a reinforced concrete floor structure above the 1st floor of a two-storey pavilion of a spa complex. It is a point-supported slab with the use of prestress. The design is converted with respect to the required fire resistance of structures. The analysis of internal forces is performed by manual calculation using the method of spare frames and using the computational software RFEM 5.23, which uses the finite element method. The design is made according to the group of standards ČSN EN.
