Design of concrete structures with FRP reinforcement
Januš, Ondřej ; Girgle, František (referee) ; Štěpánek, Petr (advisor)
The diploma thesis presents design of construction with FRP reinforcement. Including design process of cross-section with FRP reinforcement exposed to bending moment and shear force at ultimate limite state according to given standards and guidelines. Long term physical and mechanical properties of FRPs are taking into account. There are also compared load capacities of cross-section exposed to combination of bending moment and axial force, which were designed according to mentioned standards. In another part of diploma thesis there is a design of construction (precast gatehouse) with FRP reinforcement and steel reinforcement with ordinary and lightweight concerete.

Use of composite materials for the design of concrete structures
Vašátko, David ; Januš, Ondřej (referee) ; Girgle, František (advisor)
Composite reinforcement tends to be perspective material for construction reinforcing. Its application is suitable especially for areas with high level of environmental stress, or environment loaded with physical phenomenon. This thesis is focused on inner FRP reinforcement. Theoretical part deals with mode of production, types of used materials, behavior depending on stress type and different approaches towards designing for short-term or long-term load capacity of composite reinforcement. Practical part includes assessment of precast element, dealing with requirement of non-magnetic reinforcement. Assessment is designed with two alternatives, each of them differing in type of main load-bearing reinforcement. First one works with stainless steel reinforcement, the second one with GFRP one.

Fire station
Wrana, Lukáš ; Šteffek, Libor (referee) ; Ostrý, Milan (advisor)
The subject of this thesis is to create a project documentation of the design of new construction of fire station in Šumperk. The fire station is designed according to ČSN 73 5710 as a C type station that will be used by professional fire brigade of Olomouc district. The object is structurally divided into two parts - a masonry building, and a reinforced concrete frame. The administrative part of the building together with the base of the fire brigade, technical room, and a fire tower are designed as a masonry building made of Ytong cellular concrete units. One of the parts is designed as a two-level object, while the technical room and the fire tower are designed as a sigle-level object. The circumferential masonry is insulated by contact thermal insulation system. The floor construction is made of Spiroll prestressed floor slabs. The roof is designed as a warm flat roof. The garage is a single-level building with built-in structure of storerooms in part of the garage. The precast reinforced concrete frame is set on foundation pads and foundation sills. The horizontal and vertical supporting structure consists of reinforced concrete parts – columns, Spiroll floor slabs, floor girders, sway frames, purlins and small purlins. The whole object is covered by a warm flat roof. The external cladding consists of PUR isolating sanwich panels.

Analysis of the Equivalent Diagonal Strut Width of Infill Shear Wall with an Opening
Šimek, Ondřej ; Zich, Miloš
The subject of the article is a comparison of behavior of a precast reinforced concrete infill shear walls with an opening with different types of reinforcement. These are the walls that can ensure stiffness of the frame structure against horizontal load. Studied walls with an opening represent cases of how the wall can be reinforced prior to the implementation of an additional opening. The influence of the so called “sleeping reinforcement” is studied. This is a reinforcement that would take effect only after the additional opening has been made. Based on the already published results of the experiment and subsequent verification with numerical models, a parametric study is performed, where the influence of an opening size in these infill shear walls is studied on their load - bearing capacity and stiffness. Lastly, a comparison of the obtained results with available literature is made.
