Optimization of the Wire Drawing Process
Kabilka, David ; Světlík, Radim (referee) ; Řiháček, Jan (advisor)
The aim of work is to present and analyse assessment of the current state and at the same time the proposal of adjustments to the technology or parameters, the introduction of the wire into the drawing machine. The problem arises when the introduction of wire with a diameter of 14 mm from the material CK 67 to the drawbenches Schumag. If we introduce the wire into the drawing machines with two primary beams leads to a buckling of the wire and pack between the drawing die and the boot device. For the introduction of wire are used hydraulic boot collets, which are controlled semi-automatically. In connection with professional studies and on the basis of the calculation, simulation and practical experiment have been identified the conditions allowing the current method of deployment of wire to use.

Static design of the structure composed of combination of steel and structural glass
Potůčková, Simona ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The objective of the bachelor thesis is to design the load-bearing construction system and its cladding made of a combination of steel and structural glass and to verify its sufficient resistance. The object has rectangular floor plan with dimensions of 7,5x10,5 m and and its total height is 24,5 m. The building is located at the suburban area of the city Ostrava, precisely Ostrava Poruba. The construction is composed of a ground floor and six upper floors. The main load-bearing system consists of steel frame formed by six tubular columns connected beams and sway bracings ensuring the spatial rigidity of the structure. The object was designed according to currently valid standards using ULS and SLS verification.

Storage hall
Osyková, Martina ; Šulák, Pavel (referee) ; Laníková, Ivana (advisor)
The master thesis ´´Storage hall” deals with designing of selected elements prefabrikated skeleton hall. Discussed elements are truss, beam, girder, column and prefabricate footing. Within above mentioned elements was carried out static analysis, design of reinforcement and reinforcement drawings. Analysis of internal forces for columns and prefabricate footing was carried out with usage of the program Scia Engineer, 3D model of the whole object was created. Analysis of internal forces for the rest of elements was carried out with help of manual calculation. Those elements were designed with consideration of ultimate limit state. Serviceability limit state assessment was carried out within the truss.

Static analysis of reinforced concrete roofing of platform
Popovič, Tomáš ; Strnad, Jiří (referee) ; Zich, Miloš (advisor)
The thesis deals with the static solution of reinforced concrete roofing of bus platform. It is a monolithic reinforced concrete frame structure, which is consisting of circular pillar and girder. The girder has the general shape. The board is double-sided embedded into girder. The loads acting on the construction are transmitted to the foundation soil using reinforced concrete foundation blocks. The content of this thesis is based on the dimensioning of individual elements of the support structure according to ČSN EN 1992-1-1. These elements are dimensioned for the ultimate limit state. The main outputs of this static calculation are drawings of shape and drawings of reinforcement.

Wire Drawing Technology
Štys, Michal ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The paper presents current research on the technology of wire drawing with focusing on the analysis of process factors, their calculation and influence on the process itself. The research describes drawing methods and technological process of wire drawing. The work also deals with geometry and die materials and their effects on process quality and tool wear. Subsequently this thesis analyses currently used machines and their advantages and disadvantages. As well as their suitability for use depending on the materials of the drawn wires and economic profitability. At the end of the thesis, unconventional methods of wire drawing and their future development estimation are presented.

New family house in Poříčí nad Sázavou
Figuli, Juraj ; Perla, Jan (referee) ; Koláček, Jan (advisor)
This diploma thesis involves design and assessment of the supporting elements of a two-storey family house ceiling construction. The slab components are pairs of beams and translations. I have choose two variants of solution for a long span elements. The first variant includes reinforced concrete elements only and in the second one prestress is used for beams, because of reducing construction height requirements. The basic model was evaluate by the calculation program Scia Engineer 2013, so I made 2D model of a slab in the program and joined 1D elements to the slab like a ribs. Selected prestress reduces a construction height, so it matches the desired appearance.

Design of strengthening of the concrete structure from 1928
Bažantová, Lenka ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The bachelor’s thesis is focused on assessment of the existing construction four-storey building. The supporting system consists of cast-in-place concrete frame. The aim of this work is to assess the support structure for the expected loading of the resulting change in use of buildings for residential or commercial purposes. The subjects of assesment are columns, beams, girders and floor slab. In another part of work is suggested by reinforcement of non-conforming elements. The work includes the development of stroctural analysis and reinforcement drawings of reconstructed elements.

Čihák, Tomáš ; Kraut, Jan (referee) ; Šulák, Pavel (advisor)
This master thesis deals with a draft of precast concrete frame structure on the case of gymnasium building. The major part of this work are transversal and longitudinal frames, consisted of footings, columns, girders and precast floor slab. Other parts of the building are not solved. Thesis consists both static calculations and drawings.

Medical center Hlinsko
Pilný, Ondřej ; Burianová, Lenka (referee) ; Kacálek, Petr (advisor)
This diploma thesis deals with the design and elaboration process of a project documentation of medical center in city Hlinsko. New building is situated in the northern part of the city in the area determined for constructions of public infrastructure. It´s a four-floor object with partial basement and slant mansard and flat vegetative roof.Object is based on foundation strips and footings made from reinforced concrete.The bearing and internal walls are designed from KALKSANDSTEIN lime sand blocks.The beams and collums are used in the placed designed with open disposition.The ceiling in 1.PP is designed as reinforced concrete for securing fire safety.The rest od ceiling constructions is designed from prestressed concrete panels SPIROLL,with exception in 4.NP,where the ceiling constructions are made from solid roof system YTONG KOMFORT,which is layed on frame system made of steel and reinforced concrete.The peripheral walls of 1.PP are made from lost formwork, which is insulated with extruded polystyrene.The walls in floors above ground are insulated with combination of external thermal insulation system (ETICS) and ventilated facade with CEMBRIT SOLID and PATINA facade cladding panels. The building is functionally divided into several part.Cafe, pharmacy, ambulance and medical center, each with it´s own entrance.Pharmacy is equipped with shop, medicine mixer and storage.Ambulance is equipped with garage slots, background for employees, room of crisis preparedness and operating center.Medical centrum is equipped with emergency, RTG, operating theater, rehabilitations and other types of examination rooms.Each examination room is equipped with waiting room.For more comfort the center has a background for employees.The whole object is designed with forced air exchange. Designed object is barrier-free.In front of the building is situated parking slots for cars, motorbikes and ambulances.Total number of slots is 74 places, which 5 is designed for disabled people.
