Reinforced concrete slab of the administrative part of the depository
Jirků, Jan ; Strnad, Jiří (referee) ; Požár, Michal (advisor)
The bachelor's thesis focuses on the design and assessment of a reinforced concrete locally supported monolithic slab below the first floor of a library depository. The thesis also includes the design and assessment of a column and a prefabricated staircase. The calculation of internal forces was performed using the finite element method in the SCIA Engineer program, and its accuracy was verified by a manual calculation using the method of moment summation. The slab was assessed for ultimate limit state and serviceability limit state. Finally, based on the structural calculation, reinforcement drawings for the individual structures were prepared.

Reconstruction of a multi-storey building
Krpec, Pavel ; Zlámalová, Pavlína (referee) ; Strnad, Jiří (advisor)
The bachelor thesis is focused on the design of structural protection and structural modificati ons of a brick apartment building with massive failures. The thesis deals with the justification of the cracks in the gable wall and the overall structural securing of the building. The work inc ludes an accompanying report to the structural calculation, a technical report, a structural calculation and drawings. RFEM 5 and IdeaStatiCa were used to calculate the internal forces. The drawing documentation includes drawings of the prestressing cables, the reinforced concrete tower and the steel girder.

A bridge with one field over a watercourse
Pylypenko, Jevhenij ; Požár, Michal (referee) ; Strnad, Jiří (advisor)
The thesis focuses on the design of the superstructure of a new concrete bridge, which replaces an old substandard construction. The bridge should serve for passing roadway across the river Šlapanka, in village Mírovka, Kraj Vysočina. The static system of new construction is a one-span post-tensioned slab which is simple supported on edges. Span length of the superstructure is 17,5 meters. From three variants of concrete slab cross-section, a trapezoidal-shaped one was chosen. Concrete slab was assessed by the ultimate limit state and service limit state according to recent standards (Eurocode). The preliminary design of post-tension was processed according to standards (CSN).

Cast-in-place tank of sewage plant
Čožík, Martin ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The thesis deals with the design and assessment of monolithic reinforced concrete structures tanks and wastewater treatment plants in accordance with applicable standards and drafting drawings. The tank is divided into individual solved parts: base plate, walls and ceiling plate. These parts are designed according to the ultimate limit states and serviceability. Resolves an assessment of the foundation structure according to the second geotechnical categories.

Concrete ribbed slab
Dvořák, Vít ; Perla, Jan (referee) ; Strnad, Jiří (advisor)
The bachelor thesis deals with a design of monolithic reinforced concrete, line supported and cross reinforced slab and a design of supporting reinforced concrete ribs. The plan of the slabs is rectangular and one time bent. The content bachelor thesis is calculation and design of reinforcement of slab and ribs. For the calculation was used software Scia Engineer 14 and was checked by manually calculation. The slab is located in the first floor of polyfunctional house. Other parts of the object are not covered by the thesis.

Design of precast foundation for machinery
Šandor, Peter ; Zich, Miloš (referee) ; Strnad, Jiří (advisor)
The bachelor‘s thesis main focus is the design of reinforced concrete foundations. The purpose of this thesis is to design the height of the foundation and the dimensioning of the reinforcements. It also deals with tilting and carrying capacity of the foundation gap. Mechanical drawings of the reinforcements and the shape of the foundation are also part of this thesis

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.

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.

Concrete flat slab supported by columns
Macháček, Jan ; Strnad, Jiří (referee) ; Perla, Jan (advisor)
The aim of this bachelor’s thesis is a structural design of a reinforced concrete point-supported slab for the second floor construction of a hospital. Software RFEM was used for modeling of internal forces, the results were verified by equivalent frame method and moment coefficient method. According to the RFEM results a tension reinforcement and slab shear reinforcement were designed. The deflection was manually calculated. Afterwards, a reinforcement drawing was made. The calculations correspond with ČSN EN 1992-1-1 a ČSN 73 1201.
