Reinforced concrete structure of a multifunction building
Gregorová, Michaela ; Kostiha, Vojtěch (referee) ; Šulák, Pavel (advisor)
Bachelor thesis is focused on design of two way slab of multiple building, elaborating drawing of shape and reinforcement drawing of solid ceiling tile. Solved ceiling tile is located above 1.NP. Calculation of internal forces is performed by the method of spare continuous beams and compared with results from calculation program SCIA Engineer. Reinforcement drawing are drawn in program AutoCAD with superstructure Recoc. Next part this bachelor deals staircase, which leads from 1.NP to 2.NP, this it is connected to the solved ceiling. Next is assessed internal wall, which is made of brick elements and below it, proposed foundation construction. For calculations has been used norm ČSN EN 1992.
Design of reinforced concrete frame construction of a single-nave hall
Friedová, Lenka ; Šulák, Pavel (referee) ; Kostiha, Vojtěch (advisor)
The main part of the bachelor's thesis is the design and assessment of a prefacast girder of a single-aisle storage hall. The static solution is performed in the Dlubal RFEM 5.19 computer program. Verification of the correctness of the results is ensured by the simplified deformation method. The result of the work is a static calculation and drawing documentation, which is processed in AutoCAD software.
Design and assessment of selected structural members of reinforced concrete structure
Niesner, Jakub ; Čairović, Dorde (referee) ; Kostiha, Vojtěch (advisor)
This bachelor thesis deals with the static solution of the loadbearing re-inforced concrete structure of administrative three-storey building. The thesis deal with design and assessment of selected loadbearing elements, specifically reinforced concrete column, beam and cross reinforced concrete slab, above the ground floor. The structure is designed and checked for the ultimate limit state and usebility.
Behaviour of reinforced concrete columns confined with FRP wrap
Niesner, Jakub ; Čairović, Dorde (referee) ; Kostiha, Vojtěch (advisor)
Strengthening of reinforced columns confining by modern composite materials is effective method, allows quickly realized strengthening, without increase dimension of strengthening columns. Just like using reinforcing bars, is the mainly assumption for this method the multi-axis state tension and deducing confining pressure, which will increase strength of concrete. Improved of properties of confining concrete can be determined by using relationships, but there are considerably differences. This diploma theses, dealing with strengthening of circular reinforced columns confinement by external FRP fabric, compared approaches to design of reinforced concrete by confining and using the results of an analytical and numerical study to describe problem of confining concrete and compare factors influencing the final properties of the wrapped concrete.
Reinforced concrete structure
Kučerková, Kristýna ; Kostiha, Vojtěch (referee) ; Šulák, Pavel (advisor)
The bachelor thesis deals with the construction of a multifunctional building on three floors, where shops will be located on the ground floor and offices are designed on the second and third floors. The ceiling slab is designed as reinforced concrete locally supported by columns, reinforced in both directions. To calculate the internal forces used Scia Engineer 1.18. To verify the accuracy of the results was used manual calculation. In the work is solved board on first floor and inner column. The work includes drawings of the slab and column reinforcement. The building is designed according to ČSN EN.
Design of various ways of carrying out the ceiling construction of a family house
Klust, Vojtěch ; Šulák, Pavel (referee) ; Kostiha, Vojtěch (advisor)
Bachelor´s thesis deals with the design of floor structure of detached house made in three variants. In the first variant floor structure is made by reinforced concrete two way slab. In the second variant floor structure is made by prefabricate prestressed concrete floor slab SPIROLL. The third variant is filigree floor slab which are then concreted. The thesis includes a structural design as well as drawings, All calculations were performed in accordance with applicable standard.
Design of concrete structures using modern composite materials
Badány, Kristián ; Januš, Ondřej (referee) ; Kostiha, Vojtěch (advisor)
In the first part, this work deals with basic information about non-metallic reinforcement and its general design, in the second part the prefabricated supporting wall is assessed. The support wall is designed in several variants: in the first variant for classical reinforcement reinforcement and in other variants it is for composite reinforcement. The entry of the support structure is the same for all variants. Calculation is processed by Fib Bulletin No. 40 and complies with ČSN EN.
Strengthening reinforced concrete column confined by FRP fabric
Kostiha, Vojtěch ; prof. Ing. Alois Materna, CSc., MBA (referee) ; Bilčík,, Juraj (referee) ; Štěpánek, Petr (advisor)
The doctoral thesis deals with the strengthening of reinforced concrete columns by FRP fabric wrapping. Its aim is to describe the principles of confinement based on the analytical study, numerical simulations and the results of the experimental program. The description of the confinement philosophy is made with respect to the type of FRP material used. It was therefore possible to present a design process of confinement, which accurately predicts the behaviour of the confined columns. At the same time, some effects limiting the effect of confinement (e.g. the method of wrapping, the number of FRP fabric layers, the slenderness of the element, etc.) are included in the design. The dissertation also presents basic information about FRP material and its properties and gives an overview of design approaches of the FRP confined columns. The dissertation also pointing out the shortcomings of the design code ČSN EN 1992-1-1. The stated example highlights the significant variation in properties of confined concrete determined by selected approaches. This variation of properties complicates the design of this strengthening method. The experimental program was used to verify the basic principles of confinement and, through high columns, allowed a description of the behaviour in almost the whole range of interaction diagram. The conclusions of the work provide information on possible future research direction.
Prefabricated reinforced concrete hall with crane track
Velecký, Tomáš ; Kostiha, Vojtěch (referee) ; Požár, Michal (advisor)
This bachelor thesis is focused on static solution of prefabricated reinforced concrete hall with crane runway. Specifically, the cross-section of the hall, which consists of rectangular columns and a T-profile reinforced concrete truss, is solved here. The load on the structure is transmitted to the subsoil by calyx-reinforced concrete pavements. The bachelor thesis deals with the design and assessment of individual structural elements. Elements are dimensioned according to ČSN EN 1992-1-1: Design of concrete structures - general rules and rules for building structures. In the drawing part of the bachelor thesis are drawn drawings of the assembly of parts, shapes and reinforcement of individual parts.
Static solution of reinforced concrete structure
Mašek, Petr ; Kostiha, Vojtěch (referee) ; Zlámal, Martin (advisor)
This diploma thesis deals with study of feasibility of waterpark monolithic reinforced concrete structure with roof terrace. This structure has one underground floor, which has water park utility function and two above ground floors. On the roof is terrace with grass, mobile bar and with space to relax. Subject of this diploma thesis is the main loadbearing frame, which has span 32 m. The structure is assessed according to limit states of valid norms and also takes into account construction stages and time dependent analysis. The structure is calculated on beam and slab-plate structural models. Structural analysis and general drawings are done.
