Load bearing reinforced concrete structure of flat building
Ruber, Lukáš ; Kadlec, Jaroslav (referee) ; Girgle, František (advisor)
The aim of bachelor thesis was to design and assess reinforced concrete floor slab on a typical floor of flat building, which has been specifically selected second floor. Slab is locally supported by restraint concrete columns without collumns head. On the short sides is also reinforced concrete walls. These walls also serves as reinforcing. To calculate the internal forces were used calculation software RFEM 5. It was controled by method of summary moments with subsequent comparation of results. The Slab was rainforced by flexural longitudinal load-bearing reinforcement and around columns is placed shear reinforcement against slab extrusion by column. Part of this work is also drawing documentation of proposed solution.

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.

Kotvení předpjaté frp výztuže pro betonové konstrukce
Girgle, František ; Horák, David ; Štěpánek, Petr ; Laníková, Ivana ; Šimůnek, Petr
Non-metallic reinforcement has many advantages, but there are some areas of application that need to be resolved to improve the usage of FRP reinforcement in real conditions. One of the disadvantages of FRP reinforcement is its lower modulus of elasticity, which leads to greater deflections of structures and can also cause early propagation of cracks. The paper deals with the possibility of eliminating this problem by prestressing the reinforcement. It covers several problems related to anchoring and current anchoring methods used world-wide. The paper also mentions some drawbacks of these methods. In an effort to bypass these drawbacks a new anchoring method has been developed. It differs in the way longitudinal forces are transferred from the bar to the surrounding concrete. Basically, it is based on the addition of an additional anchoring member (cylinder) on the surface. This member is made of polymers so the whole system remains completely steel-free and very simple to produce. Before using the system in real structures a series of tests were performed and the results are presented. Also, some prestressed test panels were prepared and compared with standard panels.

Influence of standards changing on reliability of lightweight roof structures
Štěpánek, Petr ; Girgle, František ; Daněk, Petr ; Růžičková, Jana
This paper is intended to experts who work on the expert opinion for faults and breakdowns of lightweight roof load bearing structures. Changes of loading standards during the time play a fundamental role by redesigning of existing roof structures, especially of the lightweight structures. Significant differences are shown among the ČSN 730035 – 86, revise ČSN 730035 and ČSN EN 1991 in climatic loading (snow, wind). If any interventions into lightweight roof structures are planned it is necessary to pay attention to reliability of a load bearing structure. This paper describes some possibilities how to solve this problem.

The design of multi-storey building
Hardubej, Martin ; Girgle, František (referee) ; Švaříčková, Ivana (advisor)
The aim of the thesis is the design and assessment of selected elements of a new build multi-storey office building. The supporting structure of monolithic reinforced concrete skeleton is modeled SCIA Engineer and burdened set load cases and combinations. The outputs of the internal forces of the calculation program are dimensioned selected elements. Selected elements include locally supported slab, columns, column shoes, basement wall and footing still. The thesis is selected reinforced concrete elements assessed on the ultimate limit state. The output of this work is static calculation of individual elements. Another part of the output consists of drawings solved elements.

Load bearing reinforced concrete structure of flat house
Svoboda, Petr ; Krůpa, Pavel (referee) ; Girgle, František (advisor)
The main purpose of thesis is a static solution of load bearing reinforced concrete structure of flat house. The work contains an assessment of waterproof concrete building. The object is built under the groundwater level. Supporting structures are concrete slab, walls and columns. An assessment of these structures is realized in terms of first critical state- carrying capacity and second limit state- limitation of crack widths.

Design of reinforced concrete structure of administration building
Blažek, Jan ; Girgle, František (referee) ; Šimůnek, Petr (advisor)
The subject of this thesis is the project of the foundational board and of reinforced concrete walls of the underground office building with respect to the limit state of crack width. There is designed the execution of joints of various parts of the construction against infiltration of groundwater into the interior. The drawing documentation of designed parts is performed there. In the theoretical part, there are logged the design principles and implementation of the white tubs.

Selected structural detail of the reinforced concrete frame
Teplý, Jakub ; Matušíková, Anna (referee) ; Girgle, František (advisor)
The bachelor thesis solves and compares between them three methods (ČSN EN 1992-1-1, ČSN 73 1201, MC 2010) of punching shear slabs. In this thesis are the methods analyzed and compared with each other. In other part of thesis is solved and compares dependence of the required shear reinforcement areas on the various parameters, for example thickness of slabs or percentage of reinforcement. Conclusion provide an evaluation of the results and compared in charts course of dependence of the required shear reinforcement under the same conditions state.
