This dissertation analyses precast walls made of plain concrete and lightly reinforced concrete. The main focus is on evaluating the concrete and the reinforcement of precast concrete wall panels in relation to manufacturing, handling, and final phases. The dynamic load component of panels during handling was measured in controlled tests. Shrinkage measurement was implemented during the maturing process of the concrete used for panel manufacturing. The value of cohesion was observed between the reinforcement and the concrete that had matured for 20 hours. It was also looked at the value of adhesive strength between the panel surface and the casting table. The experimental study checked the panel strain during removal from the casting table, the panel compression during a truck ride over an obstacle, and the tension in the carriage strap during panel transportation to the building site. Mathematical formulas were drawn up to validate the concrete and reinforcement of wall panels made of lightly reinforced concrete. Those mathematical formulas were applied in a specific panel wall design and the results were verified by nonlinear numerical models.

The aim of this work is to optimize the acoustic nondestructive method (NDT) Impact-Echo (IE) as a complementary diagnostic tool for the assessment of concrete structures exposed to high temperatures. Commonly used diagnostic procedures for concrete structures affected by fire are most often limited to in-situ core drilling and subsequent testing of the drilled holes by destructive testing. The Impact-Echo method allows non-destructive testing of variously degraded test specimens and concrete structures, but its use for the assessment of temperature-degraded cementitious composites is hardly ever used in practice. Many studies suggest that Impact-Echo is one of the most suitable non-destructive methods for assessing the rate of degradation by elevated temperature. The dissertation work consists of three main stages, where the first stage is devoted to the production of test specimens of different mixtures and their subsequent degradation by elevated temperature and testing by the IE method and by reference destructive and non-destructive methods. The second stage consists of manufacturing a reinforced concrete element with built-in thermocouples and its subsequent inhomogeneous degradation by a local source of elevated temperature. The controlled degraded element thus prepared contains all grades of thermally degraded concrete tested in the first stage. Subsequent testing consists of verification of standard procedures in the field of acoustic NDT with simultaneous use of experimental modal analysis. In the third stage, the objective is to interpret the measured data from both previous parts, to verify whether within the closed element temperature-degraded areas can be distinguished from one another, or the degree of thermal degradation of concrete. Based on these results, the optimal testing procedure was determined and the basic assumptions for the creation of degrees of damage of the concrete by increased temperature were determined.

The building of cultural center is located at the Brno dam lake. It contains two multifunctional halls, coffee. Roofs are walkable. First roof rises up and ofers overlook. The other ramps down and includes stairway useful as an amfitheater and a relaxation area.

This master´s thesis studies qualities of aerated concretes, is monitoring influenece concrete composition, quantity of aerating admixture and plasticized admixture on the durability of concrete. It is monitored especially air flow and his influence on durability on concrete. In theoretical part are explained mechanisms of damage concrete, phenomena, which influence compressive strength of concrete and then there are the results of resistance against the influence of chemical defrosting substances. In experimental work were designed, mixed and tested recipe of concerete. We investigated different atribute, especially resistance of the chemical defrosting and air flow in hardened concrete. The result of master´s thesis is effect of flow air in concrete on the durability.

The aim of this thesis is design and programming of a numerical model of shrinkage of cement composites using physical discretization and solved by parallel processing. Introduction is about the shrinkage of cement composites and explanation of terms, which are included in this thesis. The main part deals with programming of the output model, the procedure of its creation and the results of simulations.

Subject of this master thesis is a flyover bridge over the road II/434 and flood-land. As a load-bearing construction is designed two-beam structure. Traffic loads on this structure are considered according to standard ČSN EN 1991-2. The structure design is based on resultant stressing according to standard ČSN EN 1992-2.

The economic cost of a static design is nowadays very often the decisive factor during a tender. This work deals with the economic cost of designing the ceiling construction of a polyfunctional building. The work shows three design options regarding the second boundary condition. The decisive factor is the deflection under the masonry constructions. The deformation of the ceiling construction cannot be allowed to cause cracks in the masonry partitions. The aim of this work is the comparison of the economic cost of the possible design options.

The subject matter of my Diploma thesis is the project of a new golf club. The building has one floor and is covered by a flat mono-coated roof. Spacious terraces accessible from first floor are the integral parts. Vertical load bearing and non-load bearing walls are designed from Porotherm walling system. Horizontal load bearing ceiling constructions are designed from an prestressed ceiling panels Spiroll. Foundations are designed reinforced concrete. The building is divided into two separate operating units. The project emphasizes the layout plan, thermal technical properties and safety in use.

The diploma thesis describes the design of curved, pre-stressed concrete bridge over the highway D1. A variant, that is chosen for detail analysis, is a spine girder construction as a continuous beam with 3 spans. The thesis solves the construction to limit states according to applicable European standards (Eurocodes). There are developed clear and detailed drawings and visualization of the bridge.

This document describes the design of the roof structure for the dimensions of the rink. It was designed and evaluated three roofing solutions – steel truss structure, concrete arch with external prestress and prestress truss roof girder with concrete roof panel. One option was selected – prestress truss girder. This variant has been further developed. In the beginning was drafted several proposals geometry respecting the demands on the type of construction. Within the static calculation was created a mathematical model of the structure of the program Scia Engineer. Using this model were obtained values needed for the assessment of individual elements of construction and design assessment as a whole for the ultimate limit state and usability. According to the proposed geometry and opinions parts of the structure was drawing documentation structure as a whole and individual parts of the structure solved in this thesis. The last proposal was visualized structures together with the phases of the construction by program ArchiCAD and rendered by program Artlantis.
