yes / A mechanism analysis based on the upper-bound theorem of concrete plasticity for monolithic concrete joints without transverse reinforcement is presented. Concrete is modelled as a rigid–perfectly plastic material obeying modified Coulomb failure criteria. Existing stress–strain relationships of concrete in compression and tension are comprehensively modified using the crack band theory to allow for concrete type and maximum aggregate size. Simple equations for the effectiveness factor for compression, ratio of effective tensile strength to compressive strength and angle of concrete friction are then mathematically developed using the modified stress–strain relationships of concrete. In addition, 12 push-off specimens made of all-lightweight, sand–lightweight and normal-weight concrete having maximum aggregate size between 4 and 19 mm were physically tested. Test results and mechanism analysis clearly showed that the shear capacity of monolithic concrete joints increased with the increase of the maximum aggregate size and dry density of concrete. The mean and standard deviation of the ratio between experimentally measured and predicted (by the mechanism analysis shear capacities) are 1·01 and 0·16 respectively, showing a closer prediction and less variation than Vecchio and Collins' equation, regardless of concrete type and maximum aggregate size.

Although the application of surface treatments on bridge decks is expected to positively impact bridge deck condition, the effectiveness of specific surface treatments on extending bridge deck life has not yet been quantified on Utah bridge decks. Therefore, the objectives of this research were to develop and analyze deterioration curves for bare concrete bridge decks and decks with specific treatments commonly used in Utah. The scope of this study was determined by the types and extent of electronically available data, including selected static inventory information; maintenance, rehabilitation, and reconstruction histories; and National Bridge Inventory (NBI) condition ratings for the bridge decks. Bridge deck selection criteria and analysis procedures were developed to enable evaluation of the effects of surface treatments on bridge decks in Utah. Characteristics of a typical bridge were defined, and a list of typical bridges was produced to minimize potentially confounding effects of atypical bridge characteristics in comparisons of deterioration curves for monolithic concrete decks, decks with a bituminous overlay, decks with an epoxy overlay, and decks with a latex-modified concrete overlay. Climatic differences were taken into account by grouping bridges not only by overlay type, but also by Utah Department of Transportation region, which was used in this research as a general surrogate for latitude. Individual bridge deck deterioration curves were then combined to generate average deterioration curves aligned by deck construction time and average deterioration curves aligned by deck treatment time. To at least partially account for the potentially different effects of different treatment times, the bridge groups involving overlays were divided into two treatment time categories, early and late, for analysis. The average deterioration curves aligned by deck construction time suggest that certain treatments applied at certain times can achieve average NBI ratings greater than those for monolithic concrete during selected years of bridge deck life. The average deterioration curves aligned by deck treatment time suggest that certain treatments applied at certain times can achieve improvements in NBI ratings that correspond to apparent increases in bridge deck service life. Primarily because the NBI rating system is based mainly on visual inspection, the full benefits of early applications of surface treatments are not apparent in the results of this research. Supplemental perspectives may be gained about the performance of specific surface treatments by evaluating bridge deck deterioration in terms of delamination, half-cell potential, and chloride concentration, for example, which are direct measures of the deterioration process typically experienced by concrete bridge decks in Utah.

The theme of my dissertation is creation of technical dokumentacion for the Apartment Building with Commercial premises. The building is three storey. In the 1st floor is located a shop and garage, in the 2nd floor and 3rd floor apartments. The building is designed as a monolithic concrete frame contruction with flat roof. Peripheral walls are sandwich ones made from ceramics masonry and contacts thermal insulation systém.

Diploma thesis solves the new building in Nitra. The building is located on Kmeťová street. The building has four floors above ground and one underground and the Garage. 1st floor is clinic. Other floors are for apartments .. The structural system is a monolithic reinforced concrete and brick. The building is covered with a flat roof. Foundation structure consists of reinforced concrete block.

This thesis covers brand new detached indoor pool with one underground and one above ground floor, which is designed for a maximum capacity of 120 people, with two swimming pools, a children's swimming. The building is designed with a flat rectangular roof insulation. Envelopes are ventilated, insulated, bearing part consists of reinforced concrete. The pool hall make up the majority of the building envelope glass facade. Facilities for employees is located on the first basement floor. All technologies for cleaning pool water, air conditioning, boiler, facilities for maintenance are located on the first basement floor. Chimneys are stainless steel, placed on the outside of the building. The finish floors are ceramic tile. Pool bath is designed as a so-called white bathtub. The supporting structure of the ceiling above the pool hall beams are post-tensioned concrete.

The topic of the diploma thesis is the design of monolithic concrete structure CERIT in Brno. There are designed three preliminary variants of the concrete structure for the problematic place in the building. Selected variant is developed in detail design (the concrete wall). The solution comprises statical analysis, text section and drawing documentation.

The work focuses on the design and assessment of selected structural elements of one overground floor monolithic concrete structures and staircases. All calculations are done in accordance with Eurocode 2.

The theme of master´s thesis is treated newly built medical facility - polyclinics in Piestany. This work aims to develop project documentation for building construction. The building is partial basement four- storey. The building is designed as a monolithic reinforced concrete frame with infill exterior walls of ceramic blocks Porotherm. The ceiling structure consists of reinforced concrete slabs. The facility is designed flat and pitched roof with single-layer vegetation. In the building surgery for doctors, nurses, dressing room, pharmacy, cafe-bar, administrative part. In the basement there is a technical background as an engine room ventilation, boiler room, storage. Outside, next to the building is a terrace, which is for cafe-bar customers and also there is a playground.

The aim of diploma thesis is a design and an assessment of selected structural elements of one floor in monolithic concrete structures serving as covered parking for an apartment house. Software RFEM is used here to calculate internal forces. The thesis also includes manual calculation of internal forces and comparison with software results. It also includes drawings of proposed solution. All calculation are done in accordance with Eurocode 2.

This master´s project deals with design of an office building nearly zero energy standard. My master´s project consists of three parts. In the first one I work on technical design of the office building. It is a three-storey building with partial basement. Vertical load-bearing system is partially made from monolithic concrete walls and partially from clay blocks walls. The horizontal load-bearing structures are made of monolithic concrete slab. All roofs are designed as flat roofs. In second part I design all technical equipment in this building. In the last part I compare three types of roof, photovoltaic power plants and evaluate their environmental impact. First type of PV power plant is made by monocrystalline solar cell, second one by polycrystalline solar cell and last one by monocrystalline solar cell with battery system. Environmental impact of these systems is evaluated in Open LCA software. All structures comply with the valid standards and regulations.
