Ultra-high performance concrete (UHPC) was evaluated as a potential material for future bridge deck designs. Material characterization tests took place to identify potential challenges in mixing, placing, and curing UHPC. Biaxial testing was performed to evaluate behavior of UHPC in combined tension and compression stress states. A UHPC bridge deck was designed to perform similarly to a conventional concrete bridge deck, and a single unit bridge deck section was tested to evaluate the design methods used for untreated UHPC. Material tests identified challenges with placing UHPC. A specified compressive strength was determined for structural design using untreated UHPC, which was identified as a cost-effective alternative to steam treated UHPC. UHPC was tested in biaxial tension-compression stress states. A biaxial test method was developed for UHPC to directly apply tension and compression. The influence of both curing method and fiber orientation were evaluated. The failure envelope developed for untreated UHPC with random fiber orientation was suggested as a conservative estimate for future analysis of UHPC. Digital image correlation was also evaluated as a means to estimate surface strains of UHPC, and recommendations are provided to improve consistency in future tests using DIC methods. A preliminary bridge deck design was completed for untreated UHPC and using established material models. Prestressing steel was used as primary reinforcement in the transverse direction. Preliminary testing was used to evaluate three different placement scenarios, and results showed that fiber settling was a potential placement problem resulting in reduced tensile strength. The UHPC bridge deck was redesigned to incorporate preliminary test results, and two single unit bridge deck sections were tested to evaluate the incorporated design methods for both upside down and right-side up placement techniques. Test results showed that the applied design methods would be conservative for either placement method. / Ph. D.

This diploma thesis deals with the problems of revitalization of historical objects. The theoretical part describes the technologies for static reinforcing and rehabilitation of vertical and horizontal bearing structures for a purpose of increasing the general stiffness of the object. As the practical part a static design project is made for reinforcing of the bearing walls and also for the general reconstruction of the slab. The slab is designed as the composite timber-concrete structure. The design project of the slab is economically compared with other variants. The designs are made for an existing object of the old restaurant in the village Velichovky.

The subject of this work is a new administrative building in Brno, district Brno – Stred. The aim of this work is to create documentation for realization. Building has twelve floors, while every floor is rotated by 5° relative to the previous floor counterclokwise. Final rotation between the first and the last floor is 60°. On the first floor there is a restaurant, on the next eleven floors there are administrative spaces. Building is without basement and has a single-layer flat roof. The foundations are made from a system of piles, which co-work with the waterproof foundation slab. Whole construction system is made from cast-in-place reinforced conrete.

This diploma thesis deals with the design and assessment of the two different variants of the steel structure of the business centre. The building is situated in Uherské Hradiště. The construction has several floors and the ground floor in the 1st floor is 32 x 32 m, it gradually extends evenly up in 2nd floor and 5th floor, to the total ground plan dimensions of 48 x 48 m. The building has 8 floors and its maximum construction height is 40 m. The supporting system of the structure is designed from S 355 steel, it consists of steel-concrete beams, dies and columns.

The theme of this diploma thesis is the design and assessment of a part of the underground load-bearing structure of the administrative center according to the source material. Emphasis is placed on the design, taking into account the waterproofness of the construction, the so-called white tank. This is ensured by the correct design of the concrete construction of the foundation slab and walls, taking into account the constructional details of the day and expansion joints, the concrete composition and the construction process.

This diploma thesis is processed in the form of design documentation for implementation of building. Solved building is a library in Veselí nad Moravou, cadastre unit Veselí-Předměstí. Building includes three above-ground floors and one underground floor. Floor plan is in shape of rectangular. Beside regular departments of library, study rooms, conference room and office parts, there is also a cafe and a bookstore. The structural system of a building is designed from cast-in-place concrete frame with filling from ceramic blocks Porotherm 30 Profi. Horizontal structural system is from cast-in-place reinforced concrete point-supported slabs. Part of facade is from glass and part is with contact thermal insulation system with mineral wool insulation. Roof construction is designed as flat green roof.

Master's thesis deals with the reinforcement and expansion of girder bridge (continuous bridge with three spans) across the river Jihlava in Ivančice and reinforcement on the load class A. This is done by using an additional external prestressing cables and composite monolithic slab. Amplification is verified by calculation of load capacity.

The diploma project is involved in structure design of multipurpose house. It´s four floor building with one underground floor and flat roof. Structure system is reinforced concrete skeleton. Ceilings are solved as reinforced concrete slabs, spot supported by columns with circuit reinforcing beam.

This diploma thesis involves design and assessment of the supporting elements of a two-storey family house ceiling construction. The slab components are pairs of beams and translations. I have choose two variants of solution for a long span elements. The first variant includes reinforced concrete elements only and in the second one prestress is used for beams, because of reducing construction height requirements. The basic model was evaluate by the calculation program Scia Engineer 2013, so I made 2D model of a slab in the program and joined 1D elements to the slab like a ribs. Selected prestress reduces a construction height, so it matches the desired appearance.

The diploma thesis deals with design and assessment of the main structure of the road bridge which leads the road I/55 over the highway D1. The thesis contains three designs of the construction. One design was chosen for detail solution. The thesis includes statical analysis, drawing documentation and visualization.
