Nesse contexto, esse trabalho propõe determinar a influência das características dos elementos construtivos – portas e circulações entre unidades habitacionais – no isolamento ao ruído aéreo do conjunto de paredes e portas separadas pelo hall de entrada. Primeiramente foi realizado um estudo piloto que envolveu ensaios em campo feitos em diversas obras. Com isso, foram escolhidos três prédios e executados uma série de ensaios de desempenho acústico em campo, abrangendo diversas situações. Também foram usados artifícios para a vedação das frestas das portas, a fim de verificar a melhora do desempenho do sistema. Os resultados obtidos apontam para a perda de desempenho acústico com o aumento das frestas entre a folha da porta e o piso. Foram encontradas também relações com tempo de reverberação dos ambientes de circulação e a distância entre as portas de entrada das unidades habitacionais. / Sets of walls and doors separated by condominium corridors in residential buildings started having their acoustic performance evaluated when the Brazilian standard NBR 15575 came into effect, which concerns the performance of buildings. In this context, this study proposed to determine the influence of the characteristics of constructive elements – doors and corridors between residential units – on the airborne sound insulation of the set of walls and doors separated by the entrance hall. First, a pilot study was conducted based on tests performed on many buildings, but it was noted that a deeper study on the subject would be required. Thereby, three buildings were chosen and a series of acoustic performance tests was executed, covering several situations. Maneuvers for sealing door gaps were used as well, in order to assess the performance gains of the system. The results indicated loss of acoustic performance when there were more gaps between the door leaf and the floor. Moreover, relations were found regarding the reverberation time of the corridors and the distance between the entrance doors of residential units.

The topic of the Diploma thesis is a design of the New train station in Brno. The plot is located on the boundary of three city districts – Komárov, Štýřice and Trnitá. This area includes the railway structure for the new train station and also its public spaces, which are very close to the river Svratka. The railway structure is designed as bridge construction, that rises all platforms and rail tracks to 7,65 metres above the ground level. So all of the railways do not become a barrier in the city. The main concept extends a longitudinal axis of the city boulevard through the train station, which creates a high-rise building in the southern part of the plot. This axis is written not only to the layout but also to the roof design. The train station includes two underground levels, ground floor and first floor. Underground levels consist of P+R parking, deliveries only area, technical facilities and subway terminal. The ground floor is the main traffic centre. There is an entrance hall, shopping area, bus terminal and public corridors. The first floor includes platforms for train departures and arrivals. There are also public spaces in the entrance hall. The basic structural system consists of two parts. The first part is a massive reinforced concrete structure of the railway bridge deck and all underground levels. This structure is based on reinforced concrete foundation pads with drilled piles. The second part is a steel frame structure of the roof. That includes steel columns and truss girders for the structure of the lower area. The higher part of the roof is designed as a steel-truss bridge with the characteristic profile. The new train station supposes to create a new gate to the city of Brno, that connects contemporary districts with the historical city center.

This study addresses the design of a new cultural center in the Moravian Square – a polyfunctional object with a great concert hall, a small multifunctional hall with operating and technical facilities, parking, customer services for visitors, and areas for employees and musicians. Also, a restaurant & cafe is a part of this proposed project. New space replaces the unsatisfactory conditions of the current residence of Brno Filharmony in Besední dům – too small, unsatisfactory acoustics, and complicated operation. The cultural center, also, serves as a congress center that is currently missing in Brno - a city of trade fairs and exhibitions. The proposition respects the existing character of the park. The capacity of the new proposed design is from three-quarters underground, and therefore makes a way (nebo „space“) for greenery and pedestrians. The designed object consists of one ground and two underground levels. It has a simple shape with a greenery roof, and is incorporated into the existing spaces of the square. The distinctive element of the design is an open outside atrium in the first underground level. The facase is covered with boards (nebo „panels“) made out of Corian® material in a white shade of Glacier White in contrast to glass windows. The supporting construction is designed from monolithic iron concrete.
