Favorit Brno / cyklistický stadion - bikrosová dráha / architektonická studie - design / druhá etapa / Favorit Brno / cycling stadium - bicross track / architectural study - design / second stage

Slunečková, Magdaléna January 2021 (has links)
The topic of this diploma thesis is the architectural study of the cycling arena – velodrome – as a part of The Hněvkovský sports ground in Brno-Komárov. The new velodrome is situated next to the existing bicycle motocross ground and serves as a facility for the track cycling, indoor cycling and BMX. The core of the velodrome consists of the 250-meter wooden steeply banked track, which, together with other sports ground’s parameters fits the requirements of International Cyling Uninon for hosting international competitions. Cycling arena includes premises for athletes, spectators (stands are designed for 2700 spectators) and Favorit Brno administration and also bicycle storage and service areas. Facility includes also gym, fitness room, wellness and physiotherapy, athletes‘ accomodation. The velodrome is roofed with the arch-formed membrane anchored to a robust bond beam, that is brought to the ground in the front part of the building. This V-shaped bond beam together with the arched membrane geometry defines the building dynamic expression.

Vývoj střešních konstrukcí od antiky po 20. století / The Development of the Roof Structures from Antiquity to the 20th Century

Urych, Jan January 2018 (has links)
This diploma thesis deals with the historical development of roof structures and materials used in their construction. The development in time can be delimited from the antique Rome and Greek up to the introduction of modern reinforced concrete structures in the twentieth century. The paper focuses not only on the roof structures and their types, but also on the appropriate roofing. In addition, it highlights the advantages or disadvantages of the individual types of structures, their elements and other relevant things. It is also devoted to the typology of the materials, their development and correct processing. The main aim of this work is to summarize the information and to outline the development from the earliest times up to the present.

Measuring the Effect of Vegetated Roofs on the Performance of Photovoltaic Panels in Combined Systems

Ogaili, Hamid Hawi Kadham 05 May 2015 (has links)
Recent studies suggest that integration of photovoltaic panels with green roofs may improve the performance of both. While vegetation may provide a benefit by reducing the net radiation load on the underside of the photovoltaic (PV) panels, it may also affect convective cooling of panels, and consequently, panel efficiency. Both effects likely diminish with the height of the PV panel above the roof, although placing PV panels too close to the vegetation increases the risk of the plants growing over the edges of, and shading the PV panel. There is a gap in the literature with respect to evaluating these competing effects. The present study aims to fill this gap. Experiments were conducted over a two-month period during summer using two identical PV panels within an array of rooftop-mounted panels. These experiments were performed at two heights (18 cm and 24 cm) using three roofing types: white, black and green (vegetated). Results showed that the mean power output of the system in which the PV panel was mounted above a green roof was 1.2% and 0.8% higher than that of the PV-black roof and the PV-white roof at the 18 cm height. At the 24 cm height, the benefit of the green roof was slightly diminished with power output for the PV panel above a green roof being 1.0% and 0.7% higher than the black and white roof experiments, respectively. These power output results were consistent with measured variations in mean panel surface temperatures; the green roof systems were generally cooler by 1.5˚C to 3˚C. The panel surface mean heat transfer coefficients for the PV-green roof were generally 10 to 23% higher than for the white and black roof configurations, suggesting a mixing benefit associated with the roughness of the plant canopy. As expected, the results indicate that the best PV panel performance is obtained by locating the PV panel above a green roof. However, the relative benefits of the roof energy balance diminish with distance between the PV panel and the roof. Moreover, the results of this study showed that the mean power output of the PV panel above the white roof was 0.7% and 0.44% higher than that of the PV panel above the black roof at 18 cm and 24 cm heights, respectively. The results of the power output differences in all the experiments were statistically significant at the 95% confidence interval (P < 0.01).

Karaktärisering av stålplåt : Metallografi och kemisk analys / Characterization of steel sheet : Metallography and chemical analysis

Petersson, Rickard, Nilsson, Rebecca January 2017 (has links)
Studien har genomförts på ett antal stålplåtar från olika kulturhistoriska byggnader. När kulturhistoriskt värdefulla byggnader ska renoveras måste detta göras med så god kunskap som möjligt om byggnadens olika delar och de värden dessa representerar. Det problem som studien har ämnat att lösa har varit en bristande kunskap om historiska stålplåtar. Studien har därför utförts för att bidra med kunskap som kan användas när gamla byggnader ska renoveras.För att uppnå syftet att bidra med kunskap som kan vägleda renovering av kulturhistoriska byggnader har studiens mål varit att undersöka hur de olika plåtarna tillverkats och vilka resultat de processerna har fått.Detta har genomförts genom att utföra en metallografi på samtliga prover för att undersöka deras mikrostrukturer och få en förståelse för materialen. Även en kemisk analys av materialens innehåll har gjorts genom en optisk emissions spektroskopi.De resultat som hämtades från plåtarna visade hur stor skillnad det var mellan olika tillverkningsmetoder och deras konsekvenser. Genom att ha sett den mångfald av egenskaper som fanns bland plåtarna har slutsatserna dragits att det finns ett värde i att respektera de äldre materialen.Genom att vara medveten om att det kan finnas stora skillnader i materialen kan valet av plåt göras på ett bättre sätt. Under studiens gång blev det även uppenbart hur mycket historia som fanns lagrad i de gamla plåtarna som är viktig att ta vara på. / The study has been conducted on a number of steel plates from different buildings of cultural and historical value. When old, cultural buildings are to be renovated, it must be done with as much knowledge as possible about the different parts of the building and the values that they represent. The problem that the study has aimed to solve has been an inadequate level of knowledge in regards to historical steel plates. Because of this, the study has been conducted to contribute with knowledge that could be used when old buildings are to be renovated.To achieve the purpose of contributing knowledge to guide renovations of culturally and historically valuable buildings, the goal of the study has been to analyze how the different plates have been made and what the results of those processes were.This has been carried out by conducting a metallography on all of the samples to analyze their microstructures and to gain an understanding of the materials. A chemical analysis has also been conducted on the contents of the materials by using optical emission spectroscopy.The results showed how big of a difference there was between different manufacturing methods and their consequences. By discovering the diversity of the properties of the plates the conclusion has been drawn that there is value in respecting the values of the older materials.By being conscious of how large the difference is between different types of steel sheets, better decisions can be made during choice of steel sheet, and it is more obvious how much history that is stored within the old plates.
