Roof venting is often utilised in large warehouses to remove smoke in order to reduce damage to a building and its contents, and to maintain access for fire-fighters. In New Zealand, the Compliance Document for the New Zealand Building Code C clauses recommends 15 % opening area for unsprinklered single floor buildings. This opening area is required to be designed for effective fire venting. There is no justification for why 15 % is required, and no definition of how fire venting qualifies as being effective. Fire Dynamics Simulator (FDS) was used to simulate the performance of various roof venting strategies in two different-sized industrial warehouses (both larger than 1,500 m²) with a 50 MW fire with both a rapid and an extreme t³ growth rate. In particular, roof venting areas of 15 %, 10 %, and 5 % of the floor area were tested with each of the following inlet areas for make-up air: 100 %, 50 %, and 0 % of roof venting area. In each of these cases, the vents were treated as permanently-open holes in the roof. It was shown that roof venting with 15 % geometric area is ample to provide and maintain tenability for fire-fighters. With sufficient inlet area for make-up air, smaller venting areas could also be employed. Further simulations were run to test the effect of square-shaped vents that opened simultaneously at 100°C compared with square-shaped vents that opened sequentially at 100°C, 200°C, and 300°C, and strip-shaped vents that opened progressively as each portion of a vent reached activation temperatures of 200°C and 300°C. Vents that opened at 100°C were intended to represent mechanical vents, while vents opening at higher temperatures were intended to represent plastic sky-light or drop-out type vents. The activation temperature proved to be more influential than the opening sequence or shape: there was a significant advantage to be gained by having vents that activated at 100°C as opposed to 200°C or 300°C. The role of downstands in aiding the effectiveness of roof venting was also investigated, with downstand depths of 10 %, 20 %, and 30 % of the ceiling height being simulated. Downstands were shown to be incredibly useful for exhausting smoke and hot gases, provided their installation was appropriately coordinated with placement of roof venting. It is concluded that a clear definition of effective fire venting must not only include the area of roof venting, but equally important is the definition of required inlet area for make-up air, as it plays a crucial role in the effectiveness of the specified roof venting area. In addition, the clear aerodynamic area should be specified. This could be achieved by use of a discharge coefficient that describes the proportion of the roof venting area that is clear aerodynamic area for a particular material, vent, and geometric area. Development of a clear definition of effective fire venting will help to determine how an economic fire protection system can be continued to be used, while going a long way to ensuring predictable and tenable conditions for fire-fighters in New Zealand.

In North America, the operation of buildings accounts for approximately one third of the total energy use and greenhouse gas emissions annually. Office buildings are responsible for roughly 35% of the total commercial/institutional secondary energy use in Canada, followed by retail buildings at 17% (NRCan, OEE, 2010). In recent years, a number of researchers from around the world have conducted life-cycle assessment (LCA) studies to investigate the impacts of buildings on the environment. Most studies have focused on three types of buildings: office buildings, single residential dwellings, and multi-unit residential apartments. There have been almost no comprehensive LCA studies of retail buildings, specifically single-storey retail buildings. This is a problem, since compared to office buildings, single residential dwellings, and multi-unit residential apartments, retail buildings consume approximately 1.2, 2.0, and 2.3 times more energy per floor area respectively (NRCan, OEE, 2010). In addition, retail buildings usually undergo major resource intensive renovations far sooner than other building types. Therefore, the primary goal of this study was to conduct a comprehensive LCA for the components of a single-storey retail building located in Toronto, Canada, to determine which building components contribute the most towards the total life-cycle energy use and global warming potential (GWP) after 50 years. Using the latest LCA techniques, the total life-cycle energy use and GWP was calculated for 220 different building components including: exterior infill walls, roofs, structural systems, floors, windows, doors, foundations, and interior partition walls. Also, a comprehensive LCA study was conducted for five single-storey retail buildings (including a pre-engineered steel building system which is lacking in the literature), in order to determine which components of a single-storey retail building are responsible for the most environmental damage. For a typical single-storey retail building located in Toronto, Canada, the operating energy (and GWP) accounts for about 91% (88%) and the total embodied energy (and GWP) accounts for about 9% (12%) of the total energy (and GWP) after 50 years. The roof alone is responsible for nearly half of the total embodied energy and GWP of the entire building. The LCA study also found that after 50 years, the total energy (and GWP) of the five case study buildings only differed at most by 6% (7%), regardless of the choice of structural system, or whether the building was made predominately of steel or wood building components. This thesis concludes with a prioritized list of recommendations for reducing the total life-cycle energy use and GWP of a single-storey retail building in Canada.

The topic of my diploma project is a design and a project documentation of a kindergarten in the city of Ružomberok. The building is located on a flat land with a rectangular shape in a peaceful locality. The floor plan of the building is atypical.The building consists of a ground floor with a partial basement. The structural wooden system uses massive wooden wall panels by Novatop. The basement is made of a concrete structural system. The structure is based on the concrete strip foundations and it has a flat roof. The kindergarten is divided into the class sections and a utility part with a kitchen. Overall, there are three classes with the maximum capacity of 60 children. Two class sections are of the same hight and the one in the middle is raised. All the day rooms are south-facing and each of them has a direct access to the wooden terrace. On the east side of the site there is a parking lot designed for 16 cars with a path leading to the main gate and to the building entrances. The entrances to the kindergarten and to the utility part are separated. The main entrance to the kindergarten is designed as barrier-free.

The point of my diploma thesis was design elements of reinforced concrete frame structures mounted single – storey mall.I choose the most exposed to the specified longitudinal frame structure, where I assumed the most highly stressed elements, which I subsequently designed. All documents and calculations are illustrated in part B2 of my diploma thesis.

The object is designed as a standalone barrier-free single-storey building. Kindergarten consists of two departments with a capacity of 48 pupils and adjacent facilities. The object is based on foundation pads and ground table. All masonry constructions are lime-sand blocks Kalksandstein. The facade is complemented by thermal isolation and the exterior staircase is monolithic and reinforced concrete. The object has a flat roof where an air conditioning unit is placed. The drawing is processed via AutoCAD software and visuals are created in program Sketchup.

[pt] Os sistemas de cobertura constituem uma parcela considerável dos custos finais de galpões de grandes dimensões. Os carregamentos desse sistema são transferidos para os pilares a partir dos vigamentos principais. Dúvidas sobre qual é a melhor solução para o dimensionamento do vigamento principal podem surgir devido aos grandes vãos que essas estruturas devem cumprir. Esta dissertação apresenta um estudo das configurações estruturais e uso de diferentes materiais para o projeto, fabricação e montagem de coberturas de galpões de grandes dimensões. Foram desenvolvidos diversos projetos de uma estrutura modelo onde se variou o tipo de perfil das cordas, o comprimento dos vãos, a geometria da seção transversal da treliça e a inclinação das diagonais. A partir dos resultados obtidos, realizou-se uma análise paramétrica buscando-se a solução que apresenta o menor peso estrutural dos vigamentos principais. A grande vantagem da utilização de treliças multiplanares é o bom comportamento fora do plano que esse tipo de estrutura oferece, podendo reduzir custos com travamentos e elementos secundários. Também foi realizado um estudo determinístico para dar apoio às decisões na escolha da melhor solução para os diversos tipos de galpões de grandes dimensões estudados. Os resultados preliminares obtidos indicam que a solução de cordas tubulares mistas, em partes selecionadas da estrutura, representa uma das soluções mais competitivas para este tipo de estrutura. / [en] Roofing systems constitute a considerable part of the final costs of large single-storey buildings. The loads of this system are transferred to the columns from the girders. During the design process may be raised the question of what may be the best solutions for the roof supporting girders, mainly due to the large spans required. This dissertation presents a study of the structural configurations and the use of different materials for the design, manufacture and assembly of roofs of large single-storey buildings. Several designs of a model structure were developed where the type of profile of the main chords, the length of the spans, the geometry of the cross-section of the truss and the angulation of diagonals were varied. Based on the obtained results, a parametric analysis was performed focused on solutions presenting the lower structural weight of the girders. The great advantage of using multiplanar trusses is the good behavior out of plane that this type of structure offers, which can reduce costs with bracing and secondary elements. A deterministic study was also carried out in order to support decisions in choosing the best solution for the various types of large single-storey buildings studied. The preliminary results obtained indicate that the solution of concrete filled steel tubular chords in selected parts of the structure represents one of the most competitive solutions for this type of construction.
