ABSTRACT OUT OF THE GREYZONE: EXPLORING GREYFIELD DESIGN AND REDEVELOPMENT Konstantinos Pavlou Advisor: University of Guelph, 2013 Professor Cecelia Paine Community shopping centres in many North American suburban areas have been in decline for two decades. Failed community shopping centres, termed ‘greyfields’, have resulted in large parcels of unused lands in core urban areas, forcing residents to travel longer distances to regional malls. The decline of community shopping centres may have a number of causes, but for this study it was hypothesized that successful community shopping centres share a number of design qualities that unsuccessful shopping centres do not have. A design framework was developed based on retail design and planning literature. The framework was applied to assess an existing redevelopment, the Shops at Don Mills in Toronto. The assessment findings derived from site observations and key informant interviews resulted in a revised design framework. The final framework provides a guide to those interested in transforming commercial greyfields into vibrant components of our urban communities.

This project will address the environmental and social issues associated with conventional community planning and propose solutions to these through written documentation as well as through masterplan-scale concepts of a proposed mixed-use project using principles derived from the New Urbanist movement. The site chosen to display these conceptualizations is that of the existing Delaware County Fairgrounds located in Muncie, Indiana. Two concepts for a traditional neighborhood development shall be the graphic product of the project. The concepts shall be used in a comparison of the potential for New Urbanist design principles applied within the confines of existing zoning and development regulation and New Urbanist-derived design principles applied in an unrestricted setting. The concepts will be used to illustrate the potential of the site as a primarily residential space. / Department of Landscape Architecture

Over 90% of the land area of Turkey lies over one of the most active seismic zones in the world. Hazardous earthquakes frequently occur and cause heavy damage to the economy of the country as well as human lives. Unfortunately, the majority of buildings in Turkey do not have enough seismic resistance capacity. The most commonly observed problems are faulty system configuration, insufficient lateral stiffness, improper detailing, poor material quality and mistakes during construction. Strengthening of R/C framed structures by using cast-in-place R/C infills leads to a huge construction work and is time consuming. On the other hand, using prefabricated panel infills can be preferred as a more feasible, rapid and easy technique during which the structure can remain operational. The aim of this experimental study is to observe the seismic behavior of R/C frames strengthened by precast concrete panel infills by testing different types of panel and connection designs in eight single-story single-bay reinforced concrete frame specimens.

The construction of reinforced concrete buildings with unreinforced infill is common practice even in seismically active country such as Bhutan, which is located in high seismic region of Eastern Himalaya. All buildings constructed prior 1998 were constructed without seismic provisions while those constructed after this period adopted seismic codes of neighbouring country, India. However, the codes have limited information on the design of infilled structures besides having differences in architectural requirements which may compound the structural problems. Although the influence of infill on the reinforced concrete framed structures is known, the present seismic codes do not consider it due to the lack of sufficient information. Time history analyses were performed to study the influence of infill on the performance of concrete framed structures. Important parameters were considered and the results presented in a manner that can be used by practitioners. The results show that the influence of infill on the structural performance is significant. The structural responses such as fundamental period, roof displacement, inter-storey drift ratio, stresses in infill wall and structural member forces of beams and column generally reduce, with incorporation of infill wall. The structures designed and constructed with or without seismic provision perform in a similar manner if the infills of high strength are used.

The archaeobotanical analysis of the waste infill contributed to understanding its origin and composition based of two types of sample extraction. Large amount of desiccated botanical marco-remains was determinated. Beside of the common taxa rare imported species were also captured. Some of them are the first determinations in Central Europe; one case is the first evidence in Europe at all. The richness and uniqueness of the archaeobotanical collection declare the high society status, economical and cultural centre of the Prague castle in the early modern period.

No presente trabalho trata-se de um estudo da contribuição de painéis pré-moldados de fechamento no enrijecimento da estrutura principal, com relação às ações laterais. Inicialmente são apontados os critérios correntes de dimensionamento dos painéis pré-moldados de fechamento sem a consideração da interação destes com a estrutura principal. Em seguida, são desenvolvidas simulações numéricas em três exemplos com o objetivo de avaliar tal efeito. Estes exemplos englobam as seguintes situações: painel isolado, estrutura de um pavimento e uma estrutura de vários pavimentos. Os principias parâmetros analisados são os deslocamentos na estrutura principal, os esforços nas ligações e as tensões nos painéis. Os resultados obtidos mostram a importância da contribuição dos painéis no enrijecimento da estrutura principal. Na estrutura de um único pavimento analisada, a consideração de interação possibilita a passagem de situação em que os efeitos globais de segunda ordem são relevantes para aquela em que tais efeitos são desprezíveis. Para a estrutura analisada de vários pavimentos, a consideração de interação resulta em significativas economias de materiais apontando para economia da ordem de 20% na estrutura principal. Com base nos resultados, conclui-se que os painéis de fechamento pode ser incorporados numa estratégia de projeto, possibilitando economia na estrutura principal. / This work presents a study of the precast panels contribution in the main frame stiffness, subjected to lateral loads. At first, currents criteria of panels design are analyzed, without considering the interaction with the main frame. After that, three examples are calculated using numerical simulation to evaluate this effect. These examples include the following situations: a single panel, an one-story frame and a multi-story frame. The parameters are: the frame displacements, the connections efforts and the panels tensions. The results show the magnitude of the panels contribution. In fact, to the one-story frame, it was possible to pass from a flexible structure where the second-order effects must be taken into account to an other one where this effects could be neglected. For the multi-story frame analysis, the panels contribution produced an effective material economy of about 20% (and consequent cost reduction). Basing on these results, one can conclude that the infill panels can be included in the design strategy with economy for the structural system.

This study focuses on non-ductile reinforced concrete (RC) frames built outside current practices. These structures are quite vulnerable to collapse during earthquakes. One option to retrofit buildings with poorly detailed RC columns is to construct full-height masonry infill walls to provide additional means to resist loads caused by gravity and increase lateral stiffness resulting in a reduction in drift demand. On the other hand, infill can cause reductions in drift capacity that offset the benefits of reductions in drift demand. Given these two opposing effects, this investigation addresses the following question: are poorly detailed RC frames with masonry infill walls any safer than similar RC frames without infill walls?

Diplom thesis is about design of an office building. Building floor plan is designed as a rectangle. The building consists of four floors. Roofing the object is solved by a flat roof with strips of m-PVC. The purpose of the internal arrangement is to be able to lease office space to individual firms on the floor. On the first floor is situated an entrance hall with space for the doorman and staircase area. At the hall is also a personal elevator and utility room. These spaces are common to all tenants. In the space for offices are located toilets for women, for men and one toilet for the disabled. Kitchen with lounge and six offices. These spaces are connected with single corridor. The other floors are connected to administrative with hall, which houses a staircase and an elevator. In office spaces 2.NP. 3.NP and 4.NP are located toilets for women, for men and one toilet for the disabled. Kitchen with lounge, utility room and nine offices. These spaces are connected with single corridor. From these levels, there is also access to the evacuation staircase, which is designed according to the requirements for fire protection. On the 4.NP in the utility room is located auditing roof ascent. The project was developed in the educational version of ArchiCAD 17 and processed in accordance with the requirements of a layout, architectural design, structural design, proper and safe use of the building.
