Extensive research to determine the strength of steel deck reinforced concrete floor systems has been carried out on single-span, single panel width test specimens. Little of this research has considered the benefits that actual field conditions have on overall strength and stiffness. This experimental study investigates typical field details at intermediate supports and end spans. In particular, the influence of adjacent spans and typical pour stop details are considered. Additionally, this study illustrates the applicability of simple analytical models, which can be used to determine the strength and stiffness of steel deck reinforced concrete floor systems. / Master of Science

The Engineering Index was the primary reference for the articles listed in this bibliography. There are a few articles included which have been taken from various engineering experiment station bulletins. In order to determine the extent of coverage of the Engineering Index, several of the articles which appeared as experiment station bulletins were cross-checked and found listed in the Index. While it is possible that some significant articles may have been omitted from the Index, it is hoped that they were of less importance than any of those which have been listed. The first volume of the Engineering Index appeared in 1884, therefore this bibliography will be limited to those articles listed in the issues of 1884 to May 1951 inclusive. All of the articles published in the United States, Canada, and England, and which were found to be on the campus, were read in a cursory manner in order to determine their applicability to the problem. In each case where the article was read, written additions were made to the abstracts in order that they might be more helpful to anyone using the bibliography. The part of the abstract enclosed with quotation marks was taken from the Index, the rest of the information was added. Photographic copies and English translations of all of the articles listed may be obtained from the publishers of the Engineering Index. It is hoped that this compilation of works on the integral action of beams, columns and slabs will prove helpful to anyone interested in this subject. / Master of Science

Laminate flooring manufacturers have received negative feedback from customers on the sound quality of laminate flooring installations. Customers express a preference for the sound of traditional hardwood floors over that of laminate flooring composites. Consumers notice a difference between the sounds created by a footfall between laminate flooring and hardwood flooring. They perceive the laminate flooring sound of a footfall to be annoying and associate it to the flooring being of a lower quality. No objective test procedure exists to validate the marketing claims of the performance of these products. The objective of the work in this thesis is to develop a test method that evaluates the human perception of the sound quality of footfall noise on laminate flooring composites.

Esta dissertação apresenta um estudo sobre os revestimentos em granilite levando-se em consideração as características do material, de seus materiais constituintes e os processos de produção e execução desse revestimento. Ressalta patologias recorrentes nesse tipo de revestimento, em especial fissurações e desplacamentos. Para estudar a problemática da fissuração e encontrar uma alternativa para que não ocorra, foram produzidos três modelos em granilite com características distintas, que visaram avaliar o comportamento de granilites com e sem solidarização. Para o estudo do sistema solidarizado foram executados: um quadro de 16 \'M POT.2\' e quatro quadros de 2,25 \'M POT.2\' moldados sobre argamassa comumente utilizada como regularização de revestimentos. Para a dessolidarização foi utilizada argamassa mista de cimento e cal com baixo módulo de elasticidade e baixa resistência mecânica, servindo como camada de regularização. Os quadros solidarizados apresentaram fissuras de maneira generalizada e demonstraram que os granilites em sistemas solidarizados fissuram com a fissuração do material a ele monolitizado. Para o quadro dessolidarizado, de 16 \'M POT.2\', o sistema se mostrou eficaz para a não ocorrência de fissuras, apresentando resultados positivos. / This dissertation presents the terrazzo flooring considering the characteristics of the material, constituent materials and the process of production and execution of this covering. Emphasize the recurring pathologies of this type of covering, especially cracking and caused by deficient adherence at the interface zone. To study the problem of cracking and find an alternative that does not occur, it was produced three models in terrazzo with distinct characteristics, that aimed to evaluate the behavior of solidarized and dessolidarized terrazzo. For the study of this monolithic system it was executed: a board of 16 \'M POT.2\' and four boards of 2,25 \'M POT.2\' casted over a mortar commonly used as covering regularization. These boards presented cracks in a generalized way and showed that terrazzo in the monolithic systems open cracks with the material that is monolithically attached to them. For the non-monolithic board, of 16 \'M POT.2\', the system was effective for the absence of cracks, showing positive results. For the non-monolithic system it was used a mixed mortar of cement and lime with low elasticity modulus and low mechanical resistance, serving as a layer of regulation.

The key issue addressed by this dissertation is that a number of heritage buildings undergoing the adaptive reuse are having building components such as timber structure, timber staircase which cannot meet the current fire safety regulation. Given this, it is imperative to begin researching the reasons why the timber component in heritage buildings cannot comply with the current statutory fire resistance requirement and find out the methods in preserving the timber component. The dissertation will focus on timber floor which is a highly important component in meeting the fire safety requirement as it provides the compartment separation to inhabit the rapid spread of fire and smoke in a building and as the same time it is usually a character defining element having heritage value. The dissertation will try to find out the different methods of conserving the timber floor of the heritage building under adaptive reuse with examples. The different methods will be evaluated based on the fire performance, statutory acceptance and conservation principles and the appropriate method will be matched to the adaptive reuse heritage buildings in Hong Kong. / published_or_final_version / Conservation / Master / Master of Science in Conservation

A nation-wide survey of hardwood flooring manufacturers was conducted in the spring of 1998. The objectives of the study were to determine the differences in beliefs towards certification between certified and non-certified hardwood flooring manufacturers and to explore the decision to certify and the implications of that decision. Those objectives were chosen because certification is a developing phenomenon of which there are some aspects that remain unknown. The survey consisted of a mail questionnaire that was sent to more than 250 hardwood flooring manufacturers. The questionnaire was used to collect demographic and attitudinal information from the respondents about certification. The second part of the research used the Analytic Hierarchy Process to model the decision process hardwood flooring manufacturers go through when deciding whether or not to certify. Data were collected as part of the mail questionnaire. The final goal of the research, to explore the experiences of certified manufacturers, was met through the use of personal interviews with the manufacturers. The results from the mail survey indicated that certified hardwood flooring manufacturers tended to be smaller than non-certified hardwood flooring manufacturers. The total amount of certified hardwood flooring produced in the U.S. in 1997 was estimated to be 435,579 bdft, roughly 0.1% of the total reported amount of hardwood flooring produced. The research also indicated that certified manufacturers felt that there was a need for certification in the U.S. and that it was the environmentally responsible thing to do, while the non-certified manufacturers felt that that was untrue. The most important factor in the non-certified manufacturers' decision whether to certify is the profit potential of the product, while the certified manufacturers based their decision to certify on the marketing advantages, image benefits, and access to new markets that the certified product provides. Overall, certified and non-certified hardwood flooring manufacturers hold widely differing views on certification, and those differing beliefs contribute to the choices each group makes. / Ph. D.
