A presente pesquisa tem como objetivo desenvolver um novo elemento de cobertura, compatível com o meio ambiente: telhas de cimento alternativo reforçado com fibras celulósicas. Para tanto, foram utilizadas matérias-primas consideradas resíduos industriais (cimento de escória de alto-forno e rejeito de polpa de celulose de eucalipto) para obtenção de pastas cimentícias reforçadas. Os compósitos foram produzidos por dispersão prévia das fibras em água, mistura do compósito em argamassadeira convencional, adensamento por vibração, moldagem em fôrmas, seguida de cura úmida. Foram moldadas placas planas de diferentes formulações de matrizes cimentícias, com as matérias-primas alternativas disponíveis. Com base nos melhores resultados dessa fase preliminar, foram produzidas duas séries de telhas tipo romana \"capa canal\". Foram avaliados o desempenho físico-mecânico, os custos de produção e o comportamento térmico das telhas. Os resultados revelaram a potencialidade dos compósitos obtidos na produção de fibrocimentos alternativos, por meio de técnicas simples e de baixo consumo de energia, direcionados à autoconstrução urbana e rural de baixo custo. / The objective of this study was to develop a new roofing material that would be compatible with the environment: roofing tiles made of alternative cement reinforced with cellulose fibers. Industrial waste materials were used as raw materials (blast furnace slag cement and waste eucalyptus cellulose pulp) to obtain reinforced cement pastes. The composites were produced by previously dispersing the fibers in water, mixing the composite in a conventional cement-mixer, compaction by vibration, shaping them in molds, followed by moist curing. Flat sheets were molded using different formulations of cement matrixes with the alternative raw materials avaiable. Based on the best results from this preliminary phase, two series of Roman tiles for roofing were produced. The physical and mechanical performance, the cost of production, and the thermal behavior of the tiles were evaluated. The results revealed the potential of composites made of alternative fiber-cements, using simple techniques and with low energy consumption, in urban and rural areas for low-cost self-construction.

The master’s thesis deals with new building of hotel in Bludov. The thesis is processed in the form of project documentation for new building, containing all the requirements according to applicable standards and regulations. The building is located on flat terrain. Two-floor, partially basement building respects the height of existing buildings. In the basement there is a technical background. At the ground floor is located restaurant with kitchen facilities, fitness centre, infrared sauna, relaxation room and wheelchair access rooms. On the second floor there are rooms for the guests. Peripheral masonry of the basement is composed of permanent formwork. The remaining walls are made up of brick blocks. The roof over part of the ground floor contains vegetation. Roof above the second deck is partially saddle roof and mono-pitched roof.

The main objective of the thesis is to introduce the prices of construction industry and methods of their determination. Furthermore I will introduce selected historical monument - the former provincial hospital in Prague, well known today as „Porodnice u Apolináře“ and I will focus on its history and current status. The budget for the reconstruction of the roof covering of cultural heritage will be set up a in accordance with the requirements of the „Národní památkový ústav“ (slate roofing) based on available inputs. Then the prices of different types of roofing will be compared and evaluated with regard to their lifetime.

Three studies were conducted to better understand the current status of the industry and create a design process and taxonomy. Study 1 assessed current industry usage of dust control technologies and stakeholder perceptions in the concrete and masonry trades. Study 2 was similar but assessed emission control technologies in the asphalt roofing trade. Study 3 used the information from studies 1 and 2 to select a tool for further evaluation. The handheld cutoff concrete saw was chosen. An iterative design process was utilized to evaluate the saw. The design process and subsequent usability inspection engendered a taxonomy, or set of design recommendations can be applied to large handheld powered tools. / Ph. D.

A linear analysis of a commercial aluminum lattice dome was performed with the loads prescribed by the American National Standards Institute. The pressure snow loads were transformed into a distributed load along the dome members. The analysis of the dome was performed with the structural analysis program STAAD-III. The dome was modeled as a space frame with the joint member stiffness range from pinned-end to four times the member stiffness. The internal forces in the pinned-end and framed-end models were compared to the specifications by the Aluminum Association. The pinned-end model under the unbalanced snow load were found to exceed the allowable. The maximum deflection occurred when the joint stiffness was one-half of the member stiffness. The maximum axial force occurred when the joint stiffness was four times the member stiffness. The maximum moment at the midpoint of the member occurs when the member ends are pinned. / Master of Science

There is a body of evidence indicating that the implementation of current Architecture, Engineering, and Construction (AEC) industry business models and practices have caused negative impacts on global energy supply, ecosystems, and local or regional economies. In order to eliminate such negative impacts, AEC practitioners are seeking new business models in which the Building Information Modeling (BIM) technology can be considered an important technology driver. Despite the fact that the majority of AEC practitioners have used BIM tools for construction-level modeling purposes, some early adopters of BIM technology began to use BIM tools to better inform their design decisions. Corresponding to the increasing demand for decision support functionality, a number of studies showed that a part of BIM technology will be developed toward decision support and artificial intelligence domains. The use of computer-based systems to support decision making processes can usually be found in the business management field. In this field, decision support and business intelligence systems are widely used for improving the quality of managerial decisions. Because of its theories and principles, Decision Support Systems (DSS) can be considered as one of the potential information technologies that can be applied to enhance the quality of design decisions. The DSS also has the potential to be constructed as a system platform for implementing building information contained in BIM models associated with other databases, analytical models, and expert knowledge used by AEC practitioners. This study explores an opportunity to extend the capability of BIM technology toward the decision support and artificial intelligence domains by applying the theories and principles of DSS. This research comprises the development of a prototype BIM interoperable web-based DSS for vegetated roofing system selection. The prototype development can be considered a part of an ongoing research agenda focusing on the development of the integrated web-based DSS for holistic building design conducted within the College of Architecture and Urban Studies (CAUS), Virginia Tech. Through a post-use interview study, the developed prototype is used as a tool for evaluating the possibility for the DSS development and the usefulness of DSS in improving the quality of vegetated roofing system design decisions. The understanding gained from the post-use study is used to create a guideline for developing a fully functional DSS for holistic building design that will be developed in the future. / Ph. D.
