  • There are 5 kinds of architectural fabrics in our country recently. The test piece were made by attaching on the steel disk which has been tested of various range of the test conditions in pin-on-disk wear testing machine. The results show that the friction coefficient and wear rate of the architectural fabrics are heavily dependent on the load and materials. PVDF type was better than others in wear rate and friction coefficient.

  • Architectural fabrics are now used in membrane structure with the merits of free shape, lightness and opened up new possibility for the design of new building structures. Recently PVC, PVF, PVDF, PTFE coated fabric for using the membrane structures. However, clear standards for the design and construction is not exist because of the lack of Architectural fabric research. In this paper, Flammable properties of PVDF, PTFE coated fabrics are obtained through the Flammability test using the Cone Calorimeter. Based on these results, identify the fire resistance property of the Architectural fabric.

  • Acoustic performances of the steel-wire fabrics manufactured from the crushed tires were experimentally investigated for various thicknesses and bulk densities. The well- known two-cavity method was used to measure the characteristic impedances, the propagation constants, and the absorption coefficients. The normal absorption coefficients measured by the two-cavity method agreed well with those measured by the two-microphone impedance tube method. The experimental results showed that the magnitude and frequency range of the absorption coefficient were controllable by changing the thickness and the bulk density of the steel-wire fabrics. Therefore, the steel-wire fabrics from the crushed tires can be successfully used as a good sound absorbing material.

  • The membrane structure is being applied in structures for various uses for its many advantages as permeableness, lightweightness, constructability, resource saving, and management cost reduction, and the usage is being expanded. However, despite the development of membrane structure, the standard for architectural membrane performance that considered fire safety is still inadequate. Therefore, this study applied basalt fiber with flame resistance on architectural membrane. Also, this study confirmed the membrane applicability of basalt fiber through comparison with existing architectural membrane.

  • Membrane structures which can be used large spatial structure are being expanded because of various advantages. However, despite the diverse membrane structure buildings and materials, the standard for membrane material performance that considering fire safety is still inadequate. Therefore, this study applied basalt or glass woven fabric with flame resistance on architectural membrane, and report the fire safety for architectural membrane using the strength properties, flammability and incombustibility. From the test result, the architectural membrane using basalt or glass woven fabric showed a low heat release rate and total heat release. Therefore, it was confirmed that the fire safety is relatively high.

  • The purpose of this study is to apply the Trencadis images in Antony Gaudi's work to a design motive and thus provide a new concept for a knitwear design by combining double-knitted fabrics with patchwork applique, taping, stitching and quilting. This study examines the bibliographic text and precedent research related to Antony Gaudi and his works, and analyzes the historical background and formative and stylistic characteristics of Trencadis as it appeared in Gaudi's architectural works. Also this study also examines the characteristics of knitwear and knitting theory while exploring the formative elements and the combined techniques used in modern knitwear design through fashion magazines, medium images, and online sources. The results are as follows: First, Gaudi's work that applies a Trencadis technique has the characteristic of being creative, organic, and environmentally friendly. And in addition, its colorfulness inspires modern fashion design. Second, computerized knitting has been practiced in various ways and the fabrics knitted by both double-knitting jacquard and computerized knitting machines provide a new direction the creation of knitwear. A computerized knitting machine is especially effective for pictorial expression, and is suitable for showing the natural curve of the human body due to its sophistication. Third, as a result of applying a combined technique to the knitting of various fabrics, a combined or fusion design, which is a recent megatrend, is very effective for the design of knitwear while increasing its aesthetic value. Moreover, utilizing techniques that combine patchwork applique, taping, stitching and quilting will create higher value in knitwear. Lastly, with a project of applying combined techniques in the creation of knitwear, designers can become much more creative while taking their imagination much further.

  • The threads of this thesis are several theoretical issues of modern urban ideals. Modern architects and urban designers conceived their individual artifacts, which assumed to be laid out on the new settings totally different from the existing urban fabrics derived from inherently medieval ones. In the discussion of modern ideal society, the Industrial Revolution and the Enlightenment was a pivotal point. Innovations in technology and expanded living territories since the double revolution have been critical factors in the evolution of new ideas of urbanism. The tremendous success in science and technology led a way to the 'science-fiction' environment as a destined apocalyptic world. The dream, whether it was socialist or in any other believes, to a pastoral utopia beyond the capitalist society was represented through the ideal cities, which were modern versions of arcadia in the other approaches. Two sides of revolutionary ideas are presented as a futurist city and a garden city, which are on the separate notions but co-existed or overlapped in a single urban project such as in Le Corbusier urban schemes or even Tchumi's recent work, Parc de la Villette. Urban ideas in the twentieth century are based on urban naturalism, the notion of which was consistant from abbe Laugier to Le Corbusier, as well as machine aesthetics interpreted in terms of archeological research and modern technology.

  • Architectural fabrics membranes have not only the structural performance but also act as an efficient cladding to cover large areas. Because of the direct relationship between form and force distribution in tension membrane structures, form-finding procedure is an important issue. Ideally, once the optimal form is found, a uniform pre-stressing is applied to the fabric which takes the form of a minimal surface. The force density method is one of the most efficient computational form-finding techniques to solve the initial equilibrium equations. In this method, the force density ratios of the borders to the membrane is the main parameter for shape-finding. In fact, the shape is evolved and improved with the help of the stress state that is combined with the desired boundary conditions. This paper is evaluated the optimum amount of this ratio considering the curvature of the flexible boarders for structural configurations, i.e., hypar and conic membranes. Results of this study can be used (in the absence of the guidelines) for the fast and optimal design of fabric structures.
