The multilateral attempt for present applications of art school of thought and expression is leading modern fashion as a chapter of various artistic expression. In fashion, historic art thinking which predominated the period are source of optional inspiration not simply being generated, culminated and disappear but layout principles which can reemerge as periodical needs. In other words, the past styles are the source of inspiration of new trend of the present time and will serve as the text that give birth to yet another trend. In this study, I conducted the research on the layout principles of Modernism Architecture in aspects of pure visibility and the layout characteristics. And I analyzed cases of modern fashion which were appling architectural layout principles in the view point of formal construction dimension. As the result, the layout principles of Modernism Architecture have the characteristics of diagram linearity, geometric planarity and exclusive closing. And I was applying the architectural layout principles of Modernism to fashion. The layout principles of Modernism Architecture have the tendency of lacking history types, abstract plane partition and reductionism purity in fashion. The meaning of this study is follows: The characteristics of art school of thought are given shape by appling & analysing the architectural layout principles of historical art school of thought to modern fashion in the view point of formal construction dimension. The applied possibility of historical art school of thought as the source of inspiration about the fashion design is extended.

One of the shortcomings of seismic bridge design codes is the lack of clarity in defining the role of different seismic isolation systems with linear or nonlinear behavior in terms of R-factor. For example, based on AASHTO guide specifications for seismic isolation design, R-factor for all substructure elements of isolated bridges should be half of those expressed in the AASHTO standard specifications for highway bridges (i.e., R=3 for single columns and R=5 for multiple column bent) but not less than 1.50. However, no distinction is made between two commonly used types of seismic isolation devices, i.e., elastomeric rubber bearing (ERB) with linear behavior, and lead rubber bearing (LRB) with nonlinear behavior. In this paper, five existing bridges located in Iran with two types of deck-pier connection including ERB and LRB isolators, and two bridge models with monolithic deck-pier connection are developed and their R-factor values are assessed based on the Uang's method. The average R-factors for the bridges with ERB isolators are calculated as 3.89 and 4.91 in the longitudinal and transverse directions, respectively, which are not in consonance with the AASHTO guide specifications for seismic isolation design (i.e., R=3/2=1.5 for the longitudinal direction and R=5/2=2.5 for the transverse direction). This is a clear indicator that the code-prescribed R-factors are conservative for typical bridges with ERB isolators. Also for the bridges with LRB isolators, the average computed R-factors equal 1.652 and 2.232 in the longitudinal and transverse directions, respectively, which are in a good agreement with the code-specified R-factor values. Moreover, in the bridges with monolithic deck-pier connection, the average R-factor in the longitudinal direction is obtained as 2.92 which is close to the specified R-factor in the bridge design codes (i.e., 3), and in the transverse direction is obtained as 2.41 which is about half of the corresponding R-factor value in the specifications (i.e., 5).

Several municipal seismic vulnerability investigations have been identified pounding of adjacent structures as one of the main hazards due to the constrained separation distance between adjacent buildings. Consequently, an assessment of the seismic pounding risk of buildings is superficial in future adjustment of design code provisions for buildings. The seismic lateral oscillation of adjacent buildings with eccentric alignment is partly restrained, and therefore a torsional response demand is induced in the building under earthquake excitation due to eccentric pounding. In this paper, the influence of the eccentric seismic pounding on the design demands for adjacent symmetric buildings with eccentric alignment is presented. A mathematical simulation is formulated to evaluate the eccentric pounding effects on the seismic design demands of adjacent buildings, where the seismic response analysis of adjacent buildings in series during collisions is investigated for various design parameters that include number of stories; in-plan alignment configurations, and then compared with that for no-pounding case. According to the herein outcomes, the effects of seismic pounding severity is mainly depending on characteristics of vibrations of the adjacent buildings and on the characteristics of input ground motions as well. The position of the building wherever exterior or interior alignment also, influences the seismic pounding severity as the effect of exposed direction from one or two sides. The response of acceleration and the shear force demands appear to be greater in case of adjacent buildings as seismic pounding at different levels of stories, than that in case of no-pounding buildings. The results confirm that torsional oscillations due to eccentric pounding play a significant role in the overall pounding-involved response of symmetric buildings under earthquake excitation due to horizontal eccentric alignment.

This paper focuses on examining the effects of span arrangements on displacement responses of plan-symmetric RC frame buildings designed using the direct displacement-based design (DDBD) method by employing non-linear analyses and the skew seismic attack. In order to show the desired performance of DDBD design approach, the force-based design approach is also used to examine the seismic performance of the selected structures. To realize this objective, 8-story buildings with different plans are selected. In addition, the dynamic behavior of the structures is evaluated by selecting 3, 7, and 12-story buildings. In order to perform non-linear analyses, OpenSees software is used for modeling buildings. Results of an experimental model are used to validate the analytical model implemented in OpenSees. The results of non-linear static and non-linear dynamic analyses indicate that changing span arrangements does not affect estimating the responses of structures designed using the DDBD approach, and the results are more or less the same. Next, in order to apply the earthquake in non-principle directions, DDBD structures, designed for one-way performance, are designed again for two-way performance. Time history analyses are performed under a set of artificial acceleration pairs, applied to structures at different angles. It is found that the mean maximum responses of earthquakes at all angles have very good agreement with the design-acceptable limits, while the response of buildings along the height direction has a relatively acceptable and uniform distribution. Meanwhile, changes in the span arrangements did not have a significant effect on displacement responses.

The purpose of this paper is to study on the applicability of the standard design response spectrum from the response spectrum analysis method, mainly applied to pile mooring facilities. To this end, after performing the ProShake 1-dimensional site response considering various geological conditions, the current standard design response spectrum was compared, and the ground-pile model in time history and two-dimensional site response analysis using Abaqus were performed to analyze the dynamic behavior of the ground-pile and to examine the selection method of the reference surface of the response spectrum on the installed slope, respectively. As a result, it was confirmed that no problems were found in the applicability of the current standard design response spectrum and no improvements are needed as well when considering the characteristics of the ground-pile dynamic behavior and the slope of the pile mooring facility.

This study was aimed at developing a new textile design based on the authentic and cultural resources of the Gangneung Subo pattern and applying the textile design to knitted fashion products. Gangneung has been recognized for its outstanding artistry in the field of Gyubang art. Gangneung Subo is an embroidered wrapping cloth. The discovered and preserved Subo at this time was from the Kwandong region centered in Gangeung, and is regarded as the product of the indigenous native culture in Kwandong. Therefore, as a representative cultural resource of Gangneung, the Gangneung Subo has sufficient value as a material for the development of cultural products with uniqueness, distinctiveness, and historicality. As a research method, the background of Gangneung Subo was investigated. A total of 12 motifs were created while preserving the authentic originality of the Gangneung Subo pattern and minimizing unwanted deformations of the pattern during the developing process. The created motifs were repeatedly applied to the pattern and new textile designs were created. Eighteen knit fashion products, including narrow and wide-width mufflers and neck warmers, were developed by applying the new textile designs. As a significant cultural resource for cultural goods development, this study ascertained the value of Gangneung Subo, preserving its unique distinction and history. This study was especially significant since the Gangneung cultural goods developed used knitted material and extended the development to producing real products.

This study presents code-compliant seismic details by addressing dry mechanical splices for precast concrete (PC) beam-column connections in the ACI 318-19 code. To this end, critical observations of previous test results on precast beam-column connection specimens with the proposed seismic detail are briefly reported in this study, along with a typical reinforced concrete (RC) monolithic connection. On this basis, nonlinear dynamic models were developed to verify seismic responses of the PC emulative moment-resisting frame systems. As the current design code allows only the emulative design approach, this study aims at identifying the seismic performances of PC moment frame systems depending on their emulative levels, for which two extreme cases were intentionally chosen as the non-emulative (unbonded self-centering with marginal energy dissipation) and fully-emulative connection details. Their corresponding hysteresis models were set by using commercial finite element analysis software. According to the current seismic design provisions, a typical five-story building was designed as a target PC building. Subsequently, nonlinear dynamic time history analyses were performed with seven ground motions to investigate the impact of emulation level or hysteresis models (i.e., energy dissipation performance) on system responses between the emulative and non-emulative PC moment frames. The analytical results showed that both the base shear and story drift ratio were substantially reduced in the emulative system compared to that of the non-emulative one, and it indicates the importance of the code-compliant (i.e., emulative) connection details on the seismic performance of the precast building.

When the pressure at the weak spot established at a certain part of a high pressure vessel or piping system exceeds a design pressure, this weak spot is burst, and the pressurized gas emitted through the weak spot will cause a compression wave system. In this connection, in the present study, an experimental study by using a conventional shock tube facility is performed to estimate the effects of the material of diaphragm, curvature radius and thickness of materials on the valve opening time in diaphragm. Pressure sensor having 500kHz in natural frequency is installed at 35mm downstream of the rupture diaphragm to measure the static pressure history of propagating and being accumulated compression wave. 4 kinds of materials are used as diaphragm that is aluminium, copper, stainless steel and zinc. The diaphragm radii of curvature R are ${\infty}$, 120mm and 60, respectively. And the depth for $90^{\circ}$ groove is 0.04mm. It is found that the smaller the tensile strength and elongation of the rupture diaphragm is, the smaller the radius of curvature of the rupture diaphragm is, and for the same conditions the thinner the thickness of the rupture diaphragm is, the shorter the valve opening time becomes. Also, the tensile strength, elongation and the radius of curvature of the rupture diaphragm for the same conditions are smaller, the maximum pressure rise caused by the coalescences of the compression wave is smaller. Finally the pressure ratio is higher, the valve opening time is shortened and gradient of pressure increment is more steepen.

This paper is the second part of a series of the research about the Teddy boy style which is to examine various fashion changes in subcultural styles in 1900s. The main concern of this research is to investigate the creation and meaning of the Teddy boy style, how it interacted with the elements of class and generation and how the materials needed by the group constructed and appropriated into the visible systematic cultural form of correspondence. The Teddy Boys are the first recognized members of the British youth culture, which is known as the new Edwardian because of their dress. They had created the concept of the "teenagers," which forms the basis of the sense of a "generation" in the 20th century. The Teds set the style that would be used and modified in the following generations. They adopted the Edwardian style of the upper class, and changed it into their own style by modifying it and adding to it some other elements. The Teddy boys style is a special version of the sartorial appropriation encountered in the sphere of the fashion history. It actually began immediately after the war by the upper class youth far from the working class neighborhood. In the late 1953, the elitist aura surrounding the Edwardian suit was suddenly shattered. Within just a few months, the Edwardian suit became a source of social anxiety and the focus of a symbolic battle. Although the Edwardian look had initially went back to the upper class root, it became a symbol of rootlessness. In appropriation of this image, The Teddy boys were also rejecting the sartorial conformism of the English working class with its modest tradition. In this respect, the Teds effected the ascent or fall of the working class in the area of fashion. The Teds dress was not a merely borrowed fashion, but was a bastard fashion in the form of American trends, the Zoot suit. At this time members of the working class possessed only work dress for the week and waist suits for the Sunday outings. Teds broke this pattern, and developed the working class dandyism of wearing clothes simply to show off. The results were that they succeeded in opening the teen market, and popularizing a working class style for the first time in British history. The Teds became the first British street style with ties music, and remain as an symbol of the rising of a new age of values and styles.f values and styles.
