Chinese traditional patterns, which are part of our national precious heritage, have a long history. Tiger culture plays a very important role in folk art. In modern society, it is a symbol of human spirit and morality. The tiger pattern is also a unique traditional pattern in Chinese folklore. From the Spring and Autumn period to modern society, the tiger pattern has evolved in form through thousands of years of development. It is also a representative intangible cultural heritage in contemporary times. It plays a special role in the cultural exchange of different regions, resulting in the generation of the creation of folk art with great local characteristics. Therefore, traditional tiger patterns are an important part of traditional Chinese folk culture and art. In this study, by analyzing the development and evolution history of Chinese traditional tiger patterns, the application methods of Chinese traditional tiger patterns were summarized, the rich cultural connotation, artistic characteristics and application of traditional tiger pattern in modern fashion design were discussed. In contemporary design, the new and improved tiger pattern styles were explored, intangible cultural heritage was interpreted and inherited, and the cultural and artistic values contained therein were extracted. The author combined with modern fashion design, according to people's aesthetic taste and design principles, it is recreated,so that the traditional pattern has certain characteristics of The Times.But at the same time it retains its original character,and the traditional tiger pattern was inherited and the cultural connotation of clothing design was enriched.

This paper is a study of the Beaux-Arts discipline of architecture, as it was established during the late nineteenth century in America. It focuses on trio particular modes of vision and representation that were at the heart of the discipline. The paper argues that Beaux Arts vision was centered on what may be called 'planar vision'; a mode of seeing through which the multiple aspects of the architectural design imbedded in the plan were read and re-interpreted. Similarly Beaux-Arts training in drawing required its student to draw within the multiple layers of historical traces; the new design being in effect a new layer placed on often unseen traces of monumental precedent. The theoretical basis of this practice was not based on history but on the concept of composition. Composition, in the French tradition was regarded more a matter of practice than theory. The Anglo-American discourse on composition, on the other hand, formed a body of theoretical literature based on formalist assumptions. There was, however, a fundamental gap between these formalist theories of composition and the 'layered' modes of vision and drawing involved in the design process. This practice leaned more on the modern romantic notion of 'intuition' for its theoretical basis, once again forming an immanent conflict with the mimetic practice of classical and historical architecture. The paper draws a picture of a discipline centered on a 'theory of the plan,' a potentially modern discipline integrated with classical forms and details. It was clearly effective as a practice. However, structured by conflicts between theory and practice, history and form, mimesis and intuition, the Beaux-Arts was unable to defend itself at the philosophical and theoretical level the modernists engaged their attacks on this system. At the same time, the paper poses the question of how different modern architecture is from this system. Is not the 'theory of plan,' in its many transformations and guises, still the central discipline of twentieth century modern architecture, and is it not structured by basically the same kind of conflicts and paradox that were immanent to the Beaux-Arts system.

The remarkable fact regarding the History of Chosun Dynasty(from Jungjong- Youngjo) is that any slightest evidence can't be found that Pobeckchuck was used to measure clothes or various Pobecks. There remains the document that in the 22nd years of Myeonjong, Japan required that Pobeckchuck be used, but it couldn't be allowed because of the reason it was made in the former king. This fact raises the high possibility that Pobeckchuck could be the most trustworthy standardized ruler at that time, and in other point of view, it can be presumed that the measurement in the period of King Sejong continued to have been used until this time. It can be seen that the length of one Chuck of Pobeckchuck at this time must have been equivalent to 46. 73cm of Pobeckchuck of Samchuck in the period of Sejong. In the History of Sunjo Period, many records on Pobeckchuck can be found, which fact seemed to have rectified the measurement system which was disordered by military revolt, though the reason is not clear. Also a record can be found that in the period of Sunjo, Chinese envoy required the Sunjo Regime to use Pobeckchuck for the measurement of copper pillar, which record supports the fact that Pobeckchuck is the standardized ruler. Another record that in the 26th period of Youngjo, Pobeckchuck of Samchuck was corrected according to the Kyeongkukdaejeon shows that the length of Pobeckchuck was 46.80cm at that time. Also, the record which rectified many rulers with the comparison of Hwangjong-chuck, Ju-chuck, Joryeki-chuck, Yongjo-chuck, etc. with one another reveals that the rulers used in the period of Sejong continued to have been used unchanged until in the period of Youngjo.

In the design of a sky-bridge, repetitive boundary nonlinear time history analyses are required to accurately predict dynamic behaviors of the connected buildings because the connection systems of a sky-bridge usually have high nonlinearity. If a conventional finite element model for entire high-rise buildings is used for repetitive boundary nonlinear time history analyses, computational efforts could be significant. In this study, an equivalent cantilever model considering the belt-wall effect has been proposed for an efficient dynamic analysis and a performance evaluation of vibration control of high-rise buildings connected by a sky-bridge. To verify the accuracy and efficiency of the proposed equivalent model, boundary nonlinear time history analyses of 49- and 42-story example buildings connected by a sky-bridge have been performed for wind excitation. Based on the analytical results, it has been verified that the proposed equivalent model can provide accurate dynamic responses of building structures connected by a sky-bridge with significantly reduced computational efforts.

In recent years, time history analysis has been the method generally used for the seismic analysis of tall buildings with damping devices. When T is the natural period of the first vibration mode of the structure, the sum of the spectral acceleration of the earthquake ground motion is usually adjusted to that of the design response spectrum in the period ranging from 0.2T to 1.5T to meet the requirements of design code. However, when the ground motion is scaled according to the design code, the differences in the responses obtained by response spectrum analysis (RSA) and time history analysis (THA) of the structures increase as the natural period of the structure becomes longer. When time history analysis is performed by using ground accelerations that are scaled according to the design code, base shear is similar to that obtained from RSA, but other responses, such as displacements, drifts and member forces, are underestimated compared to RSA. If these results are adjusted by multiplying with the scale-up factor, the scaled responses become much smaller. Therefore, a scaling method of ground motions corresponding with the design code is proposed in this study, as a way of assisting structural engineers in generating artificial ground motions.

This study aims to optimize, design, and predict the MTMDs performance in SDOF systems using spectral analysis, and then apply their results to MDOF structures. Given the importance of spectral analysis in the design of new engineering structures, achieving a method for designing TMDs based on this theory can be of great importance for structural designers. In this study, several convenient combinations of MTMDs in an SDOF system are first considered to minimize the maximum displacement. For calculating the frequency ratios of dampers, an innovative technique is adopted in which the values of different modal responses obtained from the spectral analysis are approached together. This procedure is done using a harmony search (HS) algorithm. Also, using the random vibration theory, the damping ratio of the dampers is obtained. Then, an equation is presented for predicting the performance of MTMDs. For evaluating this equation, three structures with different stories are designed. Some of the presented combinations of dampers are added to them. The time history analyses are employed to analyze the structures under 30 different accelerograms. The findings indicated that the proposed equation could efficiently predict the performance of the MTMDs. Furthermore, four different patterns of damper distribution along the height of the structures are defined. The effect of them on the maximum deformation of the structures in time history analyses is discussed, and an equation is presented to estimate this effect. The results indicated that the average and maximum error percentages of the proposed equations are about three and seven percent, respectively, compared to the time history analyses results, which are negligible values.

Recent years, direct displacement-based design (DDBD) procedure is proposed for the design of un-bonded posttensioned (UPT) concrete wall systems. In the DDBD procedure, the determination of the equivalent viscous damping (EVD) ratio is critical since it would influence the strength demand of the UPT wall systems. Nevertheless, the influence of EVD ratio determination of the UPT wall systems were not thoroughly evaluated. This study was aimed to investigate the influence of different EVD ratio determinations on the DDBD procedure of UPT wall systems. Case study structures with four, twelve and twenty storeys have been designed with DDBD procedure considering different EVD ratio determinations. Nonlinear time history analysis was performed to validate the design results of those UPT wall systems. And the simulation results showed that the global responses of the case study structures were influenced by the EVD ratio determination.

The Bauhaus educational method gave the strong influences on Modern Japanese art and design education. In the 1920s and 1930s, Japan allied with Germany and Italy politically and tried to receive German system to be modernized. The reception of the Bauhaus and Moholy-Nagy's photographic theory was one of those activities at that time. Japanese intellectual class went to the Bauhaus and studied there; Ishimoto Kikuchi, Nakata Sadanosuke, Mijutani Takehiko, Yamawaki Iwao and Yamawaki Michiko(Yamawaki Iwao's wife). Especially, Yamawaki Iwao studied about the architecture at the Bauhaus, but his interest moved toward the photography and the photomontage based on Moholy-Nagy's theory. He studied at the photography workshop of the Bauhaus presented by Peterhans irregularly. Even though Yamawaki Iwao was an architect, he wanted to be admitted as an expert for the photomontage that he particularly studied at the Bauahus as a Bauhaus member. He had presented many articles about the photomontage at the photography magazines in Japan in order to introduce it to Japan since he returned in 1933. Thus, Yamawaki Iwao is the important person when we look back the Modern Japanese design and art history. In Japan, the art and design systems are managed by the Bauhaus educational system until now, and it has become a kind of cultural legacy in Modern Japan; The university of Tama and The university of Tsukuba are the representative educational systems which are based on the Bauhaus legacy. However, Yamawaki Iwao had been concealed as a photographer in Japanese design and photography history until the retrospective discuss named by 'Bauhaus syashin(Bauhaus Photographies)' at the photography magazine, Deja-vu in 1995 and the retrospective exhibition titled as 'Bauhaus syashin(bauahustofografie)' in 1997. This study rethinks of Yamawaki Iwao's historical position while looking at the term as 'Bauhaus Syashin(Bauhaus Photographies)' used in Japan. It is very important to bear in mind Moholy-Nagy's wide variety of approaches to photography at the Bauhaus, but it is impossible to name it 'Bauhaus style'. 'Bauhaus style' is the international style in architecture, but that was never a Bauhaus style in photography. Eugene J. Prakapas indicated that the vague term of 'Bauhaus Photographies' in his article in 1985 as well. This study considers the historical background for the mistake of the term of 'Bauhaus Syashin(Bauhaus Photographies)' in Modern Japanese history, while looking at Yamawaki Iwao's photomontage faintly entering on the historical stage again to discuss the reception of the photomontage from him. In particular, Some of Yamawaki Iwao's photomontage presented as the wall photography in Japan during the Second World War, that was related to the propaganda of Japanese government. It had not been known well in the modern Japanese art and design history because it was related to a declaration of the Second World War by Japan. However, the historical position of his photomontage is very important for Japanese history when we rethink of the reception of the Bauhaus and Moholy-Nagys' photographic theory to build up the Japanese modern history. In the result, this study wants to discuss that the mistake of the term of 'Bauhaus syashin(Bauhaus Photographies)' in Japan is related to the interpretation for the the historical position for Yamawaki Iwao's photomontage in the reception of Bauhaus and Moholy-Nagy's photography in Japan.
