Many studies on the application of stainless steels as structural materials in buildings and infra-structures have been performed thanks to superior characteristics of corrosion resistance, fire resistance and aesthetic appeal. Experimental investigation to estimate the ultimate strength and fracture mode of the fillet-welded connections of cold-formed austenitic stainless steel (STS304L) with better intergranular corrosion resistance than that of austenitic stainless steel, STS304 commonly used has carried out by authors. Specimens were fabricated to fail by base metal fracture not weld metal fracture with main variables of weld lengths according to loading direction. All specimens showed a block shear fracture mode. In this paper, finite element analysis model was developed to predict the ultimate behaviors of welded connection and its validity was verified through the comparison with test results. Since the block shear behavior of welded connection due to stress triaxiality and shear-lag effects is different from that of bolted connection, stress and strain distributions in the critical path of tensile and shear fracture section were investigated. Test and analysis strengths were compared with those by current design specifications such as AISC, EC3 and existing researcher's proposed equations. In addition, through parametric analysis with extended variables, the conditions of end distance and longitudinal weld length for block shear fracture and tensile fracture were suggested.

Alongside the increasingly larger domestic construction projects is the gradual rise in construction waste. Consequently, serious environmental problems emerge. The increase in demand for housing remodeling due mainly to the increase in national income and improvement of quality of life is the main reason for the increase in construction waste. This study was conducted as the basic study for the prevention and reduction of construction waste generated by apartment remodeling; it aimed at identifying the remodeling items and reasons. Toward this end, this study targeted apartments at least 15 years old and conducted a questionnaire survey to determine the remodeled sections and remodeling reasons. As a result of the questionnaire survey, the bathroom, floor finishing, and kitchen furniture recorded the highest ratios in remodeling. Old materials, aesthetic motivation, and pleasant living space composition were cited as the major remodeling reasons. This study is significant as a basic study for generating environmental and economic profits through systematic waste management. Further studies should develop guidelines suitable for construction waste reduction and recycling in line with the construction and demolition phases in case of remodeling.

The purpose of this paper is to research Gunnar Asplund's Woodland Chapel (1918-20) in terms of the revernacularization of classicism and to investigate into the matter of the constructional logic. The term 'revernacularization of classicism' was used by Alan Colquhoun to explain the process to return to the pure sources of classical architecture, and the case of a successful fusion of classicism and vernacular traditions was suggested by Demetri Porphyrios through Scandinavian Doricist sensibility in the early 20th century. Porphyrios's classicism, not as style but as sensibility, is premised on a constructional logic of vernacular, and is to achieve an aesthetic quality by its mythical elaboration. Woodland Chapel, a representative of the Scandinavian Doricism according to him, illustrates characteristics of the revernacularized classicism as in the fact that it thickly displays vernacular images at the same time as relying on classicism; in the return to primitive simplicity; and in the mythopoeic power. However, the constructional logic of this building was obscured in the capital of the portico columns, the interior dome, and the whole structure of the roof. Confronting this paradox, we have to remember that although Porphyrios emphasized the constructional logic he opened an aesthetic exit of the mythical elaboration, which is in accord with the concept of the tectonic as the poetics of construction. Woodland Chapel assumes atectonic features but is never anti-tectonic. Asplund intensified a poetic effect by setting the myth over construction in the chapel, and so it can be seen as a key example of the revernacularized classicism with the Doricist sensibility.

The structural aesthetics of architecture are becoming an inspirational source for many fashion designers and have been reborn in structural fashion. This study planned to analyze the method of expression of structural aesthetics expressed in modern structural fashion design and the construction method to maximize such an effect on the basis of the construction characteristic of Santiago Calatrava as the representative architect of the structural aesthetic. According to the study, the structural aesthetics expressed in modern structural fashion design are as follows: 1) The symbolical formative aesthetic expressed by symbolical inference and analyzation; 2) the dynamic beauty of physic expressed by visual emphasis and dynamics; and 3) the asymmetric beauty of symmetry expressed by metastasis toward the boundary between balance and imbalance. In addition, to maximize structural aesthetics, we used repetition and a progressive technique based on rhythm, asymmetry, and incision-based variances, such as balance, polygon flux, and inference, and analyzation-based distortion as the structuring principle. The following expression methods for maximizing structural aesthetics were found: 1) symbolical and structural exaggeration of appearance; 2) detail technique expansion and material property diversification; and 3) the three-dimensional transformation of structure and shell expression. Structural fashion design was found to have maximized structural aesthetics by using such expression methods to secure artistic esthetics, destroy existing shapes and patterns, and create unique shapes.

Timber structures are susceptible to moisture, contamination, and pest infestation, which can compromise their integrity and pose a significant fire hazard. Despite these drawbacks, timber's lightweight properties, eco-friendliness, and alignment with current architectural trends emphasizing sustainability make it an attractive option for construction. Moreover, timber structures offer economic benefits and provide a natural aesthetic that regulates building temperature and humidity. In recent years, timber domes have gained popularity due to their high recyclability, lightness, and improved fire resistance. Researchers are exploring hybrid timber and steel domes to enhance stability and rigidity. However, shallow dome structures still face challenges related to structural instability. This study investigates stability problems associated with timber domes, the behavior of timber and steel hybrid domes, and the impact of timber member positioning on dome stability and critical load levels. The paper analyzes unstable buckling in single-layer lattice domes using an incremental analysis method. The critical buckling load of the domes is examined based on the arrangement of timber members in the inclined and horizontal directions. The analysis shows that nodal snapping is observed in the case of a concentrated load, whereas snap-back is also observed in the case of a uniform load. Furthermore, the use of inclined timber and horizontal steel members in the lattice dome design provides adequate stability.

건축디자인을 평가하는 방법에는 상당히 맡은 요소를 고려 할 수 있다. 기능성, 구조성, 형태, 환경 등 다양한 요소를 고려하여 최종의 디자인을 생산해 낸다. 여기서 computer와 같은 자동화된 기계에 의해서 디자인이 생성된다면, 그 결과는 경우에 따라서 무수히 맡아 우리 인간의 평가 능력 범위를 넘는 수 가 있다. 따라서 디자인을 자동으로 생산할 뿐 만 아니라 자동으로 최선의 결과물을 자동적으로 평가하여 선택하는 것도 상당히 중요하다. 본 논문에서는 상기에서 언급한 요소 중 미학적 특성을 기계가 자동으로 평가하여 최적의 결과물을 선택할 수 있도록 평가 방법을 제시하였다. 평가 방법은 고전적으로 내려오는 미적 평가방법의 하나인 질서와 무질서의 상관 관계를 측정하는 것으로 이는 형태요소와 공간관계를 나타내는 형태 디자인 지식의 스키마적 표현을 적용한다.

Various decorative patterns and sculptures found in antique architectures like palace architecture and temple architecture are not only valuable assets of our culture but have religious meaning at the same time and show aesthetic aspiration and desire of Korean people. In this study, potential application of patterns in textile industry is suggested based on the reconstructed and patternized geometric patterns of window grids, a decorative element in architecture, and stair and stair somaetdol, a architectural element in Buddhist temples, using Photoshop and Illustrator program of Adobe INC AND Tex-pro program of Youngwoo CNI INC. All around the world today, efforts to reinterpret unique and antique architectures and cultural assets in a modern way has been increasing. Decorative patterns displayed in Buddhist temple architectures which are antique Korean architectures have excellent geometric aesthetic value. And the development potential of patternizing these elements into modern designs is high. Therefore, it is thought to be possible to develop high value-added fabric and to develop various fashion items including apparel and interior decoration based on modern reinterpretation of patterns of window grid and decorative elements of stairs and stair somaetol that are part of our antique architectures.

Exaggerated expressions of contemporary fashion have exceeded historical precedents in volume. The purpose of this study is to understand the aesthetic characteristics of expanded form In contemporary fashion. To take dresses beyond their flat shapes into three-dimensional forms, it was investigated into volume of dresses by using the void and the mass. The void Is rarefied space and the mass is densified space. The void of dresses could be constructed from the boning such as panier and stiff textiles as organza lining. The mass could be constructed from padding. Fold, pleats, twist, and the layering of fabrics show features of both the void and the mass. Contemporary fashion designers relied on the void rather that the mass to make the enormous volume because of the weight of the mass. X-silhouette and the expansion of skirt and sleeve were dominant as the result of accentuating the body with a waistline. However, many of expanded dresses were so voluminous that they obscured the body's outlines. Some forms were strange and shocking. Many designers explored the void and there were a multitude of methods to construct the void: compartments of air, architectural techniques, technical textiles, fold such at origami. The aesthetic consciousness of expanded dresses could be classified into 7 categories, the giant, the dynamic, the deconstructive, the historical, the comedic, the rhythmical, and the technical character.

There is much architectural and engineering literature which discusses the virtues of exterior bracing and diagrid systems in regards to sustainability - two systems which generally reduce building materials, enhance structural performance, and decrease overall construction cost. By surveying past, present as well as possible future towers, this paper examines another attribute of these structural systems - the blend of structural functionality and aesthetics. Given the external nature of these structural systems, diagrids and exterior bracings can visually communicate the inherent structural logic of a building while also serving as a medium for artistic effect. Viewed in this light, the visual appeal of these systems can be enhanced to give a tower a more distinct urban identity. This entails the creation of structural elements that are aesthetically pleasing, geometrically coherent and that demonstrate dexterity of application in regards to a building's composition, while also respecting the laws of physics and mechanics. In this fashion, an artistic approach can exhibit structural systems as not just purely rational features that enable the construction of tall buildings, but as important visual components that afford opportunities for creative expression. This paper, therefore, synthesizes the concepts of structural performance and creative artistry to facilitate a better understanding of the aesthetic developments in skyscrapers worldwide.

We have focused on the building appearance according to the change of conservation policy and urban fabric in Bukchon, Seoul. The Urban Hanok, urban traditional housing type, had been evolved in modern contort from 1920's to 1960's, that is to say, many buildings(Urban Hanok) in Bukchon area has built up with a lot and road at the same time. But the change of conservation policy has an effect on the urban fabric and building(wooden structure, RC and brick building). Thus many types of building in Bukchon has undergone a various change. The purpose of this paper is to define a change factor of Bukchon buildings. Thus we need to pay attention to policy and urban fabric. We reached the result as follows. First, the change of architecture regulations according to the several policies(an aesthetic area, an altitude area for sky line restriction and so on) brought into building deformation and eventually the historic scenery of Bukchon has been spoiled. Second, the change of policy had an effect on the change of roads and lots. Buildings on a widen road and a united lot was built newly. But new buildings built up with a concrete or brick structure was not in harmony with the historic scenery of Bukchon area. Third, a development method of a large lot with lack prudence(disregarded a scale and size of lot) did damage to Urban hanok and urban fabric. With the understanding on the relationship of buildings, a urban fabric and a policy in Bukchon, we can define the identity and correspond with the urgent request for a the conservation of historic urban scenery In addition we can suggest the policy and the design guidelines for the reservation and rehabilitation for Bukchon, Seoul.
