Considering the established research about the characteristics of traditional expression in a contemporary korean architecture, there are two critical problems. the one is that the extent of a case is limited to a public building and a large exhibition building. the other is that the angle of research focus on the viewpoint of specific a level. To settle these problems and supplement a established research, this study is to investigate and analyze the characteristics of popular traditional expression in small commercial buildings. In A viewpoint on the expansion of a case and a various angle, A small commercial buildings is selected as a case. because it is felt that the populace's taste vis-a-vis traditional expression. To investigate and analyze, A main analytic criterion is follows. 1) A expressional method on traditional architectural form 2) A expressional aspect by architectural element 3) A expressional aspect in architectural material 4) A expressional aspect in architectural structure. In consequence we can find out the following results in the process of analysis. 1) In expressional method on traditional architectural form, the traditional expression is represented as the imitation and transformation of a traditional folk house forms, and the embodiment of traditional image 2) In expressional aspect by architectural element, the traditional expression elements is mainly represented at a straw roof and a mud-plastered wall 3) the traditional expression material is mainly straw, timber, small wood boards and mud 4) In expressional aspect in architectural structure, the traditional expression is represented from the viewpoint of decorative expression.

건축문화재의 원형에 대한 이해는 보존 행위의 출발점으로서 매우 중요하다. 본고에서는 원형에 대한 이해를 몇 가지 유형으로 구분해보고, 이를 기반으로 하여 한국의 건축문화재 보존역사에서 특히 목조건축 문화재의 수리공사가 어떻게 진행되어 왔는지를 고찰해보고자 하였다. 한국은 일제강점기 일본인에 의해 수리가 시작되어 일본에서 수리공사 초기에 정립된 방법론의 영향을 직접적으로 받았다. 그 결과 '당초복원'이라고 하는 개념이 해방 이후까지 지속되었다. 한편 일본의 경우 1930년대를 전후하여 현상변경을 신중히 하는 방향으로 전환하면서, 수리공사에서의 조사연구가 강조되고 보고서의 발간이 체계화되었다. 한국의 경우에는 해방 이후 이러한 조사연구에 대한 인식부족과 수리보고서의 발간이 일반화되지 못한 채로, '당초복원'의 방식을 유지하여 형태 위주의 보존에 치중하는 결과를 낳았다. 이는 '유지보존'이라고 하는 방식의 공사에서도 재료의 교체가 일반화되는 결과를 낳았으며, 이러한 이유로 인해 한국의 건축문화재 보존에서 수리공사를 통해 형상은 보존되었으나 원상의 보존에 있어서는 의문이 남는다. 이러한 상황에서 국제적인 보존원칙과 한국적 상황을 고려한 건축문화재의 원형 보존에 대한 논의를 통해 원상의 보존에 대한 기준의 정립이 시급할 것으로 판단된다.

전 세계적으로 탄소중립 2050 실현을 위한 목조 건축물 수요가 늘어나고 있으며, 국내에서도 구조용 직교 집성판(Cross Laminated Timber, CLT)을 이용한 목조 고층 건축물에 대한 기술적 검토가 이루어지고 있다. 본 논문에서는 CLT의 기초 음향성능을 검토하기 위해, 국내산 낙엽송과 소나무로 CLT 슬래브(두께 150 mm)를 제작해 바닥 충격음 차단 성능과 음향투과손실을 측정했다. 실험은 상하로 연결된 페어 잔향실에서 수행했으며, CLT 슬래브에 콘크리트 토핑(두께 50 mm ~ 210 mm, 6조건)을 추가해 차음성능 개선량을 정량적으로 평가했다. 수종에 따른 바닥충격음 차단 성능의 단일수치 평가량을 비교하면, 낙엽송 CLT가 소나무 CLT보다 중량 바닥충격음에서 3 dB, 경량 바닥충격음에서 1 dB 낮았으나, 상부에 콘크리트 토핑을 추가한 조건에서는 수종 간 차이가 없었다. 상부의 콘크리트 층 두께 상승에 따라 중량 바닥충격음이 9 dB ~ 20 dB, 경량충격음이 20 dB ~ 30 dB 저감했다. 이 관계를 면밀도로 분석한 결과, CLT 슬래브의 바닥충격음 차단 성능은 면밀도와 높은 상관관계(R² = 0.94 ~ 0.99)가 있는 것을 확인했다. CLT 슬래브의 음향투과손실은 수종에 따른 차이가 없었다. 면밀도와 주파수로 산출한 음향투과손실 이론치와 실측치의 주파수 특성은 유사하지만 실측치가 8 dB ~ 12 dB 낮아, 보정치를 이용해 실험 대상인 CLT 슬래브의 음향투과손실과 주파수 특성의 관계를 도출했다.

The expediency of using tubular composite steel and concrete columns of annular cross-sections in construction is discussed. The new type space framework with tubular composite columns of multi-storey buildings and its rigid beam-column joints are demonstrated. The features of interaction between the circular steel tube and spun concrete stress-strain states during the concentrical and eccentrical loading of tubular composite members are considered. The modeling of the bearing capacity of beam-columns of composite annular cross-sections is based on the concepts of bending with a concentrical force and compression with a bending moment. The comparison of modeling results for the composite cross-sections of beam-columns is analysed. The expediency of using these concepts for the limit state verification of beam-columns in the methods of the partial safety factors design (PSFD) legitimated in Europe and the load and resistance factors design (LRFD) used in other countries is presented and illustrated by a numerical example.

Physical and chemical factors can cause traditional timber constructions to lose structural integrity. Knowing the dynamic properties of the building components is vital to avoid damage to the buildings from dynamic effects, a subset of physical effects. In this work, spruce and scotch pine wooden beams that had been strengthened in three distinct ways with carbon fiber strengthened polymer (CFRP) were investigated for changes in their dynamic properties. For this, CFRP was used to strengthening unstrengthened wooden beams in the form of bottom confinement, U-shaped confinement, and full confinement after the dynamic parameters of the beams were determined. By using experimental modal analysis with both free-free and fixed-fixed boundary conditions, the beams'initial natural frequencies were identified.

Unconventional with respect for tradition: The Karel Doorman building stands in the heart of Rotterdam's shopping area and is a remarkable combination of restoration and new development. On top of the Ter Meulen shopping centre - a monument of the post-war reconstruction period - we have built an extremely light-weight construction in steel and wood (See Figure 1 & 2). This unconventional building method - at least in the Netherlands - enabled the construction of a 70 metres high 'glass' residential building with 114 apartments and 156 parking places. In this way a remarkable historic Rotterdam building was preserved for the future while at the same time new housing was created on a sheer impossible location, contributing to the quality of life and social safety in this part of the city.

One of engineered woods, glued laminated timber (GLT), can provide a constant level of performance and desired strength even if the quality of wood is low. Due to this fact, there is a growing interest in GLT using domestic species and related research has been carried out continuously. In addition, GLT is popularly being applied to the long-span or high-rise structures overseas. However, KBC 2016 does not allow the engineered woods to be used for middle and high-rise buildings by limiting height. Therefore, a proper design procedure and rationale should be clearly presented by the help of performance-based seismic design. With this background, the goal of this study is to establish a specific procedure for design of a 9-story building with RC shear walls and GLT frames according to the performance-based design of KBC 2016. The performance objectives were set according to KBC and the acceptance criteria for each goal were defined. The RC shear walls and GLT frames were designed by concrete and wood structure requirements, respectively. Analytical models were developed to reflect their nonlinear features, and both nonlinear static and dynamic analyses were conducted. Performance evaluation results showed that the shear walls have insufficient shear strength, so they were re-designed. Consequently, it has been confirmed that GLT frames can be applied to a 9-story office building with the assistance of RC shear walls and performance-based seismic design.

This study focuses on the construction of Gyeongbokgung Palace in the second year of King Gojong's reign, which has been spotlighted for political and economic history. The author analyzed the contents of wood procurement with the Yeonggeon Diary, which records each day of construction site. The results are as follows: First, the 2nd year of King Gojong's reign, Yeonggeon of Gyeongbokgung Palace, was a new building that reflected the old system and 270 years of changed environment on the existing site. Despite the poor economic conditions, it began with years of effort and voluntary volunteer work and dedication. Second, the priority of timber transport was recruiting people in the whole process and the supply and demand of transportation tools. Carrying lumber from the mountains to the riverside and floating it at the right time were all a matter of manpower. Soldiers and carts were used to carry timber that arrived in Hangang River to the construction site. The cart was a consumable product, so it was necessary to continuously use the wood to make cart at the site. Third, fire and flood were the biggest obstacles to the Yeonggeon schedule of Gyeongbokgung Palace. Especially the fire was fatal. It was difficult to extinguish the fire in temporary structure, where was the storage for wood to construct. These disasters greatly affected the construction cost and construction period. Wood procurements of Gyeongbokgung Palace were based on public offerings. At the same time, recycled materials from other palace wood and nearby houses, nationwide buying of private mountain wood, the logging of royal tombs and some of the buildings of Gyeonghui Palace and Changgyeong Palace were relocated.
