오늘날 도시공간에 건축되는 건축물은 건물사이 공간을 크게 확보하여 건물내부에 충분한 일광을 얻도록 노력하고 있으며, 건물의 일조량은 건물의 높이뿐만 아니라 건물간의 간격이 매우 중요하다. 하지만 오늘날 고밀도 개발로 인하여 건물사이 간격을 충분하게 확보할 수 없고 쾌적한 거주환경에 대한 요구가 강해지면서 일조권 분쟁이 증가되고 있다. 따라서 본 연구에서는 LiDAR 자료와 수치지도를 연계하여 3차원 국토정보를 구축한 후 일조권분석에 적용하여 다음과 같은 결론을 얻었다. 태양의 고도와 방위각을 이용하고 3차원 도시공간을 정확하게 시뮬레이션하여 각각의 세대별 일조권을 총 일조시간과 연속 일조시간으로 구분하여 정량적으로 분석함으로서 일조권 침해 여부를 보다 정밀하게 판단할 수 있는 방법을 제시하였다. 3차원 국토정보를 이용한 일조권분석방법은 지자체에서 도시계획 및 건축 인허가 업무를 수행할 때 보다 정확한 자료를 제공하여 줄 것으로 판단된다.

With regard to the pavilion buildings of Imcheonggak Gunjajeong and Donglakdang Gyejeong that are located within residential areas, this study focused on the construction background, the building owner's circumstances and the location environment of these buildings, and attempted to derive the architectural characteristics presented by these two pavilion buildings and, through this, to grasp the architect's intention of plan. The results of this study are as follows. With regard to Gunjajeong, it could be confirmed that, first, it is located in a propitious site and took the composition that follows the family ritual standards for the family rituals of the scholar-gentry class and opens to visitor access, and second, the floor height of the site and interior space was designed so that Munpilbong on the south and the Sarangchae on the west, and the Sadang on the east can be connected visually, and third, the authority and dignity of the head family were built through the symmetric 丁-shaped plane figure, the wide partition module, the form-centered building, and the hierarchical composition of the roof. On the other hand, with regard to Gyejeong, it could be confirmed that, first, it is located along the stream of Jagye valley that has no mountains in the front and in the back and took the composition that put the name symbolizing Taoist thoughts on the surrounding natural environment and was closed to visitor access but opens to nature, and second, with Jagye and Jagye surroundings as the main landscape, it built the concept of intended landscape that symbolizes the Taoist thoughts by giving names not only simply to the visible objects but also to surrounding rocks, and third, the asymmetric ㄱ-shaped plane composed a yard-centered space rather than emphasizing the shape, and connected the part of the plane with Jagye so as to be embodied as a personal inner self-perfecting place that closely communicates only with nature away from the mundane world.

본 논문은 전단머리를 갖는 CFT기둥-RC 무량판 접합부에 대한 실물대 실험연구를 요약한 것이다. CFT구조는 여러 가지 구조 및 시공 상의 장점으로 인하여 국내 건설현장에서 상대적으로 짧은 시간에 폭넓게 수용되고 있다. 한편 RC 무량판 구조는 층고절감 및 공기 단축 측면의 장점으로 국내의 지하주차장이나 주거용 건물에 필수적 구조시스템으로 널리 사용되고 있다. 이 두 구조시스템을 조합함으로써 공사기간의 획기적 단축 등 여러 시공 및 구조상의 이점을 극대화할 수 있을 것으로 예상된다. 그러나 CFT기둥-RC 무량판 접합부의 효율적인 디테일은 국내 외적으로 아직 충분히 연구된 바가 없어서 이 분야의 연구가 매우 필요한 실정이다. CFT기둥-RC 무량판 접합부의 구조성능에 영향을 미칠 수 있는 여러 가지 변수를 고려하여 접합상세를 제안하고 실험을 통하여 검증하였다. 실험결과 본 연구에서 제시된 CFT기둥-RC 무량판 접합상세의 펀칭강도는 ACI에서 규정한 RC 무량판 펀칭강도와 동등하거나 상회하는 것을 확인할 수 있었다. 실험결과를 토대로 CFT기둥-RC 무량판의 펀칭전단강도 예측식을 제안하였다.

건물의 높이와 세장비가 증가함에 따라 건물의 최대 횡변위와 풍응답 가속도와 같은 사용성 요구조건을 만족시키는 것이 고층건물 구조설계에 있어서 중요한 설계요소가 되고 있다. 풍응답 가속도는 거주자에게 불쾌함을 유발시키는 직접적인 원인이 되지만, 초기 구조 설계단계에서 구조 설계자가 풍응답을 조절할 수 있는 실용적인 방법은 개발되어 있지 못하다. 본 연구에서는 재분배기법을 이용하여 건물의 강성을 조절함으로써 고층건물의 풍응답 가속도를 조절할 수 있는 방법을 제안하였다. ASCE 7-02, NBCC 95, ISO 6897 등의 설계 코드 및 기준에 의하면 고층건물의 풍응답 가속도는 1차 고유주기에 반비례한다는 사실에 근거하여 본 연구에서는 물량을 재분배하여 건물의 1차 고유주기를 조절함으로서 풍응답 가속도를 조절하는 실용적 풍응답 가속도 조절 설계법을 제안한다. 제안된 설계법은 42층 건물의 풍응답 가속도 조절 설계에 적용하여 그 적용성과 효율성을 평가하였다.

This paper deals with 111 buildings built between 1962 and 1987, from various parts of the city of Osijek, for which, through the collection of documentation, a database is created. The aim of this paper is to provide the first steps in assessing seismic risk in Osijek applying method based on vulnerability index. This index uses collected information of parameters of the building: the structural system, the construction year, plan, the height, i.e., the number of stories, the type of foundation, the structural and non-structural elements, the type and the quality of main construction material, the position in the block and built-up area. According to this method defining five damage states, the action is expressed in terms of the macroseismic intensity and the seismic quality of the buildings by means of a vulnerability index. The value of the vulnerability index can be changed depending on the structural systems, quality of construction, etc., by introducing behavior and regional modifiers based on expert judgments. Since there is no available data of damaged buildings under earthquake loading in our country, we will propose behavior modifiers based on values suggested by earlier works and on judgment based on available project documentation of the considered buildings. Depending on the proposed modifiers, the seismic vulnerability of existing buildings in the city of Osijek will be assessed. The resulting vulnerability of the considered residential buildings provides necessary insight for emergency planning and for identification of critical objects vulnerable to seismic loading.

This study aims to evaluate the residential exterior environment and ascertain the factors having an effect on the visual environment viewed through the living room window. This study is based on a questionnaire on the exterior environment targeting residents living in the area of Nohyunng in Jeju city, Jeju-do. The results are as follows. First, residents are satisfied with the exterior environment as a whole; however, the longer-term residents' level of satisfaction is found to be relatively low while dissatisfaction is high. Additionally, there is a difference in satisfaction and dissatisfaction levels between the residents in their own housing and those in rental housing. The residents living in rental housing were found to have a relatively low level of satisfaction and high dissatisfaction. Second, in the case where the living room window faces roads, low satisfaction and high dissatisfaction levels with the visual environment were found, where the living room is on the first or second floor. Third, satisfaction and dissatisfaction with the exterior environment have a close correlation to the impression or nature elements of 26 questions but they show low correlation in size, height, color, design, traffic, artifact elements. Finally, as a result of extracting the factors influencing satisfaction and dissatisfaction with the visual environment, four factors were extracted including "Impression & Nature factor", "Building factor", "Design factor", and "Traffic volume & Artifacts factor". "Impression & Nature factors" is the most influencing factor with satisfaction and dissatisfaction and "Traffic volume & Artifacts factor" was found to have an effect on satisfaction, but not as clearly on dissatisfaction.

Building energy consumption takes up almost 25% of the total energy consumption. Therefore, diversified ways, such as improving wall and window insulation, have been considered to reduce building energy consumption. Recently, green roof system has been explored as an effective alternative for dealing with reducing heating and cooling energy, thermal island effect and improving water quality. However, recent studies regarding a green roof system have only focused on building energy reduction without considering the applied usage, location, and story of the green roof system. Therefore, this study pays attention to the heating and cooling energy in relation to the applied usage, location, and story of a green roof system for investigating its impact on energy reduction. The result of simulations show that the reduction in heating energy consumption is higher when applied to Cherwon-gun province which has a continental climate condition, compared to the city of Busan that is distinguished by its warm climate. Cooling energy saving turns out to be higher when the green roof system is applied to Busan in comparison with Cherwon. As for the applied usage or function of the building, residential space acquires the highest heating and cooling energy saving effect rather than commerce, educational or office space because of HVAC's running time based on usage. When it comes to the story of the green roof, both heating and cooling energy saving become the highest when the green roof is applied to single-storied buildings. The reason is that single story building is affected by the ground largely. Generally, the variations of heating energy consumption are larger than the cooling energy consumption. The outcome of the simulations, when a green roof system is applied, indicates that the energy consumption reduction rate is dynamically responding to the applied usage, location, and story. Therefore, these factors should be counted closely for maximizing the reduction of energy consumption through green roof systems.

The need for eco-friendly building materials such as engineered wood has increased to reduce carbon emissions. Although the range and height of engineered wood buildings are gradually increasing in North America and Europe, engineered wood is mainly used for low-rise residential buildings in Korea. In order to reduce carbon emissions more, therefore, it needs to expand the use of engineered wood by applying it to various buildings with different uses or more stories. With this background, the aim of this study is to investigate the applicability of engineered wood for 9-story office buildings. Since a 9-story building with engineered wood only is not allowed in KBC, an example building has RC ordinary shear walls as the lateral force resisting system while engineered wood is only used for gravity load resisting moment frames. Another example building is also used for comparison where both lateral and gravity load resisting systems are designed by RC. The applicability of engineered wood is investigated by comparing the seismic performance and the amount of carbon emission of both buildings. The result shows that the seismic performance of both buildings was not significantly different while the amount of carbon emission of the engineered wood building was much less then the RC building. Based on this result, engineered wood is sufficiently applicable to 9-story office buildings even though it still needs to pay attention to the shear design of reinforce concrete walls.
