  • The coner high column method that is used in the multi-roof building Sungryemoon seems to have been used for the first time during the Choseon Dynasty, and it's characteristics and trend of usage are studied in this paper. In the results, it was confirmed that the coner high column method is economic and structurally safe, and selectively combines the structural factors used in the Chinese seats. It was found that this method was a newly adopted construction method to effectively express the authority of the country with the establishment of a new dynasty. Also the meaning of the method could be guessed since it was continuously used in important structures from the Choseon Dynasty to the Daehan Empire, in spite of the new multi-roof building technologies.

  • This study introduces a novel 'multi-mushroom' structural system designed to improve seismic performance in lowrise buildings. Traditional low-rise structures tend to favor sliding over rocking due to their smaller aspect ratios despite the rocking system's superior seismic response reduction. Rocking designs allow structures to pivot at their base during seismic events, reducing damage by dissipating energy. The proposed multi-mushroom system divides the building into four equal sections with small gaps in between, each capable of independent rocking. Numerical analyses are conducted using scaled earthquake records from far- and near-source events to evaluate this system's performance. The results indicated that the multimushroom system significantly reduces plastic hinge formation compared to conventional designs. The system also demonstrated enhanced beam performance and a robust base girder, contributing to reduced collapse vulnerability. The 3-story model exhibited the most favorable behavior, effectively mitigating peak roof drift values, where the rocking system achieved a 21% reduction in mean roof displacement for near-field records and 15% for far-field records. However, the 5-story configuration showed increased roof displacement, and the 7-story model recorded higher incidences of collapse prevention (CP) hinges, indicating areas for further optimization. Overall, the multi-mushroom system enhances seismic resilience by minimizing plastic hinge formation and improving structural integrity. While the system shows significant promise for low-rise buildings, challenges related to roof displacement and inter-story drift ratio in taller structures necessitate further research. These findings suggest that the multi-mushroom system offers a viable solution for seismic risk reduction, contributing to safer and more sustainable urban development in earthquake-prone areas.

  • Building-Integrated Photovoltaics (BIPV) is a photovoltaic (PV) technology which can be incorporated into the roofs walls of both commercial and domestic buildings to provide a source of electricity. BIPV systems can operate as a multi-functional building components, which generates electricity and serves as part of building envelope. It can be regarded as a new architectural elements, adding to the building's aesthetics. Applying PV modules on roof has an advantage over wall applications as they seem to receive more solar radiation on PV modules. There are various types of PV applications on building roofs: attached, on-top and integrated. This paper describes the classification and characteristics of PV applications on roofs.

  • Building integrated photovoltaic(BIPV) system operates as a multi-functional building construction material. They not only produce electricity, but also are building integral components such as facade, roof, window and shading device. As PV modules function like building envelope in BIPV, combined thermal and PV performance should be simultaneously evaluated. This study is to establish basic Information for designing effective BIPV by discovering relations between temperature and generation capability through experiment when the PV module is used as roof material for houses. To do so, we established 3kW full scale mock-up model with real size house and attached an PV array by cutting in half. This is to assess temperature influence depending on whether there is a ventilation on the rear side of PV module or not.

  • The results of examining the architectural features and changes of the main building of Dogapsa temple which is multi roofs wooden structure are as follows. The passage comparing 'Dogapsa' of <>, account of Lee Ha Gon's trip as the literature showing the appearance of Dogapsa temple in the early 18th century to Borimsa through verse of 'Dutacho' was noticeable. Dogapsa temple at Yeongam was distant over 100 ri from Borimsa temple at Jangheung and it was considered that there were many temples at Mt. Wolchul, Yeongam and there were also many temples to be comparable with it. But, Dogapsa temple was compared to Borimsa temple because verses 'many-storied building is high and immense' of 'Dogapsa' at <> and 'Dogapsa is lower than Borimsa at Jangheung' at 'Dutacho' of <> were interpreted as the existence of multi roofs Buddhist temple which had something in common with Dogapsa and Borimsa and was comparable to them. According to existing materials, it was assumed that the main building of Dogapsa was burnt through the Japanese invasion of Korea in the 52nd year of the sexagenary cycle (Eulmyooebyeon, 1555) and Jungyujaeran (1597), but record of major history of the main buildings of Dogapsa and Borimsa indicated that multi roofs wooden structure of the two temples were built at the same period. Since multi roofs wooden structure of main building of Borimsa was rebuilt in 1692, these buildings existed from the early 18th century to middle 18th century.

  • 구조물의 내진 성능을 정확히 평가하기 위해서는 비선형 시각 이력 해석이 필요하지만 실용성과 단순성 측면에서 약산법이 대안이 될 수 있으며, 다층 구조물을 등가 단자유도계로 치환할 때 다층 구조물의 모드벡터는 구조물이 탄성 또는 탄소성 상태에 상관없이 탄성 상태에서의 모드 형상으로 가정되지만, 항복이 발생한 후 증가하는 하중단계에서 구조물은 비탄성으로 되기 때문에 변위 모드 특성들도 변화된다. 본 논문은 항복 이후의 구조물의 모드 변화를 고려한 비선형 변위모드를 이용하여 다자유도계를 등가 단자유도계로 변환하는 방법을 제시하였으며, 변환된 등가 단자유도계의 변위응답을 근거로 추정한 복합 구조물의 최상층 변위와 실제 지진교란을 받는 복합 구조물의 비선형 동적해석에 의한 최상층 변위를 비교함으로서 복합구조물의 지진응답예측을 위한 비선형 변위모드법의 적용성과 신뢰성을 검토하였다.

  • Roof greening recently emerged to be an important issue of environmental policies in a city. To cover roofs of buildings with green vegetation gives chances not only to improve urban environmental function but also provides the opportunities of environmental learning and convenience for users in the building. This study aimed to give directions for roof greening plan to designers by acknowledging the relationships between ecological and utilizational effectiveness. 10 sites and 15 variables were adopted to measure the relationships. As a result, no positive correlations was found between them. One of the results in correlation analysis among variables, however, showed that the roof gardens have high utilizational effectiveness only when a green roof was made by focusing on ecological functions in addition to the concepts that will guarantee user's convenience such as accessibility, entrance and exit, facilities for convenience and learning. The results implies that a green roof has to be designed considering multi-functional effects. Correlation between species of vegetation and the number of daily users, average staying hours, and attending level for environment educational programs were not significant. These findings imply that when a green roof has to be take high utilizational effectiveness, both plentiful vegetation species and design concepts for users' convenience are should be considered.

  • Green roofs are gaining much interest in many cities around the world due to its multi-purpose effects of water conservation, flood mitigation and aesthetic benefits. However it may cause additional water demand to maintain green plants, which may intensify the current and future water shortage problems. While ordinary concrete roofs and normal green roof drains off rain water, concave green roof system can retain rain water because of its water holding capability. In this study, the water conservation effect of concave green roof was compared to normal roof on #35 building in Seoul National University, Seoul, Korea. For seven rainfall events the amount of stored rainwater and runoff were measured and proved water conservation effect of the concave green roof system. The concave green roof system of which area is 140m2 showed effect of water conservation from 1.8ton to 7.2ton and the most influence factors on water conservation in green roof are rainfall and antecedent day. If this concave green roof is applied to many buildings in the cities, it is expected as a way to water conservation through rainfall storage.

  • The purpose of this study is to present rational methods of multi-criteria optimization of the envelope of buildings. The object is to determine the optimum R-value of the envelope of a building, based on the following criteria: minimum building costs (including the cost of materials and construction) and yearly heating costs. Mathematical model described heat losses and gains in a building during the heating season. It takes into consideration heat losses through wall, roof, floor and windows. Particular attention was paid to have a more detailed description of heat gains due to solar radiation. On the assumption that shape of building is rectangle in order to solve the problem, optimum R-value of the envelope of a building is determined by using non-linear programing methods(Kuhn-Tucker Conditions). The results constitute information for designers on the optimum R-value of a building envelope for energy saving buildings.
