The temperature and relative humidity in concrete change with the passage of time depending on factors such as compressive strength. They are also different depending upon internal depth of concrete. In this study, we have measured the change of the temperature and relative humidity in the concrete for two years to act as the parameters to evaluate the concrete durability and effective maintenance.

Recently, two unique high rise buildings have been designed and constructed in Korea. The two buildings, which consist of mega braces and mega columns, are 70-story, 105-story high rise buildings. Through two external structural frame systems, it will be analyzed mechanical and structural characteristic mega column and mega brace system in this report. Particularly, the joint has been studied through the analytical method based on the load transfer mechanism at the point where a mega brace and mega column meets.

가시설 공사는 자연환경에서 영구 구조물에 대한 시공을 수행하기 위해서 필요한 접근공간을 제공한다. 흙막이 공법과 같이 가시설 공사의 안정성을 높이기 위해서는 가시설에 작용하는 외부영향요인을 찾고, 이에 대응하기 위한 설계기능을 구현해야 한다. 즉 외부영향요인이 가시설 성능에 가져오는 영향을 최소화하기 위한 설계요소와 설계요소의 수준을 찾아야 한다. 본 연구에서는 가설공사의 대표적인 공법인 흙막이 공법을 대상으로 가시설 설계시 고려해야 할 외부영향요인을 분석하고, 영향요소를 최소화하기 위한 내부영향요인으로써 설계기능의 개선방안을 제시한다. 설계기능 구현시에는 다구찌 기법을 적용하여 설계요소에 대한 체계적인 평가를 실시하여 가치향상을 분석했다. 적용사례에서는 외부영향요인의 영향을 가장 적게 받으면서 제품특성의 목표치에 가장 근접한 설계인자의 조건을 찾았다. 시범사례에서는 다구찌 기법을 적용하여 흙막이 설계기능을 구현함으로써 외부요인의 변화에 적절하게 대응할 수 있는 설계기능을 제공할 수 있다는 것을 보여줬다.

본 연구에서는 외단열 공사의 단열재 접착제 도포 품질을 자동으로 감리할 수 있는 모델을 제안하였다. 사례 적용 결과, 영역 분할 모델은 mAP 92.3%의 정확도를 나타냈고, 제안 모델의 접착제 면적 비율 산출 정확도는 98.8%, 접착제 덩어리 중심 간 거리 산출 정확도는 96.7%로 나타났다. 본 연구 결과는 외단열 공사의 감리를 위한 현장투입 인력을 최소화하면서 외단열 공사의 가장 빈번한 하자인 단열재 탈락 하자를 예방할 수 있으며 나아가 외단열 시스템의 활성화에 기여할 수 있을 것으로 판단된다. 향후에는 다양한 환경에서 외단열 공법의 시공 영상을 수집하여 영상 분할 모델의 성능을 높이고, 영상 내에 다수의 단열재가 포함된 경우에도 자동 감리할 수 있는 모델을 개발하고자 한다.

The objective of this study is to perform an analysis of the heat(heating and cooling) and lighting energy consumption according to the window area ratio and the application of horizontal louver, which is external shading device installed for the purpose of energy savings in office buildings. For this, a building was chosen as a typical example, and the heat and lighting energy consumption was calculated by using the daylight and building energy analysis simulation. The results showed that the total energy consumption, when the lighting control was applied, was reduced by an average of 11.49[%] compared to when there was no lighting control. The smaller the glazing ratio is, the less the total energy consumption is. Also, the application of the horizontal louver increases the total energy consumption under the same condition of glazing ratio.

The application of photovoltaics into building as integrated building components has been paid more attention worldwide. Photovoltaics or solar electric modules are solid state devices, directly converting solar radiation into electricity; the process does not require fuel and any moving parts, and produce no pollutants. So, the purpose of this research is to present how to get PVIB which can be applied building facade and how to apply it. From the basis of these results this study will intend to develop an integrated for optimal design of PV System.

System Identification is carried out for a full scale five-story builing to design a vibration controller. Dynamic characteristics such as natural frequencies, damping ratios, and modes are obtained from the input/output information by both sine-sweep method and white noise method. The active mass driver installed on the five floor is applied as external loading to move the building and each floor acceleration is measured and processed for the system identification. The identified building will be experimentally investigated again with viscoelastic dampers installed at inter-stories to obtain the response behavior. Corresponding result will be presented soon.

Today, educational facilities are considered to be one of the most important built environment. And the appropriate combinations and applications of technical elements related to green building on the education facilities are emphasized and demanded. These are must be compatible with the occupants' activities and their needs. The objective of this research is to identify and analyze of green building technologies, based on Green Educational Facilities' Case Study in Korea, USA, and Japan. As a result of the comparative analysis of this research, the green technological approaches, problem, and characteristics on educational facilities in different area, climate zone are identified and analyzed by external environment, energy, materials and resources, and indoor environment. It is useful as basic reference for future green educational facilities' planning and design in Korea.

Recently, to ensure the high openness and prospect right of the building, curtain wall system is mainly applied to the high-rise buildings at domestic and overseas. As a result, the use of Structural Sealant is increasing. Structural Glazing Sealant is applied with the glass and AL-FRAME (Mullion) that the strong structural strength is required to hold. However, the structural sealant at the construction site in a variety of external influences, such as wind load, thermal load, uv, chemical pollutants etc, in case of storing condition, if structural sealant stored in high temperature for a long period time, it will not perform well compared with initial performance. In this study, the influence of the performance of one-component structural sealant evaluated for proper storage conditions at the construction site and how to use the non-intended.

Mekuro-Kazoen BLDG. is complex of office, hotel, hotel, and banquet hall, built in 1991, Tokyo, Japan. This building suggest us various issue about the representation of traditionality in current architecture. We can find the possibility of representation of traditionality in large complex, in past, rarely applicated. Even in Japan, such trial in official building as New Office Building of Tokyo in Sinzuku shows a application only in the elevation plan. In Mekuro-Kazoen BLDG. the application of traditionality are fond not only in external appearance, but also in interior design. And the modernity and traditionality in this building are represented simultaneously not deterioating each other. the issues of representation of traditionality in interior design should be succeed not only in now but also in future. The method of application need to be studied and improved. The fields of application also should be extended such as large complex buildings and future-oriented buildings.
