  • This study had the goal of analyzing the economic feasibility and constructability of a fire resistant curtain wall system using Light-weight Inorganic Composite Foam Board(LI-CFB). LI-CFBs, new materials with excellent fire resistance are being developed for use as the back panel of curtain wall and their fire resistance has already been analyzed through actual tests in earlier studies. In this study, a mock-up test involving the installation of the fire resistant curtain wall system on an actual building was conducted, and the system was compared with a common curtain wall system. This system is applied in the same way as a common curtain wall system. But the cutting LI-CFBs, which are brought from a factory, are used in the system and attached on the frame (mullion and transom). Even though the system requires more working time than the existing system, the LI-CFBs back panels are easy to cut and do not produce dust. Also, the panels are able to be assured the quality by checking damaged parts easily. Besides having a high level of fire resistance, the system's economic feasibility and constructability meets or exceeds those of the existing system.

  • The purpose of this study was to develop the curtain-wall structure design evaluation manual that can easily examine the curtain-wall structural members (Mullion and Transom) stability from the position of the construction managers. Through analyzing the structural design reports in the previous studies and interview with industry experts, the curtain-wall structural member design process was elicited. The manual, which consists of Microsoft Excel-based work sheet and its manual, was applied to a real curtain-wall design project to make sure its usability. A workshop with three curtain-wall experts and three construction managers was conducted to identify pros and cons of the manual, thereby enhancing its applicability in the future.

  • Recently, the buildings have been likely to shape Super Tall trend. Therefore, the exterior parts of the buildings come to be changed. Instead of early heavy wall structure, it is changed to light wall concept of curtain wall system. However, the curtain wall system causes lots of loads due to the external surrounding factors of building. In particular, due to the densely built-up condition in Korea, the generation of dew condensation is getting severer Since there has been no standardized process that reviews this generation of dew condensation, it is very urgent for us to prepare the reviewing process for the dew condensation for construction business managers. The purpose of this study is to assess dew condensation function of the curtain wall and provide the basic data for the provision of the future dew condensation review process by comparing and analyzing the range of generation of dew condensation as well as temperature distribution according to the change of relative humidity at the identical temperature by selecting the Unitized system and Stick system which are the representative types of curtain wall system.

  • 고층 건축물에 주로 사용되는 커튼월의 경우 구조체와의 접합으로 인해 층간 틈새가 발생하게 되고 이는 화재 시 틈새를 통해 화염이나 연기 등의 확산 경로가 될 수 있다. 본 연구에서는 커튼월 시스템에 적용되는 선형조인트 내화충전시스템의 개발을 위해 경제적이고 시공이 간편한 박스형 시스템을 도입하고 내부에 다양한 변경하여 내화성능을 평가하였으며, 그 결과 케이싱 내부의 단열재 20mm두께의 내화 뿜칠재와 석고보드를 케이싱 안쪽에 박스 형태로 구성한 시스템이 가장 안정적이고 온도상승도 작은 것으로 나타났다.

  • The curtain wall engineering of local high-rise buildings consists of many phases such as design, curtain wail design, manufacture, procurement, construction and facility management, each of which also involves many' actors such as architect, curtain wall consultants, manufacturers, contractors, and facility managers. Moreover, the method for controlling the C/W process of each participant is needed. Eliminating wastes and problems existed in the C/W process can be more effective. What is more, it is necessary to improve the efficiency of the current process and to strengthen the competence through application of SCM to the C/W life-cycle. In addition, it is important that a ]ot of information transfer smoothly and share through information system. Therefore, this study aimed to propose the scope of application and the improvement directions in applying Supply Chain Management concept.

  • Cost, schedule, quality are the essential parts of success of every construction project. It is especially true in high-rise building construction. Among the construction components in high-rise building construction, curtain walls are very important elements for the project success because they take large portion of cost and schedule. However, curtain wall construction process are very complicated, where many entities including designers, suppliers, contractors and even maintenance contractors are involved. Therefore, control and management of their relationships and production process are critical. It is suggested that this can be solved by the concept of Supply Chain Management which is supported by the automated information technology with Radio Frequency Identification. Such concept is defined as 'Automated Life-Cycle Management System Based On SCM' and this study suggests rode map to establish the system.

  • This study was to solve the lift problem of the existing unit curtain wall type by using the vertical material mullion as a rail in curtain wall, which is recently used as an external finishing material for high-rise buildings. It has been shown that the application of the curtain wall mullion's rail can be quantified even at 20m/sec wind speed through the Mock-Up test. Based on the sites selected for comparison of construction methods, it was analyzed that the construction period could be shortened by 48 days, or about 20 percent. It was analyzed that the number of construction workers could be reduced by about 33 percent from the previous nine to six. Based on these results, assuming the installation of curtain wall units of 10,000㎡, it is judged that construction cost can be reduced by 80% or more.

  • Due to the following reasons, the management of curtain wall parts and material is very Important. Firstly, curtain wall work is one of the main works in High-rise building construction for it takes about $10{\sim}15%$ of the total construction cost. Secondly, the whole process of curtain wall work including manu acture, delivery, storage, installation and maintenance is very complicated and sometimes more than 30 companies involve in the process. Thus there are many control points for curtain wall units. Thirdly, there are not enough space on site for material storage and this situation is more serious for sites in urban area. The purpose of this research is to validate an information systems using RFID technology that is developed to manage the curtain wall units following the process of curtain wall work. For the validation, the cycle times of curtain wall work before and a ter the system was used. The results show that using the systems shorten the cycle time of the curtain wall work. Thus it is concluded that the system can increase the efficiency of managing curtain wall work.
