최근 산업 발전과 더불어 대공간 건축물의 수요가 급증하고 있다. 이 분야 선진 기술은 지간 300m 이상의 대공간 건축물 실현도 가능하게 하고 있다. 대공간 구조에는 쉘구조, 스페이스 프레임 구조, 막구조, 케이블구조 등이 있다. 대공간 건축물은 기둥 없이 넓은 공간을 확보해야 하는 구조적 특성 때문에 설계초기 단계에서부터 시공문제를 병행하여 검토할 필요가 있다. 대공간 건축물 시공에 있어서 erection 공법은 공사비용, 공사기간 그리고 안전성 등에 큰 영향을 주는 것으로 알려져 있다. 대공간 건축물 erection 공법은 현장 여건 및 제반 조건에 따라서 그 수를 헤아릴 수 없을 정도로 많고 다양하지만, 대표적인 공법으로는 Element 방식, Block 방식, Sliding 방식, Lift-up 방식 그리고 복합방식 등이 있다. 본 연구에서는 기존 대공간 건축물을 대상으로 시공당시 적용한 erection공법을 조사하여 이것을 규모별, span별, 층고별, 구조형식별로 분석 및 검토하여 향후 대공간 건축물의 효율적 erection 공법 개발을 위한 기초 자료를 제공하는데 그 목적이 있다. Recently, the demand of the large span structures has been increasing. The large span structures include such a large scaled structures such as: the shell structure, the space frame structure, the membrane structure and the cable structure, etc. The large span structures are supposed to be confirmed and issued carefully at the initial process of the design besides the construction engineering aspects because of the structural specific cause that should solve and accomodate those large and wide space without columns. In the field of the large span structure construction, the erection construction method has been regarded as a major affected aspects on the construction cost, construction term, and stability. In the field of the large span structure construction, there are various construction method and system could be applied depends on the condition of the construction site and other circumstances such a major construction method as: the element method, the block method, the sliding method, the lift-up method and complexed method, etc. In this study, as the case study of the erection construction method of the large span structures, after survey and study that those existing large span structures construction cases which had applied and adopted the election construction method and analysis and classify into the Uoups by the size, span, ceiling height, structural system in odor to supply and suggest the data for the enhancement and development in the field of the erection construction method as a efficient structural solution of the large span structure construction.

This paper presents the result of condensation and mold growth risk in two trouble spots in an apartment building. The selected apartment unit (size of 112㎡) is located in city center with severe winter. The comer walls in an extended balcony and a dress room exposed to outside are recognized as problem spots for condensation and mold infestation in the apartment building over years. This study analyses mold risks based on a mixed simulation approach with additional mechanisms of the mold phenomenon and an aggregation method to arrive at quantified mold growth risk. This mold risk indicator (MRI) approach is applied to the selected trouble spots for quantitative condensation and mold growth risks. This study reveals that humidity control is required to avoid condensation and mold risk in the trouble spots in an apartment building.

The paper presents the results of mold growth risks in a comer wall near an entrance door in an apartment building. The coner wall is recognized as a problem spot for condensation and mold risks in apartment buildings. This study analyses mold risks based on a mixed simulation approach. This approach requires a reliable aggregation method to arrive at quantified mold growth risk and extension of standard simulation capacity to account for additional mechanisms of the mold phenomenon. The application of the developed mold risk indicator(MRI) is reported in apartment building case studies located in KOREA. This study reveals that 0.9 of temperature factor is required to avoid condensation and mold risk in the comer wall near an entrance door.
