The box system, composed only of reinforced concrete walls and slabs, are adopted by many high-rise apartment buildings recently constructed in Korea. In the buildings, one or more relatively large openings are cut in a shear wall for functional reasons. The openings influence the internal stress of the shear wall and also the structural behavior. Therefore, it is necessary to use subdivided plate elements for accurate analysis of the box system with openings. But it would cost tremendous amount of analysis time and computer memory if the shear wall is subdivided into a finer mesh in the analysis of high-rise buildings. So, it is difficult to apply this modeling method to practical procedure. In this study, an efficient method is proposed for the efficient and accurate analysis of shear wall with openings. The proposed method used the super element and matrix condensations, fictitious beam technique.

Recently, the high-rise apartment housings have become a prototype of the urban residential dwelling in Korea and the numbers of one have steadily been increasing. According to this trend, the strength of the construction materials is also fortified to assure the stability and durability of the buildings. Specially, Re-bar of SD500 type is largely used at the construction sites of high-rise building. This study analyzes the current usage of SD500 high-strength re-bar at domestic construction sites. Through the result of this analysis, we develop Economic Evaluation Model that measure economic efficiency of lap splice and coupler splice, which are most commonly used in connection SD500. The evaluation method was applied to construction sites in Seoul in December 2006, and the result revealed that coupler splice is relatively superior in terms of cost efficiency when the re-bar diameter is longer and the concrete strength is lower.

A sustainable building must produce an interior environment that is safe, healthy, comfortable and supportive of human performance and well-being. The medical human comfort: performance and productivity cost of unhealthy environment may cause much cost for healing. Research that buildings with daylight, fresh air, eco-materials and sustainable interior design are consistently rated as more comfortable and occupants performance, satisfaction and health. This study is to categorize systematically interior environmental design elements for improving sustainability with a view to developing an evaluation model of super high-rise apartment unit plans. With a literature survey and design guide lines concerning sustainable design elements, three hierarchical categorization levels of human, environment, energy and resources systems that consists of upper, middle, low design elements have been proposed. A total of 6 items have been suggested for middle level of categorization and 24 items for lower level. Finally a total of 107 design elements concerning the 24 items and their relationahips have been revealed. The needs for a systematic approach to interior environmental design for sustainability have been discussed.

The box system that is composed only of reinforced concrete walls and slabs are adopted on many high-rise apartment buildings recently constructed in Korea. And the framed structure with shear wall core that can effectively resist horizontal forces is frequently adopted for the structural system for high-rise building structures. In these structures, a shear wall may have one or more openings for functional reasons. It is necessary to use subdivided finite elements for accurate analysis of the shear wall with openings. But it would take tremendous amount of computational time and memory if the entire building structure is subdivided into a finer mesh . An efficient analysis method that can be used regardless of the number, size and location of openings is proposed in this study, The analysis method uses super element, substructure, matrix condensation technique and fictitious beam technique. Three-dimensional analyses of the box system and the framed structure with shear wall core having various types of openings were performed to verify the efficiency of the proposed method. It was confirmed that the proposed method have outstanding accuracy with drastically reduced time and computer memory from the analyses of example structures.

(초)고층건축물에서 승강로가 연기 확산의 주요 통로였기 때문에 승강기를 통해 피난하는 것은 권장되지 않았다. 하지만 북미에서는 승강로를 연기로부터 방호하기 위해, 승강로를 가압하는 방식을 사용하여 왔다. 이번 시험은 실제로 승강로 급기가압 방식을 이용해서 연기 전파를 차단할 수 있는지와 피난수단으로 승강기를 사용할 수 있는지를 검증하기 위해 고층 아파트에서 실시되었다. 시험 결과 승강로가압은 공기의 이동에 의한 마찰손실이 작았기 때문에 150 CMM의 풍량에서 승강장과 세대 사이에 50 Pa의 차압을 전층에 고르게 형성시켰다. 또한 1개층 세대 문과 승강기 문이 동시에 개방되었을 때, 180 CMM의 풍량으로 연기의 역류를 차단할 수 있는 방연풍속을 형성하였다. 그리고 승강로가압은 모든 문이 닫힌 상태에서 차압유지에 필요한 풍량과 1개층이 개방되었을 때 방연풍속을 유지하는데 필요한 풍량의 차가 작아서 과압의 우려가 낮을 것으로 예상되었다. 따라서 이번 시험을 통해 고층아파트의 화재 시에 승강로가압을 적용하면 일반인과 피난약자의 피난수단으로 승강기를 사용할 수 있음을 확인하였다.
