The purpose of this paper is to search the optimal location of offset outrigger system in high-rise building after a structural schematic design of 80 stories building was conducted, making use of MIDAS-Gen. In this research, the key factors of analysis study were column stiffness, outrigger position in plan and outrigger location in height. For the aim of finding out the optimum position of offset outrigger system in tall building, we studied the lateral displacement in top floor which is the very essential variables in the structural design of high-rise building. The results of study showed that the column stiffness, the outrigger location in plan and outrigger location in height had an effect on the optimal position of outrigger system. Also, it is indicated that the research results can be useful in acquiring the structural design materials for seeking the optimum position of offset outrigger system in tall building.

최근 국내 대도시를 중심으로 초고층건축물이 계획 건립되고 있으며, 그에 따라 국내 외적으로 초고층건축물 화재가 빈번하게 발생하고 있으나, 현재 국내 소방기술은 그에 대한 어떤 확실한 대안도 갖고 있지 못하다. 2010년 발생한 부산 해운대 우신골든스위트 화재사례를 통해 고층건물 화재진압의 부진했던 주된 원인과 문제점이 분석되면서, 최근 국내 고층건축물의 화재를 대비한 관련법(건축법, 소방법 등)들이 제정되고 있다. 그러나 아직도 고층건축물에서의 화재진압방법, 인명구조 및 소방진압장비의 연구 개발의 성과가 부족하다. 본 연구에서는 초고층건축물의 외장재를 통한 수직화재 확산방지를 위한 보다 효과적인 진압방법과 인명구조방법을 제안하고자 한다.

This study purposed to investigate the optimal outrigger location in tall building with cap truss after a structural schematic design of 80 stories building was performed by using MIDAS-Gen. In this paper, the main parameters of structural analysis were the outrigger location and stiffness of main structural elements (outrigger, exterior column, shear wall etc). In order to search the optimal outrigger position in high-rise building with cap truss, we analysed and examined the lateral displacement of top floor which is one of the very important considering factors of tall building structural design. The paper results indicated that the outrigger location and the stiffness of main structural elements such as outrigger, exterior column and shear wall had an effect on the optimal outrigger location. And it is verified that the study results provided the basic engineering data for fixing the most optimal outrigger location for minimizing the lateral displacement of tall building.

본 연구에서는 세계 각지의 초고층 건축물 사례 55개를 대상으로 초고층 형상의 비정형성을 대표적 유형에 따라 분류하고 해당 유형에 적용된 구조시스템을 조사함으로써 건축물의 비정형 형상과 이를 구현하기 위해 적용된 구조시스템간의 상관관계를 분석하였다. 대표적인 비정형 형상을 5개 유형으로 분류하고 구조시스템의 적용빈도를 조사한 결과, 적용 사례가 많은 Extrusions와 Tapers 형태에서는 적용된 구조시스템과의 유의미한 상관관계를 파악할 수 있었으며, 적용 사례가 많지 않은 Twisters, Tilted, Free Form 형태에서는 구조시스템의 상대적 적용 경향을 파악할 수 있었다. 본 연구의 결과는 비정형 형상에 적합한 구조시스템 대안의 우선순위를 설정하고 구조시스템 생성을 위해 형상으로부터 추출해내야 할 초기 파라미터를 선정하는데 활용할 수 있을 것으로 기대된다.

Most of the previous seismic analyses have been carried out by separating the ground and structures, and there is a lack of comparative study on the dynamic behavior of high-rise and low-rise buildings. Therefore, in this study, the sensitivity analysis was performed with selected parameters by using a finite element analysis program in order to grasp the dynamic behavior of high-rise and low-rise buildings. As a result, it was turned out that the horizontal displacement, the interstory drift ratio, and the bending stress of a high-rise building were more affected by a long seismic wave than a low-rise buildings. Also, the weak parts of a high-rise and low-rise building were more affected by type of seismic wave than the ground conditions. Therefore, it is inferred that it will be helpful for seismic designs to consider the influence of ground conditions and seismic wave type on buildings.

Recently, building structures tend to be super high-rise and large-scale with the development of concrete technology. When high-rise building is constructed of reinforced concrete structure, it has a disadvantage that its own weight increases. Light weight aggregate(LWA) was developed to compensate for these shortcomings. Manufacturing concrete using these light weight aggregates has the advantage of reducing the self weight of the reinforced concrete structure, but has a disadvantage in that the strength of the concrete is reduced. In this study, an experimental study was conducted to investigate the strength characteristics of hardened cement according to the presence or absence of surface coating of lightweight aggregates. As a result, in terms of compressive strength, the surface-coated lightweight aggregate exhibited higher strength than the uncoated lightweight aggregate. Also, it was considered that this is because the interfacial voids of the surface coated lightweight aggregate mixed cement hardened body were filled with blast furnace slag fine powder particles.

고층화의 최대 장점은 과밀한 수평 밀집 환경을 건축물의 수직적 확장으로 과밀 현상에서 다층 보행자 시스템으로 대지의 공지를 활용하는데 있다. 이러한 초고층 건물은 특성상 건물의 강도, 강성, 안전성 등을 고려하여 설계가 이루어졌고, 이러한 특성으로 인해 비교적 건물 내의 대공간 확보와 평면의 자유를 얻기 힘들었다. 그래서, 이런 단점을 보완하기 위해서 그 대안으로 SAC조와 현수교 구조(Cable)를 제안하고자 한다.
