최근 많은 나라에서 초고층 철근콘크리트 구조물의 등장과 더불어 저 층의 경우에도 구조물에 대한 유지보수가 많아지고 있다 실제로 많은 다양한 방법들로 만들어진 경우 가 많다. 고강도 콘크리트는 그것의 제조, 시공, 그리고 구조 설계 식이 다를 수 있기 때문에 매우 중요하게 다루어야 한다.(중략)

A new freeform structure representing "Diagrid, Cantilevered, Tilted." which has been considered not only its distinctive appearance but also the structural advantages becomes one of the trends in tall building design. Especially in the Diagrid system, loads can be distributed through bracing frame so that it can be save the materials since it has more effective in the structure behavior. But the seismic performance index such as response modification factor is not clearly defined yet. Even though the diagrid is supposed to show higher seismic performance, it is underestimated due to the lack of reliable data. In this paper the response modification factor for the diagrid system is experimentally explored.

The diagrid structure is now one of the trends in tall-building structures. It is preferred not only because of its distinctive appearance but also because of its structural advantages. There are few diagrid buildings that actually exist, however, because of the nodes, which are difficult to make and cost too much. In this study, a node-type diagrid building material with a more efficient structure but with fewer diagrid nodes, fabricated using the finite element method, was proposed and validated via experimentation.

건물이 초고층화됨에 따라 고강도 콘크리트를 구조물에 적용하고 있으며 내화 시 폭열 예방을 위해서 고강도 콘크리트에 섬유를 첨가하는 경우도 있다. 초고층 구조물 합성부재에서 강재보와 콘크리트 슬래브의 합성작용을 위해서는 전단스터드를 필요로 하게 된다. 오늘날 제시된 전단스터드 설계식은 일반강도 콘크리트 실험에 의해 제시되었고 전단스터드는 항복강도에만 제한되는 것으로 나타났다. 따라서 본 논문은 초고층 건물에 적합한 고강도콘크리트를 기존 제안식으로 비교 분석하고 새로운 설계식의 필요성을 확인하며 ANSYS 모델링을 통한 전단스터드의 거동을 분석하는데 그 목적이 있다.

The research intended to understand the lateral behavior in core and offset outrigger system. To achieve this goal, a structural analysis and design of 70 stories building was carried out by making use of MIDAS-Gen. And the primary parameters of this analysis were the stiffness of outrigger and the location of outrigger in plan. On the basis of the analysis results, we analyzed the lateral behavior of structural elements such as slab, outrigger and exterior columns in core and offset outrigger. In this analysis research, it is indicated that the stiffness of outrigger and the outrigger location in plan had an any impact on lateral behavior in outrigger system of tall building. Specially, slab stresses in core outrigger system were highly distributed in the slab near the outrigger system to connect shear walls and exterior columns while slab stresses in offset outrigger system were highly distributed in the slab between the outrigger system and shear walls. Also the study results can be of significant help to obtaining the engineering data for the reasonable structure design of the high-rise outrigger system.

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.

The problem controlling lateral drift by the wind and the earthquake is very important in high rise buildings. But, outrigger system, generally used for residential tall buildings in Korea, has weak points with the occupancy of special space, the difficult construction and the long duration of works. On the other hand, the damper reduces story drifts of building structure by absorbing vibration energy induced by the dynamic loads and the application of damper systems is relatively simple. Also, the lateral drift control system such as outrigger system may raise the wind vibration problem of serviceability like human comfort and this problem may need another vibration control devices. Accordingly, we analyze the effect of the drift control using various dampers to substitute for outrigger system as the efficient system in residential tall buildings.

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.
