  • Seismic analyses of structures can`t be performed without considering the effect of soil-structure interaction and seismic responses of a structure taking into account the stiffnesses of a foundation-soil system show a significant difference from those with a rigid base. However, current seismic analyses of apartment building structures were carried out assuming a rigid base and ignoring the characteristics of a foundation and the properties of the underlying soil. In this study, seismic analyses of apartment buildings of a particular wall-slab structural type were carried out comparing seismic response spectra of a flexible base with those of a rigid base and UBC-97. Wall-slab type low-rise or mid-height apartment buildings built on the deep soil layer showed a rigid body motion with the reduced seismic responses due to the base isolation effect, indicating that it is too safe but uneconomical to utilize the design spectra of UBC-97 for the seismic analysis of a wall-slab type apartment buildings due to the too conservative design.

  • The ASHRAE Design Guide for Tall, Supertall and Megatall Building Systems was produced in collaboration with the CTBUH. The design guide outlines various tall building mechanical systems that are presently being designed or are planned for the future. Tall commercial buildings in particular present a series of design problems that set them apart from other functions. The Design Guide will be of interest to owners, architects, structural engineers, mechanical engineers, electrical engineers and other specialized engineers and consultants. This design guide addresses design issues for tall commercial buildings, which are very often mixed-use, and commonly consist of low level retail, office floors, residential units, and hotel uses.

  • The purpose of this study is to find the characteristics of planning factors to the outdoor space of the olympic village munchen. The result of the research are follows; 1) The horizontal gardens of the low buildings and hanging gardens on the terraces of the high-rise buildings are intended as a continuation of the concept of the modelled landscape. 2) By virtue of the choice of the type of building and the way in which the buildings are staggered, the residents have an unimpaired view of the green spaces and recreation areas. 3) Leisure value is further enhanced by the proximity of the residential arms to the footpath running north to south. 4) The terraces allow the residents to enjoy more sun and sky, so that the view into the distance is the rule. 5) To improve orientation, the pedestrian paths to the residential wings are also situated directly over the underground vehicle-access roads.

  • Part 1에서 제안한 평가표를 이용하여 순수 골조로만 이루어진 철근콘크리트 건물과 골조와 전단벽이 혼합된 철근콘크리트 건물의 내진성능을 각각 평가하였다. 본 평가법은 효율적이며 비교적 간단하게 건물의 내진성능평가가 가능하며, 내진성능 평가점수를 토대로 어떤 특정 지진강도에 대한 건물의 구조손상정도를 평가할 수 있다는 장점을 가지고 있는 것이 큰 특징이다.

  • Soft or extreme soft storeys in multi-storied buildings cause localized damage (and even collapse) during strong earthquake shaking. The presence of such soft or extremely soft storey is identified through provisions of vertical stiffness irregularity in seismic design codes. Identification of the irregularity in a building requires estimation of lateral translational stiffness of each storey. Estimation of lateral translational stiffness can be an arduous task. A simple procedure is presented to estimate storey stiffness using only properties of fundamental lateral translational mode of oscillation (namely natural period and associated mode shape), which are readily available to designers at the end of analysis stage. In addition, simplified analytical expressions are provided towards identifying stiffness irregularity. Results of linear elastic time-history analyses indicate that the proposed procedure captures the irregularity in storey stiffness in both low- and mid-rise buildings.

  • The 2020 National Building Code of Canada (NBC) and the 2021 International Building Code (IBC) both include Tall Wood Buildings (TWB) and are hailed as documents responsible for the proliferation of Mass Timber construction. Mass Timber construction is critical to reducing the carbon footprint of the construction industry; a sector acknowledged as being one of the greatest contributors of global annual CO2 emissions. Origine, a 13-storey multi-residential building erected in 2017 in a previously unsuitable site, is currently the tallest all-wood building in North America. This article describes the challenges overcome by the designers and client as they engaged with code officials, building authorities, and fire-service representatives to demonstrate the life-safety performance of this innovative building. It also traces the development of the "Guide for Mass Timber Buildings of up to 12 Storeys" published in Quebec and how it has enabled other significant Tall Wood projects across North America.

  • Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

  • In urban regeneration, resident participation and respect of residents' need have become a major important issue. The purpose of this study is to identify residential area improvement characteristics expected by local residents. Data used for this study were collected from survey which used questionnaire and village image map construction tool kit, developed for facilitating the residents' participation in an actual housing improvement area at Kwngjoo, Korea. The major contents surveyed through questionnaire were first, future images of the area second, directions of improvement third, preferred architectural types such as high or low rise buildings. and a total of 335 data was collected within 4 days during 12-14 December, 2008. The kit was used by parents of students at a local elementary school, and 205 image maps were collected. Content analysis was to analyse characteristics of villages shown in the constructed image maps. Lynch's five elements were utilized to select areas for analysis. As a result, types of buildings desired by residents at the selected four local areas were identified. In general, residents desired their village to be improved with low and mid rise buildings, respecting existing cultural assets. This study showed that there is certain characteristics in relation to the selected areas. Besides, the tool kit used this study showed the effectiveness in collecting opinions from young households in the improvement area within a short time. The tool is expected to be useful in attracting residents and in facilitating participation of wide range of local residents by improving the constraints stemming from time and space.

  • 지진 발생 시 방송통신서비스는 현장 구조 및 효과적인 복구 작업에 직결된다. 최근에 다양한 면진장치들이 방송통신설비의 심각한 피해를 방지하기 위하여 건물 층과 방송통신설비의 바닥부 사이에 설치하는 방법이 널리 사용되고 있다. 하지만 긴 고유주기를 가진 건물은 공진현상에 따른 예상치 못한 응답증폭으로 인하여 더 큰 피해가 발생할 수도 있다. 따라서 본 연구에서는 두 개의 면진장치를 선정 후 중층, 고층건물의 해석적, 실험적 연구를 통하여 면진장치가 바닥부에 설치된 방송통신설비의 내진 안전성을 평가를 목표로 한다. 해석적 연구를 수행하여 가진 시 중층, 고층건물 최고층의 저주파수 영역대의 동적응답을 확인하였다. 또한 해석적 연구에서 확보한 층응답을 바닥부에 면진장치가 설치된 방송통신 설비를구비하여 실증 실험을 통해 내진안정성을 평가하였다.
