  • 건축법 시행령 제36조에는 3층 이상의 건축물로 문화 및 집회시설 중 공연장이나 위락시설로 바닥면적이 1천 $m^2$ 이상인 건축물은 옥외피난계단을 설치하도록 하고 있다. 도시의 인구집중화와 함께 고층빌딩의 증가는 인적재난에 대한 다양한 대비책을 요구하고 있다. 최근 10년 동안 고층빌딩 증가율은 85%로 급등하였다. 이러한 고층빌딩의 증가는 도시지역의 인적재난으로 이어져 화재발생 시 많은 인명피해와 재산피해를 동반한다. 고층빌딩에서 화재가 발생하였을 때 가장 어려운 소방활동이 피난활동이다. 상층으로 확산되는 연기 때문에 고층빌딩에서의 피난로 확보는 인명피해를 최소화 시키는 유일한 방법이다. 고층빌딩에서 직통계단이나 옥내계단으로는 피난로 확보가 어려워 고층빌딩 일수록 옥외피난계단이 필요하다. 옥외피난계단 설치에 관한 현행 법규는 너무 미미(微微)하여 고층빌딩의 피난로 확보대책으로는 적당치 못하다. 고층빌딩의 피난로 확보를 위하여 고층빌딩군(群)의 분류에 해당되는 10층 이상의 건축물에는 옥외피난계단 설치를 의무화하도록 관련법을 개정토록 하여야 한다.

  • 철도 차량에서의 화재 발생 시 피난에서 차량에서 승강장이나 터널 같은 외부 환경은 매우 중요하다. 많은 인원이 탑승하게 되는 지하철과 그 승강장의 영향을 알아보기 위해, SIMULEX, PATHFINDER, STEPS를 시나리오에 적용 비교해 보았다. 대상차량은 서울에서 운행되는 차량을 기준으로 하였으며, 대상 승강장은 [도시철도 정거장 및 환승 편의시설 보완설계지침]을 기준으로 제작한 모델을 적용하였다.

  • Safety, livability, and efficiency are the three prominent problems of tall buildings, which are also the severe challenges to designers. We proposed the idea of building the sky town to solve these problems, which can be summarized in two sentences, one is tall building multi-storised, and another one is vertical facilities municipal-infrastructurised. The tall building can be horizontally cut into several multi-storey buildings by some large platforms. The platform extends a certain width to block the fire from spreading. Tall buildings are connected together as a group. One of them is a traffic core, which is used for vertical transportation and MEP. It connects to traffic center such as metro, while most of the other tall buildings' cores can be very much released, so as to achieve maximum efficiency of floor usable area and to give good traffic organization. By combining traffic core, platforms, and multi-storey buildings' inner traffic, a transportation network is formed. Finally, we refer to the design of Raffles City Chongqing to make a sketch of sky town.

  • The surveillance system for urban transit now adapt the newest IT technology. The Surveillance system analyzes the video information from various cameras intelligently and determines the critical status automatically. Other sensors, for example fire sensor and audio sensor are used in the surveillance system for increasing the correctness of surveillance. The surveillance system tries to increase the performance of surveillance by gathering lots of information for the current situation and analyzing them intelligently. IP-Based Integrated system needs the distributed computer system with location and functions. For correctly running this system, a distributed software is needed. In this paper, we study the distributed software for IP-based integrated surveillance system. The required functions, safety and extendability are suggested.

  • The rural area has aged and depressed for urban area in Korea. Furthermore, the rural house has deteriorated and is vulnerable to disaster which collapse, fire, landslide, and so on. For this matter, it need to an evaluated system for deteriorated level of rural house. The evaluated system has a repairing method and an estimated cost for rural house to offer native in rural area. This study could draw evaluation factor for deteriorated level of rural house as a basic study for the evaluated system. The evaluation factors is compared the Korean housing performance grade indication system, the Korean green building certification criteria, and the Japanese housing performance indication system. As a result, they could eight types. There are a mothproof, an waterproof, a finishing material, an asbestos cement slate of roofing, a mobility right, an opening and closing of doors and windows, an indoor environment.

  • Modern society is transforming into an extreme climate environment. This is fatal to humans and ecosystems and is expected to cause large-scale damage. As this spokesman, natural disasters are increasing as this global average temperature rises. Social and economic damage by this tendency is also increasing. In addition, the frequency and scale of social disasters are increasing. Damage to the living area due to the damage of the infrastructure due to the increased reliance on infrastructure has been increasingly enlarged. In this research, various disasters such as natural disasters and social disasters analyze the impact on urban safety. A local autonomous entity K Priority Management Establish a kind of disaster, prepare crisis management manual, and use it as a basic material of education / training.

  • 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.

  • It is of great importance to assess the residual displacement demand in the performance-based seismic design. In this paper, a hybrid deep learning model for predicting the residual displacement spectra under near-fault (NF) ground motions is proposed by combining the long short-term memory network (LSTM) and back-propagation (BP) network. The model is featured by its capacity of predicting the residual displacement spectrum under a given NF ground motion while considering the effects of structural parameters. To construct this model, 315 natural and artificial NF ground motions were employed to compute the residual displacement spectra through elastoplastic time history analysis considering different structural parameters. Based on the resulted dataset with a total of 9,450 samples, the proposed model was finally trained and tested. The results show that the proposed model has a satisfactory accuracy as well as a high efficiency in predicting residual displacement spectra under given NF ground motions while considering the impacts of structural parameters.

  • The seamless integration of the architecture and structure of a tall building plays a key role in establishing a recognizable and iconic design. The structural system developed for Shenzhen Rural Commercial Bank Headquarters (SRCBH) utilizes enhanced structural innovations unique to the tower's geometry to improve structural and sustainability performance. SRCBH utilizes a steel diagrid system pulled outside of the enclosure line with diaphragm forces resolved primarily by corner diagonal beams. During the design process the structural systems underwent performance based design and optimization for wind and seismic loading. Resiliency was prioritized for structural design as well as fire resistance. More closely integrating the structure of a building with its architecture and sustainability goals can lead to unique and innovative towers with a timeless expression.

  • The 53-meter tall Albizzia Tower is a white, mineral building with a mixed concrete and wood structure. It harmoniously interacts with the high rises of La Confluence. Its base is largely open, in direct relation to the public space. The spaces are mutable, reversible, moldable thanks to a streamlined structure: posts, beams in glued laminated wood, with posts pushed back on the facade to facilitate the layout of office and housing floors, CLT floors with a span of 7 meters.
