Formwork accounts for a large proportion of the framework in high-rise construction projects in terms of the duration and cost. Especially, slab formwork has a significant influence on these factors. However, the current selection of formwork method in general contractors depends on the decisions of few experienced engineers, and layout planning of the formwork in specialty contractors requires lots of time by different floor types. As a preliminary study for developing an optimum layout model in slab formwork of high-rise building construction, this study proposes the process of the optimum layout model and determines a fitness function for use of the genetic algorithm aimed at table formwork.

The principle of energy dissipation technology is to dissipate or absorb the seismic energy input through the deformation or velocity change of dampers installed in the main structure of high-rise buildings, so as to reduce the seismic response of the buildings. With the development of energy dissipation technology, recognized as an effective and new measurement for reducing seismic effects, its application in high-rise buildings has become more and more popular. The appropriate energy dissipation devices suitable for high-rise buildings are introduced in this paper. The effectiveness of energy-dissipation technology for reducing the seismic response of high-rise buildings with various structural forms is demonstrated with a number of actual examples of high-rise buildings equipped with various energy dissipation devices.

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.

With the advent of cutting-edge technology, renewable energy is significantly considered as alternative resources to supply electric power. However, many barriers such as energy intermittency, high initial installation cost, and low-efficiency generation challenged building new infrastructure with clean energy. Efforts reducing greenhouse gas emissions and reliance on fossil fuels resulted in the decentralization of power generation like distributed energy resource (DER). This paper is to introduce and evaluate the feasibility of building-integrated photovoltaics (BIPV) in a high-rise building in Ulsan. To optimize BIPV, a variety of methods to minimize efficiency decrease and maximize electric power generation after installing BIPV on the building's facade are suggested. The variables causing power losses are analyzed. By utilizing System Advisor Model (SAM), actual power generated from solar panels is measured by Thin-film PV, Mono-crystalline PV, and Poly-crystalline PV.

For more than 100 years, American skyscrapers got along with the change of Modern architecture. However, high-rise building can not be regarded anymore as a monopoly of America. The purpose of this study is to clarify the aesthetic characteristics of Asian high-rise buildings. Basic concepts on the aesthetic and artistic expression of high-rise building have been discussed, emphasizing the importance of artistic characteristic. A brief introduction on the rise of Asian high-rise buildings also summarized in terms of changing trends for decades from 1970s. Among the 75 buildings in Asian countries out of 100 tallest buildings in the world, 10 buildings are selected to clarify the artistic characteristics which can be presented as an Asian trend in 21st century. The results can be summarized as follows; It was from 1990s that the Asian high-rise buildings began to express a specific regional aesthetics as a trend of post-modernism. Conventional ideas, traditional objects, and regional shapes and patterns are good instruments to successfully represent their national prides. Religions in Chinese and Islamic culture are popular motifs in Asian countries as well as feng shui and conventional idea of five primary elements. Traditional objects like pagoda and minaret are good precedents that can provide friendly recognized vertical objects. Many other interesting cases can be found referring to the traditional shapes and patterns like Chinese character, geometric pattern, Islamic sign, etc.

CPR in High-rise building is one of the challenging tasks to 119 paramedics, evacuating patient from the narrow and vertical area. This study was built to compare the method of mechanical CPR and manual CPR is to maximizing on-scene treatment time, and minimizing the hand-off time in cardiac arrest, transporting patient as fast as possible. The electronic data research (Science, Pubmed, Medline, Medline and 55 academic DB interworking) was conducted, and five articles were included by reviewing and excluding through the Covidence program and Review Manager version 5.4(Cochrane Collaboration). OHCA occurring on the higher floor indicates lower in survival. A total studies uniformly reported mechanical CPR is more effective during the high-rise building evacuation, than manual CPR in rate, depth, and hands-on time of chest compression. Use of mechanical CPR device is more suitable in case of High-rise building OHCA to improve the survival rate which is affected by high-quality CPR.

It is usual to evaluate the performance of the cool roof by measuring in-site rooftop temperature using thermal infra-red camera. The principal advantage of rooftop thermal infrared image acquired in oblique vantage point of super high-rise building as a remote sensor is to provide, in a cost-effective manner, area-wide information required for a scattered rooftop target with different colors, utilizing wide view angle and multi-temporal data coverage. This research idea was formulated by incorporating the concept of traditional remote sensing into rooftop temperature monitoring. Correlations between infrared image of super high-rise building and in-situ data were investigated to compare rooftop surface temperature for a total of four different rooftop locations. The results of the correlations analyses indicate that the rooftop surface temperature by the infrared images of super high-rise building alone could be explained yielding $R^2$ values of 0.951. The visible permanent record of the oblique thermal infra-red image was quite useful in better understanding the nature and extent of rooftop color that occurs in sampling points. This thermal infrared image acquired in oblique vantage point of super high-rise made it possible to identify area wide patterns of rooftop temperature change subject to many different colors, which cannot be acquired by traditional in-site field sampling. The infrared image of super high-rise building breaks down the usual concept of field sampling established as a conventional cool roof performance evaluation technique.

When seismic isolation system is applied to high aspect-ratio (height/wide-ratio) steel structures, there are several problems to be taken into consideration. One is lifting up tensile force on the isolation bearing by overturning moment caused by earthquake. Another is securing building stiffness to produce seismic isolation effects. Under these conditions, this paper reports the structural design of high-rise research building in the campus of Tokyo Institute of Technology. With the stepping-up system for the corner bearings, the narrow sides of single span framework are designed to concentrate the dead load as counter-weight for the tensile reaction under earthquake. Also we adopted concrete in-filled steel column and Mega-Bracing system covering four layers on north & south framework to secure the horizontal stiffness of the building.

Openness to outside is one of the most critical advantages for high-rise buildings. However, the effect of openness can be decreased if it is blocked by other high-rise buildings, especially built within the building complex of commercial district. The purpose of this study is to identify the horizontal openness of high-rise residential buildings by comparing 3 different cases of building arrangement type. A new method of evaluation has been introduced on the basis of distance to measure the openness including the matter of securing privacy. As a result of this study, comparative analysis was possible and relatively plentiful results of analysis could be drawn out. Through the process of analysis, this study set the evaluation indicators suitable to the analysis of openness of unit households. Thereby, the results of this study are expected to be used as useful basic data in planning high-rise mixed-use buildings.
