In this paper we discuss the terms "exo-spatial design," "solar carving," and "bridging" as strategies for creating more socially connective tall buildings. As a typology, high-rise residential buildings have a unique set of challenges to becoming fully activated urban participants in the cities in which they are located. While there is a general recognition and appreciation that tall buildings provide identity to a city, there is often criticism of how they relate to their surroundings. Critics have posited that tall buildings are insular and foreboding by their very nature. This paper explores several design avenues for architects to consider in order to improve the social aspect of tall buildings. As all cities become taller and denser to accommodate growth, the need to design social space in, on, and around tall buildings must be continually examined if we are to have cohesive urban fabric that supports communities.

Field measurements of the wind-induced response of two residential reinforced concrete buildings, among the tallest in the world, have been performed during two typhoons. Natural periods and damping values have been determined and compared with other field measurements and empirical predictors. Suitable and common empirical predictors of natural period and structural damping have been obtained that describe the trend of tall, reinforced concrete buildings whose structural vibrations have been measured in the collection of studies in Hong Kong compiled by the authors. This data is especially important as the amount of information known about the dynamic parameters of buildings of these heights is limited. Effects of the variation of the natural period and damping values on the alongwind response of a tall building for serviceability-level wind conditions have been profiled using the gust response factor approach. When using this approach on these two buildings, the often overestimated natural periods and structural damping values suggested by empirical predictors tended to offset each other. Gust response factors calculated using the natural periods and structural damping values measured in the field were smaller than if calculated using design-stage values.

본 논문에서는 국내의 초고층 주상복합건축물들에 대하여 층수와 높이 등의 규모 및 구조형식과 횡력저항 시스템의 유형 및 사용 재료의 강도와 층별 콘크리트 강도의 조닝 등에 대하여 조사 분석하여, 이를 토대로 초고층 주상복합 건축물의 구조 계획 유형을 분석하였다. 조사한 결과, 국내 초창기 초고층 주상복합 건축물의 구조시스템은 도곡동 타워팰리스와 같이 철골철근콘크리트구조(SRC)로 건설된 사례가 많았으나, 2005년 이후에는 대부분이 철근콘크리트(RC)구조로 건설되었다. 구조체에서 코어부분을 전단벽으로 배치하여 횡력저항 시스템으로 활용하고 있고, 콘크리트의 강도는 층수에 따라 고층부, 중간부, 저층부로 나누어 강도를 조닝하여 적용하고 있었다. 사례조사를 토대로 국내에 주상복합건축물의 대표적인 유형으로 건설되고 있는 40층 및 60층 규모의 건축물에 대한 구조계획 기초자료를 제시하였다.

This paper reflects on the structural design of Haut; a 21-storey high-end residential development in Amsterdam, the Netherlands. Construction started in 2019 and is in progress at the time of writing. Upon completion in 2021, Haut will be the first residential building in the Netherlands to achieve a 'BREEAM-outstanding' classification. The building will reach a height of 73 m, making it the highest timber structure in the Netherlands. It contains some 14.500 ㎡ of predominantly residential functions. It features a hybrid concrete-timber stability system and concrete-timber floor panels. This paper describes the concepts behind the structural design for Haut and will touch upon the main challenges that have arisen from the specific combination of characteristics of the project. The paper describes the design of the stability system and -floor system, the analysis of differential movements between concrete and timber structures and wind vibrations. The paper aims to show how the design team has met these specific challenges by implementing a holistic design approach and integrating market knowledge at an early stage of the design.

현재 주택시장은 주택증가율 상회와 미분양증가, 장기침체로 어려우나 주상복합은 복합화를 위주로 주거시설과 다양한 수요 시설을 조합할 수 있으며 초고층화하여 넓은 오픈스페이스와 우수한 조망을 확보하는 장점을 가진다. 그러나 스카이라인 형성 저해, 건축물의 높이에 의한 문제점이 야기된다. 이에 본 연구는 초고층 주상복합 건축물 입지유형에 따른 높이기준 및 세장비를 제안하는데 목적이 있다. 연구의 방법은 먼저 문헌조사를 통한 용어정리, 선행연구조사를 하고 사례조사로 서울시내의 16개의 사례를 중심으로 도시 계획적 차원과 건축물 단위의 높이와 관련한 사항을 조사하였다. 이를 기준으로 입지유형별 높이기준과 세장비를 제안하여 다음과 같은 결론을 가진다. 첫째, 도시계획적 차원에서 입지유형별 주상복합의 높이는 부도심을 중심으로 시작하여 높아지며, 150m이하에서 200m이상으로 제안이 가능하다. 둘째, 세장비는 초고층건축물과 달리 주상복합의 저층부의 면적이 크므로 1:3 이상으로 계획하여 시각통로를 두어 개방성 및 군(群)의 형성에 통일성 있게 계획한다. 셋째, 초고층 주상복합 건축물과 관련한 높이에 있어 특별건축구역제도 수정 및 초고층 관련 특별법을 제정한다.

The aim of this study is to understand the plan characteristics used in unit floor planning mainly with examples of mixed-use residential tall buildings. The study will extract plan characteristics mainly using the graph expressive technique with essential information of the zoning function of residential space, rather than merely analyzing the various construction floor plans by type. The research method involves studying a group of 50-story buildings (over 200 meters) which were built between 2002 and 2008. Among 6 high-rise residential buildings case, we extract the most preferred type from 34 types, And then we simply classify rooms in 3 zoning, the master, living and children's zones. Finally we analyze the correlation among 3 simple zone and then extract some model type. The results of this study revealed three main findings. First, using the 3 functional zones, the shape of the main building and the unit floor plan can be analyzed simply even when they appear to be complicated. Second, we can extract common features when we analyze the unit floor plan from the viewpoint of the penetrability among 3 zoning. Third, we can extract 2 types when we analyze the unit floor plan from the viewpoint of 3 connected functional zoning concepts.

The objective of optimization is to present a design process that minimizes the total material consumption while satisfying current codes and specifications. In the research an optimization formulation for RC shear wall structures is proposed. And based on conceptual design methodology, an optimization process is investigated. Then optimal design techniques and specific explanations are introduced for residential buildings with shear wall structure, especially for that with a rectangular layout. An example of 30-story building is presented to illustrate the effectiveness of the proposed optimal design process. Furthermore, the influence of aspect ratio on the concrete consumption and the steel consumption of the superstructure are analyzed for this typical RC shear wall structure; and their relations are obtained by regressive analysis. Finally, the optimal material consumption is suggested for the residential building with RC shear wall structure and with rectangular layout. The relation and the data suggested can be used for guiding the design of similar RC shear wall structures.

This research suggests the most effective way for improving energy efficiency in tall buildings is a "fabric-first" approach. This involves optimizing the performance of the building form and envelope as a first priority, with additional technologies a secondary consideration. The paper explores a specific fabric-first energy standard known as "Passivhaus". Buildings that meet this standard typically use 75% less heating and cooling. The results show tall buildings have an intrinsic advantage in achieving Passivhaus performance, as compared to low-rise buildings, due to their compact form, minimizing heat loss. This means high-rises can meet Passivhaus energy standards with double-glazing and moderate levels of insulation, as compared to other typologies where triple-glazing and super-insulation are commonplace. However, the author also suggests that designers need to develop strategies to minimize overheating in Passivhaus high-rises, and reduce the quantity of glazing typical in high-rise residential buildings, to improve their energy efficiency.

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.

Busan's Haeundae Resort project, which is currently being constructed by POSCO E&C, comprises the 101-story Landmark Tower and two 85-story residential towers. Presently, foundation and basement construction is complete, with a final completion date set for 2019. Considerations about the construction and design of the three reinforced concrete high-rise buildings will be discussed in this paper.
