A high-rise Mixed-use building is a multi-purpose which has commercial, business and residential uses. In Korea, after the middle of 1990's, the rate of residential parts was Increased to 90%. Now, the residential parts finally bacame mainly. And residental spaces are more important than before. Residential spaces are according to variety trends such in their areas. Some companies have several interior design trend in their building. They sometimes use the interior trend when to sell their goods(apartments) in their macketing. Modern design is presented in almost dwelling-units-types. But Classic type is presented in large-units-types. Minimal design is presented in only some middle-units-type as well as in the cases of the companies having definite interior trend. Interior design trend is one another factor in dwelling spaces design.

Consider about aggregate's price, coarse aggregates from 13 to 25mm were widely used in ready mixed concrete company. But if only use 13 to 25mm aggregates in the concrete, gap grading problem would be occurred. When recycled aggregates from 13 to 25mm was used, continuous grading would increase the durability and strength for the concrete, meanwhile the construction waste materials would also be reused. In this paper, 5-13mm recycled aggregates was utilized, to analyse the fundamental properties for concrete, strength has been tested to evaluate the quality and reusing effect of the recycled materials.

Tall buildings which began from about 40 m tall office towers in the late $19^{th}$ century have evolved into mixed-use megatall towers over 800 m. It is expected that even mile-high towers will soon no longer be a dream. Structural systems have always been one of the most fundamental technologies for the dramatic developments of tall buildings. This paper presents structural systems employed for the world's tallest buildings of different periods since the emergence of supertall buildings in the early 1930s. Further, structural systems used for today's extremely tall buildings over 500 m, such as core-outrigger, braced mega-tube, mixed, and buttressed core systems, are reviewed and their performances are studied. Finally, this paper investigates the potential of superframed conjoined towers as a viable structural and architectural solution for mile-high and even taller towers in the future.

This study uses recycled green building materials based on a Taiwan-made recycled mineral admixture (including fly ash, slag, glass sand and rubber powder) as replacements for fine aggregates in concrete and tests the properties of the resulting mixtures. Fine aggregate contents of 5% and 10% were replaced by waste LCD glass sand and waste tire rubber powder, respectively. According to ACI concrete-mixture design, the above materials were mixed into lightweight aggregate concrete at a constant water-to-binder ratio (W/B = 0.4). Hardening (mechanical), non-destructive and durability tests were then performed at curing ages of 7, 28, 56 and 91 days and the engineering properties were studied. The results of these experiments showed that, although they vary with the type of recycling green building material added, the slumps of these admixtures meet design requirements. Lightweight aggregate yields better hardened properties than normal-weight concrete, indicating that green building materials can be successfully applied in lightweight aggregate concrete, enabling an increase in the use of green building materials, the improved utilization of waste resources, and environmental protection. In addition to representing an important part of a "sustainable cycle of development", green building materials represent a beneficial reutilization of waste resources.

본 연구는 복합용도건축물 내에 공공도서관을 건립하는 것이 효율적인 공공도서관 인프라 확충 방안의 하나로 인식하였다. 서울에 있는 112개 모든 공립 공공도서관을 대상으로 도서관의 복합화 여부를 현장방문과 전화문의를 통해 조사하였다. 조사 결과 전체 도서관의 약 50%에 해당하는 55개 도서관이 복합건축물형이다. 복합용도건축물 내에 공공도서관을 효율적으로 설치하기 위해서는 도서관의 규모, 위치, 공간구성에 대해서 충분한 고려가 필요하겠다. 그리고 필요하다면 더 많은 상업시설, 학교시설 그리고 관시설과의 복합화가 필요하겠다.

This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.

With the intensification of urban development in Chinese cities, mixed land use in urban centers extends vertically into 3-D and expands its scale from a single building to commercial clusters. The multi-level pedestrian system in city centers also changed its role from one of traffic isolation to spatial integration, where transit nodes, street sidewalks, squares, building entrances, atriums, and corridors are interconnected, both horizontally and vertically, into a whole spatial system, within which pedestrian flows are guided and shopping facilities are arranged. This paper uses spatial configuration analysis of space syntax to examine the impacts of spatial patterns on movement distribution and the business performance of tenant mix in the multi-level commercial system of the Nanshan Commercial Cultural District in Shenzhen, China. The key objective is to better understand the interactions between the socio-economic variables and spatial design parameters of a shopping complex. The research findings point to the importance of multiplicity between syntactic variables and other spatial variables in influencing the pedestrian flows, business performance and tenant mix in highly complex commercial systems. Particularly noteworthy is the relationship between spatial accessibility measures and the location of escalators, and the ways in which individual commercial buildings are embedded into the overall spatial system. The study suggests that this may lead to the preliminary identification of the spatial qualities of effective vertical extensions of mixed land use in a high-density urban settings.

본 연구는 고급화$.$대형화 경향을 보이면서 인근지역에 집적하고 있는 서울시 주상복합건물을 대상으로 '새로운 유형의 주택'에 의해 형성되고 있는 새로운 '주거지역'이라는 관점에서 이들의 주거특성을 살펴보고자 하였다. 주상복합건물 집적지역의 주거특성이 분화된 주거지역적 성격을 나타내고 있는지, 그리고 이들 지역은 도시공간구조적 계층성과 관련하여 볼 때 지역별로 차별적 성격을 보이는지를 분석하여 주거지역 이해에 있어 주택 및 지역성과의 관련성을 파악하고자 하였다. 연구 결과 주상복합건물 거주민들은 소득, 학력, 직업 등 사회ㆍ경제적 특성에 있어 주변 주거지역과 차별적 성향을 나타내고 있으며. 이러한 내부적 동질성이 주상복합 주거지역 간에는 입지에 따라 차별성이 존재함을 알 수 있었다. 이것은 주택의 선택에 있어 사회, 계층적 요소는 중요한 설명요인이지만, 주거지 선택에 있어 주변 지역의 성격은 중요한 요소임을 짐작하게 하는 부분이다. 결국 특정 유형의 주택이지만 어느 지역에 입지하느냐에 따라 주거 입지의 선택과정은 달라질 수 있고, 그 결과 주거지의 성격이 달라진다는 결론을 내릴 수 있다.

Since concrete has evolved to the development of the quality and performance there currently being used civil engineering, as the most important material in the construction sector. But the discovery of alternative building materials and indiscriminate use is negligible. So that is the situation facing the shortage of natural aggregate. Accordingly, this study reviewed the mechanical properties by replacing the aggregate through the mud flat of eco-friendly materials and analyze the usability by adding a high-performance water reducer for promoting workability.

W-Project is 60-story mixed-use residential building complex project in Daegu, the third biggest city in South Korea. There are lots explorable items to be solved to secure structural safety and meet the serviceability requirements. This paper describes what kind of structural system is optimized based on the architectural requirements and structural components design and the grade of concrete strength altered on floors. The defining process of lateral resisting system of outrigger compared to the core ratio of typical plan is illustrated in detail.
