Modular buildings are constructed by assembling modular units which are prefabricated in a factory and delivered to the site. However, due to a problem of noise between floors, concrete slab is usually poured at the top or bottom level of a modular unit in Korea. This greatly increases the weight of buildings, but designing vertical members of modular units to resist overall gravity loads is very inefficient. In this study, considering domestic building construction practices, feasible structural systems for tall modular buildings are proposed in which separate steel frames and reinforced concrete core walls are designed to resist gravity and lateral loads. To verify performance, a three-dimensional structural analysis has been performed with two types of prototype buildings, i.e., a residential building and a hotel. From the results, wind-induced lateral displacements and seismic story drifts are examined and compared with their limit values. Between the two kinds of buildings, the efficiency of the proposed system is also evaluated through a comparison of the weight of structural components. Finally, the effect of a floor diaphragm on the overall behavior is analyzed and discussed.

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 suggest visual resource management methods for the national parks and adjacent areas, where visual impacts by high rise buildings such as hotel, condominium, etc. become serious problems. In this study Soraksan National Park has been selected as a case study for landscape management planning. The results of this study are as follows: 1) Comprehensive landscape management planning for National Parks and adjacent areas is necessary to solve visual impact problems by high rise buldings such as hotel, condominium, etc. 2) It is suggested to investigate visual resources and conceptual landscape management ideas, to select landscape control points and lines, landscape management areas, and to prepare building height control plan for proper landscape management plan. 3) In case of Soraksan national park, the landscape management plan includes three landscape management areas : Landscape preservation area, General landscape management area, and special landscape management area. 4) In the part of special landscape management area, it is necessary to introduce landscape impact assessment system to more effective landscape management.

The adaptive reuse of 20th-century high-rise architecture poses important questions about the prevalence of authorized discourses in the heritage conservation field. Based on a two-year teaching experience at Tongji University about the adaptive reuse of the Metropolo Hotel (Palmer and Turner, 1934), an iconic historic high-rise building in the Shanghai Bund area, this paper will show the extent to which disciplinary and urban authorized heritage discourses are present in the development of design and representation strategies in adaptive reuse. Using discourse analysis as a method, this paper will make the argument that disciplinary discourses have a limited effect in the practice of adaptive reuse, which is perceived as a fundamentally creative activity. At the same time, the paper reveals how urban discourses have a much more lasting effect, confirming the intimate links between adaptive reuse and the wider phenomena of beautification and gentrification of high-rise listed areas.

High-rise mixed-use buildings are consisted of various facilities and circulations. Since various facilities and circulations are planned in a single site, circulation planning should be established after identifying the exact characteristics of facility and circulation. To this end, the components of the circulation planning in accordance with the formation of facility types are analyzed through the survey of experts based on Delphi Method. To identify the characteristics of the mixed-use buildings, by figuring out how the elements of circulation planning which are sought to be important by the planner has been reflected through analysis of the correlation between two sections. Researching on the circulation between two sections through Delphi Method and reflected circulation planning, it reaches the conclusion that the circulation of planning on the subject building is applied following the importance. In other words, the components of circulation planning which were sought to be important by the planner are reflected significantly when they planned the circulation planning on that mixed-use buildings. However, in case of design on the outdoor vehicle circulation, minimizing on the vehicle circulation at the 1st floor is not applied for the majority of the subject buildings different from the importance. In early 2000, high end residential buildings designed for mixed-use building have been specialized at vehicle-centered outdoor space and hotel style drop-off. Contrastively, sizable outdoor space at the 1st floor is designed to open to the residents and the local by minimizing the vehicle circulation in recent. Finally it shows that the way of circulation planning has been changed in accordance with time and trend.

Mekuro-Kazoen BLDG. is a complex of office, hotel, and banquet halls, builted in 1991, Tokyo, Japan. This building suggest us various issues about the representation of traditionality in current architecture. We can find the possibility of representation of traditionality in large complex, in past, rarely applicated. Even in Japan, such trial in official building as New Office Building of Tokyo in Sinzuku shows a application only in the elevation plan. In Mekuro-Kazoen BLDG, the applications of traditionality are found not only in external appearance, but also in interior design. And the traditional Japanese gardens in front of building and in atrium enrich the traditionality And the modenity and traditionality in this building are represented simultaneously not deteriorating each other. The issue of representation of traditionality in architecture should be succeed not only in now but also in the future. The method of application need to be studied and improved. The fields of application also should be extended such as large complex buildings and future-oriented buildings.

TORANOMON HILLS is the main building of a large-scale re-development project located in the center of Tokyo. This high-rise building has a height of 247 m and 52 floors above ground, 5 floors below ground, and $62m{\times}80m$ in plan. It is used as hotel, residential facilities, offices, shops and conference facilities. The super structure is mainly a rigid steel frame with response-control devices, using concrete-filled steel tube columns. The underground section is a mixed structure composed of steel, steel-reinforced concrete and reinforced concrete framings. The piled-raft foundation type is used. The remarkable feature of this high-rise building is that the motorway runs through the basements of the building, which makes it stand just above the motorway. This condition is an important factor of the building design. The plan shape is designed to fit along the curve of the motorway. Special columns at the corners are required to avoid placing columns in the motorway. This special column is a single inclined column in the lower floors that branches into two columns in the mid-floors to suit the column location in the upper floors. The cast steel joint is used for the branching point of each special column to securely transfer the stress.
