Recently, the interest in a complex building increases rapidly in Korea. High-rise complex is not simply the combination of a residential apartment and a business office as previous but a building with the object of the convenience of the residents familiar with city-life style through adapting the high class life style and new residential culture to the business space, and the efficiency in using the limited building site in the town. This study presents an exploratory analysis focusing the structural system with the help of the extensive survey of the construction site in Korea, and aims a guideline for the structural design and construction of high rise complex. Through the survey, change and development in the design and the construction can be seen as the height and size of the complex grow. It is almost indispensable to design a structural system against lateral forces like earthquake or wind, which is usually measured by story drift ratio or story displacement. Improvement of the structural materials and their usages is also included for the efficiency of the structural system. Useful slab-beam system contributing to the decrease of the story height is still a concern.

Gangform is used as exterior wall forms in the most of apartments. Existing system forms developed for high-rise building, RCS and ACS, are too heavy and over-designed to be applied to general apartments, leading to higher costs. A more simplified rail Gangform(R/GF) is also used, but it depends entirely on T/C for the lift like Gangform. The T/C's legal inactivity time for moving Gangform and materials has increased, and the higher allowances have to be paid for overtime work, thus causing to the cost increase and time delay. Therefore, this study aims to develop an automated Gangform climbing system that can be used universally and economically in apartment houses. The use of the development system is expected to improve the safety of Gangform operations and reduce the workload on T/C.

In Korea, the apartment buildings have been constructed recently in large quantities to provide housing due to the gravitation of population towards large cities. However, because of this trend toward high-rise apartment, a number of problems are occurred such as the deterioration of comfort in the dwelling environment and the lack of solar access right in apartment buildings. In the building law, the sunshine hour and the minimal separated distance between apartment buildings as regulated as the criteria for the site planning. Most of site planners, however, designed the apartment site only following minimum separated distance. As a result, the problem of sunshine hours lack is caused and legal dispute concerning solar access right is also arisen. The purpose of this study is to improve solar access right regulation and to help site design of apartment planning. Accordingly, we execute empirical analysis based on computer simulation in order to find suitable separated distance between typically designed apartment buildings. First, we estimated sunshine hours according to independent building orientation, height, and length. Second, we calculated sunshine hours in various case of apartment arrangement; parallel type, courtyard type, tower type and etc. with various separated distance.

To investigate the air temperature difference between windward and leeward side at high-rise building area, the air temperature and relative humidity data were observed for 10 minute interval from July 9, 2011 to November 30, 2011. The observed data were compared, analyzed and examined to illustrate air temperature between windward side (H Apartment) and Leeward side (W Apartment). The diurnal and seasonal variation of air temperature difference between windward and leeward site were also investigated. After the analysis, the overheat of windward side by $0.4^{\circ}C$ irrespective short distance of two observation positions. It was also lower than those of surrounding air temperature observing stations. It is mainly due to the air temperature decreasing effects of leeward side of high rise buildings.

The objective of this study is to apply performance-based seismic design to high-rise apartment buildings in Korean considering collapse prevention level. The possible issues during its application were studied and the suggestions were made based on the findings from the performance-based seismic design of a building with typical residential multi-unit layout. The lateral-force-resisting system of the building is ordinary shear walls system with a code exception of height limit. In order to allow the exception, the serviceability and the stability of the ordinary shear wall structure need to be evaluated to confirm that it has the equivalent performance as the one designed under the Korean Building Code 2009. The structure was evaluated whether it satisfied its performance objectives to withstand Service Level and Maximum Considered Earthquake.

Construction of high-rise precast concrete apartment is an atractive alternative solution for severe shortage of residential facilities, especially in metropolitan areas in Korea. New building regulations enforced since 1988 requires all buildings higher than 6 storeys to be designed for earthquake. However, we hardly have any experience on seismic design of precast concrete buildings. This paper deals with methodology of seismic design and design considerations of connections for the large panel structures. Also addressed in this paper are studies needed to develop proper seismic design procedures of precast concrete buildings.

Recently, the high-rise apartment housings have become a prototype of the urban residential dwelling in Korea and the numbers of one have steadily been increasing. According to this trend, the strength of the construction materials is also fortified to assure the stability and durability of the buildings. Specially, Re-bar of SD500 type is largely used at the construction sites of high-rise building. This study analyzes the current usage of SD500 high-strength re-bar at domestic construction sites. Through the result of this analysis, we develop Economic Evaluation Model that measure economic efficiency of lap splice and coupler splice, which are most commonly used in connection SD500. The evaluation method was applied to construction sites in Seoul in December 2006, and the result revealed that coupler splice is relatively superior in terms of cost efficiency when the re-bar diameter is longer and the concrete strength is lower.

In this paper performance of the noise barrier which is 53 m long and 6m high, and is located between the high rise apartment and road, is studied by using experimental and analytic method. The insertion loss is measured by using the direct method in accordance with the ISO code, while theoretical prediction is based on Muradali and Fyfe's method (Applied Acoustics, Vol. 53, 49~75, 1998). In addition to the diffraction at the top of the barrier, the waves are reflected infinite times between the building and the barrier, which is equivalent to replacing the building by the infinite series of the image receiver points. In two-dimensional study, the prediction of the insertion loss results in significantly overestimated values compared with the measurement. However three-dimensional analysis shows reasonable agreements, where traffic noise is assumed as incoherent line source and the length of the source is larger than that of the barrier.

Korean traditionally prefer a house with a southern exposure to other styles. Moreover, pretty part of dwelling style in Korea is apartment building. But generally, there are much more north oriented rooms than opposite one in apartment. Generally, most Korean tends to consider the direction of the room as an important factor to decide the arrangement of their furniture. Also, the location of window, door, bed, and closet can affect on the decision-making process of furniture layout. So, the closet position should be determined by not only window direction and door position, but also the furniture arrangement preference of residents. After considering the window and door position, there are 16 alternatives in a room. (Multiplied 4 window directions by 4 door positions under the assumption that the window and the door cannot be on the same side of the wall.) Also, this study analyzed each room style ratio considering the symmetry of each plan by comparing the apartment building plan. This paper studied the bedroom style by analyzing the 180 apartment building plans and survey of furniture layout; the furniture in this study represents bed and desk those are mainly laid in Korean bedroom. Finally, this paper suggested the methodology to find optimal alternatives of furniture and closet layout for high-rise apartment residents, based on the door and window position, and the furniture layout preference of residents.
