The purpose of this study is to find the characteristics of space utilization and the problems that follows after converting in a new developmental residential area. This study used the content-analysis method and analysis was made on the floor plans for 95 different conversion cases. Above all, 190 unit plans (the unit plans for conversion before and after) were analyzed. The results of this study were as follows; 1) There were 8 types of conversion according to such usages as residential, commercial and residential-commercial buildings. 2) In the case of conversions, from residential to commercial, there was a tendency each floor was integrated to exclusive use for commercial or commercial with small portions of residential usage. And in the case of conversions from commercial to residential, there was a tendency that all space of each floor were changed to exclusive usages for residential purposes. 3) In case of usage conversion from commercial to residential, there were constraints for balcony installation, because of its original lot-structure and building equipments. Also, when the basement was converted for residential purpose, there was no possibility for an extra lighting or ways to ventilate the area.

The fire in Ulsan in 2020 was a 33-story residential and commercial complex with about 90 injuries and more than 10 billion won in property damage, and considering the recent increase in high-rise residential and commercial complexes, the risk of similar fires is high. As can be seen through the residential and commercial complex fire case in Ulsan, life-based fire safety standards need to be established to minimize casualties. Therefore, the purpose of this study is to draw improvements for the development of human safety standards for high-rise residential facilities in the future through comparison with the Korean Building Act, Firefighting-rellated Acts and the U.S. NFPA 101.

This investigation is to question as to whether and how much urban residential superblocks have changed the uses of facilities, as compared with original zoning plan. The difference between the original plan for 'land use' in 1960's and current 'building uses' has been examined on six superblocks in Seoul, and the reasons for change were analyzed. Investigation results are as follows: As the original urban planning was intended for use-purification by the subdivision of zones in a superblock through zoning, current buildings uses are different from the land-use. Commercial facilities are located in residential zone along community paths because of the necessity, and business buildings are placed on the appropriate-sized lots in the middle of residential blocks, due to the need of small and low-rent offices. Also, different types of residence have been built on convenient locations in commercial zone to meet various housing needs. In conclusion, the current zoning system plays a role of controling the volume of buildings rather than the use of land. Therefore, mixed use of land, not functional separation, becomes a natural phenomenon taken place in the contemporary cities, and it is high time to adopt a mixed-use zoning system.

In order to determine the violation of right of light impact at adjacent residential area by high-rise building, analysis on the right of light for high-rise residential commercial complex building block at Gahngnam-ku, Seoul, Korea was carried out using Google Sketchup Pro. After the analysis th sunshine duration of B apartment decreased from 5 hours 16 minutes 3 hours 48 minutes by I hour 42 minutes after construction. It shows that the total sunshine duration is less than the Seoul City Government Standard which is more than 4 hours a day, or more than 2 consecutive hours. Lowering the heights of apartments by 54m would increase the total sunshine duration which would meet the Seoul City Government Standard by four hours seven minutes. Problems that rna lead to the violation on the right of light in the adjacent area should be discussed in advance and minimized by analyzing the right of light among buildings and structures which are scheduled to be constructed on the site during construction penni! process when high-rise building is proposed.

Apartment design in residential Area is restricted by building distance limit code. Building distance limit decreases gradually to the 0.8H(height), and residential area has 250% site area ratio by building code, so site using has become efficient. In this study, examine the relationship between present building distance limit and right of daylighting environment by computer simulation. As well, high-rise residential officetel and multipurpose residential building becomes increase in commercial non-residential area. In the domestic, residential type multipurpose building made at the business area or central business area has 400∼800% site area ratio by building code. However, at a dweller's point of view, there are much lacks of environmental consideration to provide suitable daylighting environment. And, POE: Post Occupancy Evaluation is not completed yet. In this study, however, progress architectural environment prediction, basis by right of daylighting, and examine the possibility of daylighting by architectural distance limit code in residental area and by high-rise, high-density residential building in non-residental downtown area.

Seismic isolation technique has been applied mainly in low rise buildings and its seismic performance was satisfactory during Kobe Earthquake. However, in the case of medium and/or high-rise buildings, mid-story isolation could be more technically feasible than base isolation to reduce earthquake forces. In this paper, the seismic effectiveness of mid-story isolation in medium and/or high-rise shear building as well as low rise shear building was evaluated analytically. After verifying the effectiveness of mid-story isolation technique, this method also applied in residential-commercial building. It was found that mid-story isolation, that is isolation between upper residential area and lower commercial area, could reduce inter-story drift and floor shear forces comparing to the conventional fixed base.

The purpose of this study is to investigate elasto-plastic behaviour and estimate ultimate resistance capacity of the residential-commercial building subjected to lateral force along the height of structure. Four types of residential-commercial building are chosen as analytical models and investigated by pushover analysis. Pushover analysis estimates initial elastic stiffness, post-yielding stiffness, and plastic hinges on each story of structures through three-dimensional nonlinear analysis program CANNY-99. Skeleton curve of bending stiffness model is bilinear, shear stiffness model is trilinear, and axial stiffness model is elastic. Skeleton curve of axial stiffness model has the axial compression and tension stiffness of reinforced concrete members. This study presents the change of inter story drift, story stiffness and hinge of story and member.
