  • Currently in the country, the necessity of seismic analyses is increasing due to the increase of demand and interest in seismic design. Especially, shear wall apartments are constructed mostly for a residental building so seismic analyses for the apartment are actively executed. For the seismic analysis of the shear wall apartment, it may be not efficient in time and effort to model the entire structure by a finite element mesh. Therefore, an equivalent model is needed to simulate the dynamic behavior of the structure by decreasing the number of degrees of freedom. In this study, a method to form an equivalent model that is simple and easy to use was proposed utilizing effective mass coefficient that is highly correlated to mode shape of the structure. This equivalent model was obtained by replacing a shear wall structure with an equivalent frame structure having beams and columns. This model can be used very effectively when excessive seismic analyses are necessary in a short period because it can be operated in any commercial program and reduce the analysis time. Also, it can model floor slabs so it can represent the actual behavior of shear wall apartments. Furthermore, it is very excellent since it can represent the asymmetry of the structure.

  • In the 1970s, the full-scale development of the area now known as Gangnam began, ushering in the era of real estate investment on apartments which transformed housing styles in Korea. Apartments were pitched as the most ideal type of housing, creating a competitive market of high demand and skyrocketing prices. The apartments were also viewed as a means of quick asset investment among middle-class Koreans. Within this apartment frenzy stood the female real estate speculator, the bokbuin. This study seeks to locate the bokbuin in the real estate development market after the late 1970s. The apartment speculation boom cannot be attributed to the bokbuin alone, yet she became the target of public anger and criticism, singled-out as being responsible for fueling illegal and unethical investments. The apartment boom of the 1970s was in fact generated in large part by the government, developers, construction companies and realtors. While their pursuit of profit was deemed as legitimate, the bokbuin's conduct was mostly tainted by presumed illegitimate and greedy motivations. This study problematizes this gendering of real estate investment and treat the bokbuin as a byproduct of the family-centered culture in East Asia. Analyzing Im Kwon Taek's film "Mrs. Speculator", Park Ki Won's conte, "Bokbuin", Park Wan Seo's short story, "Children of Paradise", "The People of Seoul", this study shows that bokbuin's pursuit was not hers alone; it was the collective pursuit with her husband for the enhancement of family finances. This stud y argue that the bokbuin embodied the thickly misogynistic climate of the 1970s that projected the chaotic rise of greed onto the woman.

  • The main purpose of this paper is to develop seismic fragility curves for existing reinforced concrete, RC, buildings based on the post earthquake field survey and the seismic performance using capacity design. Existing RC buildings constitute approximately 65% of the total stock in Algiers. This type of buildings, RC, was widely used in the past and chosen as the structural type for the future construction program of more than 2 millions apartments all over Algeria. These buildings, suffered moderate to extensive damage after the 2003 Boumerdes earthquake, on May 21st. The determination of analytical seismic fragility curves for low-rise and mid-rise existing RC buildings was carried out based on the consistent and complete post earthquake survey after that event. The information on the damaged existing RC buildings was investigated and evaluated by experts. Thirty four (34) communes (districts) of fifty seven (57), the most populated and affected by earthquake damage were considered in this study. Utilizing the field observed damage data and the Japanese Seismic Index Methodology, based on the capacity design method. Seismic fragility curves were developed for those buildings with a large number data in order to get a statistically significant sample size. According to the construction period and the code design, four types of existing RC buildings were considered. Buildings designed with pre-code (very poor structural behavior before 1955), Buildings designed with low code (poor structural behavior, between 1955-1981), buildings designed with medium code (moderate structural behavior, between 1981-1999) and buildings designed with high code (good structural behavior, after 1999).

  • The Qualitative improvements of outdoor spaces are unsatisfactory in comparison with that of indoor environment in existing apartments. Lately construction companies are differentiating the outdoor spaces of apartment complexes to meet needs of residents. However, high-rise buildings inherently have limitations on providing exposure to the outdoor settings and inappropriate lightings could have serious impacts on physical and psychological health of residents. Therefore, the purpose of this study is to provide useful information for the luminous environment of outdoor spaces through the analysis of current apartment complexes' lighting plans. Outdoor space of branded apartment complexes in Seoul, built after the year 2003, were researched. Through site visits, illumination level and lighting plans were investigated classified into entry area, passage area, plaza, rest area, exercise area, and play area. With the result, illumination level of apartment complexes researched was lower than KS illumination standard in all areas and the lighting plans were mostly shown in different condition of first intended lighting plan because of insufficiency of maintenance in lighting system. Therefore, it is need to provide better luminous environment to make outdoor space more lively and energetic at the night time.

  • Hanok is Korea's traditional housing, which is build detached unit. Most of the People who live in the environment of residential high-rise apartments likes new residential environment, and pursue eco-friendly homes, health homes, especially traditional Hanok was reassure potential. In urban context, resident think more compact land use in Hanok also, because Hanok is dissatified in compact land use, and it should be build as more economic aspect. The purpose of this study is to propose a typology which traditional Hanok also can be build higher land use and traditional values as a modern housing type; First of all, clustered Hanok is formed by traditional houses and interior spaces in modern house., and its types are configured by lifestyle of modern and image element of traditional Hanok. This kinds of clustering Hanok can be seen from historical city, but the trends is a minority of the housing type and form. Now, the modern clustering Hanok, even though handful of cases, appears as sustainable housing type, its possibilities as a new housing should be more detailed researches. A elements of Modern cluster Hanok discused in layout, plan, envelopment of house, structure, roofs, and the coordination of the element can be so much diverse.

  • The purpose of this study was to analyze the preferences for the physical features of senior congregate housing. The survey was conducted among middle-aged people in their fifties, who lived in Seoul, using the systematic random sampling method. The data were collected from November 3, 2003 to November 14, 2003 and the final subjects consisted of 498 respondents. Various statistical methods such as frequency, mean, cross tabulation, t-test, factor analysis, and multiple regression were used in this study. The results of this study were as follows. Firstly, most of the respondents preferred 55 to $70m^2$ sized individual units and they rarely wanted smaller units of less than $35m^2$. Individual units of one or two bedrooms were also preferred by future users. Small towns were preferred to large complex. For housing type, they preferred row houses or single detached houses to high-rise apartments. Secondly, there were no significant statistical differences between income and the preference of the physical features. From the results, we concluded that senior congregate housing should be developed not only in accordance with the users' preferences but also over a certain minimum physical quality level, regardless of the users' income.

  • Most old apartment housing have been replaced with new ones by means of the reconstruction. But with the change of the construction environment, remodeling is introduced as a new alternative for the replacement. Remodeling is expected to reduce national loss owing to the early reconstruction of old apartments resulted from economical and functional deterioration. But there still remains a lot of problems to be first solved for Remodeling. One of those is to figure out how to perform an economic feasibility analysis effectively. The researches of remodeling done under the rally stage are not sufficient in economic feasibility for apartment housing. Therefore, this paper suggests an effective method for the economic evaluation of remodeling projects focusing on a rental high-rise apartment.

  • The purpose of this study is to investigate the theoretical origins and characteristics of Korean Apartment that became a dominant housing type of Korea by comparing it with the ideas of Le Corbusier, Siedlung and Hilberseimer. Korean apartment is different from Corbusier's idea in that it has no vision for new community in modern society. Formal typology of apartment also differs from Corbusier's unite which embodied a new collective way of living in modern society. In that Korean apartment was introduced as a means to provide houses to urban worker and to solve the housing shortage, it was close to the idea of Siedlung. However, unlike Siedlung Korean apartment was based on urban ideology and not a social housing. In terms of it's repetitive form, Korean Apartment resembled Hilberseimer's proposal for capitalistic metropolis. However, it differs from Korean Apartment in that the latter has no utopian vision of new order So, while reflecting fragmented ideas of modern utopia, Korean apartment is architecture without utopia.

  • Worldwide, the building energy simulation becomes inevitable step for predicting the energy consumption in building. In simulation process, the expertise is required for the accurate analysis results. In Korea, however, most of user use the inconsistent data with Korea circumstance. In this step, we need to construct the standard input data matched building in Korea. In this study, electricity consumption of apartments in Daejeon is analyzed. The yearly data of a apartment complexes of 2009 are analyzed as monthly, daily(week and weekend), timely, and completion year. With this result, we are able to predict the demand pattern of electricity in a house and make the schedule by demand pattern. The results of this study are followed. The averaged amount of electricity consumption in winter is higher than summer because of the high capacity of heating equipment. All of the house has electric base load from 0.26kWh to 0.5kWh. The average of the electricity consumption of month is shown as 326.7kWh. A week is seperated as 4 part such as week, weekend, Saturday and Sunday. During week, the average of timely electricity consumption is shown as 0.442kWh. The Saturday consumption is 0.453kWh. The Sunday is 0.461kWh.

  • Research on elevator noise has mainly focused on the cause of its occurrence and measures to reduce it. There is still insufficient research on how to accurately measure and evaluate elevator noise. There is a measurement method established as an international standard for the measurement method, but it is also difficult to apply to high-rise apartments, and there are many cases that do not closely reflect the characteristics of elevator noise. In order to solve this problem, a study was conducted to improve the elevator noise measurement method in the current standard. In this study, the characteristics of elevator noise were closely identified. Through frequency analysis of the elevator noise and other equipment, it was verified that the elevator noise is noise with different characteristics from other equipment. Elevator noise was compared with heavy floor impact noise, which is a representative structural transmission noise, as structural transmission noise. Elevator noise was compared with heavy floor impact noise, which is a representative structural transmission noise, as structural transmission noise. The correlation between bang machine and rubber ball was found to be very high at 0.9 level. As a result, it was verified that the mid-low frequency band of the elevator noise is the main structural transmission noise and cannot be evaluated together with other equipment.
