After 1970 Years. Korea has developed a concept of public domestic housing. But this house is reached the uppermost limit time of using the occupant's satisfying life. Then reconstruction of Apartment house is urgently needed which is developed in Korea. So this study is examined the demolition work on current reconstructing apartment site. for reconstruction. Therefore this research examined the fitted demolition time of low-rise house and characteristics of demolition works. The conclusions from this experiment are shown below. 1. The average day work in clutcher method is shown about 1, 032㎥/Day. 2. The calculations of the term of construction which is produced by the analysis of demolition construction period on low-rise house is below. D(day) ＝ S(day) ＋ (0.272＋0.000902b(㎥))＋R(day)

In this study, the high performance silicone was developed to assure the inter-layer joint in apartment house. The tensile strength, the elongation, the bond strength and the fatigue tests were conducted. As a result, it was confirmed that the performance of high -performance silicone was superior to the existing elastic paint. Therefore, it is expected that it will help to secure the quality of inter-layer joints in apartment houses.

In this study, the performance evaluation of waterproof sealant materials applied to the outer wall of PC apartment houses was conducted. The sealant for PC members must have resistance to movement, and since it is exposed to outside air, weather resistance and water resistance are required.

Recently, much attention has been paid to the problem such as sick building syndrome, which caused by the indoor air pollutant. Volatile Organic Compounds $(VOC_s)$ and formaldehyde have been considered as one of the main reason that causes indoor air pollutant. This study is for introducing and designing thermal performance of super energy saving building by conducting $VOC_s$ and formaldehyde concentration in the 3Liter house. The results of the measurement for 10 months showed that $VOC_s$ and formaldehyde decreased until the guideline concentration. It took about 7 months, and it appeared right after new construction. However, their levels were showed higher concentration in comparison with the ordinary residential houses (apartment house). The main difference of between newly built 3Liter house and ordinary apartment is their air changes, which are 0.67/h for 3Liter house and 4.0/h for the apartment.

This research indicates to controversial point that store equipments were not applying correct development factor in the each apartment house by that change rate by scale and uniformity of form and inefficiency, effect of discount store is increasing in apartment house and progressed research. The result are as follows; First, interior main point of store of that influence greatly to change rate number of store be. Second, being lot area in jar in outside factor of store. Third, discount store separation appeared by leading person who influence greatly to change rate in middle who is contiguity market singleness residential quarter and contiguity existence of commercial district and nonexistence and discount store separation of only outside right near at hand. Construction of commerce equipment may have to consist in practical apartment house after examine various kinds factor such as store indoor, store outside and only outside while plan practical use of systematic and efficient commerce equipment focusing more in efficient utilization of commerce institution that consist after plan that is not planed commerce equipment focusing in development in plan of commerce equipment in apartment house hereafter accordingly.

The aim of apartment house remodeling should be accomplished by three courses; first, to reduce resources and environmental pollution, and second, to overcome social issue such as sick house syndrome on the point of residents' safety, and last, to secure life quality of apartment house healthy and nature friendly through satisfying residents' desire comfortable and safety course. Thus, this study aims to suggest the basic data to improve remodeling of apartment house considering residents' safety on the point of greenness, because of preventing social issue such as sick house syndrome, creating comfortable interior space, deducing indiscreet remodeling, and developing sustainable construction, through grasping customers' demand, and analyzing the correlation between remodeling status and residents' attitude survey of sick house syndrome.

This study examined and analyzed locational conditions of apartment houses in regional small cities to provide basic materials to set direction and index of view management of apartment house and thus the results of the study are as follows. 1. The number of story of apartment houses 'below five story' was 48% and area of apartment house was 'over 500m$^2$ and below 1000m$^2$' in 31% of the whole regions. 2. As a result of analyzing correlations with changes of floor of apartment house by construction year, apartment houses below 10 story were mainly built between 1991 and 1995 and high-storied apartment houses over 11 story were mainly built since 1995 and apartment houses over 21 story were built since 2000 and these high-storied apartment houses were main cause of hindering view of small cities. Accordingly, establishment of guideline of building high-storied apartment house which can be a primary obstacle of urban view and regulations of height are needed.

PC apartment house 15 years have elapsed have various deteriorations by water leakage in roof and wall. The prior investigation such as investigating of leakage repair history of PC apartment and the field investigation were carried out to solve the water leak problem in its structure. The path of water was analyzed on the parts of greatest water leak such as roof parapet, roof floor, side wall, corridor and balcony. As a result, the specific path of the water leakage was identified in various structure units.

This paper descrides on the economical design of apartment house. * The optimal problems are made by considering the objective function which minimize the construction cost of frame. * The object functions are taken as the codfficient equations of the cost function for a unit area. * Constraints are the design limits defined by the ultimate flexural strength, the ultimate shear strength. the minimum thickness, and the ratio of steel in accordance with ACI 318-89 Code. * Optimization is achieved by optimum nonlinear GINO(General interactive Optimizer)program. In design examples, it is compared with the optimum design results of apartment house and underground parking lot for structural systems.

Because of the high airtightness and insulation of the building, indoor environment has been largely polluted resulted from insufficient ventilation and occurrence of new air pollutant. These factors have made worse indoor air quality and caused symptoms of the SHS(Sick House Syndrome), MCS(Multi Chemical Sensitivity). The purpose of this study is to present the fundamental strategies for improving the Indoor Air Quality(IAQ) in newly-constructed apartment buildings. To investigate the concentration of indoor air pollutants such as Formaldehyde and VOCs, the field measurement were conducted.
