The purpose of this study was to compare the characteristics of floor plan of $85m^2$-sized housing units with 2-bay and 3-bay and the residents' satisfaction with them. The subjects for analyzing floor plan were six floor plans of $85m^2$-sized housing units with 2-bay and nine floor plans of housing units with 3-bay in the new town, Hwamyeong-dong, in Busan. The floor plans were analyzed based on seven characteristics of floor plans such as the composition type of entrance core hall, the entrance arrangement, width and depth of the housing unit, size of each room, LDK arrangement, arrangement of family bathroom and private bathroom for husband and wife, and balcony arrangement. The subjects for grasping satisfaction with each housing unit were 400 residents of $85m^2$-sized housing units. A half of them lived in housing units with 2-bay and another half of them with 3-bay in the same area. They answered about the degree of satisfaction with the characteristics of each room and the preferred floor plan type if they move to the same size housing units through a questionnaire. The results were as follows; First, the floor plan with 3-bay had more diverse elements than one with 2-bay. Second, the residents who lived in 3-bay housing unit were younger, higher education, and higher income than the ones in 2-bay. Third, the residents who lived in $85m^2$-sized housing unit were more satisfied with and preferred to 3-bay housing units than 2-bay one.

In recent years, new construction methods have been required to reduce the construction cost and increase the available area in an environment where construction work is frequently performed in a narrow urban area like Korea. As a result of these studies, slim floor composite beam has been suggested. Slim floor composite beam can reduce required depth because web of steel beam is embedded in the slab, so it is effective to reduce floor height and increase the available area. The purpose of this study is the floor height reduction evaluation by comparing system consisting of reinforced concrete, steel, and slim floor using square-shape steel pipe. After doing structural design for a typical plan, checked effectiveness by comparing each design plan. It is proven that slim floor composite beam can reduce required depth effectively comparing required materials of other system.

The openness of residential space directly affecting lighting, view, and ventilation leads to the variation of open floor plan type in apartment construction project. This study intends to substantiate the effect to the apartment price by design property of open floor plan based on actual design information of apartment and price. The open floor plan type and associated design property, and actual transaction price of apartment have been considered as variables for analysis by the hedonic price function model and artificial neural networks model. Research findings indicate that the openness affects the price of apartment positively and the three sides open plan is the most preferred with the highest price. This study aims to provide the implication to the developer in planning and design stage of apartment and the purchaser seeking the suitable price by floor plan design.

This study aims to analyze the current status and characteristics of apartment house unit plans towards spatial differentiation. The 172 house units from 32 housing complexes were selected for this analysis. In this study, factors of residential space plan especially in an apartment house are categorized into general characteristics on floor plan and factors for spatial floor plan. The Primary findings are as follows: (1) General characteristics on floor plan are analyzed based on space organization, area and number of bays. Among apartment houses over 40 pyeong, it seems that differentiation is well applied with various space plans available. (2) A result of an analysis on the factors for spatial floor plan shows that planning a living room with two-open-sides seems to be more common in the tower-shaped apartment blocks which are now on the increase. Moreover, many of them are adopting movable partitions to reflect resident's various demands on space plan. Among all, the extra kitchen in the balcony is planned high portion of 80.4%. And diningroom is positioned on the front side of the residential space along with a livingroom(19.2%). More frequently, dining area tends to face the living room(30.2%) according to the result. Besides dress rooms begin to be placed in each of the bedroom, once planned in one bedroom only while 18.6% of the apartment houses are placing new storages in the entrance to solve lack of storage space due to balcony extension.

This study lays emphasis on the development of efficient analytical models for a multistory structure with wings, including the in-plane deformation of floor slabs. For this purpose, a multistory structure with wings is regarded as the combination of multistory structures with rectangular plan and their junctions. In addition, a multistory structure with a rectangular plan is considered to be an assemblage of two-dimensional frames and floor slabs connecting two adjacent frames at each floor level. This modeling, concept can be easily applied to multistory structures with plans in the shape of L, T, Y, U, H, etc. To represent the in-plane deformation of floor slabs efficiently, a two-dimensional frame and the floor slab connecting two adjacent frames at each floor level are modeled as a stick model with two degrees of freedom per floor and a stiff beam with shear deformations, respectively. Three models are used to investigate the effect of in-plane deformation of the floor slab at the junction of wings on the seismic behavior of structures. Based on the comparison of dynamic analysis results obtained using the proposed models and three-dimensional finite element models, it could be concluded that the proposed models can be used as an efficient tool for an approximate analysis of a multistory structure with wings.

In this study, vibration characteristics of concrete slab were investigated through FEM analysis. Four different floor plans with the floor area of $100{\sim}130m^2$ were chosen to be analyzed. Boundary conditions of two dimensional finite element models were determined based on the modal test results. Results showed that mode shapes were formed somewhat different according to the floor plan and the contribution of 1st mode on the floor vibration is generally the highest. Through the transient analysis, it was also found that floor plan, expecially connection of the living room with the kitchen, affected the vibration acceleration levels.

The purposes of the study were to try configuring categorization of floor plans of elderly centers located in apartment complexes and to find out the spatial transfigurations regarding floor plan types. The data for the analysis of the study were collected from 56 elderly centers of apartment complexes in Ulsan by observations and interviews from July 3 through 13, 2012. The results are as follows. Firstly, the floor plans of the elderly centers were categorized into six types, which were 2R+L+K, 2R+LK, 1R+L+K/1R+LK, 1RL+K, 1RLK, and 2R+K/1R+K(no living room). Secondly, there were no salient differences among the plan types for the characteristics of physical environment of the centers. The types of 2R+L+K were relatively big in size and two thirds of the centers had gender-segregated rooms. Lastly, spatial transfigurations was found in sixty-percent of the centers, which included change of spatial arrangement, functional change, and functional addition. Interestingly, the more the spaces were segregated, the more the spatial transfigurations were performed in the way for the integration of functions of the rooms.

Recently, a method of deriving an efficient 2D floor plan has been attracting attention for remodeling of old buildings with inaccurate 2D floor plans, and thus, studies on reverse engineering of indoor Point Cloud Date(PCD) have been actively conducted. However, in the case of a indoor PCD, due to interference of indoor objects, available equipment is limited to Mobile Laser Scanner(MLS), which causes a efficiency reduction of data processing. Therefore, this study proposes an automatic derivation algorithm for 2D floor plan of indoor PCD based on pixelation. First, the scanned indoor PCD is projected on the XY coordinate plane. Second, a point distribution of each pixel in the projected PCD is derived using a pixelation. Lastly, 2 floor plan derivation based on the algorithm is performed.
