Purpose: Building figuration is imperative to perceive the its value, environmental clean status and form. Therefore, maintenance activities of the building exterior are required to keep the housing condition and value. Each household should pay the repair cost which is brought out in the future. For this repair cost, the estimation model would needed to forecast and provide the required cost. This study aimed at providing the estimation model of the repair cost, using the repair survey data between the 2011 and 2014 in Seoul. Method: For these, it took various estimation function of repair cost such as 1st function, inverse function and so on. These above functions would be applied into the building exterior and outdoor facilities which figure the building shape and characteristics. Result: Results of this study are shown ; First, among 11 estimation models, the power function has a better statistics and goodness-of-fit than any other models. Second, the estimation model with a variable of household has a pattern in upward to the right. On the contrary, the model with management area is little downward to the right. Both of them are depended on the estimated parameter of the power function and the parameter smaller than 1.

Nowadays, many research execute about sandwich-insulation wall for durability of wall and retaining insulation performance. But sandwich-insulation, different exterior and interior insulation, need to form-tie which supporting both side form. And because of it penetrate concrete wall, it is worried about thermal-bridge phenomenon to form-tie. So, this research classify penetration type and buried type and analysis thermal-phenomenon of each type's form-tie and insulation performance. As a result, all form-tie type little occur thermal-bridge but penetration form-tie have superior insulation performance and low U-value.

This is an introduction to a stochastic version of E. Cartan′s symplectic mechanics. A class of time-symmetric("Bernstein") diffusion processes is used to deform stochastically the exterior derivative of the Poincare-Cartan one-form on the extended phase space. The resulting symplectic tow-form is shown to contain the (a.e.) dynamical laws of the diffusions. This can be regarded as a geometrization of Feynman′s path integral approach to quantum theory; when Planck′s constant reduce to zero, we recover Cartan′s mechanics. The underlying strategy is the one of "Euclidean Quantum Mechanics".

Small art museums are important objects in the point of view that they are museums to speak for the general architectural culture of current Korea and immediate factors to have an effect on urban street view and urban people's life. In small art museums, form has had plural transfigurational process when we analyze the external component elements or form types, we will find various aspects. In past, composition of form was expressed by simple partition of surface and columv. Now a days, it is expressed with unnumerable formal vocabularies. Although these forms being looked plural, form principle of composition that prescribe it can be rather simple. This study aims to grasp the characteristics and the composition technique of form in small art museums by analyzing compositional elements of it.

Multi-family housings caused several problems related to physical form such as isolation of housing estate, inhumanity of the exterior space, and mismatch with the urban structure. To handle these problems, the purpose of this study is to analyse density elements which have a direct impact on physical forms, thereby understand the characteristics of physical form and also identify a meaning of inter-relationships between them. Therefore both formal constituents and density elements are reformed into respective analyzing indices. From the analysis, physical form and the spatial layout of buildings were more uniform in large-scale housing estates than in medium or small housing estates. However, small-scale housing estates showed various form and the spatial layout of buildings in order to increase the building density.

This paper is a study of the possibility of experience and expression in the architecture of Louis I. Kahn by focusing on the characters of entrance, court and window/wall of his public buildings. In the course of composition, Kahn defined the entrance, court and window/wall as an connecting elements and elements of boundary. The characters revealed by these elements or rooms give the clue to insight Kahn's thought of relation of interior and exterior space or inner and outer space. Following are the characters of these elements. First, a entrance reveals the fact that inner space separates from outer space by connecting these two space and giving the value to inner space as the entity and totality like outer space. The entrance gives its ontological being to human subjects not by vision but experience and expression which is the essence of commonness, that is, Silence. Kahn made the possibility of activity amplify in this common and silent space. Second, this entrance is connected with wide and huge central space not individual spaces of interior space. This extreme procedure of entering makes human subject feel sublime of intoner space. And the central spaces becomes another exterior or another world in the inner world of architecture by the lights from above and by having the boundary wall which shows same pattern of exterior wall. Third, Kahn regarded a window as the giver of lights not as the medium of vision connecting inner space with outer. He tried to connect interior with exterior through the being and character of the light expressed in the interior. And in his buildings, interior space is connected with exterior by expressing the purpose of building, composition of inner space, structural truth and construction facts through the Form, a pattern of wall, details and ornamental joints. By practicing this thoughts in the real buildings, Kahn tried to gave aura to both the interior space and entity of architecture which is regarded as micro universe like flowers, rocks and human beings.

As a circumstantial-existance character (the human character who takes action after grasping circumstances and fears things with reason) the Japanese were more interested in the active doctrines of Wang Yang-ming than other speculative studies. All of people were inhumanely incorporated into the rigorous class system under pressure in the samurai society. In the atmosphere of the society a natural phenomenon was understood as the ksana of change, and instead of the whole, the part was mainly described with emphasis on the reality. Therefore nature came near to the man after being reduced and then was symbolized in the Interior space. Also the classification of spaces, that is to say, the settlement of borders by the social position was shown in the great interior space like a labyrinth. As a self-existance character(the human style who carves out for and does not have a regard other's feeling), however, the Korean were much influenced by the Taoist Idea as they tried to be similar to nature in nature itself. Therefore the idea of Asaniskrota was in their origin. There was a tendency for space to be extended toward the outdoor in Korea, since the Korean people who are speculative and like to be natural tried to be close to nature. Therefore the division of spaces according to class and sexuality and the settlement of borders were already shown in outside by Che-Na-Num(Divided-Mass:Koren's own style). These are closely related with that houses were built after a village settle down in Korea while built before a village settle down in Japan. Architectural space consists of the interior and the exterior. The layout and (on of architectural space has a great variety of characters by region and culture. In other words, it can be understood which has a priority between the interior and the exterior in developing the layout and the form of architectural space. Belonging to the culture area of Chinese characters with Korea, Japan has maintained its own Identity. It has an identity in the layout and form of architectural space as well. Therefore, the architecture and architectural theories of the two countries were compared and analyzed with priority given to the traditional architecture, also the backgrounds of architecture and architectural theories of two countries were examined in this study. This study shows that each country has different characters in how to introduce nature, how to expand space and how to compose windows, including the view of nature and the cult of space. As a result, the space in Korean architecture has relatively the exterior-oriented character but in Japan architecture spatial character is interior-oriented. The interior-oriented character can be relevant to the word 'reduction' and the exterior-oriented character to 'extension' after all. Also it can be thought that each character has a great relation with climate and idea of people in power.

The failure of reinforced concrete structures in recent earthquakes caused concern about the performance of beam column joints. Confinement of joint is one of the ways to improve the performance of beam column joints during earthquakes. This paper describes an experimental study of exterior beam-column joints with two non-conventional reinforcement arrangements. One exterior beam-column joint of a six story building in seismic zone III of India was designed for earthquake loading. The transverse reinforcement of the joint assemblages were detailed as per IS 13920:1993 and IS 456:2000 respectively. The proposed nonconventional reinforcement was provided in the form of diagonal reinforcement on the faces of the joint, as a replacement of stirrups in the joint region for joints detailed as per IS 13920 and as additional reinforcement for joints detailed as per IS 456. These newly proposed detailing have the basic advantage of reducing the reinforcement congestion at the joint region. In order to study and compare the performance of joint with different detailing, four types of one-third scale specimens were cast (two numbers in each type). The main objective of the present study is to investigate the effectiveness of the proposed reinforcement detailing. All the specimens were tested under reverse cyclic loading, with appropriate axial load. From the test results, it was found that the beam-column joint having confining reinforcement as per IS: 456 with nonconventional detailing performed well. Test results indicate that the non-conventionally detailed specimens, Type 2 and Type 4 have an improvement in average ductility of 16% and 119% than their conventionally detailed counter parts (Type1 and Type 3). Further, the joint shear capacity of the Type 2 and Type 4 specimens are improved by 8.4% and 15.6% than the corresponding specimens of Type 1 and Type 3 respectively. The present study proposes a closed form expression to compute the yield and ultimate load of the system. This is accomplished using the theory of statics and the failure pattern observed during testing. Good correlation is found between the theoretical and experimental results.

The most difficult process in the construction of free-form buildings is to manufacture and construct exterior panels designed in a complex way. The façade of the free-form buildings include flat-panels, one-way curvature-panels, and bi-directional curvature panels. To construct these forms, it is necessary to go through the process of optimizing. But as for the optimizing technologies, BIM-specializing companies exclusively protect those technologies, so small construction companies have difficulty in rough estimates. Therefore, this study was aimed to provide the basic data in making the rough estimates of free-form buildings by carrying out the optimizing process for the façade of Dongdaemun Design Plaza and conducting the rough estimates according to the stage of production methods and optimization.
