Currently structural design of basement exterior wall is based on the assumption of boundary condition of plate, which may lead to erroneous results. In this study, the behavior of basement exterior wall subject to earth pressure and hydraulic pressure is investigated using linear finite element analysis. Parametric studies are conducted to investigate the variation of moment and shear force according to column-to-wall stiffness and aspect ratios. Using these numerical results, modification factors applicable to the design of basement exterior wall are presented. Design example is illustrated, showing satisfactory results.

When doing underground excavation works for the purpose of constructing large underground structures for a building in the limited space in downtown area, the stability of the adjacent ground must be top priority, and to accomplish this, it is essential to review the retaining wall construction carefully. H-Pile, which has been mainly used as a stress-carrying material in temporary earth-retaining structures, is most likely to be abandoned after completion of the works for the basement exterior wall in relation to contiguous bored piles, so it will result in a waste of material. To improve this situation, Basement Composite Wall where H-Pile and basement wall are compounded, has been developed. This wall is being used most frequently in many local construction sites. In this study, five specimens are made in order to evaluate the shear resistance of the basement composite wall and tested. Test parameter is the composition ratio and wall thickness according to shear connectors. Test result shows that the shear strength is improved when the composite ratio is increased but the magnitude is not much. A formula, which considers the contribution of concrete, web of H-pile as well as flange' effect in calculation of shear strength of composite basement wall, is suggested and used to calculation of the strength of specimens. It is found that there is a good co-relation between test result and the calculated one by the formula.

Until 1980s, Korean elementary school architecture has been stereotyped by standard drawings. But there have been very few researches focused on this subject, especially regional one. As an attempt to improve these conditions, this study reviewed standard drawings of elementary school architecture by Education Board of Seoul in 1964 and 1975. Both standard drawings were reviewed through items such as components making a set of standard drawings, floor plan, elevation design and subsidiary facilities. They have rectangular unit classrooms, single-corridor block plan and plain exterior having no symbolic images, which are the characteristics of typical Korean school architecture until 1980s. On the other hand, they reveal the unknown characteristics such as double-corridor block plan, classrooms in basement, toilets of conventional type placed on every floor and changes in details of openings and exterior wall.

According to the statistical surveys and studies, insufficient maintenance in the use of existing buildings caused fire and collapse accidents. In this respect, I analyzed the data managed by the current building maintenance and inspection system to find out the actual state of safety management and proposed two significant results. First, regarding the state of the buildings, the safety management status of the small-sized ones, where 20 years or more passed after construction, is the worst and a priority improvement plan is required. Second, there are eight deeply concerning factors for the fire incidents and collapse accidents of buildings. In the order of high risk, these factors are structural strength (seismic design), exterior wall finishing material, basement floor, interior finishing materials, other evacuation facilities, corridors stairs entrances, rooftop, fire partition. We need to have more special designs and management plans regarding high-risk factors as a system to prevent accidents in the building.

Recently, the recognition is changing about cultural heritage, and the various types of buildings or facilities of modern or contemporary times have been designated as cultural properties after that Registered Cultural Properties System is enforced. The purpose of this study is to survey how the newly born the historic buildings of modern or contemporary times through the remodeling process of the Studio 'Byeol'(the Training Center for Performers of Korean Traditional Music) in the National Theater of Korea so-called a microcosm of performing arts history. In the process, it will examine the merits and demerits of various alternatives and the direction of the remodeling etc., and propose an utilization as a basic data of post evaluation for the remodeling of a historic building. The result are as followings. Firstly, the remodeling that gave a new physical properties to a building can be used a method of conservation and reuse on a historic building. The remodeling of a historic building must be eclectically progress between the owner and the citizen or the economic value and the historicity conservation. And, the remodeling of historic buildings such as the Training Center for Performers of Korean Traditional Music must consider the conservation of the exterior walls in whole or in part at least. Secondly, an architect Lee Hee Tae(李喜泰) who had been to develop his own architectural vocabulary and to test based on the korean traditional architecture and the Training Center for Performers of Korean Traditional Music must be newly evaluated today. Lastly, the remodeling alternatives of the Training Center for Performers of Korean Traditional Music have been analyzed with three types, which is 'repairing only the interior which maintains the size and an appearance of present', 'extending the outer wall to the external column line', 'extending the basement'. And, it was analyzed with the appropriate final decision that it remodels only the interior in the current situation because of a historicity, a budget, a relevant law etc.
