This study aims to classify the framework and arrangement of interior columns (Naeju) which are used in single-story Buddhist halls into several types, and to develop a theory on the process of changes among those types. Since interior columns are building materials which hold up the roof structure and make partitions in the interior space of halls, their framework and arrangement is closely linked to the development of building technology and is expected to reflect new architectural needs. The kinds of interior columns classified by the shape of framework are goju, chaduju, oepyonju, naepyonju. The arrangement of interior columns can he classified by two methods: One which counts the number of the interior column arrangements in a hall, and the other whose classification relates with the side wall columns - Jeongchibup and yijubup. With the combination of these classifications, we can divide the framework and arrangement of interior columns into 8 types From the remains of Korean and Chinese Architecture, we can presume that before the late-Goryo period, jeongchibup had always been applied in the construction of Buddhist halls, and gamju(column reducing) had only been used in examples of small scale. After the founding of Choseon Kingdom, however, national policy had weakened the economic power of Buddhist temples. Because of that, large-scale outdoor Buddhist mass was replaced by small-scale indoor mass, and for this reason, though the scale of Buddhist halls became smaller, the need for a broad interior space became stronger. Thus in early-Choseon period, reduction of interior columns became widely spread. Those types of framework and arrangement of interior columns where yijubup was applied were developed because the rear interior columns arrangements, in order to expand the interior space, have moved backward. Among these types, yiju-goju and yiju-chaduju were developed for the Buddhist halls with paljak roof(hipped-gabled roof), where the load of their side eaves caused structural problems at the side walls. And oepyonju type was for the small-scale and middle-scale Buddhist halls which needed more interior space but didn't want the extension of roof structure. From the local and periodic distribution of each types, we can conclude that the types jeongchi-goju, jeongchi-chaduju and yiju-chaduju have been settled as typical technique of local carpenters. Oepyonju was developed later than the other types, but for its merit of low cost, it became a popular type across the nation.

The purpose of this study is to examine the effect of column spacing and beam size on the lateral displacement and shear lag phenomenon in bundled tube system. According to the parametric study in which the spacing of columns, the size of columns and girders in bundled tube were selected as a parameter, it is the most efficient to increase the size of the interior columns with the largest reduction of lateral drift if the steel tonnage of a frame can be increased. It was noticed that the shear lag was affected more by the exterior stiffness factor and ratio than by the interior ones when column spacing was changed, and when the size of column was changed, the reverse phenomenon was happened. And The change of column spacing affected shear lag, lateral drift, and tonnage more than that of column size or girder size.

Frame composed of concrete-filled steel tubular columns and I-shaped steel beam has been researched in order to development reasonable connection details. The present paper describes the results of an experimental program in four different connection details. The connection details considered include through-bolt between I-shaped steel beams and concrete-filled steel tubular columns and two details of welded connections. One of the welded connection details is stiffened by angles welded in the interior of the profile wall at the beam flange level. The specimens were tested in a cruciform loading arrangement with variable monotonic loading on the beams and constant compressive load on the column. For through-bolt details, the contribution of friction and bearing were investigated by embedding some of the bolts in the concrete. The results of the tests show that through-bolt connection details are very ductility and the bearing is not important to the behavior of these moment connections. The angles welded in the interior of the profile wall increase the strength and stiffness of the welded connection detail. In addition, the behavior curves of these connections are compared and some interesting conclusions are drawn. The results are summarized for the strength and stiffness of each connection.

This study aims at examinating the change of architectural technique in the residential district of Seoktanri(石灘里), and then extracting the restorable types from it. The constructive technique was advanced in the composition of walls and the use of footing. The arrangement of columns was developed to standing them in a row and three rows in the center of interior space. In the light of excavated relics and the position of furnace, the interior space is seperated into cooking-heating, working and storing space. By the difference of height and the slope, the floor is divided into two parts which are low and high. According to the arrangement of column-holes, the types of roofs to be restored are as follows; the gable roof without column-hole, the hipped roof with center-column-holes(中央柱孔) in a row and the gable roof with center-column-holes in three rows.

In the phase of an architectural designing, the Pinakothek der Modeme in Munich is considered that it is influenced by the Altes Museum in Berlin. The critical elements were composed of the classification of Tominaka and my points of view. Two buildings were analyzed for comparison by six elements, such as, a spatial construction, an organization of plan, an organization of section, a composition of elevation, a method of construction and a composition of mass. The results of the analysis were that the design of the Pinakothek der modeme was influenced by the Altes Museum as follows: 1)the use of square and circle in the composition of plan, 2)the use of a curtain of columns and a formation of the transitional space between columns and front wall, 3)the location and function of the main stairs and the inner court, 4)the arrangement of exhibition halls, 5)the covering of dome, 6)the unification of spaces of different floors through the rotunda. This study may be helpful for any architects who make a decision of the method and the range of reference to some other building in the beginning of design.

The origin of the Roman public basilica is Rome's indigenous style morphologically but actually it seems that developed the Greek semi-open style stoa into the Roman practical interior space. In the early ages, the arrangement of Roman forum had been planned high symbolical temple as the center but gradually changed into the basilica centered which were used often by citizen. Through the Roman period, the important types of early Roman basilica have Fano basilica in the first century BC, Pompei basilica of mid period in the first century AD, Doclear basilica with apse as late type in the second century AD. Pompei type well characterized the feature of Roman public basilica among them. The result of the floor plan analysis shows that the long side access to the interior space is over 76 percent of examples and nearly 70 percent have no apse and the average of vertical horizontal length ratio presents as 1:2.3. The typical plan of Roman public basilica can be defined that most of access are being entered from one of the long side, and most of basilica have no apse, and normally having inner columns arranged in one or more concentric rectangles around nave as a center.

In this study, the plane type of main building relics of unified Silla period house site which excavated in Gyeongju city after 1990s was classified and the architectural characteristic of them was investigated. The chronology of building relics in Silla capital city site was mostly known as 8-9th century, and by standard of column arrangement, the plane types of them could be classified as grid type, front veranda-grid type, outer column type. The outstanding characteristic of plane is wide span and open front veranda. In most relics the span were over 4 meters, and inner foundations for small post and strip foundation were found between columns. The front veranda added type buildings were composited of enclosed main room and open front veranda, and column arrangement of them dose not fall into line in most case. Thus it thought that the structures of enclosed main room and open front veranda were independent. The interior space of enclosed main room were divided two rooms by partition wall in some case. In this case, one room is enclosed by wall, and the other room has open front side. This plane is considered for the pleasant life in cold winter and hot summer.

Early Buddhist rock cave temples of India, in spite of being an origin of Buddhist temples, has little been studied in Korea. After field studies and an interpretation of their forms in conjunction with religious life, precedent theories are supplemented and refuted as follows. Starting from the 2nd century B,C., Buddhist ascetic disciples digged residential rock caves, called vihara, for protection from monsoon rain and hot weather, A typical arrangement was settled -a courtyard type, with 3 side rows of tiny one-person bedroom and a front veranda with columns. Also digged were Chaitya caves, in line with viharas, to worship, which is the tumulus of Buddha's relics. I suggest that the original type of chaitya a simple circle cave with a stupa, suitable for circumambulating ceremonies. I refute the existing theory presenting Barabar caves of Ajivika as a chaitya origin, featuring empty circular room without a stupa. I also interpret a typical apsidal plan as being a simple result of adding a place of worshipping rites in front of the stupa. Enclosing columns around a cylindrical stupa is a result of reinforcing both the divine space and circumambulating ceremonies, with elongation toward hall. Finally the chaitya came to have a grandeur apsidal plan with high vault ceiling nave and a side aisle as in Western cathedrals with large frontal horseshoe arch windows. The Buddha image, which had become a new worshipping object, was integrated into the stupa and interior surface. First the stupa and then the statue was introduced to residential Viharas. Therefore, I suggest that the vihara should be renamed as 'chaitya' as a worshipping place, by establishing statue rooms without bedrooms at all. The functionally changed vihara is similar in form to a 'rectangular type of chaitya', little known and developed in different routes. A columned inner courtyard gradually becama an offering place, like Hindu mandapa, Buddhist caves ware changed to a kind of Tantric and Hindu temple by means of statue worshipping offering rituals.

Due to aesthetic, economic, and structural performance, the use of structural hollow sections as columns in both continuous moment resisting and nominally pinned construction is attractive. Connecting the beams to these sections is somewhat problematic as there is no access to the interior of the section to allow for the tightening of a standard bolt. Therefore, bolts that may be tightened from one side, i.e., blind bolts, have been developed to facilitate the use of site bolting for this arrangement. This paper critically reviews available information concerning blind bolting technology, especially the performance of fasteners in shear, tension, and moment resisting connections. Also provided is an explanation of the way in which the results have been incorporated into design guidance covering the particular case of nominally pinned connections. For moment resisting connections, it is concluded that whilst the principle has been adequately demonstrated, sufficient data are currently not available to permit the provision of authoritative design guidance. In addition, inherent flexibilities in the connections mean that performance equivalent to full strength and rigid is unlikely to be achievable: a semicontinuous approach to frame design will therefore be necessary.

Purpose: It is important to plan the ward module at a time when the size of beds, the floor area, and the construction budget are all set prior to the hospital design. In this context this study aims (1) to derive various factors affecting the ward module, and (2) to analyze the appropriate room module according to the type. Methods: Design factors related to hospital modules are derived through precedential studies, and the types of ward elevation are classified by reviewing the drawings of 18 case hospitals. And the detailed dimensions and area of the derived elements are analyzed. Results: The X-axis modules of the ward are switched to long span structural columns of 9.9 m, 12.6 m and 13.2 m, but the ward modules still represent 6.6 m. The Y-axis module of the ward shows a dimension of 9 to 9.9m in the process of changing a multi-person room into a four-person room. Type A of curtain wall with columns located on the wall of the room and type B of curtain wall located in the center of the room are analyzed due to their variations. The square window type, which forms the elevation of the square window by exposing the columns to the elevation, and the outframe type, which protrudes from the structural columns and beams, have elevation designs limited. There are, however, no obstacles to the interior space of the hospital room, so the wall composition and furniture arrangement are expected to be free. The ward area of Curtain Wall Type A, which can secure an effective area of 5.9m*5.0m, are 52.1m². The Curtain Wall Type A, Square window type, and the outframe type are 49.8m². Implications: As part of the hospital standard module plan for economical and reasonable hospital building planning, a type was proposed in this study in conjunction with the external design. It is hoped that it be a base for standard module research linked together to the Central Treatment department, Outpatient department and underground parking lot.
