The purpose of this study is to identify the context of enactment and the application to the design of in 1916. The characteristics of the composition are as follows; First, One-third are general rules of common application, Second, regulations related to cold resistance are set up separately, last, each of the 21 articles was equally divided for schools, hospitals and prisons. The standard reflect the times of the mid-1910s. The Trend of using of the Western Building System in the 1910s, The need for building construction against cold weather, and Actual conditions of renovation, extension and new plans by facility. Furthermore, the fact that various regulations concerning standard design were enacted and used in various Japanese institutions around the 1910s may have influenced the establishment of the standard. Meanwhile, after checking the status of the reflection of the standard on the planning drawings of the government facilities around 1916, it was also found that the plan was carried out in compliance with the provisions of the standard, and that the items already applied before the enactment had been organized into architectural standards.

Torsional irregularity is one of the most probable types of horizontal irregularity and existence of this irregularity in most of the structural loading codes is determined by calculating the ratio of the maximum to the average story drift. No specific method has been previously recommended by the codes to calculate the mentioned ratio in the response spectrum analyses. In the current investigation, nine steel building structures with different plan layouts and number of stories have been analyzed and designed in order to evaluate the efficiency of three methods for calculating the ratio of the maximum to the average story drift in the response spectrum analyses. It should be noted that one of these methods is the approach used by current version of ETABS software andother ones are proposed in this paper. The obtained results using the proposed methods are compared with the time history analysis results. The comparisons show that one of these methods underestimates the mentioned ratio in all studied models, however, the other two methods have shown similar results. It is also found that the plan layouts and irregularities can affect how these methods estimate the ratios compared to those obtained by the time history analysis. Generally, it can be concluded that all of these methods can properly predict the ratio with acceptable errors.

The objective of this paper is to clarify the architectural characteristics of the Korean-Western eclectic houses at Ojeong-dong Missionary Village in Daejeon city, focused on the spatial and structural changes due to eclecticism. The consequences of the comparative analysis between the eclectic houses and two reference buildings, Myeongjae residence and Moore house, are as follows. The diverse aspects due to eclecticism can be summarized as two concepts; transformation and simplification. The transformation has appeared in the characteristic spatial elements such as an-madang, entrance and corridor, in the territory organization and the connection between building and yard, and in the roof and wall structures. The simplification has appeared in the layering of the building space, and in the joint of roof and wall. The methods of eclecticism and the resultant aspects from them that are clarified through this study are expected to be referred in examining the new possibilities of the hanok.

With the effect that the Yipsu-ryong(入首龍) of Ju-san(主山) influenced on the layout in the view of geomantic topography(形勢), how Ahn-san(案山) affected the layout plan of the Korean academics of classical learning(書院) is researched. And how the "Jirisinbeob(地理新法)" which had been written by Ho-sun-sin(胡舜申) was applied to the Korean academics of classical learning in the view of Li and Ch'i(理氣) is studied. In Fengshui, the method to pick out a site and to confirm the direction for building construction was divided into two, one of them was 'the geomantic topography', which included 'Ju-san following type(主山順應形)', 'Ahn-san stressing type(案山重視形)' and 'Ju-san & Ahn-san complex type(主 案山混合形)'. And the other is the 'Rule of direction(向法)'. The Korean academics of classical learning was applied by the geomantic topography of Fengshui for its layout and direction, regardless of political, regional and period factors. So when the Sa-rim(士林) needed to set direction for the Korean academics of classical learning, the ground that was appropriate to the geomantic topography of Fengshui was selected. Therefore, the Sa-rim who was abused in Neo-Confucianism had a mind of stressing geomantic topography of Fengshui and they applied it positively for building construction.

This study aims at searching the Church Building Type and Design Sources of a German church architect who had designed many churches and other buildings in Korea. P. Alwin Schmid(1904-1978) had designed 188 Catholic buildings in Korea for 20 years from 1958 to 1978. In his works there are many excellent Catholic ritual buildings. It was caused by his conviction on the theology and the principles of Church Architecture. And His remarkable achievement is affected by the works of Dominikus Bom(1880-1955) and Rudolf Schwarz(1897-1961). Alwin's 5 plan type is relevant to Schwarz' iconographic model, and their approach to 'light' is much the same. But the Character of inner space is the middle of Dominikus Bom and Rudolf Schwarz. His works rotted in the Liturgical Movement had been developed in the line of connection with 20th German church architecture. The works of Dominikus Bom and Rudolf Schwarz played the role of the teacher of Alwin Schwarz.

The purpose of this study is to retrospect the establishment process of specification of modern factory-made traditional Korean roof-tile. Its another purpose is to analyze the specification of watong(瓦桶, a wooden molding frame for roof tile making) which is recorded in the literature of Joseon dynasty. The results of this study are as follows. : First, the specification of modern factory-made Korean roof-tile that currently used was established in 1978. And it did not succeed old traditional specification. Second, in case of construction or repair of main building of palace, it was a principle to use Daewa(大瓦, the big size roof-tile). And Sangwa(常瓦, the ordinary size roof-tile) was used when needed. Also, Jungwa(中瓦, the middle size roof-tile) was used regardless of the size of group building. And Sowa(小瓦, the small size roof-tile) was used in house and wall of royal tomb. Third, it is needed to establish a specification of traditional handmade roof-tile based on the specification of watong through research of the litterateur. So, a standard draft for this was proposed. Finally, one can find the significance that this study has tried to find a specification of traditional roof-tile that can be applied to construction or repair of cultural heritage.

The purpose of this paper is to examine the foundation and subsequent reconstruction years of Unsoo-sa Daeoong-jeon in Busan, especially based on the five records of this building. Moreover, this paper aims to analyze the possibility of the architectural type changes by comparison with nearby Buddhist buildings. The results of this study are summarized as follows. First, Unsoo-sa Daeoong-jeon was built in 1655. Afterward, it had been repaired through five times, but most members of it's wood-framework were found to had been prepared and constructed in 1655. Second, such as the gongpo type, roof type, module system, intercolumnar distance and proportion of intercolumnar distance and column-height, the architectural type of this building is similar to nearby Sinhung-sa Daekwang-jeon. This was because the identical monk-craftsmen carried out the many constructions of nearby temples with their architectural skills at the same period. Third, in particular, the style and created-time of the front gongpos are different from those of the rear gongpos. That is why the front gongpos were replaced when Unsoo-sa Daeoong-jeon was reconstructed in 1771.

The study analyzed on fire resistance of high strength concrete followed by thickness of fireproof plaster board and change of adhesive method. In spalling characteristics after fire resistance test, all four-side covering concretes were left out of testing screens. Thus, serious spalling was happened by exposing their internal reinforcing rods. in partial testing screens, spalling was happened till the internal concrete of main reinforcing rod. Only, temperature history didn't have special differences among changes of adhesive method. However, thickness of fireproof plaster board is very important. Namely, mock member reinforcing 25mm general adhesive + Bending was 583℃ in the highest temperature of surface part and 479℃ in the highest temperature of the main reinforcing rod, which was relatively good temperature history.

This study investigates the field application of surface insulation curing method, which combined double layer bubble sheet(DBS) and thick-curing-material(TCM) for cold weather concreting. According to the test, deck slab, curing only upper section with DBS and TCM, does not make big different temperature history with that, curing both upper and bottom section during daily average temperature 6.5t. It is concluded that combination of DBS and TCM in only upper section can be safely cured in early period of time during cold water concreting. The field test was carried out with this favourable data. The upper deck slab was insulated by combination of DBS and TCM, and the construction was surrounded by tent. in order to protect from outside wind. The test result shows that the lowest temperature of deck slab indicated 6$ ^{circ}C $. It demonstrated that this curing method can resist early frost and save construction cost in the side of management and saving labor cost, compared with previous method. In addition, the column specimen, combined both form and bubble board, exhibited favorable temperature history, due to internal hydration heat insulation effect.
