This research aims to illustrate the structure of the ancient Korean wooden buildings by a comparative study of the historical resources such as stone remains, wall paintings historiographies and excavations. As stone pagodas are the most typical stone remains, I selected for analysis some stone pagodas which contain architectural elements and results of the study are as follows: 1) The number of stories and structural modes of the base stone part show the wooden architectural aspects: they have one or two stories and their base part is constructed in the mode of assembling rectangular stones. 2) The body of the pagoda contains such architectural elements as pillars, door and windows, crossbeams, balcony, bracket sets. 3) The roof of the stone pagoda contains such architectural elements as eaves, roofs and modes of stone assembling. The results inferred through this research could be of help for further comparative studies with the other secondary materials by providing basic knowledge for it.

The Mireuksaji stone pagoda was built foundation in the reign of King Moo (AD 639) in the Baekje Kingdom of ancient Korea. The stone properties of the pagoda were quarried from Mountain Mireuk, which are medium to coarse-grained light gray biotite granite formed during the Jurassic, and are composed of quartz, feldspar, biotite, muscovite, apatite and allanite. It was strong relatively but became weak from prolonged weathering, and as a result its durability fell to $883kgf/cm^3$ (moderate weathering degree). In the process, cut-off (31%), deletion (57%) and crack (44%) occurred in foundation materials by the influence of bending, shear and compressive force. Hereat, the original materials were treated through a preservation process. As a result, approximately 74% of original materials have been able to be reused, inclusive of 55 materials that were to be partially replaced by new stones. On the other hand, it is inevitable that the other 26% including exterior stones and support-based stones have to be partially replaced by new stones. It implies that there is a need to find stones that are identical or similar to those of the pagoda. Consequently, a lithological study was conducted on stones in quarries located in Iksan and an investigation was made into their properties. The results showed that stones in the Hwangdeung area were most similar to those of the pagoda mineralogically and their properties were most stable.

The west stone pagoda of Gameunssji temple site (National Treasure No. 112) has been damaged mainly by fracture, exfoliation and granular disintegration. In this study, the source area of the rocks using the west stone pagoda was examined in terms of petrological feature, magnetic susceptibility, and ${\gamma}-ray$ spectrometer. The stones include abundant crystal fragments of biotite, quartz and feldspars in the fine-grained matrix; they are petrographically discriminated to vitric-crystal tuff or crystal tuff. Measured magnetic susceptibility values are of from 10 to 20 $({\times}10^{-3}\;SI\;unit)$. From the ${\gamma}-ray$ spectrometer measurement K, eU, and eTh contents of the stones are about 3%, 0 to 8ppm, and 9 to 18 ppm, respectively. These features are used as indicators to presume the source area of the stones. Comparing the petrographical and chemical characteristics between the stones of the west stone pagoda and the country rocks near the Gameunsaji temple site, it is suggested that the most similar country rock to the stones could be dacitic volcanic rocks of the Beomgokri group in the Waeup basin. The Beomgokri group is lithostratigraphically divided into Waeupri tuff, Yongdongri tuff and Beomgokri volcanic rocks. Among the three rocks, the crystal tuff of the Beomgokri volcanic rocks seems likely to have been the source rock of the stones of the west stone pagoda.

Korean pagodas were constructed in the shape of a wood pagoda, brick pagoda, stone pagoda, etc. On the other hand, the currently remaining traditional pagodas are those having nonflammable materials, such as brick, stone, etc. Compared to the stone pagoda, there is data regarding brick pagodas, but there is little literature data on how to construct these pagodas. This appears to be because there are relatively few Korean brick pagodas currently remaining, they are locally restricted, the material limit is not overcome, pagoda's historical and regional problems have not been analyzed, and pagoda construction is centered on pagoda construction. Therefore, this study examined the local cultural characteristics on the construction of brick pagodas. As a result, cultural exchange between Korea and China was performed through the silk road and there was a marine route for cultural exchange. Such exchange was shared with the East Asia area as well, which can be found by comparing remains at related areas. Exchange with China can be mentioned as the selective exchange of local powers as well as blind learning. Second, brick pagoda were constructed in Korea because of the good quality soil easily. Uisang's Hwaeomjong was negotiated with the main power not agreeing with Buddhism, which was popularized and the local power. Third, brick pagoda construction was influenced by negotiation related between Balhae and Silla, in which the ethnic influence was locally affected and could be mentioned as being a culturally selective result transferred from China. As a result, brick pagodas can be oriented by forming a unitary state rather than a small country within China's influence range as well as cultural transfer through the silk road.

In the middle of the 8th century, we met the new high-rise building, the 7th storied wooden pagodas in 'Kokubunji' in Japan. I tried to analyze and study this building to show how the wooden pagoda had changed itself because of appearance of new style. The conculusions are as follows; 1. The construction of the foundation was mainly composed namely 'Panchuk'. It was proceeded by two ways. One is the earthen-digging, laying foundations named 'Gulkwangpachuk' and the other is simply laying foundation named 'Jisangpanchuk'. In that period, due to the progress of the technique, we assumed that the main stream is 'Jisangpanchuk'. 2. The elevation of base was mostly the single foundation from archaeological study. The material was stone. The middle case of pagoda had the base of tile-roofed. We knew the just one pagoda had the base of brick, but that was not main stream. 3. The new device had appeared in the central base stone. It was the stone point. But in that period the existing method, a hole style and the new style was used in the central base stone. This fact is showed that the central government was not hold the reigon(it names 'Kook') in the respect of the technique. 4. The plan scale is classified of 3 group. As a result, the first body is larger, the main-unit and the sub-unit is a equal unit. But smaller, the length of main-unit is longer than the one of sub-unit. And the very small pagoda was build in that period.

The Muryangsa temple five-storied stone pagoda (Treasure No. 185) was geographically located in the area of the Baekje Kingdom. The architectural style of the Muryangsa temple five-storied stone pagoda is the pagoda at the early Goryeo Dynasty that was succeeded technique of the Baekje Kingdom and form of the Shilla Kingdom. Because this pagoda is located outside during old time that it received serious petrological and biological weathering in rock blocks and occurred the center subsidence in the upper capstone. This study executed ground stability interpretation in order to know what central subsidence in the upper capstone occurred for soft ground. The ground stability interpretation used seismic survey, electrical resistivity survey and GPR survey by non-destructive method. As the result, the ground appeared in the condition which is good. Specially, high resistance zone appeared from electric resistivity survey which come to seem with ground reinforcement harden. Consequently, central subsidence condition in the upper capstone is not by the instability of ground, and is judged with the thing by the structure instability in rock blocks over the upper capstone. This will be applied basic data with the long-term monitoring or preservation countermeasure of the pagoda.

This study was carried out on scientific conservation treatment based on material characteristics, provenance interpretation, and deterioration diagnosis for seven-storied Jungwon Tappyeongri stone pagoda in Chungju. As a result, main rock of the pagoda is biotite granite with magnetite-series (average $5.86{\times}10^{-3}$ SI unit), containing partly basic xenolith, pegmatite veinlet and feldspar phenocryst. As a result of the provenance presumption of the host rock, a rock around the Songgang stream was identified the same origin. Therefore the rock is appropriate for materials of the pagoda restoration. The deterioration assessment suggested that the pagoda was seriously exfoliated (2.7 to 5.5%), discolored (39.8 to 58.9), and contaminated with repair materials (3.5 to 9.4%), and bioorganisms (19.3 to 24.4%). Accordingly, conservation treatment was carried out based on preliminary investigation for stable conservation of the pagoda. Overall processes were sequentially proceeded by restoration of the replacement stone, cleaning, joining and consolidation. This study sets up an integrated conservation system from preliminary investigation to conservation treatment of the pagoda. Also, the study will contribute for establishing the future-oriented customized conservation treatment.

The constituting rocks of Multi-storied Round shape stone Pagoda of Unjusa Temple are lithic tuff and rhyolite tuff breaccia which show green or grey and also rock fragment with poor roundness are present in the structure. lithic tuff is composed of feldspar and quartz which are glassy texture and cryptocrystalline and also micro crystalline are scattered. phenocryst quartz and feldspar in the substrate composed of feldspar and opaque minerals are found in rhyolite tuff breaccia. dust, exfoliation, cavity, fracture and crack are observed in all the stone of the pagoda and the result of Infrared Thermography shows partial inter cavities have developed severely which may cause further exfoliation. In addition, a great deal of various grey, green, and yellow brown lichen as well as bryophyte are present at the upper part of eastern and western roof stone located above the third floor. Discolors remarkably shown at stereobate and roof stone are identified as inorganic pollutants such as manganese oxide, iron oxide and iron hydroxide. The stone of the pagoda of the Chemical Index of Alteration (CIA) and the Weathering Potential Index (WPI) are 55.69 and 1.12 respectively and this corresponds to a highly weathered stage. The measured values, average ultrasonic velocity 2,892m/s, coefficient of weathering 0.4k and compressive strength $1,096kg/cm^3$, suggest that the rock strength and durability are weakened.

Multi-layered stone masonry monuments, such as stone pagoda can be modeled as a multi-degrees of freedom system. The dynamic behavior of these structures are mainly influenced by contour condition of contacting surface of stones. In this case the mass of the system can be easily estimated, mean while the estimation of stiffness at junction is not simple. In this paper a method for estimating the spring constant at the contacting surface of stone in proposed. This paper describes a method of computational modelling technique for structural analysis of stone pagodas using measurement of natural frequency and eigenvalue analysis. For this purpose Five story stone pagoda in Cchongnimsa site was selected as a model.
