The aim of this study is to investigate the seismic resistance of dry stone arches under in-plane seismic loading. For that purpose, several numerical analyses were performed using the combined finite-discrete element method (FDEM). Twelve types of arches with different ratios of a rise at the mid-span to the span, different thicknesses of stone blocks and different numbers of stone blocks in the arch were subjected to an incremental dynamic analysis based on excitation from three real horizontal and vertical ground motions. The minimum value of the failure peak ground acceleration that caused the collapse of the arch was adopted as a measure of the seismic resistance. In this study, the collapse mechanisms of each type of stone arch, as well as the influence of the geometry of stone blocks and stone arches on the seismic resistance of structures were observed. The conclusions obtained on the basis of the performed numerical analyses can be used as guidelines for the design of dry stone arches.

Recent earthquakes in Korea caused some damages to stone pagodas and thereby awakened the importance of earthquake preparedness. Korean stone pagodas which have been built with very creative style of material use and construction method are worthy of world heritage. Each stone pagoda consists of three parts: top; body; and base. However each tower is uniquely defined by its own features, which makes it more difficult to generalize the seismic assessment method for stone pagodas. This study has focused on qualitative preliminary evaluation of stone pagodas that enables us to compare the relative seismic performance across major aspects among many various Korean pagodas. Specifically an analytical model for multi-block stone pagodas is to be proposed upon the investigation of structural characteristics of stone pagoda and their dynamic behavior. A strategy for seismic evaluation of heritage stone pagodas is to be established and major evaluation factors appropriate for the qualitative evaluation are identified. The evaluation factors for overall seismic resisting behavior of stone pagodas are selected based on the dynamic motions of a rigid block and its limit state. Numerical simulation analysis using discrete element method is performed to analyze the sensitivity of each factor to earthquake and discuss some effects on seismic performance.

This research is the second attempt to illustrate the phases of ancient Korean architecture through a comparative study of historical materials such as historical ruins, relics, stone remains and art products. Among these the stone stupa (budo), contains many architectural aspects of old times, which give clues to trace the characteristics of the antient Korean structures. The study brings about following results: 1. The pillar employs an entasis technique, and the bracket system (gongpo) consists of cross beams (changbang) and small supporting blocks (soro) thereupon. A type of the bracket arm (chomcha) is also found on top of the pillar. 2. Windows and doors are assumed from the carved features on the stone stupa to be pair-doors which could be folded twice sideways and upwards. 3. There are two types of eaves; the single eaves and the double eaves consisting of a rafter and a flying rafter. 4. The roof has furrows formed by the concave tiles and the convex ones and also the tiles at the edge of eaves. And there are evidences that a variety of small images of animal and human figures were decorated along on top of the eaves.

In case of stone pagoda structures, the various construction types appear, and various damages occur due to exposure to the outdoors for a long time. Such damages can be classified into non-structural damages and structural damages. However, studies for the effects of structural damages on stone pagoda structures are insufficient. Accordingly, this study intends to perform structural modeling and structural analysis according to structural damages of stone pagoda structure, and to perform risk analysis through the fragility curve. So, we expects that this study gives a great contribution to the preservation and maintenance of stone pagoda structures under the various structural damages.

This study is a basic study of the stone cultural landscape resources of Jeju Island with the value of world heritage. It has the ultimate purpose of providing basic resources for the advantages of various Jeju local resources and future conservation and management. Literature research and field survey were conducted to derive the landscape characteristics of Jeju stone cultural resources. and Research for recognition of stone cultural resources and image analysis were performed in parallel. Accordingly I would like to consider the recognition of the Jeju stone cultural landscape held by Korean and Chinese. As a result of the research, Stone is a typical local resource in Jeju, and the greatest feature of the stone was its natural nature. and In the image of the cultural resources of stone, he highly appreciated the image of "Harmonious", "Attractive" and "Unaffected". Recognized Field walls as "Beautiful" and Dolhareubang as "Familiar". And the most preferred stone cultural resources in Korea and China are surveyed in order of Field walls and Dolhareubang, and you can see that there is a difference between them in the evaluation.

Coastal village and Inland village was village in jeju. This study was cultural elements of stone to village in jeju. Memorial Stone and Stone Monument Street, Shrine, An altar of sarificial site for village tutelary spirits, Bangsatap(pagoda), 25 Bongsu(25 beacon fire stations) and 38 Yeondae(38 signaling sites), Hwanhaejangseong Fortress, Grave wall and Horse pasture walls were included in elements of history and culture to village in jeju. An altar of sarificial rite for village tutelary spirits was generally on the a hill near a village, built of Stone wall. Bangsatap(pagoda) was the kind and the size of stone to a location, that expresses the form and the scale. the form of grave wall was the oval or the rectangle, the latter was frequent. Thatched houses in jeju and facilities in a house, Stone wall, Tongsi(pigsty), Paeng namu and A heights of stone, Spring water and Water collected in a depression, Stone Weir, Horse mill and Dodaebul(Old Lighthouse) were included in elements of life and culture to village in jeju. Stone wall has the multiplicity of the size and the building method in the use, the function and the region. The form of Stone weir was the rectangular figure or the curvilinear figure, the section of that was the right triangle or the rectangular form.

Three-story Stone pagodas in Gameunsa Temple site, one of the early staged stone pagodas, has been known as a standard of Silla stone pagodas. A stone pagoda is not only a stone art work and but also a stone architecture. In understanding the stone pagoda it is very important to be approached with technological side in which we can investigate the stone pagoda deeply and as well as to have been approached with art historical view. Also it needs that we should see the stone pagoda in view of structural safety. We can get many high technique from our ancestors who made Gameunsajiseoktap. 1. To reduce any deformation such as relaxation and sinking of members which is caused by a heavy load the members such as the lower tier of the base is made up of the foundation stone and side stone in each, comprising one stone. 2. A special construction method for connection between wall stone and column stone in stereobates was invented. It is to make column stone projected partially and wall stone be caved in that two members should be jointed well. This unique method is not used any longer after the three-story Stone pagodas in Gameunsa Temple Site. 3. In each side upper and lower member are not engaged as the size of roof stones and support stones of roof stones are different. It can be done for a distribution of perpendicular load and a prevention for relaxation of members. 4. It makes sure that to make upper ends of support stones 10mm lower was to be avoid upper loads to it judging from survey in disassemblying east pagoda. It proves that ancestors who made this stone pagoda had a technique to understand the structural matters to make small members as big as possible, not to engage in joint, to avoid in ends of members from upper load.

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.

Culture has long been associated with and advanced by stone as observed in prehistoric dolmen, menhir, megalith monuments, memo-rial stones, and others. The closs association of monuments is seen even in an earlist form of culture and is witnessed to evolve with human history. Korea, with its large quality granite repository, has been active with granite-based monuments in various forms of towers, bridges, and larterns. These stone structures are so abundant throughout Korea that Korea has been called the country of stone tower in Asia. With this historical background, we survey these Korean memorial stone and monuments, found at roadsides, momerial buildings, village entrances, scenic places, schools, sermon halls, public pleasure ground, and other common places. Based on installation orientation, location, and size, a particular emphasis is on the structural value, meaning, beauty, and function of these momnuments coupled with trees, shrubs, water and appropriative landscapes.
