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 this paper, the wind-induced response of Jiayuguan wooden building (world cultural heritage) in Northwest China was studied. ANSYS finite element software was used to establish four kinds of building models under different working conditions and carry out modal analysis. The simulation results were compared with the field dynamic test results, obtaining the model which reflects the real vibration characteristics of the wooden tower. Time history data of fluctuating wind speed was obtained by MATLAB programming. Time domain method and ANSYS were used to analyze the wind-induced vibration response time history of Jiayuguan wooden building, obtaining the displacement time history curve of the structure. It was suggested that the wind-induced vibration coefficient of Jiayuguan wooden building is 1.76. Through analysis of the performance of the building under equivalent static wind load, the maximum displacement occurs in the three-story wall, gold column and the whole roof area, and the maximum displacement of the building is 5.39 cm. The ratio of the maximum stress value to the allowable value of wood tensile strength is 45 %. The research results can provide reference for the wind resistant design and protection of ancient buildings with similar structure to Jiayuguan wooden tower.

Based on the shaking table tests of a 1:3.52 scale one-bay and one-story ancient wooden structure, a simplified structural mechanics model was established, and the structural state equation and observation equation were deduced. Under the action of seismic waves, the damage rule of initial stiffness and yield stiffness of the joint was obtained. The force hammer percussion test and finite element calculations were carried out, and the structural response was obtained. Considering the 5% noise disturbance in the laboratory environment, the stiffness parameters of the mortise-tenon joint were identified by the partial least squares of singular value decomposition (PLS-SVD) and the Extended Kalman filter (EKF) method. The results show that dynamic and static cohesion method, PLS-SVD, and EKF method can be used to identify the damage degree of structures, and the stiffness of the mortise-tenon joints under strong earthquakes is reduced step by step. Using the proposed model, the identified error of the initial stiffness is about 0.58%-1.28%, and the error of the yield stiffness is about 0.44%-1.21%. This method has high accuracy and good applicability for identifying the initial stiffness and yield stiffness of the joints. The identification method and research results can provide a reference for monitoring and evaluating actual engineering structures.

The main buildings of the important Buddhist temples - the pagoda, the Buddhist sanctum, the lecture hall - was surrounded by the cloister until Koryo Dynasty. And the Buddhist sanctum was located the center. It meant that the Buddhist sanctum was important building. It is very important thing that we understand the usage of the interior space because the architectural space consists of the unified space by the organic function of the interior space and the exterior space. But there is not so much the study on the interior space of the Buddhist sanctum. So, the purpose of this study is to understand of the interior space of the Buddhist sanctum in Ancient and Medieval Times. Till now, it was impossible that the Buddhist monk or the General public entered the Buddhist sanctum in Ancient and Medieval Times because they regarded the Buddhist sanctum as the place of sacrosanctity and the floor was finished by bricks. But, we saw that they could enter the Buddhist sanctum. Of course the floor of the Buddhist sanctum was finished by bricks, but they spread mats on the floor, took off his shoes in the interior space and used the furniture for sitting on. The plan of the Buddhist sanctum was designed by the process of the ceremony and the way of the enshrinement of the Buddhist statues because it is the place to enshrine the Buddhist statues. They performed the ceremony like as pray, worship, offer food to Buddha, HaengDo - an act to turn round an object of worship - and so on in the interior space of the Buddhist sanctum.

In order to study the failure mode and seismic behavior of the interior-joint in steel traditional-style buildings, a single beam-column joint and a double beam-column joint were produced according to the relevant building criterion of ancient architectural buildings and the engineering instances, and the dynamic horizontal loading test was conducted by controlling the displacement of the column top and the peak acceleration of the actuator. The failure process of the specimens was observed, the bearing capacity, ductility, energy dissipation capacity, strength and stiffness degradation of the specimens were analyzed by the load-displacement hysteresis curve and backbone curve. The results show that the beam end plastic hinge area deformed obviously during the loading process, and tearing fracture of the base metal at top and bottom flange of beam occurred. The hysteresis curves of the specimens are both spindle-shaped and plump. The ultimate loads of the single beam-column joint and double beam-column joint are 48.65 kN and 70.60 kN respectively, and the equivalent viscous damping coefficients are more than 0.2 when destroyed, which shows the two specimens have great energy dissipation capacity. In addition, the stiffness, bearing capacity and energy dissipation capacity of the double beam-column joint are significantly better than that of the single beam-column joint. The ductility coefficients of the single beam-column joint and double beam-column joint are 1.81 and 1.92, respectively. The cracks grow fast when subjected to dynamic loading, and the strength and stiffness degradation is also degenerated quickly.

Paju Mok was the local administrative office of the Joseon Dynasty as the administrative and transportation center of western part of Gyeonggi-do and used as a Haenggung when the king visited the royal tomb of the Joseon Dynasty. Paju Mok Government Office was adjacent to Uiju-ro, which connects Hanyang and Uiju in the Joseon Dynasty. Paju Mok Government Office is an important place in the northern part of Gyeonggi, where the king stayed when he visited the Jereung, Hulleung which are located in the northern part of Hwanghae Province and Paju Yeongreung and Jangneung, Paju Mok Government Office was maintained until the 1900s. After the Japanese colonial Period, Government Office buildings are used for other purposes, and their function as a Government office is impaired. In addition, most of the buildings disappeared due to the Korean War, and now the state of Paju Mok Government Office was lost. In order to restore the lost Paju Mok Government Office, it is necessary to study the composition of Government Office, such as the place where Paju Mok Government Office is located and major buildings. Therefore, if you find out the location Estimation, spatial composition and size of Paju Mok Government Office by analyzing and analyzing ancient documents and ancient books related to Paju Mok Government Office, and the topographic map and cadastral map and land survey department during the Japanese colonial period, you can be used as basic data when restoring Paju Mok Government Office.

In this paper we present the result of investigations pertaining to the buckling strength of Zelkova Serrata (Elm-like) tree column with entasis at the Muryangsujeon in Buseoksa-Temple, Korea. Wooden columns with entasis had been used in the construction of ancient architectural buildings in Korea. It was not known why did they design columns with entasis of the buildings. It is just presumed that the reason may be the compensation of optical illusion, aesthetics, and/or structural safety. The question is not answered even today and it may not be possible to answer clearly and easily. In the paper, the buckling analyses are conducted on both of the wooden column with entasis and the prismatic wooden column by the successive approximations technique and the finite element methods, respectively. The results of analyses are compared and discussed.

This paper analyzed the characteristics of ancient villages in Hongcun and the method of resetting the preservation area for the preservation of the changed historical and cultural space in Hongcun through the process of change. To this end, the current status of preservation areas and utilization areas in the village was identified through ancient documents, old paintings, policy materials, and interviews related to the village, and through this, the problem of resetting the preservation area was examined. As a result, the following conclusions were drawn. First, Hongcun is a village built under the influence of Confucianism, Buddhism, and Taoism, and the spatial organization was created according to the hierarchy of Confucianism. As a result, it was possible to inherit and preserve the heritage of ancestors even though the central government did not preserve it. Second, the concept of preservation in a limited sense has been applied as Hongcun has been recognized as a cultural heritage that has been passed down since ancient times, but the Great Leap Forward and the Cultural Revolution brought about changes in the village space. Since then, ancient buildings, water systems, and forests have been preserved through regulations on new construction and expansion of a building with the Hongchon preservation plan, but the development within the preservation area is underway due to changes in the lives of original inhabitants, which were followed by continued development pressure and reform and opening. Third, the original inhabitant of ancient villages had a high perception of the value of the heritage, but they demanded the preparation of measures to improve living conditions and create profits, and the active use of villages for this. Fourth, the forest consisting of old trees is being restored, but the gardens in the old house are showing a phenomenon that the garden space is reduced or transformed for use. The bridges and parking lots were newly built in the southern area, which was extended from the western area, the original entrance to the ancient village, resulting in changes in the existing entrance. This was found to be the primary cause of the spatial change of the ancient village, as the road system was modified to make it convenient for tourists to enter and exit. Fifth, the existing preservation area should be reset and preserved by resetting the preservation route centered on Wolso(half Moon Pool), while the surrounding area should be set as a direct and indirect experience space, and according to the hierarchy of each space, the utilization should proceed while the preservation is carried out by crossing the preservation and the utilization.

Alberti's De re aedificatoria is the earliest case in the history of Italian Renaissance architectural treatises dealing with recovery of antiquity through textual and archaeological pursuits. The key source of the Renaissance theoreticians was Vitruvius' De architectura. However, Alberti was keenly aware of inaccuracy and Hellenization of Latinity in this classical text, and tried to compensate them in his own treatise. Furthermore he claimed a reformed discipline of the architects as well as the patrons, and prescribed how future buildings and cities should be built, based on the proper authority of ancient architecture in proper and intelligible Latin. Such an adaptation of classical usage in order to reestablish a modern norm preceded in his earlier work Momus, a satire on the contemporary Italian society of his own by following the model of Lucian. Alberti's suggestion of proper government in Momus's phrase was expanded in De re aedificatoria, for he consider the buildings are subject to the rules of morality and public interests. He proclaimed that the nature of beauty is the reasoned harmony of every part within a body, and architectural beauty also lies on the harmonized arrangement of all the elements within an individual building and of all individual buildings and facilities within a city. For the architects to execute this task, he formulated the concept of lineanenta, the form derived from the mind in order to prescribe the proper place, numbers, scale, and orders for whole building structure. It is the future oriented city-plans and building designs to serve the public interest and the good of all the individual citizens who make up the City-State that Alberti pursued in his treatise.
