In this paper, the structural performance of Suwon Hwaryeongjeon Unhangak, a representative traditional timber structure in the late Joseon Dynasty, was evaluated. Based on the structure composition of Unhangak, an analysis model was elaborately constructed with Midas Gen, a 3-dimensional structural analysis software. The safety and serviceability of major structural members were evaluated by static analysis, and the dynamic behavior characteristics were evaluated by eigenvalue analysis. Most of the members satisfied the safety and serviceability standards with a margin; however, the bending stress ratio in the oemogdori exceeds the standard by 20.7%, so it is considered that long-term monitoring is needed for this member. The natural period of Unhangak is 1.079 seconds, which is slightly longer than traditional timber buildings of similar scale. In particular, it is analyzed that torsional movement occurred in the secondary mode due to the influence of the rear masonry firewall.

In this study, organic materials in Dancheong specimens were analyzed to establish a Dancheong preparation method in Unhangak Hall of Hwaryeongjeon Shrine, Suwon. IR and pyrolysis/GC/MS were applied to a Zuhong specimen and a gilded one. The IR spectra showed absorption peaks corresponding to C-O, C=O, OH, although they were different from those of animal glue, Asian lacquer, and drying oil. The Pyrolysis/GC/MS after the on-line methylation revealed Asian lacquer-derived components, such as methyl 7-(2,3-dimethoxyphenyl)heptanoate, and drying oil-derived components, such as nonanedioic acid, dimethyl ester. Based on these results, we estimated that Asian lacquer and drying oil were used in the Dancheong preparation. Small amounts of 3-methyl-1H-pyrrole were also detected, which could possibly originate from animal glue. The radiocarbon age of the specimens appeared to be between the late 17^th to the early 20^th century. This study potentially reports the first case of Asian lacquer detection in a Dancheong specimen in Korea.

This study is the consideration about Hwaryeong-Jeon that enshrines Joseon Dynasty 22nd king Jeongjo's portrait of a king. Suwon's Hwaryeong-Jeon that accompanied a portrait and performed ritual ceremonies had several formalities and ceremonies which are connected with rituals. therefore, we will try to examine what relation between arrangement of building and plane composition had. And through this, it is thing to observe construction special quality that Hwaryeong-Jeon has. Joseon Dynasty's young-jeon (a hall where the royal portraits are kept) is retaining each other different state according to construction age every moment. Hwaryeong-Jeon among Joseon Dynasty's a hall of royal portraits is the construction form which is equiped well and is known for keeping the form well from the foundation to now And this building is evaluated as the standard form of early part young-jeon building of 19th century. Especially, Hwaryeong-Jeon shows the typical ritual equipments late Joseon Dynasty and at the same time has all kinds of characteristics which only we can find at Hwaryeong-Jeon. Namely, Hwaryeong-Jeon is the building which brings the design concept of the hall of royal portraits to completion as the building which enshrines single portrait of a king. After all, Hwaryeong-Jeon is evaluated as the building which can pass excellent form of late Joseon Dynasty, the hall of royal portraits building just as it is. Therefore, as I study its own style, I expect Joseon Dynasty's mind that enshrined the portrait of a king elaborately to be revealed.
