The bracket sets which are supporting the weight of the roof, has to meet both requirements which are structural functions and act as an ornamental element. Therefore the bracket sets differ in many types from time and space and has done an important role in the history of architecture with many studies being presented. The first form of the bracket set has been found in the bronze table relics in zhong shan wang ling (中山王陵). Through the Eastern Han dynasty (A.D. 25-220) it became more specific in the shique (石闕) and huaxiangshi (畵像石) in the Han dynasty (206 B.C.-A.D. 220). Afterwards, as Buddhism was introduced to China, the bracket construction techniques shown in the Mogao Caves, Yungang Grottoes, and Longmen Grottoes has given much help for understanding the building techniques of wooden architecture. Especially the Xia-ang structure seen in the Mogao caves shows a vast development in wooden structure and a typical building would be the main hall of Fo Guang Shan monastery in Mt. Wutaishan from the Tang dynasty (A.D. 618-907). This accumulated techniques is inscribed in the 'Ying Zao Fa Shi (營造法式)' wooden structure designs which was published during the Northern Song dynasty (A.D. 960-1127) and many buildings were constructed following this technique after the publication. During this period, it is assumed that Baek-jae (B.C.18-A.D.660) in the Korean peninsula also used the Xia-ang technique, but there havn't been many studies on this field. In this thesis it is introducing the development of the building techniques and structural features of the Xia-ang wooden architecture during the Tang and Song dynasty.

This paper studies the style emergence of Liujin Dougong in the ancient Chinese architecture. Dougong is the bracket set of the ancient Chinese wood structural architecture, and Liujin Dougong is one of the late styles of Chinese Dougong. It emerged in the period of the Ming Dynasty and has been installed in imperial palaces and imperial temples till the late period of the Qing Dynasty. Through the long term field survey and documental investigation, this research found out the some prototypes of Liujin Dougong among the earlier Xia-ang style Dougongs in the Song and Yuan Dynasty architectures. The symptom of style change appeared in the bracket composition. In the beginning, because Shuatou, the horizontal member just on Xia-ang was needed to be fixed to the inner main structure system, it was changed to the diagonal member and replaced Xia-ang. It brought continuous changes, the other horizontal members of Dougong also began to change to the diagonal form. And in accordance with these compositional changes of Dougong members, the decoration of inner parts also began to change. This paper analyzed every step of the compositional and decorative changes from Xia-ang Dougong style to Liujin Dougong style. In the addition, it also proposed the typical model of Qing style Liujin Dougong of which tail end is not placed on the beam and is just placed under the purlin, based on the its own research and analysis.

An accurate calculation of the stochastic wind field is the foundation for analyzing wind-induced structure response and reliability. In this research, the spatial correlation of structural wind field was considered based on the time domain method. A method for calculating the stochastic wind field based on cross stochastic Fourier spectrum was proposed. A flowchart of the proposed methodology is also presented in this study to represent the algorithm and workflow. Along with the analysis of regional wind speed distribution, the wind speed time history sample was calculated, and the efficiency can therefore be verified. Results show that the proposed method and programs could provide an efficient simulation for the wind-induced structure response analysis, and help determine the related parameters easily.
