The Deformation Of Column Grid And The Stability Analysis For The Yingxian Tower

Chinese historic buildings not only are the important part of Chinese ancient civilizations, but also the world cultural heritage, which have the highly historical, artistic, science and cultural value. In China, the timberwork building has a long history and gradually forms its unique style characteristic, with continuous improvement and perfect. These are both the scientific and sapiential crystallization of the ancient working people and the architecture model of ancient Oriental art.Sakya tower in Buddha palace temple is commonly called as Yingxian wooden tower. It is the most remote and ambitious timber in our country and even in the global, being a masterpiece in the building history of the world. The Wooden Pagoda undergoing more than 900 year vicissitudes of life, stands in Shanxi Province. But some unsafe factors,such as the corrosion by the long-term wind, rain, wind, war and earthquake and lumber itself dead load and aging, cause the phenomenon of the whole settlement and deformation, the component distorted, splitting, broken and whole load imbalance, which seriously affected the life span of the temple. In accordance to the technical code for maintenance and strengthening of ancient timber buildings, the wooden tower is defined as the four architecture initially and urgently need repair and protect. The wooden Pagoda has been list the important projects of historic preservation in the Layout of Culture Development in 11th five-year.The research objects of this article are the pillars in the Yingxian wooden tower, which are the main bearing component. By data access, field survey, the finite element numerical calculation method, the following aspects have been completed.1、Through the collection, consult the material related the pagoda,combining with field survey, the writer makes a strengthening understanding its history, introduce the two kinds existing maintenance schemes, and detailed analysis main influencing factors of the damaged structure of the wooden temple.2、According to the field investigation, combining with the existing material, the writer makes statistical analysis about the tilt and distortion of the temple columns in each layer. Comparative analysising the original data and the measured value, according to the stress state, deformation law is get.3、The second-layers finite element model is established in the finite element software ANSYS. In the affection of vertical load and dead load, forehead and other compression members are about to yield, and the stability of column net largely fall. All of these are the results of the static and stable performance analysis, which provides beneficial references for the maintenance of fu-gong temple.4、According to the principle of the historic protection, the rectification method of the steel netting resetting is suggested. The first step is to control the tilt intensified trend of the wooden temple. This method is simple, feasible and safety and reversible.
