The Damage Survey On The Second Floor Of Yingxian Wooden Tower

Yingxian wooden tower is not only the highest ancient wooden building but also the only timber structure Pavilion-style tower in China.. The tower is a masterpiece of both China and world architectural history, it also has high historical value, artistic value and scientific value. The tower has the history of nearly one thousand years. Both the load-bearing structure of the tower,and the component structure are damaged This was caused by many factors such as eroded by weather,earthquake and lord,etc.The tower is a critical state and need to be repaired.The Damage survey on the second floor of Yingxian wooden tower is the most badly of all the floors. The overall slope of the second floor is very serious. Column and bucket arch have different degrees of damage condition. In this article, the damage condition on the second floor by the scene on the situation of investigation and finite element numerical calculation method for the following work:1. By the corresponding Yingxian wooden tower research literature, summarized the status of Yingxian Wooden Tower.Yingxian Wooden Tower from the material properties, structural characteristics, the damage such as deformation of a summary. The history of the wood tower's restoration and repair programs were discussed, summed up the wooden tower repairs should pay attention to. In addition to the overall damaged the second floor to assess the situation, the main on the damaged column and bucket arch carried out research,2. Through the actual site survey, corresponding to the second floor of the damaged wood tower has done a comprehensive analysis of the situation. In addition to the overall damaged the second floor to assess the situation, the main on the damaged column and bucket arch carried out research. Tables are given to show the deformation and damaged condition of the column and the bucket arch on the second floor. Assessment of damaged level of the component according to the standard.3.Built the element model of the second floor of the Yingxian wooden tower by the finite element analysis software SAP2000,during the process of the model built, reference to the pillar of the tilted column of the second floor.The simplification of the special connection of the wooden tower,tenon-and-mortise work and the bucket arch have been discussed in this article. After the model was built, analyze the stress and strain of the weight load.
