Abstract: Using wavelet and bat algorithm to study the damage identification of frame structure.Firstly, solving the curvature mode of the damaged structure by finite element analysis. Secondly, by using continuous wavelet transform, the curvature mode is processed to obtain the wavelet coefficient figure. The damage position of the structure was identified by the position point of the maximum modulus in the wavelet coefficient figure.Finally, constructing the objective function based on the frequency and mode shape of the structure and using the bat algorithm to solve the objective function, the degree of structural damage is obtained.A two-stage structural damage identification method based on wavelet and bat algorithm was established. Using this method to analyze one - floor one - span and two - floor two - span frame structure.The results showed that the combination of wavelet and bat algorithm could effectively identify the damage location and damage degree of the structure.Abstract: Using wavelet and bat algorithm to study the damage identification of frame structure.Firstly, solving the curvature mode of the damaged structure by finite element analysis.

Abstract: Xinjiang is an earthquake-prone area. Historic earthquake disasters show that the construction disasters in villages and towns caused by earthquakes are serious, which directly affects the lives of local residents and also brings huge economic losses. In view of the earthquake disaster of traditional rural dwellings in southern Xinjiang, this paper carries out an investigation and analysis. Based on the research and analysis of seismic measures for traditional dwellings, this paper puts forward strategies and concrete structural measures to strengthen the seismic performance of different types of traditional dwellings in rural areas of the region, and draws out specific structural design and schematic diagram. The research results have a certain reference value for the Rural Revitalization and beautiful rural construction in order to improve the seismic performance of different types of traditional rural dwellings in this area.Abstract: Xinjiang is an earthquake-prone area.
