Mechanical Performance Analysis of Bridges Based on Improved Damage Algorithm and Intelligent Simulation

Top load-bearing arch bridges are widely distributed in China because of their beautiful structure, harmony with the surrounding environment, and excellent seismic performance. With the development and development of the national economy and technology, the span of the arch bridge continues to increase. Considering the material nonlinearity of the arch bridge, the shrinkage of concrete and the influence of temperature, the arch bridge will become very complicated. In addition, especially in the construction process, the design process of the long-span top arch bridge is complex, the construction process is numerous, and the construction quality is very high. In order to ensure the safety of the bridge structure during the construction process and the bridge operation process. The purpose of this paper is to study the mechanical performance analysis of bridges based on improved damage algorithm and intelligent simulation. This paper analyzes the concept and characteristics of intelligent simulation, the basic composition of intelligent simulation system, the dynamic analysis theory of CFST arch bridge and the calculation theory of static performance of CFST arch bridge, and the experimental results are obtained. The empirical analysis results show that after using the improved damage algorithm and intelligent simulation, the mechanical performance of traditional bridges has been greatly improved, and we conducted a questionnaire and found that more than 88% of people felt that the analysis of the mechanical performance of bridges was applied to the improved damage algorithm. And intelligent simulation, found that the design efficiency has become high.
