Precast Structure Connection Node Reliability Analysis Based On Improved Imperial Competition Algorithm

Precast concrete structure is an important way to realize building industrialization.It is becoming the mainstream of the development of construction industry.The connection nodes between components are very important for ensuring prefabricated structure to perform predetermined functions.In view of this,it is of great theoretical and practical significance to use the theory of system reliability to guide and optimize the connection nodes with efficient optimization algorithm.The original Empire competition algorithm(ICA)is improved to make it adapt to the optimization problem with higher nonlinearity and improve the efficiency of the solution.The improved Empire competition optimization algorithm is used to analyze the reliability calculation process of the assembly structure dark bull leg node,and to expand the application scope of the algorithm,and the reliability of the assembled concrete structure node is reliable.The main work of this article is as follows.This paper briefly introduces the development process of the assembly structure and the status of the research at home and abroad,and discusses the related research contents of engineering reliability and imperial competition algorithm.The finite element software ABAQUS is used to model and analyze the reinforced concrete dark bull leg,to verify the correctness of the formula derived from the theory and to apply Latin hypercube.Sampling method,quantum behavior and information entropy are used to improve the original ICA algorithm,and test function test is used to improve the effectiveness of the algorithm,and the improved algorithm is applied to the reliability solving process.The reliability index of the assembly frame structure connection node is modeled and solved,and the result is compared with the Monte Carlo sampling method.The proposed method improves the efficiency and precision of the solution compared with the traditional method,and proves that it is of practical significance to combine the improved Empire competition algorithm with the reliability analysis of the assembly frame structure.Summing up the current research results,pointing out the shortcomings of the research work at the present stage,and discussing the development trend of related contents.
