Modal Parameter Identification of Civil Engineering Structure Based on XGBoost Algorithm

Abstract

In order to prevent the structural problems of buildings and related civil engineering from becoming potential risks, the modal parameter identification method of civil engineering structures is studied based on XGBoost algorithm. First of all, it is necessary to design and extract the modal parameters of civil engineering structures, and then detect civil engineering structures according to the modal parameter identification model, identify the existing problems of the structures, discuss and analyze them, verify the effect of the detection method of civil engineering structures based on modal parameter identification, and make a comparative analysis with the traditional modal parameter identification methods such as SSI. By analyzing the basic principle and algorithm of XGBoost algorithm, this study analyzes the research characteristics and present situation of the method, identifies the implementation and feasibility of modal parameters of civil engineering structures, and provides theoretical basis and data reference for the development of related professions and related industries.
