Research On Civil Engineering Structure Test Information Management System Based On BIM

With the deepening of the test content,the technical difficulties involved in the test are further increased,and the investment of the required test equipment,materials and manpower is also increased,resulting in a large number of test data information,however,the current experimental information management mode has exposed many problems,such as information "island",information loss,low degree of visualization and so on,which can not meet the increasing needs of experimental information management.BIM,as a popular concept in the civil engineering industry,its core lies in the integration,sharing and transmission of information,which brings a new management idea and way to the civil engineering structure test information,and can provide strong technical support for the scientific decision-making of all participants and the successful completion of the test objectives.This paper takes the civil engineering test information as the research object,introduces the BIM concept into the test information management method,and deeply studies the civil engineering structure test information management system based on BIM.The research contents and achievements of this paper are as follows:(1)a BIM based information management method for civil engineering structure test is proposed,which means that all participants of the test take BIM test information model as the carrier,and pass BIM test information management system to efficiently transfer and share the BIM information data of the test;(2)This paper constructs a BIM based civil engineering structure test information management framework,which consists of five layers: storage layer,resource management layer,functional logic layer,business appearance layer and presentation layer;(3)Develop the general interface,database and parameterization of the civil engineering structure test information management system to create the test information model,and provide the realization ideas and core codes of the key functions of each module;(4)Taking the performance test of hinged shear wall with BRB as an example,the test information management system is applied in the three stages of test plan and preparation stage,test implementation stage and test analysis and summary stage to verify the feasibility of the test information management system and summarize its role in test information management.The research of this paper provides a way to establish information transmission and sharing mechanism in the process of test information management,which can effectively solve various problems encountered in the traditional test information management mode,and promote the development of information technology in civil engineering structure test information management,so it has important application value and research significance.
