A Research On The Influencing Factors Of Knowledge Sharing Behavior Of BIM Content Library Users

BIM technology realizes the 3D parametric modeling of building projects by combining the building components with real parameters,which are managed by "content library".BIM content library can store and manage building components and make them to be repeat used,which improves work efficiency.At present,the content library of BIM software comes with limited resources,some of which are not consistent with the design standards,so the construction of the online BIM content library is important to meet the needs of the industry.BIM content library is a platform to store and manage the BIM component,which can be created and shared by users.The promotion of the users' knowledge sharing can develop the BIM content library,and the premise is to understand the antecedents and consequences of knowledge sharing behavior.However,research in this field is limited.This paper intends to explore the factor which affects the knowledge sharing behavior of BIM content library users,make clear of the antecedents and consequences of knowledge sharing behavior,locate the key points that affect the users' knowledge sharing behavior,lay the foundation for the promotion of sharing behavior,provide theoretical basis for enriching the BIM content library,and improve the work efficiency and the development of BIM technology.The research takes the theory of reasoned action as framework and identifies the factors that affect the knowledge sharing behavior of BIM content library users and constructs the theoretical model based on the relevant literature and expert interviews.Then the author designs the questionnaire based on maturity scale and expert interviews,and makes survey for the BIM relevant practitioners.After reliability analysis and validity analysis for the data,the research verifies the hypothesis through the correlation analysis and multiple linear regression analysis.The result of empirical analysis shows that the BIM content library website user's willingness of knowledge sharing depends on their attitude towards knowledge sharing behavior and subjective norms,while the attitude towards knowledge sharing behavior depends on the incentives of BIM content library website,user's trust in others and the website,the beneficial relationship between users and their sense of self-worth,subjective norms depends on users' sense of self-worth and the website atmosphere.
