Abstract
En 中文
Building Information Modeling (BIM) technology is instrumental in facilitating the lifecycle management of engineering structures and has been extensively adopted in practical engineering applications. Despite the rich structural information encapsulated within BIM models, the lack of effective data exchange bridges between architectural design and structural analysis stages presents challenges for its application in seismic structural analysis. This paper explores the integration of BIM technology with seismic reliability analysis, proposing a BIM-based seismic reliability assessment framework for Reinforced Concrete (RC) structures. Leveraging the RevitDynamo platform, we extract geometric and material information inherent in BIM models to serve as foundational data for OpenSees analysis models. A custom program named BTO (BIM to OpenSees) is developed using Python to comprehensively configure element types, material constitutive models, load information, and analysis types for OpenSees simulations. Then, seismic reliability assessment of RC structures is conducted using the Fractional Exponential Moments-based Maximum Entropy Method (FEM-MEM) based on the obtained results. The reliability results are subsequently visualized within the BIM model through Dynamo. Two case studies, involving RC frame and frame-shear wall structures, demonstrate the feasibility of this integrated approach for elasto-plastic seismic analysis.
