چکیده مقاله
The integration of demountable high strength friction grip bolts HSFGB within prefabricated steel concrete composite beams presents an innovative approach to sustainable construction However, the lack of standardized design guidelines impedes its wider application This research aims to perform a reliability based analysis to determine the flexural resistance factor p for these beams, which is crucial given the incorporation of the shear connector resistance factor within AISC specifications A validated three dimensional finite element model is employed to simulate beam behavior, and a sensitivity analysis investigates the influence of key parameters on flexural capacity The flexural resistance factor is assessed across varying degrees of shear connection, ensuring an acceptable safety margin Statistical analysis of push out test data quantifies connector variability and uncertainty Results indicate that the flexural resistance reduction factor is significantly dependent on the degree of shear connection Notably, the application of AISC recommended factors for welded connectors proves to be non conservative for these demountable systems
