RESEARCH ON THE SHEAR STRENGTH OF REINFORCED CONCRETE INTERIOR JOINT BASED ON BAYESIAN THEORY

摘要：

　　Reinforced concrete (RC) interior joint shear strength models are constructed using an experimental database in conjunction with a Bayesian parameter estimation method.The experimental database consists of RC beam-column connection test subassemblies that were subjected to quasi-static cyclic lateral loading and experienced joint shear failure.One type of interior joint shear strength models are developed.Bayesian methodologies for model construction Gardoni et al.(2002) introduced a Bayesian methodology for developing probabilistic shear capacity models of RC joints based on experimental observations.The probabilistic models were constructed by correcting the biases in existing deterministic models and by quantifying the remaining errors.The model considers all possible influence parameters on joint shear strength.And the model as the advised model for design contains those parameters left after a step-wise process that systematically identifies and removes the least important parameters affecting RC interior joint shear strength.Finally,Better agreement between experimental results and advised model results is identified by comparison with the current ACI 352R-02 RC joint shear strength model.
