Research on Deformation Reliability Model of Beam Bridge Based on Poisson Crossing Rate Analytical Method
As one of the important structural responses collected by the bridge health monitoring system(HMS),deflection can reflect the stiffness of the structure to a large extent,especially for beam bridges,and is an important indicator for evaluating the health of the struc-ture.In order to make full use of the massive deflection monitoring data,this paper establishes an explicit model of the deformation reliability of the beam bridge based on the Poisson crossing rate theory of the non-stationary process,evaluates the reliability of the bridge deforma-tion,and conducts Monte Carlo simulation verification.The results show that the calculated values of this method are in good agreement with the Monte Carlo simulation results,and can make full use of the deflection monitoring data to more accurately assess the reliability of the beam bridge's deformation.
