Identification of Vehicle Parameters from Bridge Dynamic Response
No Thumbnail Available
Every bridge has certain restriction for the vehicle load and length. When the limit exceeds, permit has to be sought from the competent authority to allow the vehicle to cross the bridge. Weigh bridges are installed at important sections of highways to restrict the overloaded vehicles to enter the bridge. In the present study, a conditional probability based approach known as "particle filtering technique" has been utilized to estimate the physical parameters of a passing vehicle from the measured dynamic response of the bridge. The particle filter technique requires a mathematical model of the system for the repeated generation of response samples, which is termed as "Forward Scheme". In the present work semi analytical method has been developed and interfaced with the particle filter method for generation of response samples. Here, the bridge has been modeled as Euler Bernouli beam with uniform cross sectional properties. ...
