The dynamic assessment method of bridge's bearing capacity is always the researchhotspot in the academic field.In the past,The dynamic assessment research was focused onbuilding the connection between single beam's stiffness and frequency by regressing theexperiment data obtained in lab.By far,there is no well-rounded theory that can be used inpractice because of the test data's discretization.Though the span of plate bridge is usuallysmall,the task of static test is complicated,it is economical and ...
