Harmony Response Analysis of a Simple Supported Beam Steel Bridge Based on ANSYS

Abstract:

The purpose and meaning of bridge health monitoring is sketched in this paper. In order to study of the structure of the bridge health monitoring problems, First of all, a finite element model for simply supported steel beam is set up on the basis of the Finite Element Theory and the software ANSYS in response to laboratory of the finite Element Theory and the software ANSYS in response to laboratory experient. Identify the different injury by comparing the index value and the rate of change. Through adding instantaneous excitation to the mid-span, do Harmony Response analysis for different injury of steel bridge model to reveal the frequency amplitude diagrams, from these diagrams can be found on the "peak" response. We can identify the different injury by comparing the index value and the rate of change.
