Title

FINITE ELEMENT MODELING OF THE DYNAMIC RESPONSE OF A COMPOSITE REINFORCED CONCRETE BRIDGE FOR STRUCTURAL HEALTH MONITORING

Pages

  1-14

Abstract

 This paper describes three-dimensional (3D) finite element (FE) modeling of a composite steel stinger supported reinforced concrete (RC) deck highway BRIDGE subjected to moving truck loads. FE models were validated using test data that were generated elsewhere for STRUCTURAL HEALTH MONITORING. The FE models were established using a commercial FE analysis package called ABAQUS/standard. The case study BRIDGE was discretized to a combination of shell and solid elements which represent the deck and piers, respectively. Numerous constrain interactions were defined to make the model suitable to obtain accurate results. MOVING LOADS induced by two standard AASHTO trucks were developed through a specific load-time history, applied on 35 nodes on the superstructure. To study the DYNAMIC BEHAVIOR of the BRIDGE under a moving load, a modal analysis followed by an implicit dynamic analysis was carried out. Acceptable agreement was found between the field measurements and FE simulation. Most concerned dynamic response was strains at different locations in BRIDGE girders and columns, because it is the only critical parameter that can be measured with confidence during SHM at site. The range of strains determined in analysis was reasonably close to the measured strains at the site of the study BRIDGE. Several parameters including DAMPING, TRUCK WEIGHT and speed, and MATERIAL PROPERTIES were studied. TRUCK SPEED had the highest effect on strain response of both girders and columns.
