DEVELOPMENT OF A DESIGN PROCEDURE FOR CONCRETE TRAFFIC BARRIER ATTACHMENTS TO BRIDGE DECKS UTILIZING EPOXY CONCRETE ANCHORS by

A guide for the design of epoxy anchors for the use in concrete traffic barriers was developed in this study. A series of dynamic bogie tests and static tests was conducted on single and double anchors. The dynamic increase factor for the noted anchors was determined to be 1.06. Protective epoxy coatings for the anchors was observed to contribute to a 9 percent decrease in anchorage strength. The effects of anchors located in close proximity to each other was also investigated. Calibration factors were developed to apply recommended changes to the ACI code for use in bridge rail anchorages. A load model was developed to estimate the lateral impact loads for non
