DEVELOPMENT OF DURABLE ANCHORAGE SYSTEMS FOR BRIDGE EXPANSION JOINTS. FINAL REPORT
Many anchorage systems of bridge expansion joints in the medium movement range have failed within a relatively short period of time after their installation. The embedded anchor devices have become loose under traffic impact and have caused deterioration of the adjacent concrete deck. After the performance of various domestic and foreign designs were assessed, factors affecting the anchorage system performance and failure were identified. Accordingly, improvements in the anchorage system components, which are built in conjunction with the anchor devices, were recommended to reduce the intensity of traffic impact loads transmitted to the anchor devices. Subsequently, an analytical procedure was developed to quantify the intensity of the dynamic traffic loads transmitted to anchor devices and to design anchor devices to resist those loads.
