FATIGUE AND ULTIMATE STRENGTH OF TENSION RODS AND THEIR CONNECTIONS

Abstract

Although cables are the most popular structural material for tension structures, high-strength steel rods are also used as tensile members. However, because of the fact that these rods were origmally developed as pre-stress members and temporary members, performances against high-stress cyclic loads have not been cleared yet. Also for the typical pin-block connections, ultimate or fatigue strengrth including eccentric pin are yet to be clarified. In this paper, above characteristics are confirmed by tests and analyses, followed by discussion on the performance of the overall system.
