Abstract
An unseating prevention cable is designed as the fail-safe system; therefore, it is required to be tested under various situations in order to confirm the safety of the system during and after earthquake. In this report, steel girders with unseating prevention cables were loaded in tension either parallel to or skewed with the girder and the behavior of bracket plates and webs were investigated. Test results indicated that stresses in the bracket plates were under the yield stress for both cases; showing the adequate strength for the bracket under the design load. However, in the cases for skewed loading, the web and the end stiffener were deformed due to contact with the cable, indicating the decrease in the shear strength.
