Cyclic loading test of steel octagonal section pier models

摘要

Highway structures in an urban area need to function effectively immediately after an earthquake occurs in order to allow relief operations in the damaged zones. The seismic design philosophy adopted here is that safety coefficients should be based on a minimum total cost of loss occurring in the social system. Simple and quick repair of partially damaged structure is therefore an important consideration in functional design. In the tests reported below, octagonal section steel bridge pier models that had previously been subjected to seismic loading were simply repaired and then retested under cyclic loading. Test results showed good recovery in the load-deflection hysteresis curves.
