Static loading and repeated low cycle loading tests are carried on a new type of foot joint of concrete filled steel tubular. The load-displacement curve under static load,load-displacement hysteric curve under repeated low cycle load and strain data at key points are presented. The test results show that the new type of foot joint is featured with excellent working performance and high ability of absorbing energy.
Keywords: concrete filled steel tubular; foot joint; aseismatic; test; anchor bolts
