Abstract
Hangzhou alipay building is mainly a multi-storey building, the main structure of this building is the steel framework-RC seismic wall system. The structure of this building is completely divided into three independent zones with seismic joints, denoted as zone-A&B&C. The joints studied in this paper locate in the steel cantilever truss of zone-A building. Reduced-scale experiment on the steel cantilever truss joints was carried out to verify its reliability and bearing capacity. The stress and deformation of specimens were investigated during monotonous loading process. It was indicated that the truss joints showed local buckling and yield at the loading class higher than design load. The finite element model was built and was in good agreement with experiment result. Both the experiment and numerical results demonstrated that the truss joints had sufficient strength reservation and its performance will be qualified with the practical engineering after optimization design.
