ABSTRACT

This study deals with the dynamic elasto-plastic analysis considering a member buckling and the fuse type connection composed of an aluminum hub and a steel bolt. The study proposes a fuse type connection by means of yield of the steel bolt due to a tension stress realize the ductile failure collapse mechanism of the wall type spatial structure. The seismic response characteristics of spatial structures such as roof and wall types depend on their form and support conditions. A ductile elongation of the steel bolt due to a tensile stress is expected by avoiding the brittle collapse. This means that the response control can be feasible by the damper connection such as the steel bolt elongation due to a tension stress.
