Abstract EN
This study deals with partial cylindrical truss walls equipped with damper connections due to horizontal earthquake motions.
The damper connection consists of an aluminum ball joint, an aluminum hub, and a steel bolt.
A ductile elongation of the steel bolt due to a tensile stress is expected by avoiding the brittle collapse.
The study proposes a fuse-type connection by means of yield of the steel bolt due to tension stress realized by the ductile failure collapse mechanism of the wall-type spatial structure.
The proposed truss wall with the fuse-type connection can realize a deformation of nodes within the restriction for avoiding a nonstructural member damage.
It is confirmed in the dynamic elastoplastic analysis that the control of the dynamic collapse mechanism such as the steel bolt elongation can avoid a brittle collapse mechanism such as a chain of member buckling.
The evaluation method is also proposed by means of the limit displacement considering a ductility factor of the steel bolt within 2.0.
