Abstract

Seismic response of arch structures with supporting substructures is known to be amplified in vertical directions even under horizontal input, and their amplitude changes along the relationship between mechanical properties of roofs and substructures. Although a large number of studies on seismic response behavior by numerical analyses have been made, seismic response behavior by vibration test has not been sufficiently investigated. In this paper, seismic vibration tests are carried out using small scale arch roof models with supporting substructure in order to confirm influence by the relationship between mechanical properties of roofs and substructures. The validity of response evaluation method proposed in previous papers is examined.
