Dynamic responses of cyclindrical lattice shell roofs under horizontal earthquake motions with arbitrary direction by shaking table test

Abstract

This paper is intended as an investigation of the seismic response behavior of cylindrical lattice shell structures by shaking table tests. The seismic vibration tests are carried out using small scale models with shell span of 60 cm of cylindrical lattice shell roofs with substructure under horizontal motions in arbitrary direction. From the experimental results, the effects of difference of earthquake input direction and relationship between mechanical properties of roofs and substructures on response behavior of shell roofs are made clear. In addition, it is confirmed that the seismic response evaluation methods proposed in previous papers (Takeuchi et al. [1] ~ Takeuchi et al. [3]) apply to the responses subjected to earthquake motions with arbitrary direction.
