The present paper is a result of a collaboration in IASS WG 8 for metal spatial structures to prepare state-ofthe-art reviews for earthquake response analysis methods and equivalent static seismic loads for metal spatial structures. It quotes mainly investigations from IASS symposia and related journals. First, the dynamic response characteristics of metal spatial structures are briefly explained. This is followed by a review of analytical methods for evaluating earthquake responses. Finally the equivalent seismic loads proposed for metal spatial structures are reviewed and some comments for future analysis of failure and fragility are provided.
