Structures of temporary seating using scaffoldings have some connections which enable to easily assemble, disassemble and reuse members. The connections have non-linear stiffness through slipping and loosening in exchange for the high workability. The nonlinearity makes seismic responses of the structures complex. The structures are generally designed assuming that they are braced frames without considering the nonlinearity. A seismic response analytical model for the structures is suggested by static loading tests and shaking table tests using unit basic structures. It is verified that the model simulates response results of shaking table tests of large-scaled structures.
