The purpose of this study is to present two models such as the hysteretic restoring force characteristic models of the system truss member for elasto-plastic dynamic analyses of aluminum alloy latticed wall structures and the single degree of freedom equivalent model for predicting the earthquake response. As far as the single degree of freedom equivalent model is concerned, the modeling procedure of the simplified single degree of freedom vibration system is significant in order to predict the earthquake elasto-plastic responses of the latticed wall using the earthquake response spectrum and the property of the energy conservation. The estimation results obtained by using the proposed vibration model are verified to be in close agreement with the elasto-plastic dynamic analysis results of the full numerical analysis model.
