In recent years, in some cases, the seismic resistance of temporary structures can not be ignored due to prolonged construction period or the like. However, the seismic behavior has not been clarified, and appropriate design methods have not been established at the present time. In this study, we focused on the braced excavation work which is frequently used in the temporary structure, and based on the estimation result of the seismic behavior by the nonlinear dynamic analysis, the application of the simplified evaluation method by the beam spring model We are examining the possibilities. In nonlinear dynamic analysis, an analysis model is created with reference to the displacement measurement result of the earth retaining wall described in the past literature, and after confirming the consistency between the excavation analysis and the measured value, Analysis is being carried out. As a result, We confirmed that there is a possibility that a dynamic analysis can be reproduced by the static analysis using the seismic deformation method.
