Abstract: The response spectrum analysis of the HL-3 carbon-based first wall under seismic condition is performed. The model containing the basic components of the host system is established, and the dynamics characteristics of the first wall system are achieved through the modal analysis. The response spectrum method is adopted for the seismic analysis of the first wall model, and the formation and stress distribution of the first wall structure under the seismic condition is obtained. The analysis results show that the carbon-based first wall meets the safety requirements of structural design.
