Abstract:
This paper calculated the maximum elastic displacment respose based on the elastic acceleration spectrum in the current Seismic Design Code, and find the vary relations of the ratio of the elastic-plastic displacement to elastic displacement with the nature peorid of the SDOM systmes. The simplified formulas to calculate the elastic-plastic displacement are given based on the elastic acceleration specturem in the current Seismic Design Code by regression method.
