Abstract: A practical super high-rise reinforced concrete frame-tube structure was modeled by numerical analysis software (SAUSAGE) which was newly-developed by BRSC. Then seismic responses of the structure under major earthquakes were analyzed by nonlinear time-history analysis method based on the numerical structural models. The structural responses of storey drift, storey shear-force and structural damage distribution and development were obtained due to the excellent calculation ability and post-processing function of SAUSAGE software. The analysis results show that the structure has good seismic performance and can meet the requirements of no collapse under major earthquakes.

Keywords: SAUSAGE software; nonlinear time-history analysis; major earthquake; frame-tube structure
