The importance of seismic conceptual design and the prevention of quasi - resonance and torsional damages of high - rise building under strong earthquake are ernphasized.
The importance of seismic conceptual design and the prevention of quasi - resonance and torsional damages of high - rise building under strong earthquake are emphasized.
The continuous model is adopted in the torsional vibration frequency and resonance of shaft system, the lumped parameter equivalent applied in the sub-synchronous resonance.
