【摘要】 以地震反应谱的形式,阐述了复阻尼系统在频域求解过程中容易出现的问题。通过理论与计算分析得知,这些问题对反应谱计算有很大的影响。另外,还初步分析了时域精确法及频域分析方法的计算效率,认为时域精确法比频域分析方法的计算效率高。更多还原

【Abstract】 Based on theoretical analysis and calculation of seismic response spectra in frequency domain,some problems occured in the analysis are pointed out. The problems have significant influence on results of response spectra. Moreover, the calculation efficiency of exact analysis methods in time and frequency domain for a single degree of freedom system with complex damping are compared and the conclusion is that the exact analysis method in time domam is better than the later.更多还原
