| 摘 要： | 在《建筑抗震设计规范》(GB50011-2001)中,反应谱在长周期区段出现了大阻尼比曲线值大于小阻尼比曲线值的反超现象。分析认为,《规范》的多阻尼比反应谱在3.39～6s的长周期区段可能不适用,而用虚拟等值点法修正后所得参数简单且易于使用。反超现象是因计算误差引起,还是因特定的物理背景造成,值得深究。

| Abstract: | In the Code for Seismic Design of Buildings (GB50011-2001),the spectral value for large damping-ratio is higher than that of small damping-ratio in the long-period portion. The code's multi-damping-ratio-spectra maybe are not suitable in the long-period part of 3.39-6s. Parameters are simple and easy to be used after correction by using the method. Whether the abnormal phenomenon is caused by calculating error or special physical setting is worth to be studied. |
