The effect of initial static load on the instantaneous response is related to the stiffness, mass and damp
在對底層邊柱突然失效的高層結構進行分析時，必須計算結構的瞬時動力響應。 -
Then, the hilbert transform is applied to each modal response to obtain the instantaneous amplitude and phase angle time histories. a linear least - square fit procedure is proposed to identify the natural frequency, damping ratios, physical mass, damping and stiffness matrices from instantaneous amplitude and phase angle for each modal response
然後對各階模態響應進行hilbert變換，得到瞬態幅值和相位角的時間歷程，再運用線性最小均方擬合來識別自然頻率、阻尼比、質量、剛度和阻尼矩陣。
