Finally, a practical seismic analysis method is presented. Through a reasonable assumed distribution of lateral forces, the capacity curve can be derived from the story shear-displacement curves. And by using equations suggested by ATC-40, the corresponding capacity spectrum, period, damping ratio and PGA can also be obtained. This method can provide not only collapse PGA of a low-rise RC building structure, but also damage conditions of members at a specific PGA. Combining with the deterioration rule for RC column after multiple earthquakes, it can also be applied to seismic analysis for after-earthquake or aged buildings.

最后则提出一套适用於中低层RC建筑结构之实用耐震诊断法，依照合理假设之地震力竖向分配型态及ATC-40建议公式，可再将层剪力-层间变位曲线换算为基底剪力-屋顶位移能力曲线，并计算对应之等效周期、阻尼比与PGA，除可评估结构整体之崩塌地表加速度外，也可由特定PGA反推对应的构件破坏程度，亦可配合震后折损修正，应用於结构之震后与经年耐震评估。

Then based on CWMS, we propose a new method to enhance the resolution of seismic traces. Firstly, we divide the seismic signal into proper segments by Gabor molecule-windows adaptive to the signal, where each segment is regarded stationary, and then transform it into the Gabor domain. Secondly, we deal with the amplitude spectrum for each segment to expand the frequency band of the spectrum in the Gabor domain. Finally, taking inverse Gabor transform on modified time-frequency coefficients, we get the high-resolution signal.

然后基于变子波模型，提出了一种新的提高地震记录分辨率的方法：第一步，用自适应于地震记录的Gabor分子窗把地震记录恰当地划分成若干片断，每段内信号近似平稳，然后将地震记录变换到时间-频率域；第二步，在变换域对每个分子窗内信号的振幅谱进行处理以拓宽频带；最后把处理后的时间-频率域函数反变换回时间域得到提高分辨率后的结果。
