Abstract
The ambient test and the skillof system identification are very popular in recent years,like the ambient test of buildings,by using the skill of system identification can get the period of buildings.
It is quite common that the period of a building can be identified easily and accurately from ambient test recorded in that building. However, this is not true for damping ratios. It is found that identified damping ratios vary to some extend depending on the identification methods, the strong motion records, and the floor levels where the strong motion was recorded. This study is going to investigate how these happen and is hoping to suggest proper values of damping ratio for the design of steel and RC buildings in Taiwan.
