近幾年來，IC高科技產業及精密製造工業技術進步迅速。這些產業對生產環境相當的敏感，因此對地板振動的要求也更加嚴格。樓版振動可以是週遭環境的微振動、交通或施工造成的。所以如何減低及預測一新工廠樓版的振動範圍將是未來研究的新領域。
本研究針對9棟建築物進行微振動量測實驗，進而比較了解從室外自由場傳遞至建築物內的振動衰減量。另外，從2棟基底隔震設計建築物的實驗中，探討鉛心橡膠隔震墊對微振動的影響。最後，本研究也針對不同厚度的樓版試體進行衝擊槌實驗，分析不同樓版厚度與其阻尼比之間的關係。
經由對9棟建築物進行微振動量測實驗及樓版衝擊載重實驗，歸納以下幾點結論：

1.建築物地下室有無土壤包圍，對低頻（8Hz以下）的微振動衰減量影響最大。
2.以1/3八度音頻寬理論分析微振動衰減量，得知建築物有基底隔震設計時，當微振動傳至最底層樓版（無隔震），有衰減的現象；但再傳至隔震層樓版，振動量卻增加了2～3倍。因此，基底有隔震設計的建築物對微振動衰減的助益並不大。
3.在樓版衝擊載重實驗中，發現樓版厚度的增加，其阻尼比也隨之增加（樓版厚度加倍，則其阻尼比增加1.5～2倍）。
4.在樓版衝擊載重實驗中，若將一腳架往內移，則樓版B與樓版C的自振頻率增加了1.47倍及1.28倍，而阻尼比也隨之增加了1.82倍及2.17倍；若在樓版上挖4個圓孔後，樓版B與樓版C的自振頻率降低了0.98倍及0.97倍，而阻尼比也降低了0.89倍及0.84倍。

IC technology advancement and precision manufacturing industries bloomed in the past decades. Owing to their demands for sensitive production environment, strict requirement for floor vibration are ever growing. Floor vibration sources may come from ambient vibration, traffic induced vibration, or construction work. How to reduce or predict the floor vibration level in a new plant becomes a new frontier for research.
This research measured ambient vibration condition of nine buildings. Comparisons were made to understand the vibration reduction characteristics from ground soil into the building. Two base-isolated buildings were also studied to compare the effect of LRB dampers. Different thickness test floor specimens were manufactured and tested. The purpose was to identify the relationship between the floor thickness and inherent damping ratio.
By measuring the nine buildings’ ambient vibration and testing different thickness floors with impact loading test, the following conclusions are drawn:

1.The basement covers with or without soil has the most influence on abatement of ambient vibration in low frequency (under 8Hz).
2.To analyze the abatement of ambient vibration by one-third octave bands theory, a conclusion can be drawn that the buildings with base isolator do not help to decrease ambient vibration.
3.In the test of floor impact loading, we discovered that increasing the thickness of floor will as well increase damping ratio (when the thickness of the floor doubles, the damping ratio also increases by 1.5~2 times).
4.In the test of floor impact loading, if we move a stand kick inward, the natural frequency of Floor B and Floor C have increased by 1.47 times and 1.28 times; moreover, so does the damping ratio has increased by 1.82 times and 2.17 times. Otherwise, after we opened four holes in each floor then finding out that not only the natural frequency of Floor B and Floor C have decreased by 0.98 times and 0.97 times but also the damping ratio has decreased by 0.89 times and 0.84 times.
