摘要

維冠金龍大樓在2016年0206美濃地震倒塌，兩年後雲門翠堤大樓在0206花蓮地震崩塌傾斜，根據這兩棟之現場損壞，依照損壞狀況，研判可能之破壞原因及倒塌模式，並作探討分為，（1）根據鄰近地震觀測站資料了解地震的基本性質、（2）了解二大樓在平面與使用變更前後之偏心與扭矩變化，（3）此兩棟大樓可能之倒塌機制。本文依據地震歷時分析，研判倒塌機制，再以現場照片佐以說明，結構系統不佳、軟弱層及偏心扭矩是造成倒塌或崩塌傾斜的重要原因之一。

The Weiguan-Jinlong Building collapsed in the 0206 Meinong earthquake in 2016. After two years, the 0206 Hualien earthquake caused the inclination of Yunmen-Cueidi Building. To understand why the Weiguan-Jinlong Building and the Yunmen-Cueidi Building collapsed, the mechanism which led to their destruction will be discussed in this paper in light of the damaged condition of the two buildings. The discussion is divided into three parts, the first part is the study of the earthquake's properties based on the measurement data from the seismic station nearby. The second part is the comparison of the torsional eccentricity caused by the seismic forces between the former and later arrangement of the walls. The final part is the preliminary assessment of the damage mechanism of the two buildings. Based on the result of the sequential analysis of the simulation model and the supporting evidence provided by the site investigation photoes, we conclude the main reason underlying the damage mechanisms of the Weiguan-Jinlong Building and the Yunmen-Cueidi Building are highly correlated with the defects observable in the structural system, the weak levels within the building, and the torsional eccentricity caused by the earthquake force.
