2016年美濃地震在台南造成嚴重損失，特別是對中高樓層住商混合使用建築。根據地震災害調查結果顯示，結構損壞的主要原因如下：（1）軟弱之底層；（2）非韌性配筋細節。為了掌握中高樓建築物的耐震性能，本研究設計了一系列具有1990年代台灣典型住商混合建築結構特徵的1/2縮尺三層樓鋼筋混凝土（RC）立體構架試體，並在振動台上測試了受遠域地震及近斷層地震之影響。本文將介紹試體的設計及近斷層地震動的振動台測試結果。此外，測試結果也與非線性動力方法之分析結果進行比較，其可作為中高樓層鋼筋混凝土建築耐震性能評估提供重要參考。

The 2016 Meinong earthquake caused serious damages in Tainan, especially to several mid to high-rise mixed-use residential and commercial buildings. Earthquake reconnaissance investigations show the major causes of damaged structure as follows: (1) soften and weakly first story and (2) non-ductile detailing of structure member. In order to grasp the seismic performance of the mid to high-rise buildings, a series of specimens were designed with the structural characteristics of the typical mixed-use residential and commercial buildings in Taiwan in the 1990s. A 1/2 scale three-story reinforced concrete (RC) frame infilled with RC walls has been subjected to near fault and far field earthquakes on the novel shaking table. The scaled specimen will be extended to seven-story by applying the concept of modular design, which is going to be tested in the series study. The dynamic behavior and damage features of the building under near-fault ground motions will be studied. In this paper, the design of the specimen, instrumentation layout, and the findings from the shaking table test from the near-fault ground motion will be introduced and discussed. Moreover, the test results were compared with the analysis results using the nonlinear dynamic analysis method. The comparison provides an important reference for researches on developing the seismic performance assessment tools for mid to high-rise RC buildings.
