鑒於近年來例如921集集地震、2016年美濃地震所造成的震害發現,台灣住商混合類型建築物易因軟弱層效應而發生嚴重破壞甚至倒塌,加上台灣地區活動斷層甚多,其中以具高速度脈衝、地表大位移等特性的近斷層地震更具威脅性。故專家學者們致力於近斷層建築物抗倒塌之分析模擬與耐震補強技術,透過振動台大型實驗對試體最終破壞進行結構性檢討,搭配電腦軟體建立數值模型,期望能提供評估與補強技術給國內工程師參考。
本論文根據國家地震工程研究中心(NCREE)所進行的一系列構件反覆載重實驗及三軸向振動台試驗,並強調台灣既有非韌性配筋建物之特性,使用有限元素軟體Abaqus分別採取靜力與動力分析,其中針對如何建立適當的網格元素與模型以有效模擬其勁度、強度、破壞模式及非線性行為等詳加研討,希望可改善目前國內耐震設計規範之缺失,並促進既有RC建物補強工法的研發,最後統整模擬獲得的動態行為與相關資料,探討建築物及相關構件行為之分析技術與實務需求,供後續地震工程科技對於鋼筋混凝土結構物受震反應之研究使用。
In view of recent earthquakes including the 1999 Chi-Chi earthquake and the 2016 Meinung earthquake, it shows that the old existing RC frame structures in Taiwan are susceptible to severe damage or even collapsed due to the weak layer effect. Also, the effects of a near-fault ground moions ofen contain a long period velocity pulse and permanent ground displacement. Therefore, experts and scholars are committed to the analysis of the non-ductile RC buildings subjectd to near-fault ground motions. With the large-scale specimens of the shaking table experiments and the numerical model established by computer software, it is expected to provide a wealth of information to engineers.
This paper is based on a series of component cylic loading tests and triaxial shaking table tests at the National Center for Research on Earthquake Engineering (NCREE), and evaluates seismic performance of deficiencies of non-ductile reinforced concrete structures in Taiwan. The finite element model will be done using the software ABAQUS, and focus on how to mesh appropriate elements to simulate the stiffness, strength, failure and nonlinear behavior of the model. It is hoped to improve the lack of current seismic design codes and promote the developing of existing RC building methods. Finally, all the relevant data of my paper, including the material properties and the dynamic behaviors obtained by the simulation, are provided for the research on seismic behavior of reinforced concrete structures in the future.
