本研究利用壓電陶瓷材料製作壓電感測器與致動器。利用其具正壓電效應之特性做為感測器,進行RC牆、柱構件於地震力激發下對試體之受力反應監測。再以壓電材料具正逆壓電效應之特性做為感測器與致動器,進行RC牆構件受地震力作用後之損傷評估。
動態牆、柱試驗是以一組動態千斤頂做為施力機制,以位移控制之方式對試體上部混凝土區塊施加不同等級之地震歷時,其中RC牆試體分為有界面滑移與無界面滑移等兩類,而RC柱試體分為撓曲破壞、撓剪破壞與剪力破壞等三類。試驗皆使用後埋式壓電感測器,探討壓電訊號與試體受力、位移之關係,並與建立之理論遲滯迴圈與試體實際反應做比對,以等效黏滯阻尼比的概念計算其能量,以此定義RC牆、柱構件之震損程度,試圖以壓電訊號計算之等效黏滯阻尼比判斷結構之損傷程度。於RC牆試體另外使用壓電材料製成壓電致動器,在地震力作用後激發訊號,量測壓電感測器之壓電訊號,計算其累積損傷指標,並比較不同等級地震力作用下之損傷指標。


In this study, using the piezoceramic as sensors to detected the displacement and force of the seismic in reinforced concrete (RC) walls and columns. Furthermore, using the piezoceramic as sensors and actuators to perform structural health monitoring in RC walls.
The dynamic wall test and dynamic column test are applied different levels of seismic deformation by a set of dynamic actuator. We use two difference kinds of RC walls: slipping and without slipping. Three difference failure modes of RC columns: flexure failure, flexure and shear failure and shear failure. The post-embedded piezoceramic sensors are used to perform the displacement and force which is applied on the specimens. Using piezoceramic sensors to investigate the relationship between the signal measured by the sensors and the force and deformation of the specimens. Calculating the energy dissipation by the equivalent viscous damping ratio and define the damage level of RC structure.
In addition, the post-embedded piezoceramic sensors are used to perform structural health monitoring in RC walls. Using the piezoceramic as sensors and actuators in the specimens. Calculating and comparing the damage index after acting different scales of seismic duration.
