由於台灣位於地震帶上,建築物的耐震能力顯得相當重要,而剪力牆是一種經濟且有效的耐震構件,尤其對於一些老舊校舍及中低樓房,可以利用剪力牆來進行補强的工作,提升原有建築物的強度,接著根據內政部營建署重新規劃地震震區後與修正建築耐震設計,一般建築物的耐震標準提高,故剪力牆的耐震行為及能力值得探討。
國內外學者對於含場鑄剪力牆之構架已有不少的研究,但對於含預鑄剪力牆之構架的研究卻不多,其次,由於近年來預鑄技術的進步,不但品質有一定水準,同時成效性較好,故預鑄工法開始迅速發展,有鑑於此,本文將研究預鑄剪力牆在反覆載重作用下的破壞模式,極限強度的計算,位移與載重的關係,以及韌性比與遲滯圈中的能量消散量,同時透過不同的參數設計,觀察其影響程度,作為未來設計參考之用。
過去對於剪力牆的實驗往往未施加軸力,或者是利用千斤頂來加載軸力,容易造成應力集中的現象,而本文則採用雙邊槓桿的施加方式,有效將軸力均佈在試體上,且具有軸力變化小及總軸力不變的性質,與實際結構體的行為較為符合,進而更為準確預測結構體的行為反應。
Duing to Taiwan is located at seismic regions,so a building anti-seismic ability is conspicuously importment . Shear walls are economicsal and effective anti-seismic elements and widely recognized for providing adequate lateral load resistance and drift control for building . It is a superior rehabilition methods for damaged building. It can improve strength and mitigate collapsed risk .
It has been shown in the literature that,cast-in-plane shear walls are generally used but precast shear wall are very limited . However,in recent years,the precast shear wall has supported the development of these walls because of their economy,simplicity of construction,and desirable lateral load behavior. For these reasons,this paper describes destruct behavior of precast shear wall,calculation of ultimate strength,relation of displacement corresponding to load,ductility,and energy dissipation .
