在傳統的RC結構物之中,由混凝土發揮其抗壓強度,而張力部份主要是由鋼筋來承受,而鋼筋的鏽蝕問題,會降低其承載能力及結構壽命;而竹節鋼筋與混凝土之間必須要有足夠的握裹,才能發揮其拉力。因此本研究中嘗試以耐腐蝕性極佳的玻璃纖維棒(FRP rebar)來替代RC構造中的張力鋼筋,並研究不同的節高、節距、及纏繞角度對於FRP rebar與混凝土間握裹力之影響。
研究中首先製作FRP rebar,採用現成已經拉擠成型(pultruded)的玻纖棒,以纏繞機(filament winding machine)纏繞纖維紗束於外表,製成不同節高、節距及不同角度的纖維棒,並進行拉伸試驗以決定其基本材料常數。製作完成之纖維棒將於澆置混凝土時埋入混凝土中,待混凝土養護完成後進行握裹強度之測試,試驗時將量測纖維棒受力端及自由端的軸向位移,以建立bond-slip關係,並記錄其破壞模式。研究中將探討不同的纏繞方式所產生的節高、節距、及纏繞角度對於纖維棒與混凝土之間握裹力的影響。研究結果顯示,有縱向纏繞再加斜向纏繞的整體握裹強度優於橫向纏繞的組別,程序上也較為簡便。
Concrete must be reinforced with materials strong in tension because of its small tensile capacity. Conventionally, concrete has been reinforced with steel reinforcing bars. To transfer the forces from the concrete to the steel reinforcement, a good shear bond must be developed between the concrete and the steel. Steel reinforcing bars are manufactured with deformed surface to enhance shear transfer. In addition, it needs enough embedment length to develop the full capacity of the rebar. However, if the RC structures are exposed to deteriorative environments, it could leads to corrosion of the reinforcing steel. The whole structure might lose its loading capacity and reduce its service life. This urges the researches of finding a substitute for steel rebar or invention of new corrosion prevention technology. The FRP (fiber reinforced plastic) rebar with good corrosion resistance and high stiffness weight ratio will be a good candidate for this purpose. In this study, a filament winding technique is applied to commercially available FRP rods (with smooth surface) to produce different winding pitch, lug height, and winding angle. This simulated lug will provide the shear transfer mechanism between the FRP rod and concrete. These FRP rods are embedded in the concrete block during the concrete casting. A pullout test of FRP rod from the concrete cylinder was performed to examine the shear transfer capacity made from different winding pitch, lug height, and winding angle. The bond-slip data were recorded during the experiment. The optimum winding method to produce qualified bond, and the required development length for FRP rod are addressed.
Results show that the bond stress of FRP rod with longitudinal and oblique angle winding is better than the bond stress of a FRP rod with 90 degree winding. The process of the former is simple and easy to use than the latter.
