本研究係先進行FRP構件續接之剪力試驗,試驗方式係分別以螺栓、結構膠各別進行物理、化學搭接試體之製作,以螺栓配搭結構膠進行混合搭接試體之製作。由力量加載過程觀察各型式搭接試體的受力行為,並於試驗結果探討各型式續接試體之極限載重與破壞模式。由試驗結果發現適當的螺栓配置可藉由螺栓剪斷的先後順序提供預警效果。再將此預警效果應用於FRP續接梁試體之製作,其續接方式係將一金屬續接器鎖固於欲進行續接的兩FRP梁中點,以不同續接器的鎖固型式,進行不同續接梁試體的規劃。以三點抗彎加載方式,進行各續接梁試體之試驗。由力量加載過程觀察續接梁的受力行為,並於試驗結果探討各型式續接梁之破壞模式,再將各型的式續接梁與未進行續接之原型梁進行勁度、極限載重及破壞模試之比較,最後提出FRP梁續接型式之建議,供後續相關研究上使用。再藉由化學續試驗之結果規劃一座以結構膠接合的全FRP人行棧道計算及評估,期望藉由此全FRP人行棧道示範案例讓國人對FRP材料的特性有進一步的認識。
This study will direct to the overlap and the connection shear test of FRP component.There are two methods to overcome the connection shortcoming of pultruded GFRP component and large span of temporary bridge.The first method is to conduct the bolt, adhesive and blend connection of GFRP component connection. The second method is to configure different bolt quantity and overlapping steel. Proceed a series of shear tests and conduct the force-displacement relationship, stiffness, ultimate strength and failure mode of FRP component from the 3-point bonding test. Study the shortcoming of physical connection and chemistry connection, then better conduct the overlapping configure with all overlapping steel for extra friction. Finally compare the result to each type of overlap and connect beam of stiffness, ultimate load and failure mode. Apply the result to the case of FRP pedestrian bridge.
