論文中文摘要:本論文利用常用玻璃纖維強化高分子(Glass Fiber Reinforced Plastic, GFRP)複合材料,以不同組合斷面的型式改善單一構件勁度不足之問題,因應設計之需求選擇適當縮尺斷面,作為實尺寸組合式GFRP梁-版系統之參考。本論文針對不同構件斷面選擇GFRP組合型式梁構件,並配置GFRP平版製作梁-版系統,以縮尺型式組合梁構件及梁-版系統進行三點抗彎試驗。藉由各梁構件及系統之試驗結果,所得之載重、勁度及破壞模式等,與單一構件相互比較,可由實驗得知組合式梁構件可有效提升之強度及勁度,則梁-版系統型式藉由版構件的擺放,使梁構件均勻受力,探討各種梁構件及系統結構受力行為。期望依不同組合梁構件型式及梁-版系統方式,找出提升整體系統勁度及強度的方法。最後將組合型式梁構件及整體結構梁-版系統,以ANSYS有限元素分析,將分析與實驗結果進行比較,進而藉此驗證正確性。透過縮尺實驗與分析之方式進行破壞模式之探討,以達到確保各構件接合後整體結構之安全,並提出經濟效益佳之組合型式FRP梁-版系統。
論文英文摘要:This study focused to Glass Fiber Reinforced Polymers (GFRP) composite material members with different types of section combination in order to improve the stiffness of a single component. In response to design requirements, the appropriate GFRP section was selected with reference to the actual scale of the GRFP beam-deck system. This paper uses different beam sections which are bonded together with a GFRP plate to conduct a three-point bending test. According to test results, the ultimate strength, stiffness and failure mode of the combined component is enhanced when compared to the single component. Finally, the Finite Element Method (FEM) numerical simulation of the combined GFRP beam-deck system was done with ANSYS before comparing the experimental result with the analytical result and thus, verifying the accuracy of the FEM model. Through scaled experiments and analysis conducted to investigate the failure mode, the combined GFRP beam-deck system had achieved the optimum safety requirements of its connected members and proves to have a good economic.
