摘要


磚牆結構在台灣被廣泛的使用,不論是古蹟、校舍、在鄉村較為 低矮之樓房或是在建築中作為隔間牆使用,而磚牆結構本身耐震能力 較低,且台灣位於環太平洋地震帶上,地震的發生相當頻繁,磚牆的 耐震補強因此相對重要,針對磚牆受到水平於牆面之地震力時,所受 到之剪力破壞,以及受到垂直於牆面之地震力時,所受到之彎矩 破 壞,進行材料補強的相關試驗,是有其必要性。 本研究為探討如何有效提升磚牆之耐震能力,使用纖維補強方式 進行試驗,分別選用玄武岩纖維、碳纖維、玻璃纖維三種纖維進行試 驗及比較,本研究也考慮比較添加環氧樹酯作為纖維與磚牆之黏著劑 與否。為更準確的模擬地震力對磚牆所造成的破壞,磚牆受到地震力 影響時,產生剪力作用與彎 矩作用, 利用剪力試驗 以及彎矩試驗模 擬,試驗之試體皆於接縫處使用水泥砂漿接合,試體完成後在其表面 黏貼纖維,而後使用萬能試驗儀進行施壓直至試體產生剪力/彎矩而 破壞。 試驗結果顯示,(1) 運用纖維補強磚牆確實能使磚牆之耐震能力 有所提升(2) 有添加環氧樹酯膠水之試體更能有效的黏著纖維與磚 牆,使磚牆運用纖維補強之效果更為顯著。(3)玄武岩纖維與碳纖維 之補強效果比玻璃纖維更為有效。

The masonary structure is widely used in Taiwan, whether it is a monument, a school building, a low-rise building in a village or a partition wall in a building, and the brick wall structure itself is low in earthquake resistance, and the earthquake in Taiwan is located in the Pacific Rim. In the belt, the occurrence of earthquakes is quite frequent, and the seismic strengthening of the brick wall is therefore relatively important. When the brick wall is subjected to the seismic force horizontally to the wall surface, the shear force is damaged, and when the seismic force perpendicular to the wall surface is received, It is necessary to carry out relevant tests for material reinforcement due to the damage of the bend. In order to effectively improve the seismic capacity of brick walls, this study used fiber reinforcement to test and compare the three fibers of basalt fiber, carbon fiber and glass fiber. The study also considered adding oxyredoxide as fiber and brick. Adhesive on the wall or not. In order to more accurately simulate the damage caused by the seismic force on the brick wall, when the brick wall is affected by the seismic force, the shearing force and the bending effect are generated. The shear test and the bending test are used to simulate the test. The cement mortar is used for bonding, and the fiber is adhered to the surface after the test piece is completed, and then the pressure is applied by the universal tester until the test piece is sheared/curved. The test results show that (1) the use of fiber-reinforced brick walls can indeed improve the seismic resistance of brick walls. (2) The test body with added oxygenated resin glue can effectively adhere the fibers and brick walls, so that the brick wall can be used. The effect of fiber reinforcement is more pronounced. (3) The reinforcing effect of basalt fiber and carbon fiber is more effective than glass fiber.
