摘要

本論文係使用具有質量輕、耐候性佳及高強度比之玻璃纖維強化高分子(Glass Fiber Reinforced Plastic , GFRP)複合材料構件，進行格柵型式剪力牆側推實驗與分析。首先將GFRP構件組合成框架，另將GFRP格柵版放置於框架中形成格柵式剪力牆，並進行側推實驗並探討其成效。試驗規劃使用雙腹板I型斷面構件作為框架之梁-柱部分，其梁-柱接頭則利用GFRP版材裁切成所需形狀。梁-柱接合方式利用環氧樹脂與GFRP插銷之接合方式。框架型式分成空構架、加入薄型格柵剪力牆及加入厚型格柵剪力牆。兩種格柵式剪力牆再細分成加入兩種不同填充材料並進行側推實驗。實驗顯示，加入格柵剪力牆後其極限載重、初始勁度分別提升1.3倍及1.4倍。加入填充材後其極限載重、初始勁度最大可分別提升2.5倍及4.5倍。SAP2000數值模擬軟體之應用，以塑性鉸方式進行框架的設定；而格柵構件則係使用「等值柱概念」進行參數設定。分析結果與實驗值比較之誤差皆在10 %以內，顯示分析與實驗力-位移曲線相近，期望本論文之數值模型可供後續相關研究使用。

This thesis presents the push-over test of a frame system made from lightweight, high-strength and weather-resistant GFRP composite. FRP grating shear wall system is combined into the frame and the mechanical behavior and effectiveness of the grating shear wall is investigated in a push-over test. The columns and beams of the frame are made of double-web I-beams. The beam-column joints are made by inserting cut GFRP platess into the hollow of the beam and column, and then locking the joint with GFRP pins in addition to epoxy adhesive. Three types of frame systems were involved: un-grated frame; thin-grated frame; and a thick-grated frame. Each of the gratings were infilled with two different materials. Experimental results show that the maximum ultimate strength and initial stiffness increased by 1.3 folds and 1.4 folds, respectively, after placing the unfilled-grating system in the frame. After adding the infill material, both the ultimate strength and initial stiffness were enhanced by 2.5 folds and 4.5 folds respectively.
Using SAP2000, a plastic hinge was set for the frame. The grating members of this study use an “equivalent column” plastic hinge concept. Analysis results showed a good correlation with experimental results with an absolute error less than 10 %. The numerical models of this thesis could be used for future studies.
