Abstract / 摘要	台灣典型低層街屋中常出現平行騎樓方向之側邊門型開口磚牆，此類磚牆雖有開口，仍可提供一定強度與剛度，亦會影響構架之破壞模式。早期磚牆多為加強磚造，近期磚牆則多為填入式，兩者行為及柱牆互制關係有所差異。因此本文以有無開口及磚牆構法為變因，進行足尺含磚牆RC構架試體之面內加載試驗，並將試驗結果與既有分析模型比對。試體共有四座，其中兩座含側邊門型開口，兩座無開口，皆分別以加強磚造及填入式構法製作。試驗結果顯示，磚牆裂縫發展及滑移情況受磚牆圍束條件影響，無開口試體磚牆均出現對角裂縫，有開口試體則在試驗初期即於柱牆介面附近開裂，磚牆整體向開口側滑移。兩座加強磚造試體初始開裂即達極限強度，磚牆破壞模式歸納為對角拉力破壞，而填入式試體磚牆於裂縫產生後才達極限強度，兩座試體均為灰縫滑移破壞。邊界柱破壞情況亦因開口及磚牆構法而異，兩座無開口試體之柱均產生剪力破壞；有開口試體之獨立柱呈現撓曲行為，加強磚造之鄰牆柱發生剪力破壞，而填入式試體之鄰牆柱則為撓曲破壞。比較各試體之最大強度與初始剛度，無開口試體皆高於有開口試體，加強磚造試體皆高於填入式試體，最大位移之趨勢則與最大強度及初始剛度相反。
Abstract	Four full-scale masonry panels in RC frames were tested to investigate the influence of opening and type of masonry panel on in-plane seismic behavior. Test parameters of specimens were construction method and opening condition. Confined masonry panels failed in diagonal tension, and infilled masonry panels failed in bed-joint sliding. Columns of specimens without opening failed in shear, and independent columns of specimens with openings were flexural behavior. Behavior of both columns and panels, and interaction between column and panel are affected by opening condition and construction method. The maximum strength and initial stiffness is higher for confined specimens and specimens without opening, and the maximum displacement has opposite trend.
