中文摘要 | 本文研究目的有四:(1)預測磚牆之劈裂載重(2)預測磚牆之劈裂位移(3)預測含RC柱梁磚牆之P-△曲線(4)建立含RC邊界柱梁磚牆之恢復力環規則。本文共有12個試體,不同開口方式有中間開門之FBW1、MFBW1試體,開邊門之FBW2、MFBW2試體,上部開60cm高窗之FBW3、MFBW3試體,有110cm窗臺高度之FBW4、MFBW4試體及FBW5、MFBW5、FBW6、MFBW6全砌磚牆試體,其中FBW4、MFBW4、FBW5、MFBW5試體其高×寬為320cm×300cm,其餘試體高×寬皆為320cm×400cm。本文依施力週次多寡區分為兩組:(1)正竑向單週次載重試驗,共6個試體,包FBW1、FBW2、FBW 3、FBW 4、FBW 5、FBW 6。(1)正反向多週次載重試驗,共6個試體,包括MFBW1、MFBW2、MFBW3、MFBW4、MFBW5、MFBW6。 本文先對含RC邊界柱梁磚牆施以正反向之水平力試驗,再以等值牆版模式分析磚牆受力後的行為,並與試驗結果比較獲得強度與剛度之修正係數,以建立磚牆基本力學資訊。其中等值牆版模式之α修正係數用於預測磚牆之勢裂載重;等值牆版模式之β修正數用於預測磚牆之劈裂位多;依位移諧合疊加法可預測含RC邊界柱梁磚牆之P-△曲線。依Taketa Triliear Pinching Model之恢復力環規則,可準確預測含RC邊界柱梁磚牆之多週次正反向來回P-△曲線。 |
英文摘要 | There are four purposes in the paper: (1) to predict the splitting loading of brick walls (2) to predict the lateral displcement of the brick walls at splitting stage, (3) to predict P-△ curves of brick walls with RC boundary elements, (4) to establish hysteretic loops of brick walls with RC boundary elements. There are 12 specimens with different openings. Specimens FBW1 & MFBW1 have a door in the middle. FBW2 & MFBW2 have a door on the side. FBW3 & MFBW3 have a 60 cm high window on the top. FBW4 & MFBW4 have a window of 130 cm high. FBW5, MFBW5, FBW6, MFBW6 are brick walls without any opening. FBW4, MFBW4 & FBW5, MFBW5 are 320 cm high, 300cm wide; the others are 320cm high, 400 cm wide. The 12 specimens are divided into 2 groups. One subject to 1 cycle of reversed loading. Such as FBW1, FBW2, FBW 3, FBW 4, FBW5, FBW 6. the other subject to mutiple cycles of reversed loading. Such as MFBW1, MFBW2, MFBW3, MFBW4, MFBW5, MFBW6. After testing the reversed horizontal loading of brick walls with RC boundary elements, the behavior of the specimens is analyzed by using an inplane plate model. The strength and stiffness modified coefficient is obtained to help study the basic mechanics of the brick walls. In the equitvalent in-plane late model, the coefficient αcan be used to predict the splitting loading of brick walls; the coefficient βcan be used to predict the lateral displacement of brick walls at splitting stage. Based on the consistence of displacement, the P-△ curve of brick walls with RC boundary elements can be predicted. With the hysteretic loop rule of Takeda Trilinear Pinching Model, P-△ curve of multi-cyclic loading can be precisely predicted. |
