    • ABSTRACT

    Infill wallswith functions such as the enclosing the building, dividing a large into several small placesthe architectural point of view and providing weather protection for the inside of the buildingare always found in real building. However, in the typical building design, they are always treated as non-structural elements and neglected in the design process.
    In this preliminary study, the effect of RC infill wallon the seismic responses of building was investigated using 2D and 3D single-story frames. The linear analysis was conducted to minimize the factor involved and to avoid the interaction of nonlinear behavior of RC infill wall and frame member. The MIDAS-gen program was adopted for the analysis.
    In this study, the effect of location and area of holes in the wall were examined using 2D single-story frames. The effects of layout of infill walls were investigated using symmetric and asymmetric 3D single-story frames. The use of RC infill wall in 2D and 3D single-story frame can increase the natural frequency as compared with pure-frame model; however the natural frequencies were also affected by the location of hole in the infill wall, and if an extra span with full wall is added, such effect is reduced. Comparison of natural frequency between 2D and 3D frame with and without RC infill wall shows that the frequency in 2D frame is higher than 3D frame; it indicates that 3D frame is more realistic for modeling. In 2D frame the inclusion of infill wall will increase the axial force at column support, while the trend of axial force in 3D-frame is reversed. From the investigation on 3Dsymmetric frame with RC infill wall, it is better to have the walls on both sides of the column to have better reduction in internal forces. On the other hand, the use of RC infill wall at 3Dasymmetric frame can lead to the reduction in the internal force, however the removal of some RC infill walls may lead to the increase in the internal force which maybe become even larger than those of pure frame especially for axial and shear force. Thus, from this studyit is recommended that to study theeffect of RC infill wallon the seismic responses of building 3D model is more realistic.

    摘要

    填充牆主要的功能在包覆建築物讓建築物內部不受到天氣的干擾及分割建築物內部為具不同功能的各種區塊，因此在建築物中經常可以看到填充牆。然而在實際的建築物的結構設計中，填充牆常常被視為非結構元素，在設計的過程中被忽略。
    在本初步研究中，使用2D和3D單層構架探討鋼筋混凝土(RC)填充牆對於建築物的受震反應的影響。本研究僅考慮線性分析，除降低分析時的參數量外，也是避免RC填充牆和構架本身的非線性行為所引致的相互作用。本研究使用Midas-gen程式進行分析。
    本研究中，使用2D構架來探討RC填充牆上開孔的位置和大小的影響；使用3D構架探討填充牆佈置的影響。不論是2D或3D構架，在分析中考慮了RC填充牆會提高自然振動頻率，然而此頻率會受到開孔位置的影響，但隨著開孔率的降低，位置對頻率的影響會減少。此外，2D構架的自然振動頻率會比3D構架來得大。在2D構架中，RC填充牆會增加柱的支承端的軸力，但是在3D構架中卻有相反的趨勢。在柱的兩側最好要同時加填充牆或翼牆來降低構件的內力。在非對稱的構架中，考慮RC填充牆可以降低構件的內力，但是如果移除部分的RC填充牆，則有可能讓某些構件承受比純構架還大的剪力和軸力。因此本研究建議在探討RC填充牆對於建築物的受震反應的影響，最好使用3D模式。
