    Abstract: 鋼筋混凝土建築物因考量居住性及機能性的問題,填充牆時常被用於建築物內,材料較多為磚塊組合成的,但是在結構物設計時,通常填充牆不被視為對結構影響的結構元件,所以整體分析時忽略其在結構物內的分佈,以避免複雜的計算,並簡化分析。
    這一初步研究的目的是探討利用宏觀模型(桿狀型),考慮單層單跨鋼筋混凝土框架結構,用於分析有不同填充牆的開孔分佈比較其結果與使用的微觀模型(牆元素模型)對結構物整體地震反應的差別。數值模擬是用軟件MIDAS / GEN進行。
    ;For functional reasons, infill walls are used in reinforced concrete building and masonry is a material commonly used for such infill walls. In design and analysis, usually masonry infill walls are not considered as structural elements and their influences on the structural responses are ignored to avoid complicated calculations and to simplify analyses.
    The objective of this preliminary study is to investigate the suitability of using macro model (strut model) for analyzing the seismic responses of single-story single-span reinforced concrete frames having different arrangement of masonry infill wall with openings by comparing its results with those using micro model (wall-element model). The numerical simulations were conducted using software Midas/GEN.
    The infill masonry wall increases the stiffness of RC frame structure, as compared with pure frame model. Meanwhile, the diagonal strut model will give smaller natural frequencies than wall-element model based on the formula and modelling technique used in this study. When the part of the wall opening causes the wall to have no contact with a column, short column effect will be introduced in the column. When the height of infill wall becomes smaller, the short column effect will become smaller. Wall-element model can predict better the short column effect than the strut model. Although under static lateral load replacing masonry infill wall by diagonal strut was considered to be suitable for computing the response structure behaviour for the case without any opening in infill wall, it is not the case for the dynamic analysis. In some cases much higher values can be obtained using the strut model. Basically, variation of infill width does not affect structure response significantly in partial width model. The different forces can be observed only in the part of infill wall having contact with frame element.
