論文中文摘要:鋼鋼筋混凝土牆在現今的鋼筋混凝土建築物中相當的常見,其力學行為不僅是在高強度抗剪能力的貢獻,還有對於梁、柱圍束力的影響。在結構分析中,有時候會忽略牆板對於結構物的影響,而只針對梁柱的力學行為作探討。鋼筋混凝土牆之所以有時候被忽略,是因為它進入非線性階段時,無法用簡單的數理邏輯來呈現其複雜力學行為與特徵。
在目前的地震工程學術領域中常用的分析程式OpenSees可以取得鋼筋混凝土牆的元素中,本研究針對multi-layer shell element與cyclic softened membrane model的理論背景初步了解,並且以鋼筋混凝土牆的測試探討兩種元素在力學行為上的差異與趨勢。本研究與實驗比較的對象是在2015年3月和2016年1月國家地震工程研究中心各進行了一次縮尺圍阻體的反覆側推實驗。由於截至2016年12月OpenSees所提供的cyclic softened membrane model只能進行二維結構分析,所以本研究僅使用multi-layer shell element模擬兩次的縮尺圍阻體反覆側推實驗。在本研究導入cyclic softened membrane model的理論,調整原始的multi-layer shell element模型參數,藉此我們得到不同條件下的分析成果,最後比較與探討兩種分析成果的力學行為。
論文英文摘要:Reinforced concrete (RC) walls are generally applied in currently RC structures. They not only contribute high shear capacity to the structures but also give confinement on neighboring beams and columns. In practical structural analysis, the mechanical behaviors of beams and columns are considered in numerical models, but the influence of walls are sometimes ignored. It is not easy to define the complicated behaviors and characteristics of reinforced concrete walls by simple mathematics and logics, especially when it gets into highly nonlinearity. That is why the influence of reinforced concrete wall is commonly reduced to simple numerical models in practices. However, simple numerical models do not represent complicated failure mechanisms of reinforced concrete walls.
This research employed multi-layer shell element (MLSE) type and cyclic softened membrane model (CSMM) element type to simulate reinforced concrete walls, and discussed their differences by a series of numerical tests. The parameters for the MLSE were adjusted according to the CSMM numerical results. Since the CSMM was applicable only for 2D problems (up to December, 2016), it was not further employed for 3D tests in this work. Two reduced-scale reinforced concrete containment vessel tests, which were conducted in 2015 and 2016, respectively, were adopted to investigate the MLSE behaviors when it is used to model a tubular RC structure. The analysis results under different conditions were presented in this work. Finally the mechanical behavior of both analysis results are compared and discussed.
