Abstract: | 本研究的主題為鋼筋混凝土剪力牆的試驗與分析,試驗目的為比較不同強度材料及相異開口型式之剪力牆的反覆載重行為及裂縫控制研究,因此設計了尺寸、配筋相同的四座剪力牆試體:普通強度未開孔牆、高強度未開孔牆與普通強度開孔牆、以及高強度開孔牆。在實驗後針對彼此的觀測結果互相對比,並以歐洲共同規範CEB-FIP[9]之裂縫模型結合軟化壓拉桿[6,7]建立本研究之尖峰裂縫模型,再以本實驗所歸納的尖峰裂縫與殘餘裂縫寬度比例曲線,將所預測之尖峰裂縫轉為預測殘餘裂縫寬。最後,將殘餘裂縫寬分析值與實驗值以日本建築協會AIJ 2004[10]及AIJ 2010[11]的相關規範做性能評估,並針對評估結果作討論。 The main purpose of this research is about experimental and analysis study of Reinforced Concrete shear wall. The objective of the test is to compare the cyclic loading behavior and the crack width control. The parameters include different strength of materials and openings. This research design four RC wall specimens, normal-strength RC shear wall, high-strength RC shear wall, normal-strength RC shear wall with an opening and the last one is high-strength RC shear wall with an opening. We discuss the observations of the tests, establish a model to predict the peak crack width by combining the concepts of CEB-FIP[9] and Softened Strut-and-Tie model[6,7]. Than we modify the peak crack width to the residual crack width by using experimentally observed ratio between these two widths of this research. Moreover, we evaluate our value of proposed method and experimental data by perspectives the code of Architectural Institute of Japan, AIJ 2004[10] and AIJ 2010[11]. |
