中文摘要 |
台灣地區地狹人稠,可利用之建築面積已逐漸減少,因此建築物朝使用高強度鋼筋混凝土,建造超高樓層建築是必然趨勢。然而實務上,柱常因開孔之需要而形成短柱。故短柱之剪力強度預測至為重要。根據實驗顯示,短柱剪力破壞為對角壓桿端部之混凝土擠碎,故建議使用軟化壓拉桿模型,來預測高強度鋼筋混凝土短柱之剪力強度。本文採用日本之測試結果作驗證,發現建議模型之分析結果偏保守,但符合試驗之破壞機制。日本建築學會(1990)規範與New RC計畫之柱剪力強度評估公式在本文中亦透過測試結果加以驗證,其分析結果合理,但以New RC計畫公式之破壞機制較為符合實驗結果。 |
英文摘要 |
The usable land is quite limited in Taiwan now, so that the construction of ultra high-rise residential building using high strength reinforced concrete materials is inevitable. In practice, short columns are often resulted due to openings and their shear strength prediction is very important. Observation from experiments shows that shear failure of short columns is caused by concrete crushing at the ends of diagonal strut. Therefore, in this paper, it is suggested to use Softened Strut-and-Tie model to predict the shear strength of short columns using high strength materials. Reasonable predictions can be obtained by the proposed model as compared to the test results from Japan. In this paper, the shear strength formulas of Architectural Institute of Japan (1990) and New RC project were evaluated by the test results. Their accuracy and predicted failure mechanism were also reported. |
