中文摘要 | 本文之目的係推導一簡單之理論,以分析扭轉作用下之剪力核結構, 首先以溥壁梁理論為基楚,推導出開口斷面剪力核受扭轉作用之理論,並將支撐 梁之作用,考慮成剪力核抗扭轉係數之增加,俾可分析全開口或有支撐梁之剪力 核;而後本文利用轉移矩陣處理並分析具相同斷面成不同斷面組合(厚度可為不均 勻)之剪力核,在各種不同型式之扭矩下,可計算扭轉量、扭轉量導數及應力分 析;最後並以實例分析驗證本法,由本方法所得分析與其他方法比較,其結果相 當一致。 |
英文摘要 | The paper presents a simple theory for torsional analysis of thin-walled shear corestructures. The study of the open-section shear core under torsional load is based on thethin-walled beam theory. For shear core with bracing beams, the beams are treated asreinforcing members to shear core by increasing the value of torsional constants. Transfer matrix technique is used to deal with the shear core having various sections and wallthickness. The presented method is verified by examples. The twisting angles and theirderivatives of the shear cores and the stresses are calculated. Results from the presentanalysis are compared well with those from other methods. |
