- 中文摘要: 本研究對於預力混凝土梁提出一項合理而實用之設計方法,特別適用於強度控制設計之情況。設計過程計分四步:(1)根據所需之極限強度與韌度選用梁斷面尺寸(包括抗壓鋼筋),(2)依照預力傳遞與工作載重階段之應力要求修正第(1)步選用之斷面;(3)計算所需之預力鋼材及抗拉鋼筋面積;及(4)檢核工作應力以確保設計之合宜。用兩例題說明本設計法之應用,其中一例使用抗壓鋼筋。
- 英文摘要: Presents a rational and practical design method specially adopted to prestressedconcrete beams whose design are governed by strength. The design procedure consistsof 4 steps:(I)Proportioning the beam section, including compression steel, if required, on basis of required ultumate strength and ductility;(2) Modifying the section proportioned in step(I)for the requirements of stresses at transfer and under working load;(3) Computing the required areas of prestressing steel and tension reinforcement, and(4) Investigating the working stresses to ensurs that the design is satisfactory Two numerical examples are illustrated, one of which is designed withcompression steel.
