- 中文摘要: 鋼筋混凝土梁內使用抗壓鋼筋者有六種情形。依照使用情形其設計可分為三類不同方法:如(1)強度控制之雙筋梁(2)長期撓度控制之雙筋梁;(3)已知A' s之雙筋梁一抗壓筋之使用非因強度或撓度之需要“本文對此三類每類提供一個新設計方怯並各舉一例說明之。設計方法既合理,經濟且嚴格遵守AG1318一71規範之規定。
- 英文摘要: Reinforced concrete beams with compression steel are used in six cases.They may be designed by three different methods according to their usages:such as doubly reinforced concrete beams for strengrh requirement; (2)doubly reinforced concrete beams for deflection control; and (3) doublyreinfored concrete beams with known A's---一一Compression steel are usednot for strength and deflection. This article presents each of the threecategories a new design method and illustrated with an example. Thedesign methods are rational and economical,and are strictly based on theprovisions of ACI 318-71.
