摘要
分开裂与未开裂两种状态用应变相容条件计算截面应力与应变 ,以研究钢筋混凝土梁、预应力混凝土梁和部分预应力混凝土梁的统一计算理论。在分析中考虑了混凝土的收缩徐变特性与预应力钢筋的松弛作用 ,并与现行的部分预应力混凝土结构设计规范进行了比较 ,以论证本文理论的正确性与适用性。
A unified approach accounting for the shrinkage and creep of concrete and the relaxation of prestressing steels to analyze RC? PC & PPC structures is discussed by means of stress analysis of uncracked status and cracked status. A comparison between the unified approach and the current design regulations is also presented.
