摘　　要：以已有试验数据为基础,分析了配HRB500级钢筋部分预应力混凝土梁在静力荷载作用下的刚度和变形的特点,提出了相应的计算方法。明确了HRB500级钢筋用于预应力混凝土结构中的刚度计算方法。探讨了配HRB500级钢筋部分预应力混凝土梁的延性特点及影响延性的因素。为配高强钢筋的预应力混凝土结构设计和刚度变形计算提供了一定的参考。Based on the existing experimental data,stiffness and deformation characteristics of partially prestressed concrete beams equipped with HRB500 high-strength reinforcement under static loading were analyzed and corresponding calculation method was put forward. Stiffness calculation method of prestressed concrete structure equipped with HRB500 high-strength reinforcement was clarified. The characteristics and influence factor of ductility of partially prestressed concrete beams equipped with HRB500 high-strength reinforcement were discussed. Some references for the distribution of high strength steel prestressed concrete structure design and stiffness calculation were provided.
