摘要
通过对无粘结部分预应力砼梁延性性能的试验研究，对影响延性性能的因素如截面配筋情况、跨高比以及加荷方式等进行了分析。
Unbonded partially prestressed concrete(PPC) beams with various reinforcement ratio,different span-height ratio and loading style have been tested to study their ductility,and main factors influencing ductility can be expressed by reinforcement index of section.
