摘要
本文通过两榀框架梁按不同预应力度配置无粘结预应力筋和非预应力筋的“强柱弱梁”型无粘结部分预应力混凝土框架在水平低周反复荷载作用下的试验研究 ,探讨其包括裂缝分布、破坏形态、极限承载力、无粘结筋应力变化、位移延性、耗能能力、恢复力特性等工作性能 ,并进一步分析了影响此类结构抗震性能的主要因素 ,为无粘结部分预应力混凝土框架在地震设防区域的应用提供参考。
Based on the experiments of two single-span,single-story,partially prestressed concrete frames with unbonded tendons under horizontal-low-cyclic loading with constant vertical loading, which just have different partially prestressed ratio in beams, this paper inquires into the cracks distribution, damage state, the ultimate capacity, the stress of the unbonded tendons, ductility features, the energy-dissipating capacity and the hysteretic characteristics etc. Furthermore, the main factor of aseismic properties of the structure is also discussed in this paper.
