自密实高强混凝土框架结构的抗震性能试验研究

EXPERIMENTAL STUDY OF THE ASEISMIC BEHAVIOR OF SELF-COMPACTING HIGH STRENGTH CONCRETE FRAMES

  • 摘要: 为了保证自密实高强混凝土框架结构在抗震地区应用的安全性,采用MTS伺服加载系统进行了二榀单层单跨框架在拟静力荷载作用下的抗震性能试验研究.在混凝土强度相近、配筋与构件尺寸一样的情况下,对比分析自密实高强混凝土框架与普通高强混凝土框架的抗震性能.在试验中观测了自密实混凝土和普通混凝土框架的裂缝开展情况、破坏过程、结构的荷载-位移滞回曲线、钢筋与混凝土应变等,对自密实混凝土框架结构抗震性能的分析研究可为自密实混凝土框架结构的工程应用提供设计参考.

     

    Abstract: In order to guarantee the safety of self-compacting high-strength concrete frames in earthquake, experiments on two single-story and single-span frames were carried out to study their earthquake resistance behavior. The MTS loading system was used to put the two frames under quasi-static loads. The concrete strength, reinforcement and size of the frames are the same. One of the frames is made of self-compacting high-strength concrete, and the other is made of normal high-strength concrete. Crack developing, failure process, loading-displacement hysteretic curve of the structure and strains of steel bars and concrete are investigated for both frames. Suggestions on engineering application of self-compacting concrete frames are made following the analysis of the earthquake resistance behavior of self-compacting concrete frames.
