摘要

摘要: 为改善普通钢筋混凝土梁的抗震性能,提出一种由超韧性混凝土和不同屈服点金属构成的不同屈服点钢筋混凝土梁。基于对不同屈服点钢筋混凝土梁和普通钢筋混凝土梁的低周反复荷载对比试验,对其裂缝发展、破坏形态、滞回曲线、骨架曲线、耗能能力、延性等抗震性能进行系统研究。研究表明,不同屈服点钢筋混凝土梁具有较好的抗震性能。

Abstract: It was put forward a new type of beam consisting of ultra toughness concrete,high strength steels and low yield point steels to improve seismic performance of normal RC beams.Based on contrast experiments of ultra toughness concrete beam with different yield poins steels and a normal RC beam under low reversed cyclic loading,crack propagation,failure pattern,hysteresis curves,framework curve,energy dissipation,ductility,etc.were studied systematically.The studies showed that ultra toughness concrete beam with different yield poins steels had better seismic performance.
