摘要
区域约束混凝土是在约束混凝土研究基础上提出的新概念。由于约束机制改变,区域约束混凝土与普通约束混凝土有着不同的力学性能及破坏形态。采用区域约束,使得约束效率提高、构件的受力性能改善,加上特殊的破坏形态,使得构件的可靠度更高,结构的抗震性能更好。
Regional confined concrete is proposed based on the research of confined concrete. Comparing with normal confined concrete, the mechanical property and failure mode of regional confined concrete are different due to the change of the way of confinement. With regional confinement, the confinement efficient and mechanical property of element are prompted. Additionally, the special failure mode increases the reliability of structures and anti-seismic capacity.
