摘　　要：本文从试验、理论及有限元模拟的角度,全面阐述了PVA-钢纤维混凝土的各项力学性能以及PVA-钢纤维构件、节点的受力特点。国内外研究表明,混杂纤维混凝土材料具有明显的应变硬化效应和多细密微裂缝开展特征,改善了单一纤维掺量的混凝土材料只片面提高强度或韧性的缺点;在低周反复静力荷载下,PVA-钢纤维混凝土结构具有良好的耗能能力和抗震性能。From the point of view of experiment,theory and finite element simulation,the mechanical properties of PVA steel fiber reinforced concrete and the mechanical characteristics of PVA steel fiber reinforced concrete members and joints are described in this paper.The domestic and foreign research shows that the hybrid fiber reinforced concrete has obvious strain hardening effect and multiple fine and dense micro cracks,which can improve the strength or toughness of concrete with single fiber content;under low cycle Cyclic Static load,PVA steel fiber reinforced concrete structure has good energy dissipation capacity and seismic performance.
