摘要
钢筋混凝土板柱结构具有节约净空、平面布置灵活及施工方便等优点,是常见的建筑结构体系。但板柱结构节点区受力复杂,目前对其传力机制和破坏机理尚未有统一的认识,板柱节点的冲切破坏问题尤其突出。根据文献对钢筋混凝土板柱节点的破坏形态进行了总结,并根据相关研究成果归纳了板柱节点破坏形态的判别公式及应用条件;梳理了影响板柱节点抗冲切性能的主要因素,并对相关研究现状进行了综述,指出了进一步研究的方向。
Reinforced concrete slab-column structure has the advantages of saving headroom,flexible floor layouts and convenient construction.It is a commonly used building structure system.However,the slab-column joint area is subject to complex forces.At present,there is no unified understanding of its force transfer mechanism and failure mechanism.Punching failure of slab-column joints is a particularly prominent problem.The failure patterns of slab-column joints are reviewed according to related literatures.The discriminant formulas of failure modes of slab-column joints and the application ranges are summarized based on existing studies.The main factors influencing the punching resistance of slab-column joints are sorted out,and the related research status is reviewed.The directions for further research are pointed out.
