摘　　要：在砖柱表面外包钢板形成钢板-砖砌体组合柱,可以大大提高原有砌体的承载力、延性与外包钢板的屈曲性能。本文通过已有钢板-砖砌体组合短柱轴压静载试验及有限元模拟,分析钢板-砖砌体组合短柱的工作机理。基于钢管混凝土及薄板局部屈曲理论,提出钢板-砖砌体组合短柱局部屈曲临界应力的计算方法,并对影响钢板局部屈曲的若干因素进行探讨。The axially compressive bearing capacity,as well as the local buckling behavior and the ductility may be further enhanced,by bonding steel plate around masonry column. This article is to acquire the bearing mechanism of steel plate plate-masonry composite column via the axially compressive static tests of 6 steel plate-masonry short column specimens and finite element method. Based on the theory of concrete-filled steel tube column and the energy method,the calculation formula of the critical local buckling stress for this kind of composite column has also been deduced,some factors influencing the local buckling behavior also has been analyzed.
