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. Basing 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.Keywords: steel plate; masonry; axially compressed; local buckling; energy method
