摘要
Two different specimens of hollow composite columns with perforated ribs, one is the column with double steel skin and the other is with single steel skin, were designed for imposing axial compression test The tests indicated that both of the columns have a good bearing capacity and the column with double steel skin has a comparatively better bearing capacity than the one with single steel skin. Then comparisons between tests and finite element analysis (FEA) were preceded, which showed that not only the load-displacement relationship of the columns, but also a reasonable failure mode can be simulated by the finite element analysis.
