文摘

The test specimens are manufactured with high strength concrete (C100) and high strength steel (Q460). The effects of steel ratio, yield strength and concrete compressive strength are considered. The proportion of bear the bearing capacity of each component is studied by finite element analysis. Different codes are used to calculate the ultimate bearing capacity of the test specimens and FEA models.
