Research on the Vertical Bearing Capacity of Light Steel-foam Concrete Composite Wall Frame Column

Using the finite element method to analysis the bearing capacity of light steel-foam concrete composite wall frame column under vertical load. Through the analysis of the bearing capacity of the wall frame columns filled with different grades of foamed concrete under the vertical load, the results of the effect of filled foamed concrete on the bearing capacity of light steel composite wall are obtained. Results show: 1) for the light steel structure with no foamed concrete, the spacing of the wall frame column is increased from 400mm to 600mm, and the axial load bearing capacity is reduced. 2) for the steel foam concrete filled with 12MPa foam concrete structure, the spacing of the wall frame column is increased from 400mm to 600mm, the axial bearing capacity decreases slightly. 3) when the strength of foam concrete is reduced to 8MPa, or increased to 24MPa, the spacing of the wall frame column increases from 400mm to 600mm, the axial bearing capacity decreases first and then increases.
