The steel-concrete composite structure combines the advantages of steel tensile strength and concrete compressive strength, and is widely used in high-rise buildings and bridge engineering.
The global annual production of construction solid waste is enormous, and resource utilization is the key to achieving sustainable development.
Replacing some of the aggregates in the core concrete of steel tube concrete with building solid waste concrete blocks is a new way to achieve high-value utilization of solid waste.
However, the influence of different replacement rates of solid waste concrete blocks and combinations of steel pipe diameter to thickness ratios on the axial compression performance of components is not yet clear, and the applicability of design specifications also needs to be verified.
