Abstract

In order to enhance the utilization of coal gangue as solid waste, this study investigates the axial compression performance of medium-length columns composed of square steel tubes filled with coal gangue concrete. A finite element model was developed using ABAQUS software to analyze the impact of parameters such as coal gangue aggregate replacement ratio on the load-bearing capacity of the specimens. The results indicate that the compressive strength of coal gangue concrete and the steel content are key factors affecting axial load-bearing capacity. When the coal gangue aggregate replacement ratio increased from 0 to 100%, the reduction in axial load-bearing capacity of the specimens was within 9.9%. Therefore, the incorporation of coal gangue aggregate has a minimal impact on the load-bearing capacity and meets engineering requirements.
