Abstract: In order to study the axial compression performance of the ribbed L-shaped steel tube recycled concrete short column, 15 steel tube columns were established for simulation with ABAQUS. The load-longitudinal strain curves of the specimens were analyzed. Simultaneously, many influence factors were studied, including the replacement rate of recycled aggregate, the presence or absence of ribs, the section length-width ratio D/B, the width-thickness ratio B/t, the strength of recycled concrete, and the rib form. The research results show that the changes of width-to-thickness ratio B/t, the strength of recycled concrete, and the section length-to-width ratio D/B have a great influence on the axial compression performance of the tubes, while the replacement rate of recycled aggregate has little effect. In addtion, the addition of ribs can improve the axial compressive ultimate capacity of specimens to a certain extent. The strength of recycled concrete, section length-width ratio D/B, and width-thickness ratio B/t have a great influence on the initial axial compression stiffness of the specimen. With the increased section length to width ratio, strengthened recycled concrete, and reduced steel tube width to thickness ratio, the initial axial compression stiffness increases significantly. The changes of initial axial compressive stiffness of the 15 L-shaped recycled concrete short columns are almost the same, demonstrating a tendency of declining before yielding, and then growing slowly after reaching yield.
