Study of recycled aggregate concrete-filled circular steel columns with H-shaped steel reinforcement

Jiang Jin et al.

Summary: In this study, the prediction formula for the axial compressive bearing capacity of recycled aggregate concrete-filled circular steel columns with H-shaped steel reinforcement was theoretically studied using the limit analysis method. The bearing capacity of the concrete was divided into two parts, namely the recycled aggregate concrete in the H-shaped steel confined area and the recycled aggregate concrete in the steel-tube confined area, to differentiate the restraining effect due to H-shaped steel and steel tube. The study also investigated the effects of inner diameter-thickness ratio of steel tube, H-shaped steel, and recycled coarse aggregate replacement rate on the column's axial compressive bearing capacity. Eventually, a set of calculation formulas for the axial load bearing capacity of recycled aggregate concrete stub columns with steel tubes and H-shaped steel reinforcement was proposed and validated against test results with an error within 10%, demonstrating the feasibility and accuracy of the proposed formula and the limit analysis method.

Bending restoring force model of angle-steel reinforced concrete columns under combined torsion

Yuliang Chen et al.

Summary: This study tested and analyzed nine angle steel truss reinforced concrete columns (ASRC) under a combined torsion environment to explore the restoring force model. The failure mode characteristics of different component columns were observed and summarized, different failure modes were distinguished, and the hysteresis curve and energy dissipation capacity of component columns were analyzed. A trilinear skeleton curve model suitable for ASRC columns was adopted, and the calculation method of skeleton curves in different stages under the combined action of compression, bending, shear, and torsion was given. The established restoring force model of the ASRC column under coupled torsion was validated by test results, which can predict the hysteretic behavior of ASRC under combined torsion.

Seismic behavior of steel reinforced concrete column with welded studs subjected to combined action of compression-bending-shear-torsion

Ji Zhou et al.

Summary: This paper presents a study on the seismic behavior of steel reinforced concrete (SRC) columns with welded studs. The experimental results show that setting studs at the flange, decreasing stud spacing, and increasing stud length can improve the seismic performance of SRC columns. Additionally, a certain number of structural studs need to be added to enhance the torsional properties of SRC columns subjected to torsion moment.

Experimental study on steel reinforced concrete T-section beam subjected to pure torsion and combined action of bending-torsion

Yuliang Chen et al.

Summary: This paper presents the mechanical behavior of T-section steel reinforced concrete beam under pure torsion and bending torsion. Experimental results showed that the beam exhibited brittle failure in reinforced concrete and ductile failure in steel reinforced concrete, with the flange and steel significantly enhancing the torsional strength and ductility of the specimen. The study also proposed a calculation method for cracking torque and ultimate torque of T-section steel reinforced concrete beam, which is in good agreement with the experimental results.

Experimental seismic analysis of new types of steel-reinforced lightweight concrete columns with cross-shaped steel section

Mostafa M. A. Mostafa et al.

Summary: This paper presents three innovative types of steel-reinforced lightweight aggregate high strength concrete (SRLWAHC) columns subjected to axial compression and cyclic loads. The seismic performance, including failure mode, hysteresis characteristic, ductility, stiffness degradation, and energy dissipation capacity, were explored. The experimental results showed that the new column types exhibited good seismic performance, with the X-shaped steel section performing better than the + shaped section.

Flexural testing for composite members with bolt-connected steel angles

Hyeon-Jin Kim et al.

Summary: The development of a prefabricated steel-reinforced concrete (PSRC) composite column with bolt-connected steel angles improved constructability of large columns. Tests showed good bond resistance between concrete and steel due to bolt assemblies and transverse plates on the steel angles, preventing early bond failure. Despite higher flexural strength, the ductility of PSRC specimens decreased due to stress concentration and tensile fracture at bolt hole locations in the steel angles as inelastic deformation increased.
