Abstract

Abstract

A large-diameter inclined steel-reinforced concrete (SRC) column system is utilized in the underground structure of the Shenzhen Huangmugang comprehensive transportation hub, enhancing both the architectural aesthetics and the transferring comfort while meeting operational requirements. The SRC columns are vertically inclined and have a maximum inclination angle of 13°, and the columns connected to the horizontal beams in the structure, are located outside the beam-beam joints. To investigate the mechanical Properties of the inclined columns, a specimen on a scale of 1/8 was designed and fabricated, and the failure process and response of the column were determined by static test in combination with axial load, shear force, and bending moment. ABAQUS software was employed to further determine the mechanical properties of the inclined SRC column. The results revealed that the horizontal beams and corbels could effectively restrain the lateral deformation of the inclined columns in both directions. The bearing capacity of the inclined columns was 1.62 times the design load, indicating the design was safe and reliable. When the load reached its peak, the in-plane and out-plane lateral displacement was 1/3 046 and 1/3 236 of the length of the inclined column. The concrete in the middle and bottom zone of the upper column region was crushed significantly and the longitudinal steel bar also buckled, and few cracks were observed at the side surface of the corbels.
