AI Technical Summary
Traditional steel-concrete composite structures do not specify the construction method for the connection nodes between steel-concrete composite tubes and beams of unequal heights during installation, which leads to high construction difficulty, large space occupation, and impact on pipeline routes, and the stress on the nodes is unclear.
The structure employs an internally mounted anti-bending steel corbel transition section and an anti-shear stud construction. Combined with the anti-shear steel corbel, it ensures the coordinated operation of the beam-end composite sections. The anti-shear studs connect the unequal-height reinforced concrete beams and steel-concrete composite columns, optimizing the joint form to improve load-bearing capacity and seismic performance.
This method achieves an effective connection between reinforced concrete beams of unequal height and concrete-filled steel tube columns, reducing construction difficulty, minimizing space occupation, and improving the clarity of joint stress and seismic performance.
