AI Technical Summary

Technical Problem

The existing corrugated web of the corrugated steel beam has insufficient stability, and the connection between the concrete and the corrugated steel beam is unstable, which affects the overall strength and seismic performance of the composite beam.

Method used

The design employs a reinforcing rib, which is welded between the corrugated web and the flange steel plate. Concrete and steel reinforcement are then poured through perforations to form a stable corrugated steel beam structure, thereby improving tensile, compressive, and shear bearing capacity and enhancing the connection stability between the concrete and the steel beam.

Benefits of technology

It improves the overall stability of corrugated steel beams and the strength and stiffness of concrete composite beams, enhances seismic performance, and reduces material costs.
