A corrugated plate structure includes a plurality of corrugated plates connected together to form a corrugated structure having a corrugation direction and a cross-corrugation direction. A reinforcement system includes: a first bracket and a second bracket, where the first bracket extends substantially parallel to the cross-corrugation direction and mounted to side-by-side first and second corrugation crests so as to pass over a corrugation valley that joins the first and second corrugation crest, and where the second bracket is spaced in the corrugation direction from the first bracket, and the second bracket extends substantially parallel to the cross-corrugation direction and mounted to the first and second corrugation crests so as to pass over the corrugation valley. An elongated reinforcing member extends substantially parallel to the corrugation direction and mounted to both the first bracket and the second bracket.

The present invention provides a semi-active vibration absorption and energy dissipation control system for restraining vortex-induced vibration of bridges. It has the advantages and characteristics that: (1) springs are horizontally placed at the bottom of a beam, and lengths are not limited, so that the frequency requirement of a low-frequency target can be satisfied; (2) different target frequencies can be realized through different combinations of a plurality of springs connected in series and in parallel, so that multi-order vortex-induced vibration control needs are satisfied; (3) the springs made of fiber reinforced nylon materials are adopted, and are notched, so that a frequency implementation range can be greatly widened; (4) the material and the form of a mass body are not limited, and a water bag can be used, which has low cost and is convenient for disassembly, assembly and mass adjustment.
