Implication

Randomized trial evaluates CFRP reinforcement's impact on load performance and energy absorption in steel truss bridges, indicating enhanced durability.

Key Points

This research aims to assess the effectiveness of CFRP sheets in enhancing load and energy absorption performance in steel truss bridges.
Conducted cyclic loading tests on short steel specimens with rectangular and H-shaped cross-sections reinforced with CFRP sheets.
Applied axial tensile and compressive forces during testing to evaluate performance under load conditions.
Measured improvements in load capacity and energy absorption properties of reinforced specimens.
CFRP reinforcement significantly improved load capacity and suppressed out-of-plane displacement.
Delays in buckling behavior were observed during cyclic loading tests, indicating enhanced deformation performance.
