| description | To address the issue of stability degradation in truss type high-rise structures caused by material aging, dynamic loads, and extreme environments during long-term service, a multi-level test approach encompassing "material-component-structure" was employed to systematically evaluate the enhancement effects of carbon fiber reinforcement techniques. The test results demonstrate that in material-level tests, sandpaper grinding on the surface of steel truss structures increased the steel/carbon fiber bonding shear strength by 29.98%, outperforming sandblasting and laser treatments. In component-level four-point bending tests, the yield load of reinforced L-shaped beams and joints improved by over 15%, with local strain reductions exceeding 65%. At the structural level, the strain in primary load-bearing components decreased by 28.52%, and the top displacement was reduced by 15.58%, indicating significant improvements in structural stiffness and strength. These findings validate that the proposed reinforcement technique effectively enhances the load-bearing performance of truss type high-rise structures and provides an optimization basis for engineering applications. |
