“…Fiber-reinforced plastic (FRP) truss structure has been used in structural engineering because of its high strength, low density, and good corrosion resistance (Bai and Zhang, 2012; Chen et al, 2022; Teixeira et al, 2014). Although FRP profiles have excellent tensile properties along the fiber direction (Chin et al, 2015; Feng et al, 2022; Rodsin et al, 2020), their compressive properties were poor (Higgoda et al, 2023), so they could not be directly used in the compression bars of truss structures.…”

To solve the instability of the compression bars in the space truss composed of GFRP tubes, a composite column with high-strength concrete (HSC) confined by glass fiber-reinforced plastic (GFRP) tube was proposed. High-strength self-compacting micro-expansive concrete with a slump greater than 255 mm was produced under normal-temperature curing conditions and confined by GFRP tubes. A mechanical performance test of the GFRP-confined HSC short column under axial compression was performed. The effects of GFRP tube types, concrete expansion agent, constraint effect, ultimate load capacity, and failure mode of the composite structure were discussed and analyzed through the test. A model of the stress-strain response of the GFRP confined HSC column was proposed. The results show that the 45° fiber-wound GFRP tube has a significant restraining effect on the HSC. The stress-strain relationship increases quadratically in a linear fashion. When the composite column was damaged, the GFRP fiber was broken and the concrete was crushed. The ultimate strength was about 1.5 times that of unconstrained HSC columns, and the loading method has less influence on the results. The expansion agent has a significant effect on the deformation performance of the composite column, and its ultimate strain was about 1.4 times that of the composite column without expansion agent.

“…Industry sectors such as automotive, aerospace, marine, etc., have utilized these advantages to achieve significant breakthroughs in performance and design [ 2 , 3 , 4 ], and the construction sector was inspired by these achievements to use FRP materials to enhance structural performance, durability and safety of civil engineering structures [ 5 , 6 ]. For instance, FRP materials were used in truss bridges [ 7 ]. However, FRP materials have hierarchical structures consisting of multiple materials, and their complicated manufacturing processes inevitably introduce uncertainties in material properties, geometrical parameters, etc.…”

This study introduces a Radial Basis Function-Genetic Algorithm-Back Propagation-Importance Sampling (RBF-GA-BP-IS) algorithm for the multi-scale reliability analysis of Fiber-Reinforced Polymer (FRP) composite structures. The proposed method integrates the computationally powerful RBF neural network with GA, BP neural network and IS to efficiently calculate inner and outer optimization problems for reliability analysis with hybrid random and interval uncertainties. The investigation profoundly delves into incorporating both random and interval parameters in the reliability appraisal of FRP constructs, ensuring fluctuating parameters within designated boundaries are meticulously accounted for, thus augmenting analytic exactness. In application, the algorithm was subjected to diverse structural evaluations, including a seven-bar planar truss, an architectural space dome truss, and an intricate nonlinear truss bridge. Results demonstrate the algorithm’s exceptional performance in terms of model invocation counts and accurate failure probability estimation. Specifically, within the seven-bar planar truss evaluation, the algorithm exhibited a deviation of 0.08% from the established failure probability benchmark.
