“…With the development of production technology, FRP materials exhibit promise in future engineering applications. Unidirectional pultruded FRP profiles (mainly GFRP profiles) are widely used in civil engineering structures such as truss bridges [3][4][5][6], space struc-tures [7][8][9], off-shore and marine structures. With respect to delicate lightweight structures, such as aviation structures [10][11][12], telescope [13], and satellites [14], CFRP profiles are often used as component in those truss type structures.…”

This paper presents an experimental investigation of overall buckling behaviour of carbon fibre reinforced plastic (CFRP) tubes with different off-axis ply orientations. A series of specimens are designed and prepared with stacking sequences [0∘4/±θ∘], with θ corresponding to either 0, 90, 45 or 60. Axial compression tests with effective end-reinforcement and hinge support are performed to investigate the overall buckling behaviour. With respect to the future design and application of CFRP tubes with this type of stacking sequence, column curves for each stacking sequences and all test data are fitted based on Perry-Robertson formula. With respect to the high stress level in the relatively short CFRP tube that facilitates the development of defects, test data present high levels of discreetness. We propose a strategy for engineering safe design in which a reduction factor is added to the original reduction factor based on statistical analysis when the universal slenderness ratio is less than 2.

“…Due to the high strength-to-weight ratio and high stiffness-to-weight ratio, composite materials are ideal applications in the long span and high bearing capacity structures [1][2][3][4][5][6]. Virtually every long span and high bearing capacity composite structure used in spacecraft and civil engineer contains joints.…”

“…However, the load-bearing capacity of these basic techniques is low and they are mainly applied to planar panels rather than tubular member profile [29]. In response to this issue, several new jointing techniques were developed [22][23]30] to address the inappropriate joint designs, which contribute much to the application of FRP materials in heavy-traffic bridges [22][23]30]. A novel jointing technique termed the pre-tightened teeth connection (PTTC) was proposed [31].…”

A hybrid fiber-reinforced polymer (FRP)-aluminum modular space truss emergency bridge has been designed that consists of two triangular deck-truss beams incorporating a new structural form and advanced pultruded FRP profiles. As a fundamental investigation, this paper explores the detailed torsional behaviors of the new triangular deck-truss beam. A full-scale specimen was prepared and tested under pure torsion to evaluate the representative structural performances. A three-dimensional finite element model (FEM) was constructed and validated with experimental results showing good comparisons. Furthermore, the torsional behavior of the triangular deck-truss beam was numerically investigated by removing individual primary truss members to clearly understand the torsional mechanism. It was found that the beam exhibited a specific and unfavorable mechanical behavior prohibiting full utilization of the FRP material' potential. The external torsional moment is primarily resisted by the torsion of the longitudinal profiles and the in-plane bending of the bilateral Vierendeel trusses rather than the out-of-plane bending of the web diagonals. Possible improvement and optimization procedures are further suggested for this beam when solely used as a structure subjected to off-axis load or pure torsion.
