To achieve light weight, high load-carrying capacity, and corrosion resistance, a novel hybrid FRP-aluminum space truss system is proposed in detail. An advanced pretightened teeth connection (PTTC) its combined joint–aluminum bolt–ball connecting (ABCS) were designed to interconnect pultruded FRP elements. In view of the significant effect ABCS on structural deformation, axial stiffness properties first investigated through experimental tests numerical simulations. Then, establishing...
In the conventional methods, shear failure load of composite pretightened tooth connections is determined by experiment. To determine connection without performing experiments, a method based on characteristic lengths presented in this paper. This involves three steps: first, are determined; second, stress distribution joint analyzed use finite element method; finally, predicted length and criterion. The loads validated test results for joints with different parameters. comparison...
A new glass fiber-reinforced-polymer (GFRP)–metal box-truss composite girder was developed for use in lightweight deployable vehicular bridges with favorable torsional resistance large spans. This paper describes the experimental characterization of static behavior latest structure characterized by a closed cross section, comparative study on an early version having open section. The structural form differed considerably from that version. Nondestructive tests symmetrical and unsymmetrical...
The study focused on examining the flexural failure behavior of a newly developed assembled FRP-Steel pre-tightened teeth connection (PTTC) used for rapidly assembly pultruded fiber reinforced polymer (FRP) tubular beams. Four-point bending loading tests were conducted specific type joint that incorporates PTTC and threaded connections. results indicated each component demonstrates typical with desired load-bearing capacity. FRP-steel exhibits gradual occurrence various modes, which differed...
This paper investigates geometrical effects on the load transfer mechanism of off-ground capped pile groups subjected to vertical by four three-dimensional numerical simulations, including a circular single pile, an X-shaped cross-sectional concrete (XCC) 4 × group, and XCC group. The ultimate bearing capacities piles within are approximately 0.86 0.74 times that piles, respectively. group efficiency is mainly improved its side resistance. Comparing increment in resistance almost larger than...
A novel foam core sandwich structure was proposed to prevent skin wrinkling by inserting glass fibre-reinforced plastic stiffeners attached the skins. modified vacuum-assisted resin infusion method used manufacture panels. To investigate in-plane compression strengths and failure modes of new panels, experimental tests were performed on a series specimens with different cross-sectional configurations, including thin skin, thick stiffened ones. In addition, analytical modelling conducted,...
A new glass fibre-reinforced polymer–metal structure with a string box-truss girder was designed as vehicular emergency bridge. The bridge is intended to be lightweight, structurally sound, long span and modular feasibility, associated faster construction bridging system. In this study, the detailed conceptual design of described first. large-scale static bending loading test carried out on fabricated examine its actual flexural performance under serviceability limit state. experimental...
Abstract This paper presents an experimental investigation of overall buckling behaviour carbon fibre reinforced plastic (CFRP) tubes with different off-axis ply orientations. A series specimens are designed and prepared stacking sequences [0 ∘ 4 /± θ∘ ], θ corresponding to either 0, 90, 45 or 60. Axial compression tests effective end-reinforcement hinge support performed investigate the behaviour. With respect future design application CFRP this type sequence, column curves for each all...
To realize lightweight and corrosion resistance, a novel hybrid pultruded fiber-reinforced polymer (PFRP)-aluminum space truss system is proposed, which adopts the pretightened teeth connections (PTTCs) aluminum–bolt–ball connecting (ABCS). The diagonal chord members of are joined by ABCSs to form free-form truss. identify possible failure modes, reveal bearing mechanism, investigate suitable design methods, compression experiments were separately conducted on two square pyramid...
For emergency purposes, a lightweight space truss bridge was designed. The is composed of twin triangular deck-truss beams incorporating new structural forms and advanced fiber-reinforced polymer profiles. As structure, the properties its beam have been studied in detail; however, design-oriented study facilitating application entire twin-trackway under pure torsion remains to be undertaken. objective this article analytically explore torsional mechanism bridge, which characterized by angle...
