“…Furthermore, use of these materials may lead to a heavy sacrificial structure. On the other hand, composite materials have relative advantages in terms of specific energy absorption, weight and maintenance [6,7]. Hence, in this research composite tubes have been chosen for the inner core of the sacrificial cladding structure (refer Figure 1).…”

This paper presents the quasi-static crushing performance of nine different geometrical shapes of small-scale composite tubes. The idea is to understand the effect of geometry, dimension and triggering mechanism on the progressive deformation of small-scale composite tubes. Different geometrical shapes of the composite tubes have been manufactured by hand lay-up technique using uni-directional E-glass fabric (with single and double plies) and polyester resin. Dedicated quasi-static tests (144 tests) have been conducted for all nine geometrical shapes with different t/D (thickness to diameter) ratios and two triggering profiles (45 ⁰ chamfering and tulip pattern with an included angle of 90 ⁰ ). From this unique study, it was found that the crushing characteristics and the corresponding energy absorption of the special geometrical shapes are better than the standard geometrical shapes such as square and hexagonal cross sections. Furthermore, the tulip triggering attributed to a lower peak crush load followed by a steady mean crush load compared to the 45 ⁰ chamfering triggering profile which resulted into a higher energy absorption in most of the geometrical shapes of the composite tubes.

“…However, this is less likely to be the case in the same assembly with circular GFRP as is expected that there will be minimal contact between the shear connectors and GFRP. Some studies have focused on the workability of adhesive connections in mutually connected FRP (Gonilha et al, 2014;Green & Phillips, 1982;Hagio et al, 2003;Hollaway et al, 1990;Keller & Gürtler 2006;Keller et al, 2007;Kostopoulos et al, 2005;Pickett et al, 1982). Small-scale FRP composite space frame structures were investigated as far back as 1982 where Green and Phillip suggested a crimp-bonded joint for circular FRP pultruded sections bonded with alloy using a structural adhesive paste (Green & Phillips, 1982).…”

This paper reports on a new experimental study for the behaviour of reciprocally connected and supported Fibre Reinforced Polymer (FRP) hollow square profiles axially loaded under several boundary conditions. The study aims to determine the ultimate load of the assembly and failure mechanism of mutually connected units. For the tests, FRP reciprocal frames units (RF) of 100 × 100 × 6.4 mm thick square hollow sections were designed, fabricated and assembled using mechanical fasteners. A bespoke steel test rig allowed for varied support boundary conditions. The observed failure modes were dominated by web buckling, bearing failure around the bolted areas and localised failure. The 100 × 100 mm RF unit achieved the highest load capacity of 16.4 kN and frame stiffness of 1.7 kN/mm, under the pin-pin-roller support boundary conditions. This paper presents the experimental procedure, results and observations.

“…FRP truss bridge which can make full advantage of high specific strength and stiffness along fiber direction of FRP materials has been widely recognized by researchers at home and abroad. There are many successful engineering cases, such as Swiss Pontresina bridge [1] , Danish Kolding bridge [2] , Japanese Iwao Sasaki bridge [3] and Greek Kostopoulos bridge [4,5] . using FRP section extrusion on structural members which connected by traditional glue, bolt or metal plate with bolts.…”

A composite-metal hybrid assembling stringed truss bridge which based on pre-tightened tooth connection can make full use of the strength of the FRP fiber in the direction of the fiber, and is of higher bearing capacity than the FRP truss bridges with traditional adhesive or bolt connection. However, whether the calculation method of FRP truss bridge with traditional bondingor bolt connection is suitable for this new type of bridge needs to be researched because of the difference on the structural form and connection mode. In order to obtain the suitable method of this kind of bridge, a new method for calculating live load deformation which consider the influence of end of the steel bar sleeve of rod stiffness was established in this paper; the deformation experiment of truss bridge was carried out. The experiment and calculation results show: compared with the calculation method of the live load deformation of the traditional FRP truss bridge, the calculation method of live load deformation considering the effect of the steel sleeve on the end of the rod is in good agreement with the live load deformation obtained by the experiment; the calculation method of inelastic deflection has also been verified by the experimental results.
