“…In this context, a great number of recent experimental research findings is available (Turvey and Wang, 2007;Girão Coelho et al, 2015a;2015b), as well as some numerical study on the effect of the joint behavior on the overall structural response (Minghini et al, 2009;.…”

A discussion on some design rules for pultruded fiber-reinforced plastic (PFRP) profiles reported by guideline CNR DT-205/2007 from National Research Council of Italy is presented in the paper. At eight years after approval of this technical document, several changes and improvements are required following recent research findings and supplemental design rules should be incorporated into a future revision. The general framework for the design of columns and beams is outlined. A new closed-form expression for the local buckling moment for beams in majoraxis bending is presented.

“…In this study, the shape functions collected by matrix N a (ξ) = [N a,1 , N a,2 ] are linear Lagrangian polynomials N a,1 1-ξ and N a,2 = ξ, whereas matrix N b (ξ) assembles the "modified" Hermitian shape functions already adopted by Minghini et al (2009;2010;Tullini and Tralli, 2010;Tullini et al, 2013b).…”

“…Furthermore, Shakourzadeh et al (1999) defined a procedure for taking account of the semi-rigid joint deformation of threedimensional thin-walled frames considering membrane, shear, bending, torsion and warping effects. Minghini et al (2009;2010) adopted Shakourzadeh et al's (1999) model for the buckling and vibration analyses of pultruded frames with semi-rigid connections.…”

In the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between structure and substrate in terms of displacements and rotations. To take account of structural nonlinearities, potential plastic hinges are defined at the end sections of the beam elements in the form of semi-rigid connections characterized by a rigidplastic moment-rotation relationship. The incremental analyses carried out emphasize the effectiveness of the model in reproducing collapse mechanisms and stiffness loss of the structure for increasing loads. Moreover, the adopted formulation is able to capture both interfacial shear tractions and vertical normal tractions which develop along the substrate boundary under a variety of loading conditions.

“…An open section thin-walled thermoplastic composite frame segment (sub-element) of a mass transit bus was designed, analyzed and manufactured by Ning et al [25] to replace a conventional metal-based design. Recently, a locking-free finite element formulation for the buckling and vibration analysis of orthotropic fiberreinforced polymers thin-walled frames with open section was introduced by Minghini et al [26][27][28]. A second-order approximation of the displacement field was adopted to account for the shear strain effects on both non-uniform torsion and bending.…”
