“…These aspects can involve instability of the structure, which being very complex require unconventional computational methods (see, e.g., [67][68][69][70]). It is worth investigating the use of the Generalized Beam Theory in order to model in a more accurate way the fibers, in particular taking cross section distortions into account (see, e.g., [71][72][73]). Finally, the possibility to equip the structures treated with appropriate transducers may allow structures that can be used as smart sensors to be conceived (see, e.g., structures equipped with discrete [74][75][76] or diffuse [77] piezoelectric transducers).…”

The aim of the present paper is the analysis of a two-dimensional continuum with two families of inextensible fibers that are orthogonal in the initial configuration. In the first part of the work, a new formulation is presented, in which the problem is reduced to a standard nonlinear constrained minimization, while in the second part of the work several numerical investigations are presented considering different boundary conditions with respect to standard symmetric bias extensional tests. The conceptual framework can be recognized in the researches by Pipkin and Rivlin on inextensible nets. Furthermore, an implicit version of the Rivlin representation of the generic placement for a two-dimensional sheet with two families of inextensible fibers is provided by considering the angles of the fiber directors as degrees of the freedom of the formulation. In this way the first gradient formulation is given in terms of two angle fields only.

“…Simplified methods based on standard beam or grillage models [2,3] usually offer a simple approach, but they may lead to insufficiently accurate results especially if flexible intermediate bracings are present and their effect needs to be properly considered. Alternatively, Generalized Beam Theory (GBT) can be employed [4][5][6][7][8][9][10]. Originally proposed and developed by Schardt [11], GBT is currently well established as a powerful tool for the analysis of thin-walled prismatic members with deformable crosssections, since it (i) retains (and improves on) the structural interpretation of a beam formulation and (ii) provides very accurate results with just a fraction of the computational effort required by full shell finite element models.…”

Effect of Cross‐section Bracing in Steel‐concrete Composite Bridge Decks Using the Generalized Beam Theory

et al. 2023

This paper explores the structural analysis of steel‐concrete bridge decks with explicit consideration of flexible cross‐section bracing, using a novel procedure based on the Generalized Beam Theory (GBT). The effect of the bracing is included in a GBT‐based bar finite element, which is used to analyze two numerical examples involving standard deck cross‐sections and bracing systems. It is shown that the proposed finite element leads to extremely accurate solutions when compared with those obtained with full shell finite element models, with a huge economy in terms of DOFs. Moreover, it is shown that the modal features of GBT provide a very valuable tool for the structural interpretation of the results.
