“…In the last few years, new civil engineering designs have emerged in the field of the construction of footbridges, considering new materials [1,2] and constructive [3][4][5] solutions. Within these new materials, have received special attention the use of fiber reinforced polymer (FRP) and glass fiber reinforced polymer (GFRP), offering better resistance to environmental agents and the advantages of high stiffness-to-weight and strength-to-weight ratios when compared to conventional construction materials [6,7].…”

Experimental and numerical approaches for structural assesment in new footbridge desings (SFRSCC-GFPR hybrid structure), Composite Structures (2015), doi: http://dx. AbstractWithin the civil engineering field, the use of the Finite Element Method has acquired a significant importance, since numerical simulations have been employed in a broad field, which encloses the design, analysis and prediction of the structural behaviour of constructions and infrastructures. Nevertheless, these mathematical simulations can only be useful if all the mechanical properties of the materials, boundary conditions and damages are properly modelled. Therefore, it is required not only experimental data (static and/or dynamic tests) to provide references parameters, but also robust calibration methods able to model damage or other special structural conditions. The present paper addresses the model calibration of a footbridge bridge tested with static loads and ambient vibrations. Damage assessment was also carried out based on a hybrid numerical procedure, which combines discrete damage functions with sets of piecewise linear damage functions. Results from the model calibration shows that the model reproduces with good accuracy the experimental behaviour of the bridge.

“…The trusses can be biconcave or biconvex where the upper and lower truss chords are connected by elements subject to tension in the former and compression in the latter [2]. Various biconcave truss footbridge configurations have been proposed and evaluated statically [5,6] and dynamically [7,8]. Discrete rope stays (i.e., guys) may be used instead of a rope truss to stiffen a bridge.…”

“…The simplified method assumes that the load acts uniformly along the span of the main cable, which follows a parabolic shape [2,17,19]. To account for a cable's sag effect, Ernst proposed the equivalent modulus of elasticity for a parabolic cable [20].…”

Featured Application: An improved analytical algorithm has been successfully applied in shape finding during design and configuration control during construction of main cable system for suspension bridges.Abstract: This paper develops an improved analytical algorithm on the main cable system of suspension bridge. A catenary cable element is presented for the nonlinear analysis on main cable system that is subjected to static loadings. The tangent stiffness matrix and internal force vector of the element are derived explicitly based on the exact analytical expressions of elastic catenary. Self-weight of the cables can be directly considered without any approximations. The effect of pre-tension of cable is also included in the element formulation. A search algorithm with the penalty factor is introduced to identify the initial components for convergence with high precision and fast speed. Numerical examples are presented and discussed to illustrate the accuracy and efficiency of the proposed analytical algorithm.
