“…This stiffness is associated to the parameter αL=1 commonly used in literature to identify the degree of connection of composite beams with partial interaction. For further details of this parameter, see Sousa Jr and Silva (2007). The graph of Figure 10 below shows the variation of the displacement along the composite beam.…”

“…The graph of Figure 10 below shows the variation of the displacement along the composite beam. In this graph, 'reference' refers to the result obtained by Sousa Jr and Silva (2007) and shell9+intshell6 to the result obtained in this work. As it can be seen from Figure 10, the results are practically coincident.…”

“…Considering the possibility of generic cross sections and the physical non-linearity of the cross-section's materials, Silva (2006), and Sousa Jr and Silva (2007), developed an interface element capable of simulating vertical separation and slip at the interface of contact between the materials of the composite section. These interface element works in conjunction with the one-dimensional beam elements implemented considering the EulerBernoulli beam theory.…”

The use of numerical methods such as the finite elements method for solving structural analysis problems is becoming ever more efficient. An interface element capable of associating flat plate/shell element in three different combinations has been developed. In a structural analysis, when only the flat plate/shell's finite elements are used in the discretization, some problems concerning dimensional variation of the transversal section, as well as overlapping of areas can occur. The aforementioned problems can be solved by the developed interface elements that can also simulate a possible deformable connection that is existent in the association of materials with different characteristics, such as the composite steel-concrete elements. One of the applications of the finite elements developed is for the numerical simulation of composite steel-concrete elements, such as the composite beam formed by a reinforced concrete slab attached to a steel beam using a deformable connection. In this case, the concrete slab and the steel beam are discretized by the flat plate/shell element, and the deformable connection done by the interface elements. In the validation of the implemented elements, we used numerical and experimental results found in the literature, and analytical solutions considering the classical plate theory. KeywordsInterface element; flat plate/shell element; composite beam; deformable connection.

“…They account for both materials with their actual position through the composite section. The slip occurring at the steel-concrete interface and resulting from the flexibility of the connection device is either neglected (perfect bond) [16,17] or taken into account [18][19][20][21][22][23][24].…”
