Resumo
Multilayered partially connected beams are present in many structural applications, such as the classic composite steel-concrete beam (2 layers), the newly developed bi-steel panels (3 layers), as well as timber beams composed by several layers glued or connected by mechanical devices. The main characteristic of these elements is the allowance for relative displacements between the layers, which is usually termed as partial interaction, incomplete interaction or interlayer slip. Finite element solutions for these kinds of problems have been developed for some time and the classic Euler-Bernoulli as well as Timoshenko beam models are the most employed. It is well known that these kinds of beams are prone to slip locking for some interpolation schemes. The purpose of this work is to present the formulation for the numerical linear analysis of multilayered composite beams and to perform a comparative study of the quality of the response of some finite elements specifically designed to solve this problem.
