Abstract

This paper focuses on the development of a new mathematical model and its analytical solution for the analysis of finger-jointed Timoshenko–Ehrenfest glulam beams with interlaminar debonding and finger joint (FJ) flexibility. Consequently, an analytical solution for the mechanical behavior of finger-jointed elastic Timoshenko–Ehrenfest glulam beams with interlaminar debonding and flexibility of FJ is derived. In the illustrative examples, a simply supported Timoshenko–Ehrenfest glulam beam is analyzed, and the analytical results for various kinematic and equilibrium variables are given. Moreover, the parametric study showed that the mechanical behavior of a finger-jointed Timoshenko–Ehrenfest glulam beam is affected by the contact and FJ stiffnesses and the position of the FJ. Moreover, it is proven, that the effect of shear deformation on vertical deflections can be considerable, and can be up to aprroximately 60%.
