Abstract

In this paper, a simplified model of a generic Phoenix canariensis structure with regard to its resistance to external forces is proposed. The model allows estimation of the maximum admissible wind load on the palm structure, on the basis of tissue resistance, the presence of decay areas, and the particular geometry and stiffness of the stem and the upper crown, which causes a significant reduction of the resistant area when wind speed is increased. The model is applied to a P. canariensis palm, on which physical and mechanical tests were carried out. In particular, on the basis of the experimental tests on some trunk specimens, the modulus of rupture (MOR) and the modulus of elasticity (MOE) of the palm stem under test are calculated, taking into account the variations in mechanical properties along the stem height. In view of both the complex behaviour of palms under wind loads and the uncertainties in the stem MOR calculation, the figures provided in this paper should only be regarded as preliminary, while more in-depth research and experimental analysis are needed. Nevertheless, the findings in this paper could provide useful guidance to practitioners.
