Optimization of reinforcement spacing in CLT panels using the finite element method

Year: 2026

Type: article

Abstract: The paper presents the results of a numerical study on the influence of reinforcement on the structural performance of CLT panels. Numerical modelling was carried out using the finite element method, with anisotropic timber behaviour accounted for. CLT panels with a thickness of 10 cm were analysed; they were reinforced with steel bars at spacings of 10 to 40 cm, while maintaining a constant reinforcement ratio. It was established that reinforcement reduces deflections and longitudinal stresses by nearly half; however, it significantly affects shear stresses in the zones adjacent to the reinforcement. The optimal reinforcement spacing was found to be approximately twice the panel thickness, as this configuration reduces shear-stress concentrations without a considerable increase in labour intensity. Based on the findings, reinforcement is recommended as an effective means to improve the stiffness, load-bearing capacity, and durability of CLT panels in construction applications.
