ISO/TR 21136:2017 PDF Download

ISO/TR 21136:2017 is a standard that provides a comprehensive review of vibration performance criteria for timber floors. It summarizes the findings of various research studies conducted over the past 30 years and presents design methods for determining human acceptability criteria for timber floor vibrations caused by walking activities.

The standard covers different types of timber floors including lightweight floors made of timber joists and thin wood panel subfloors, heavy timber floors made of heavy timber beams with a thick timber deck, and mass timber slab floors such as cross laminated timber (CLT), nail laminated timber (NLT), and glued laminated timber.

The goal of ISO/TR 21136:2017 is to establish guidelines that ensure acceptable levels of vibration in timber floors, thereby enhancing the comfort and safety of occupants. The standard serves as a valuable resource for designers and engineers involved in the construction and evaluation of timber structures, offering reliable methods for assessing floor vibrations and determining their impact on human occupants.
