该欧洲标准规定了用于确定木材或木材复合梁和地板系统的基频，阻尼，单位点载荷挠度和加速度的测试方法

This document specifies test methods for the determination of natural frequencies, damping, unit point load deflection and acceleration of floors composed of sawn timber, engineered wood products, and mass timber beams or slabs (e.g. cross laminated timber CLT, glued laminated timber GL, nail laminated timber), with or without concrete screeds, as well as for timber-concrete composite floors.
