标准范围

本文件中提供的设计方法解决了居住者行走动作引起的振动，并涵盖了以下木地板系统:A）？木托梁间距不超过610？mm，带有一层结构木质底层地板，使用机械紧固件或粘合剂连接到托梁。没有找平层（顶层）和天花板的裸露轻型框架地板的面积密度不大于25？千克/平方米。身材？图1示出了这种轻型框架地板。b）？用大体积木板建造的大体积木地板，如交叉层压木材（CLT）。本文件由三部分组成:A）？使用基本固有频率和1？以kN静点荷载挠度为设计参数，包括耦合准则和解耦准则两种设计准则；b）？用于计算设计参数的方程；c）？地板构件物理和机械性能设计值指南。设计方法是基于楼板系统具有单跨和简支条件的假设。

The design method provided in this document addresses vibration induced by walking action of occupants and covers the following timber floor systems:

a)       Light frame floors built with timber joists spaced at a distance of no more than 610 mm with a layer of structural wood-based subfloor that is connected to the joists using mechanical fasteners or adhesive. The area density of a bare light frame floors without a screed (topping) and ceiling is not greater than 25 kg/m². Figure 1 shows such a light frame floor.

b)       Mass timber floors built with mass timber panels such as cross laminated timber (CLT).

This document consists of three elements:

a)       a baseline vibrational serviceability design criterion for timber floors using fundamental natural frequency and 1 kN static point load deflection as the design parameters including two types of design criteria, coupled and decoupled criteria;

b)       equations for calculating the design parameters;

c)        guidelines for the design values of the physical and mechanical properties of floor components.

The design method is based on the assumption that the floor system has a single span and simple support conditions.
