Floor structures: Deflection of light-weight structures subjected to a concentrated load (NT BUILD 341)

Abstract

1. SCOPE

This NORDTEST method describes how to measure the maximum deflection of floor joists when the floor is loaded with a 1.0 kN static, concentrated load. The deflection is used as a design criterion for determining maximum floor spans, taking into account the composite action between floor sheathing and joists.

2. FIELD OF APPLICATION

The method is applicable for laboratory prototype testing of lightweight floors with wood or steel joists.
