ISO 19049:2016 defines the test method for horizontal diaphragms including floors and horizontal and sloped roofs under static loads. This test method is designated to evaluate the static shear capacity of a typical segment of a diaphragm under applied static loads, and to evaluate the stiffness of the diaphragm assembly.

Abstract

Overview

ISO 19049:2016 - Timber structures - Test method - Static load tests for horizontal diaphragms including floors and roofs - defines a standardized laboratory procedure to measure the static shear capacity and apparent shear stiffness of horizontal diaphragms (floors and horizontal/sloped roofs) made with timber, panels, sheathings and fasteners. The method evaluates a representative diaphragm segment under static bending loads (simple span or cantilever) to replicate in-plane shear action produced by wind or seismic forces.

Key Topics and Requirements

Scope: Static load testing of horizontal diaphragms (floors and roofs) to determine shear strength and stiffness for use in structural interpretation and design.
Test configurations: Cantilever and simple-span assemblies with concentrated or distributed loading; specimens may be tested horizontally, vertically or at slope for roofs.
Specimen construction: Materials, dimensions, joints and fastenings shall be representative of intended field use; specimens must be large enough (minimum dimensions and elements specified) to reflect real behavior.
Conditioning: Specimens conditioned at (20 ± 2) °C and (65 ± 5) % RH in accordance with ISO 554; wood density determined per ISO 13061-2.
Apparatus & calibration: Test frames must be calibrated. If frame stiffness exceeds 2% of total assembly stiffness, test results are adjusted for frame resistance.
Measurements & accuracy:
- Load and displacement recording accuracy: ±1% (or better) for P and Δ.
- Load measuring devices: ±2% accuracy.
- Deformation gauges: ±1% for typical ranges, or ±0.1 mm for displacements
