Integrated study of the long-term performance of wood-based panels in floor and roof construction

Objectives

The project is concerned with a number of inter-relationships among components in an integrated chain linking raw materials with component performance. The links in that chain embrace raw materials, board manufacture, board characterisation, duration of load and moisture resistance of the boards, component performance, and structural design for long-term performance, reliability and economy.

Technical Approach

The project comprises 7 main tasks which together aim to increase the efficiency in use of wood-based panels without compromising structural integrity and safety.

Expected Results

Selection of boards and preparation of test pieces
Development of a method of assessment for the performance of tongue and groove joining profiles
The effect of sample size on creep
Sampling and matching
Non-destructive methods of characterising creep test pieces
Demonstration by creep testing
Alternative binders
Isocyanate bonded boards
Cement bonded particleboard
Long-term concentrated load performance
Component tests
Small scale test method
Bending creep
Integration of test methodology, Eurocode 5 and a performance-based design approach

Progress to Date

Test materials acquired, cut and distributed
Test rigs manufactured
Test programme 50% completed
Analysis of test results started
