EUROCODE 5

Objective

- TO IDENTIFY DIFFERENCES BETWEEN GRADING SYSTEMS OF THE DIFFERENT COUNTRIES AND SYSTEMS IN THE COMMUNITY.

- TO ESTABLISH STANDARDISED PROCEDURES FOR SAMPLING, TESTING, COLLATING, ANALYSIS ON EUROPEAN TIMBERS IN ORDER TO OBTAIN CHARACTERISTIC VALUES.

WITH THE INTRODUCTION OF THE TIMBER DESIGN CODE EC 5, WHICH WILL HAVE AUTHORITY THROUGHOUT THE EUROPEAN COMMUNITY, IT IS IMPORTANT THAT INTERNATIONAL AGREEMENT CAN BE REACHED ON A STANDARDISED METHOD FOR DETERMINING CHARACTERISTIC STRENGHT VALUE FOR STRESS GRADED TIMBER.

DIFFERENT COUNTRIES HAVE DEVELOPED THEIR OWN GRADINF SYSTEM WHICH SUIT THEIR SPECIES, MARKET CONDITIONS AND STRUCTURAL DEMANDS, AND IT IS UNLIKELY THAT ONE GRADING SYSTEM WOULD FIND FAVOUR WITH ALL OF THEM.

THE AIM SHOUL THEREFORE BE TO ASSIGN THE VARIOUS GRADING SYSTEMS TO THE ATRENGHT CLASSES, AND FOR THIS A STANDARDISED METHOD FOR DERIVING CHARACTERISTIC VALUES IS ESSENTIAL.

- THE RESEARCH IS DIVIDED IN:
- COMPARISON ABOUT NATIONAL AND EEC GRADING RULES BY TESTING 500 SAMPLES OF BOTH " STITKA SPRUCE " AND "NORWAY SPRUCE" .
- COLLECT DETAILED INFORMATION ON NATIONAL RULES FOR DERIVATION OF CHARACTERISTIC VALUES AND ESTABLISH STANDARD PROCEDURES.
