THE TECNARIA SYSTEM: tested and certified according to Eurocode 5
Eurocode 5
(UNI ENV 1995) is a
standard that defines the
regulations pertaining to the design, calculation and execution of timber structures. It is
shared by the countries belonging to the European Community and represents an alternative to
the various national regulations. It is used in connection with other European standards that
establish material characteristics and testing
methods.
TECNARIA was the first company in Europe to subject its connectors to accurate experimental analysis according to the standards quoted by
Eurocode 5.
Stiffness and strength characteristics of the connector fastened to timber have been experimentally verified at:
- CNR of Florence - Istituto per la Ricerca sul Legno (Wood Research Institute):
"Evaluation of the behaviour of Tecnaria connectors in compliance with Eurocode 5
standards" [January 2001].
- Experimental Laboratory for Building Material Testing of the Faculty of Engineering - Institute of Tectonics - University of Padua:
"Evaluation of the behaviour of Tecnaria connectors in compliance with Eurocode 5
standards" [March 1995, September 1995, June 1996].
The above tests were
conducted in compliance with the following standards:
UNI ENV 1995
Eurocode 5.
Design of timber structures.
UNI EN 26891 Timber structures. Joints made with mechanical fasteners.
General principles for the determination of strength and deformation
characteristics.
UNI EN 28970 Timber structures. Testing of joints made with mechanical
fasteners. Requirements for wood density.
UNI EN 338 Structural timber. Strength classes.
UNI EN 380/00 Timber structures. Test methods. General principles for static
load tests.
The Tecnaria connectors have also been tested at:
University of Trieste - Department of Civil Engineering: "Evaluation of the
short- and long-term behaviour of timber-concrete mechanical connections".
A study of the long-term behaviour of the Tecnaria connection system in composite
timber-concrete structures in conditions of constant humidity and temperature (creep
or viscosity tests) and in conditions of variable humidity, under the action of a
service load with plain and light-weight concrete. Test term: 9 months [September
2000].
The connectors have also been subjected to experimental testing at: Universität
Leipzig, Institut für Massivbau und Baustofftechnologie (University of Leipzig -
German Federal Republic) "Push-out tests with Tecnaria stud connectors in
timber-Light weight aggregate concrete composite structures" (November 1999).
Universidade do Minho - Departamento de Engenharia Civil Portugal "Programa de ensaios em vigas mistras madeira-betão".
The dowel and crampons connector is a product covered by European patent.
