Timber structures - Test methods - Load bearing stapled joints
This European Standard specifies test methods for determining the strength and deformation characteristics of stapled joints in load-bearing timber structures.
The methods assess joints with members of timber (solid timber and glued laminated timber) or wood-based products in the combination proposed for use in service and using all types of staples up to 3 mm diameter for circular cross-section staples or 4 mm x 2 mm for rectangular or oval cross-section staples.
The methods determine load-slip characteristics and maximum load of joints with laterally loaded staples where various angles between the applied force and the timber grain direction or the main direction of the wood-based products, respectively, are possible.
Holzbauwerke - Prüfverfahren - Tragende Klammerverbindungen
Diese Europäische Norm legt Prüfverfahren zur Bestimmung der Festigkeits- und Verformungseigenschaften von Klammerverbindungen in tragenden Holzbauwerken fest.
Diese Verfahren prüfen Verbindungen mit Holzteilen (Vollholz und Brettschichtholz) oder Holzwerkstoffen in der für die Anwendung vorgesehenen Kombination unter Verwendung aller Typen von Klammern mit kreisförmigem Querschnitt bis zu 3 mm Durchmesser oder mit rechteckigem oder ovalem Querschnitt mit bis zu 4 mm × 2 mm.
Die Verfahren bestimmen das Last-Verschiebungs-Verhalten und die Höchstlast von Verbindungen mit rechtwinklig zum Klammerschaft beanspruchten Klammern, wobei verschiedene Winkel zwischen der einwirkenden Last und der Faserrichtung des Holzes oder der entsprechenden Hauptrichtung von Holzwerkstoffen möglich sind.
Structures en bois - Méthodes d'essai - Assemblages agrafés porteurs
La présente norme européenne définit les méthodes d'essais permettant de déterminer la résistance et la déformabilité d'assemblages agrafés dans des structures porteuses en bois.
Les méthodes supposent des assemblages de membrures en bois (bois massif ou bois lamellé collé) ou en matériaux à base de bois dans des combinaisons proposées en service et utilisant tous types d'agrafes d'un diamètre maximal de 3 mm pour les agrafes de section circulaire et de 4 mm x 2 mm pour celles de section rectangulaire ou ovale.
Les méthodes permettent de déterminer les caractéristiques force/glissement ainsi que la charge maximale pouvant être supportée par des assemblages réalisés avec des agrafes chargées latéralement avec un angle quelconque entre la force appliquée et l'orientation des fibres ou de la direction principale du matériau à base de bois.
Lesene konstrukcije - Metode preskušanja - Nosilni spoji s sponkami
Ta standard določa preskusne metode za ugotavljanje trdnostnih in deformacijskih lastnosti spojev s sponkami pri nosilnih lesenih konstrukcijah.
Metode obravnavajo spoje z lesnimi členi (iz masivnega in lepljenega lameliranega lesa) ali lesnimi proizvodi v kombinaciji, priporočeni za uporabo v praksi, pri čemer se uporabljajo vse vrste sponk s premerom največ 3 mm za sponke s krožnim prečnim prerezom ali 4 x 2 mm za sponke s pravokotnim ali ovalnim prečnim prerezom.
Na podlagi metod je mogoče določiti obremenitvene/drsne lastnosti in največjo obremenitev spojev z vodoravno vstavljenimi sponkami, pri čemer je možnih več kotov med uporabljeno silo in usmerjenostjo lesnih vlaken ali glavno usmerjenostjo lesnih proizvodov.

Overview
EN 1381:2016 - published by CEN - is the European Standard that specifies laboratory test methods for load‑bearing stapled joints in timber structures. It defines how to determine the strength and deformation (load‑slip) characteristics of stapled connections made with timber (solid and glued laminated) and wood‑based products, using staples up to 3 mm diameter (round) or 4 mm × 2 mm (rectangular/oval). The methods cover laterally loaded staples and allow testing at various angles between the applied load and the timber grain or main direction of wood‑based materials.
Key topics and requirements
- Scope of testing
- Joints made from timber or wood‑based products in the combination intended for service.
- Staples with circular, rectangular or oval cross‑sections up to the sizes stated above.
- Measurement of load‑slip characteristics and maximum load for laterally loaded staples.
- Test piece geometry
- Typical test pieces are three‑member joints with four staples per side, loaded in single shear (figures and dimensions specified).
- Tests for loads parallel and perpendicular to grain; special consideration of staple crown angle (crn = 30° or 60° where applicable).
- Material selection & conditioning
- Timber and wood‑based materials selected per referenced density/moisture procedures; density variation limits apply.
- Conditioning regimes specified (e.g., (20 ± 2) °C and (65 ± 5) % RH, or (85 ± 5) % RH for smooth leg staples) until constant mass is achieved.
- Test procedure & reporting
- Tests follow principles of EN 26891 with additions for stapled joints (restraining instability, ensuring free separation/pull‑out).
- Detailed test report requirements (material properties, staple details, dimensions, insertion method, moisture content, load procedure, individual results, failure modes).
Applications and users
EN 1381:2016 is used to:
- Validate and qualify stapled connections for load‑bearing timber construction (roof trusses, shear connections, panel fixings).
- Provide laboratory data for structural design, performance verification and mechanical fastener selection. Primary users include:
- Structural and connection design engineers
- Testing laboratories and certification bodies
- Timber product and fastener manufacturers
- Construction quality control, researchers and standards committees
