Timber structures - Test methods - General principles for static load testing

This standard specifies the general principles to be adopted for static load testing of timber structures or components. It is intended for use where it is necessary to verify by test that a structure or components complies with stated criteria. Relevant parts may be used for proof loading or for the testing of structures in service. This standard is not intended to be used for testing of individual pieces of timber, individual joints or structural scaled models

Holzbauwerke - Prüfverfahren - Allgemeine Grundsätze für die Prüfung unter statischen Belastungen

Diese Norm legt allgemeine Grundsätze fest, die für die Prüfung von Holzkonstruktionen oder -bauteilen unter statischer Belastung anzuwenden sind. Sie ist dort für die Anwendung vorgesehen, wo es erforderlich ist, durch Prüfungen nachzuweisen, dass eine Konstruktion oder ein Bauteil die festgelegten Kriterien erfüllt. Zutreffende Teile dürfen für Probebelastungen oder für die Prüfung von Konstruktionen im Gebrauchßustand angewandt werden.

Structures en bois - Méthodes d'essais - Principes généraux d'essais par chargement statique

La présente norme spécifie les principes généraux des essais sous charge statique des structures et éléments de structures en bois. Elle s'applique aux cas où il est nécessaire d'effectuer des essais pour vérifier si une structure est conforme à des critères déclarés. Certaines parties de la norme peuvent convenir aux épreuves, ou aux essais de structures en place. La présente norme n'est pas destinée à la réalisation d'essais sur les pièces de bois isolées, des assemblages isolés ou des maquettes de structures

Overview

EN 380:1993, titled Timber Structures - Test Methods - General Principles for Static Load Testing, is a European standard developed by CEN that outlines the fundamental principles to be followed when performing static load tests on timber structures or components. This standard is essential for verifying that timber constructions meet predefined performance criteria under static loading conditions. It serves as a guideline for proof loading, as well as testing structures that are already in service to ensure safety and compliance.

Key Topics

• Scope of Application
  EN 380:1993 focuses on static load testing at the structural or component level, and it excludes testing of individual timber pieces, individual joints, or structural scale models.

• Static Load Testing Principles
  The document provides standardized procedures to conduct static load tests that help determine the load-bearing capacity and deformation characteristics of timber constructions.

• Verification of Structural Performance
  It is intended to confirm that timber structures can withstand the loads they are subjected to by simulating realistic static load scenarios.

• Test Execution Guidelines
  The standard details methods for applying loads, monitoring displacements, and assessing results to maintain consistency and reliability in load testing.

Applications

• Construction Quality Assurance
  EN 380:1993 is used during the quality control phase in timber construction to verify that structures meet design and safety requirements through static load testing.

• In-service Structure Testing
  It facilitates testing of existing timber structures to assess current performance levels, helping in maintenance decisions and safety evaluations.

• Proof Loading of Timber Components
  Enables proof loading to ensure components and assemblies perform as expected before or after installation.

• Compliance Verification
  Helps engineers and construction professionals demonstrate compliance with building regulations and contractual specifications regarding load capacity.

Related Standards

• EN 1995 (Eurocode 5)
  Design of timber structures, complementing the verification by test methods as defined in EN 380.

• EN 408
  Structural timber - Strength classes and determination of physical and mechanical properties – provides classification criteria relevant for tests.

• EN 26891
  Timber structures - Joints made with mechanical fasteners - General principles for the determination of strength and deformation properties, focusing on joints rather than whole structures.

• ISO 6892
  Testing metallic materials under static load conditions; although focused on metals, it shares fundamental principles applicable to testing methodologies.

Practical Value

Following EN 380:1993 ensures reliable and repeatable static load testing results, which are critical for the safety, durability, and performance certification of timber structures. Whether for new constructions or in-service assessments, it helps structural engineers and construction professionals apply consistent test methods that support regulatory compliance and quality assurance in timber engineering projects.
