(Main)Performance test for prefabricated reinforced components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure under predominantly longitudinal load (vertical components)
Performance test for prefabricated reinforced components made of autoclaved aerated concrete or lightweight aggregate concrete with open structure under predominantly longitudinal load (vertical components)
This European Standard specifies a method of determining the mechanical performances of prefabricated components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to prEN 1520 under longitudinal load which may be combined with transverse load. These performances include: - the deflections and maximum crack width in the serviceability limit state; - the loadbearing capacity (failure load); - the load-(vertical) deformation diagram, if required.
Bestimmung des Tragverhaltens von vorgefertigten bewehrten Bauteilen aus dampfgehärtetem Porenbeton oder aus haufwerksporigem Leichtbeton unter vorwiegend in Längsrichtung wirkender Belastung (vertikale Bauteile)
Diese Europäische Norm legt ein Verfahren fest zur Bestimmung des mechanischen Verhaltens von vorgefertigten Bauteilen aus dampfgehärtetem Porenbeton (AAC) nach prEN 12602 oder haufwerksporigem Leichtbeton (LAC) nach prEN 1520 unter in Längsrichtung wirkender Belastung, die mit einer quer zur Bauteilebene wirkenden Belastung kombiniert werden darf. Hierzu gehören: - die Durchbiegungen und die größte Rißbreite im Grenzzustand der Gebrauchstauglichkeit; - die Tragfähigkeit (Bruchlast); - das Last-(vertikale) Verformungs-Diagramm, falls gefordert.
Détermination de la résistance des éléments préfabriqués réalisés en béton cellulaire autoclavé ou en béton de granulats légers a structure ouverte sous charge longitudinale prédominante (composants verticaux)
La présente norme européenne définit une méthode de détermination des performances mécaniques des éléments préfabriqués réalisés en béton cellulaire autoclavé (AAC) conformes au prEN 12602 ou en béton de granulats légers à structure ouverte (LAC) conformes au prEN 1520 sous charge longitudinale, éventuellement en combinaison avec une charge transversale. Ces performances concernent: - les déformations et l'épaisseur maximale des fissures à l'état limite d'utilisation; - la résistance à la compression (charge de rupture); - le diagramme charg-déformation (verticale), si nécessaire.

Overview
EN 1740:1998 (CEN) defines a standardized method to determine the mechanical performance of prefabricated reinforced components made of autoclaved aerated concrete (AAC) or lightweight aggregate concrete with open structure (LAC) when subjected to predominantly longitudinal loads. The standard covers vertical components and allows for longitudinal loads to be combined with transverse actions. Key measured outcomes include serviceability behavior and ultimate loadbearing capacity.
Why this standard matters: it provides a reproducible test procedure to quantify deflections, crack width at the serviceability limit state, and the failure load - enabling manufacturers, test laboratories and specifiers to compare performance and demonstrate compliance.
Key Topics
- Scope and materials: Applies to prefabricated reinforced components made of AAC (per prEN 12602) or LAC (per prEN 1520).
- Performance measures:
- Deflections in service and under design loading
- Maximum crack width at the serviceability limit state
- Loadbearing capacity (failure load)
- Load–(vertical) deformation diagram, where required
- Load conditions: Predominantly longitudinal loadings on vertical elements; combination with transverse loads is permitted within the method.
- Repeatability: Procedure aims to ensure consistent, comparable results across test campaigns and laboratories.
Applications
EN 1740:1998 is directly relevant for:
- Manufacturers of prefabricated AAC and LAC reinforced vertical components seeking verified performance data for product documentation and CE marking processes.
- Testing laboratories performing structural performance trials on wall panels, columns, or other vertical prefabricated elements made from AAC or LAC.
- Structural engineers and specifiers who need verified data on deflection limits, crack control and ultimate capacity to inform design decisions.
Benefits and practical value:
- Improved quality control: Standardized performance testing supports consistent production and verification.
- Risk reduction: Measured failure loads and deformation behaviour help assess safety margins and serviceability.
- Design integration: Test results feed directly into structural assessments and compliance documentation.
