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.

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
SIST EN 1740:2001 is a European standard that defines the testing procedures for assessing the mechanical performance of prefabricated reinforced components made from autoclaved aerated concrete (AAC) or lightweight aggregate concrete with open structure (LAC). These prefabricated components are primarily intended for use as vertical structural elements subjected to predominantly longitudinal loads, which may also involve transverse loads. The standard plays a vital role in ensuring structural reliability, safety, and durability in construction using AAC and LAC prefabricated components.
Key Topics
The standard outlines comprehensive methodologies to determine essential mechanical properties and behaviors, including:
Deflections under Serviceability Limit State
Evaluates how much a component will deform under normal service conditions, ensuring limits are not exceeded.Maximum Crack Width
Assesses visible cracking to maintain aesthetic and functional integrity during use.Loadbearing Capacity (Failure Load)
Measures the maximum load a component can support before structural failure. Essential for safety verification.Load-Deformation Diagram
Provides a graphical representation of load versus vertical deformation, useful for understanding material behavior (developed if required by the project specification).
Adherence to the standard enables manufacturers and structural engineers to demonstrate compliance with European performance requirements and provides a reliable basis for quality assurance.
Applications
SIST EN 1740:2001 is applicable to a variety of construction industry stakeholders, including:
Manufacturers of Prefabricated AAC and LAC Components
Use the standard's test methods to validate product performance before market entry.Structural Engineers and Designers
Reference mechanical performance data when specifying materials for vertical loadbearing walls, panels, or columns.Quality Assurance and Certification Bodies
Employ the standard during compliance checks and certification processes for prefabricated concrete elements.Building Project Managers and Contractors
Ensure chosen components meet the required mechanical standards, increasing project reliability and minimizing risk.
This standard is particularly relevant for projects involving multi-story buildings, high demand loadbearing structures, and applications where lightweight and thermally efficient materials are preferred for vertical elements.
Related Standards
Compliance and coordination with other standards ensures holistic quality and safety. Relevant related standards include:
- prEN 12602 - Product standard for autoclaved aerated concrete components.
- prEN 1520 - Product standard for lightweight aggregate concrete with open structure.
- EN 1992 (Eurocode 2) - Design rules for concrete structures.
- EN 206 - Specification and production of concrete.
Aligning with these documents helps achieve full conformity within the scope of European and international regulations for prefabricated concrete products.
In summary, SIST EN 1740:2001 serves as a key reference for ensuring that prefabricated AAC and LAC vertical components meet the stringent mechanical performance criteria required for safe and effective use in modern construction practices. Utilizing this standard supports quality, transparency, and competitiveness for manufacturers and builds solid confidence for designers and end-users.
