(Main)Design of tensioned membrane structures
Design of tensioned membrane structures
1.1 Scope of CEN/TS 19102
(1) This document applies to the design of buildings and structural works, made of structural membrane material. It provides guidance for the design of tensioned membrane structures, either mechanically or pneumatically tensioned at a defined prestress level.
NOTE 1 Membrane materials comprise structural fabrics, coated structural fabrics and foils.
NOTE 2 For elements of tensile surface structures not governed by this Technical Specification (for example made of steel, aluminium, wood or other structural materials), see relevant Eurocode parts.
(2) This document is concerned with the requirements for resistance, serviceability and durability of tensioned membrane structures, as given in EN 1990.
NOTE 1 The safety criteria follow EN 1990 and will consider specific limit states for tensioned membrane structures.
NOTE 2 Specific requirements concerning seismic design are not considered.
(3) Design and verification in this document is based on limit state design in conjunction with the partial factor method.
NOTE Special attention goes to the action of prestress, snow, wind and rain action on membrane structures and the combined effect of wind and rain or snow.
(4) This document covers analysis methodologies appropriate for tensioned membrane structures, from analytical to full numerical simulation methods.
(5) This document considers connections between membrane materials and between membrane materials and others.
(6) This document is applicable for hybrid membrane structures integrating different kinds of load bearing behaviour (tension, compression, bending, inflation…), in a way that the structural membrane shares loadbearing capacity with other structural elements made of different materials.
NOTE The term ‘hybrid structure’ refers to this combined structural behaviour or use of materials.
1.2 Assumptions
(1) The assumptions of EN 1990 apply to this document.
(2) This document is intended to be used in conjunction with EN 1990, the EN 1991 series, the EN 1993 series, the EN 1999 series, ENs, EADs and ETAs for construction products relevant to tensioned membrane structures.

ANMERKUNG 1 Membranwerkstoffe umfassen tragende Gewebe, beschichtete tragende Gewebe und Folien.
ANMERKUNG 2 Zu Bauelementen von Flächenzugtragwerken, die nicht Gegenstand dieses Dokuments sind (z. B. aus Stahl, Aluminium, Holz oder anderen Werkstoffen), siehe die maßgebenden Eurocode-Teile.
(2) Dieses Dokument behandelt die Anforderungen an Widerstand, Gebrauchstauglichkeit und Dauerhaftigkeit von vorgespannten Membrantragwerken, wie sie in EN 1990 angegeben sind.
ANMERKUNG 1 Die Sicherheitskriterien folgen EN 1990 und berücksichtigen spezifische Grenzzustände für vorgespannte Membrantragwerke.
ANMERKUNG 2 Besondere Anforderungen an die Bemessung gegen Erdbeben werden nicht berücksichtigt.
(3) Bemessung und Nachweis in diesem Dokument beruhen auf der Bemessung nach Grenzzuständen in Verbindung mit dem Verfahren mit Teilsicherheitsbeiwerten.
ANMERKUNG Besonderes Augenmerk gilt der Einwirkung von Vorspannung, Schnee, Wind und Regen auf Membrantragwerke sowie der kombinierten Auswirkung von Wind und Regen oder Schnee.
(4) Dieses Dokument behandelt für vorgespannte Membrantragwerke geeignete Berechnungsmethodologien von analytischen bis hin zu vollständig numerischen Simulationsverfahren.
(5) Dieses Dokument berücksichtigt Verbindungen von Membranwerkstoffen untereinander sowie mit anderen Werkstoffen.
(6) Dieses Dokument ist anwendbar für Hybridmembrantragwerke, die verschiedene Arten des Tragverhaltens (Zug, Druck, Biegung, Luftstützung usw.) so einschließen, dass sich die tragende Membran die Tragkraft mit anderen Tragwerkselementen aus unterschiedlichen Werkstoffen teilt.
ANMERKUNG Der Begriff „Hybridtragwerk“ bezieht sich auf diese(s) kombinierte Tragverhalten oder Verwendung von Werkstoffen.
1.2 Voraussetzungen
(1) Die Annahmen nach EN 1990 gelten für dieses Dokument.
(2) Dieses Dokument ist zur Anwendung in Zusammenhang mit EN 1990, der EN 1991-Reihe, der EN 1993 Reihe, der EN 1999-Reihe, EN, EAD und ETA für Bauprodukte, die für vorgespannte Membrantragwerke maßgebend sind, vorgesehen.

Projektiranje nateznih membranskih konstrukcij
(1) Ta dokument se uporablja za projektiranje stavb in konstrukcijskih objektov iz konstrukcijskega membranskega
materiala. Podaja smernice za projektiranje nateznih membranskih konstrukcij, ki so lahko mehansko ali
pnevmatsko napete na določeno raven prednapetosti.
OPOMBA 1: Membranski materiali so sestavljeni iz konstrukcijske tkanine, prevlečene konstrukcijske tkanine in folij.
OPOMBA 2: Za elemente nateznih površinskih konstrukcij, ki jih ne ureja ta tehnična specifikacija (npr. izdelanih iz jekla, aluminija, lesa ali drugih konstrukcijskih materialov), glej ustrezne dele Evrokoda.
(2) Ta dokument obravnava zahteve za odpornost, uporabnost in trajnost
nateznih membranskih konstrukcij, kot so podane v standardu EN 1990.
OPOMBA 1: Varnostna merila so skladna s standardom EN 1990 in bodo upoštevala posebna mejna stanja za natezne membranske konstrukcije.
OPOMBA 2: Posebne zahteve v zvezi s protipotresnim projektiranjem niso obravnavane.
(3) Projektiranje in potrjevanje v tem dokumentu temeljita na projektiranju po mejnih stanjih skupaj z metodo
delnih faktorjev.
OPOMBA: Posebna pozornost je namenjena vplivom prednapetostnih sil, snega, vetra in dežja na membranske konstrukcije in skupni vpliv vetra in dežja ali snega.
(4) Ta dokument zajema ustrezne metodologije za analizo nateznih membranskih konstrukcij, vse od analitičnih metod do metod povsem numeričnih simulacij.
(5) Ta dokument obravnava povezave med membranskimi materiali ter med membranskimi
in drugimi materiali.
(6) Ta dokument se uporablja za hibridne membranske konstrukcije z obnašanjem pri
obremenitvi (napetost, stiskanja, upogibanje, napihovanje itd.) na način, da konstrukcijska membrana
skupaj z drugimi konstrukcijskimi elementi, izdelanimi iz različnih materialov, prav tako zagotavlja nosilnost.
OPOMBA: Izraz »hibridna konstrukcija« se nanaša na to kombinirano konstrukcijsko obnašanje ali uporabo materialov.
