(1) This document provides general design rules for fibre-polymer composite structures for buildings, bridges and civil engineering structures, including permanent and temporary structures.
NOTE Fibre-polymer composites are commonly referred to as fibre-reinforced polymers (FRP) or as composites. In EN 19101-1-1, fibre-polymer composite materials are referred to as “composite materials” or as “composites”.
(2) This document contains minimum provisions related to execution upon which the design provisions in EN 19101-1-1 rely.
(3) This document gives the general basis for the design of composite structures composed of (i) composite members or (ii) combinations of composite members and members of other materials (hybrid-composite structures), and (iii) the joints between these members.
NOTE Structures can also consist of single integrated members, e.g. in the case of slab bridges.
(4) This document applies to composite structures in which the values of material temperature in members, joints and components in service conditions are (i) higher than -40 °C and (ii) lower than - 20 °C, where is the glass transition temperature of composite, core and adhesive materials, defined according to 5.1(1).
NOTE 1 Composite structures have a temperature-dependent behaviour. The temperature-dependence of the properties of composite, core and adhesive materials is considered through a conversion factor for temperature, nc, as defined in 4.4.7.2, which depends on the Tg and the maximum material temperature in service conditions (Ts).
NOTE 2 5.1(1) defines requirements for the Tg of composite, core and adhesive materials as a function of the Ts.
NOTE 3 Material temperatures above Tg - 20 °C are considered elevated temperatures.
(5) This document applies to composite members, i.e. profiles and sandwich panels, and to composite built-up members.
NOTE 1 Profiles and sandwich panels can be applied in structural systems composed of beams, columns, bars, frames, trusses, slabs, plates and shells.
NOTE 2 Sandwich panels include homogeneous core and web-core panels. In web-core panels, the cells between webs can be filled (e.g. with foam) or remain empty (e.g. panels from pultruded profiles).
NOTE 3 Built-up members can result from the assembly of two or more profiles, through bolting and/or adhesive bonding.
(6) This document applies to composite members produced by the main manufacturing processes, which include pultrusion, filament winding, hand layup, resin transfer moulding (RTM), resin infusion moulding (RIM) and vacuum-assisted resin transfer moulding (VARTM).
(7) This document does not cover sandwich panels made of metallic face sheets.
(8) This document does not apply to composite cables or special types of civil engineering works (e.g. pressure vessels, tanks or chemical storage containers).
(9) This document applies to bolted, bonded and hybrid joints and their connections.
(10) This document applies to the following components:
(i) the composite components of composite members, i.e. composite plies, composite laminates, sandwich cores and plates or profiles, and (ii) the components of joints or their connections, i.e. connection plates or profiles (e.g. cleats), bolts, and adhesive layers.
NOTE 1 Composite components are composed of composite materials (i.e. fibres and matrix resins) and core materials. Components of joints and their connections are also composed of composite, steel or adhesive materials.
NOTE 2 The fibre architecture of composite components can comprise a single type of fibres or a hybrid of two or more types of fibres.
NOTE 3 This document does not apply to composite components used for internal reinforcement of concrete structures (composite rebars) or strengthening of existing structures (composite rebars, strips or sheets).
