91.080.40 - Concrete structures

This document specifies requirements for steel strand which has been given a stress-relieving heat treatment according to the general requirements specified in ISO 6934-1. This document covers 10 grades of steel strand for use in prestressed concrete construction; each strand can contain either 2, 3, 7 or 19 individual wires. In case of any conflict between the requirements of this document and ISO 6934-1, the requirements of document prevail.

This Technical Report explains the reasoning behind the requirements and procedures given in EN 13791 [1] and why some concepts and procedures given in EN 13791:2007 [2] were not adopted in the 2017 revision. The annex comprises worked examples of the procedures given in EN 13791.

The present document refers to the panel-to-structure and panel-to panel connections used for the cladding systems of reinforced concrete frame structures of single-storey buildings, typically precast. They can be used also for multi-storey buildings with proper modifications. The fastening devices considered in the present document consist mainly of steel elements or sliding connectors. Dissipative devices with friction or plastic behaviour are also considered. Other types of common supports an...view more

This document provides a guideline for the selection of a proper grout material to repair water leakage through cracks and other deformities in concrete structures. The factors relevant to the quality control of maintenance and repair of water-leakage cracks are as the following; a) conditions of water-leakage cracks; b) performance requirements for repair materials; c) different types of repair materials (grouts); d) procedures followed to select the appropriate repair materials; e) execution o...view more

This document provides general principles for the verification and assessment of the performance of concrete structures with the applications of different fibre-reinforced polymer (FRP) systems varying from internal FRP reinforcements/tendons, external FRP tendons, externally bonded FRP sheets/plates, to near-surface mounted FRP reinforcement. It can be used for the international harmonization of the design of un-reinforced, conventionally reinforced, and pre-stressed concrete structures with th...view more

This document specifies requirements and provides recommendations applicable to fixed, floating and grounded concrete offshore structures for the petroleum and natural gas industries and for structures supporting nationally-important power generation, transmission or distribution facility. This document specifically addresses - the design, construction, transportation and installation of new structures, including requirements for in-service inspection and possible removal of structures, - the as...view more

This document refers to connections in precast frame systems, either for single-storey or multi-storey buildings. The connections for all orders of joints are considered. Large wall panel and three-dimensional cell systems are not considered. According to the position in the overall construction and of the consequent different structural functions, the seven following orders of joints are considered: a) mutual joints between floor or roof elements (floor-to-floor) that, in the seismic behaviour ...view more

This document specifies technical requirements for ribbed bars to be used as reinforcement in concrete. It is applicable to steel delivered in the form of bars, coils and de-coiled products. This document covers both weldable and non-weldable steels. It does not apply to ribbed bars produced from finished products, such as plates and railway rails. The production process is at the discretion of the manufacturer.

(1)   This European Standard:
-   gives methods and procedures for the estimation of the in-situ compressive strength and characteristic in-situ compressive strength of concrete in structures and precast concrete components using direct methods (core testing) and indirect methods, e.g. ultra-sonic pulse velocity, rebound number;
-   provides principles and guidance for establishing the relationships between test results from indirect test methods and the in-situ compressive strength;
-   provides pro...view more

This document provides the principles and procedures of environmental management for maintenance/remedial activities of concrete structures, and environmental management during the operation of concrete structures. When the environmental design of a concrete structure is to be carried out based on ISO 13315‑4, this document provides detailed information on the design for its use stage.

This document applies to reinforced concrete building consisting of load bearing walls of reinforced concrete buildings [such buildings are called reinforced concrete box-shaped wall buildings and (RC wall building)] or to the part of RC wall building which uses both this and other types of structure. This document applies to RC wall building as follows: — RC wall building with 5 or fewer aboveground storeys; — eaves height of 16 m or less; — storey height on each storey of 3 m or less; — on the...view more

1.1   General
This Technical Report provides design rules for fasteners used to connect statically indeterminate non-structural light weight systems (e.g. suspended ceilings, pipe work, ducting) to concrete members such as walls or floors (see Figure 1)).
The proposed design model may be applied to post-installed mechanical and bonded anchors covered by EN 1992-4:2017, 1.2. Their suitability will be confirmed in a European Technical Product Specification.
The design rules assume the following:

EN 1992-4 covers anchor channels located in cracked or uncracked concrete subjected to tensile loads and/or shear loads transverse to the longitudinal channel axis as well as combinations of these loads. Shear loads acting in direction of the longitudinal axis of the channel and combinations of shear loads acting transverse and in direction of the longitudinal axis of the channel, combinations of tensile loads and shear loads acting in direction of the longitudinal axis of the channel and combin...view more
