5 Standards, guidelines and other documents referred to in this European technical approval are listed in Annex 15. electronic copy electro OIB-250-005/06-249 Page 7 of European technical approval ETA-13/0840 Validity from 28.06.2013 to 27.06.2018
Structural members that meet the following requirements according to EN 1992-1-1 for bending and tensile loads: The steel’s characteristic yield strength to transfer tension loads is limited to fyk ≤ 600 N/mm² in the ultimate limit state; The required verifications are carried out for the serviceability limit state; For exceptional load cases, limitation of the yield strength is not required. Bases for design, detailing and execution are specified in EN 1992 and EN 13670. In addition, copy electronic the following items shall be observed: In order to fully exploit the steel’s compressive yield strength, the creep and shrinkage redistributions may be taken into account; The thread bars’ stress-strain curves are identical both under tension and compression; Moment redistributions are permissible only if exact verifications are carried out; For additional considerations on design and detailing see section 4.2. The provisions specified in the European technical approval are based on an assumed working life of 100 years6 for the SAS 670 high-strength reinforcing system. The indications given as to the working life of the kit cannot be interpreted as a guarantee given by the kit manufacturer or the Approval Body issuing the ETA, but are regarded only as a means for selecting the appropriate products in relation to the expected economically reasonable working life of the works.
2 Characteristics of the product and methods of verification 2.1 General The components of the reinforced concrete members subjected to predominantly compressive loading as well as the assembled system are shown in the drawings in the annexes of the European technical approval. The material parameters, dimensions and tolerances of nic copy electronic components not specified in the annexes shall comply with the data listed in the technical documentation7 of the European technical approval.
2.2 Steel load-bearing element The load-bearing element is a hot-rolled and in line heat treated steel bar S 670/800, nominal Ø 18 to 63.5 mm, with right-hand thread ribs. The steel is referred to as SAS 670. The steel bar is developed for geotechnical and reinforcement applications. Up to Ø 43 mm, the bars are weldable. The larger diameters of 50, 57.5 and 63.5 mm are suitable for welding. However, welding shall be performed according to defined procedures in accordance with EN ISO 17660. Up to Ø 43 mm the bars are bendable. Larger Ø are not intended to be bent, but bending may be verified for individual projects.
6 Assumed working life means that when this working life has elapsed the real working life may be, in normal use conditions, considerably longer without major degradation affecting the essential requirements. The real working life of a product incorporated in a specific works depends on the environmental conditions to which that works is subject and the particular conditions of the design, execution, use and maintenance of that works. Therefore, it cannot be excluded that in these cases the real working life of the product may also be shorter than the assumed working life. 7 The technical documentation of the European technical approval is deposited at Österreichisches Institut für Bautechnik and, in so far as is relevant to the tasks of the approved body involved in the attestation of conformity procedure, is handed over to the approved body. electronic copy electro OIB-250-005/06-249 Page 8 of European technical approval ETA-13/0840 Validity from 28.06.2013 to 27.06.2018

The planned position of the reinforcing bars shall take the required concrete cover and clear distance into account. 4.2.3 Design The design shall be carried out based on EN 1992-1-1 and EN 1992-1-2. The following notes shall be observed: The compressive strain limits of concrete for serviceability limit state according to EN 1992-1-1 shall be verified. copy electronic For the transfer of tension loads, the maximum characteristic steel stress shall be limited in accordance with the national standards (according to EN 1992-1-1: fyk = 600 N/mm²). If the structural members are subjected to bending and tensile loads, the limitation of the crack widths shall be verified. If required, a skin reinforcement shall be installed for crack distribution. Deviating from the standard, the following notes may be taken into consideration: In order to exploit the steel, creep and shrinkage redistributions may be taken into account. The creep and shrinkage assumptions specified in EN 1992-1-1 shall be used. The respective loading history shall be taken into account. It suffices to discretise the load using 5 to 10 load steps. For the actions, the increased deformations resulting from redistribution shall also be taken into consideration. For buckling verification, the increased deformations must be taken into account. Characteristic and design bond stress values, dependent on the concrete grade, are listed in Table 3. Stress range in fatigue tests are given in Table 5. Bond stresses induced by the load transfer and creep redistribution shall be verified.

4.2.4 Detailing If not stated otherwise, the detailing provisions of EN 1992-1-1 apply: The reinforcement percentage shall not exceed 20 %. Contact splices may be designed as 100 %-efficient splices. However, for practical purposes, they should be designed as 50 %-efficient splices and staggered as specified in Annex 12. Torqued coupler splices may be designed as 100 %-efficient splices. For planned tensile loading, they should be designed as 50 %-efficient splices and staggered as specified in Annex 12. The minimum diameter and the maximum centre spacing of the stirrup reinforcement may be taken according to Table 4. The centre and edge distances of the anchorages are listed in Annex 10 and 11. electronic copy electro OIB-250-005/06-249 Page 15 of European technical approval ETA-13/0840 Validity from 28.06.2013 to 27.06.2018

4.2.5 Fire safety For fire safety, special measures shall be taken. The fire resistance classes shall be specified for the respective structural members, dependent on the building height and category. In order to attain the fire resistance class, the required minimum dimensions and minimum concrete cover shall be installed. The minimum dimensions are specified in EN 1992-1-2, section 5. 4.2.6 Corrosion protection nic copy electronic The corrosion protection of the high strength reinforcing system shall be ensured by an appropriate concrete cover.
5 Recommendations for the manufacturer 5.1 Packaging, transport and storage of the product The approval holder shall have written instructions related to: Temporary protection of the reinforcing bars and accessories in order to prevent corrosion during transport from the production plant to the construction site; Transportation, storage and handling of the reinforcing bars and accessories in order to avoid any mechanical, chemical or electrochemical changes; Protection of the reinforcing bars and accessories from moisture when stored outdoors. For storage and installation of the SAS 670 system for high-strength reinforced structural members, the instructions of the approval holder shall be observed.
5.2 Use, maintenance and repair The assessment of the fitness for use is based on the assumption that maintenance is not required during the assumed intended working life. electronic copy electro OIB-250-005/06-249 Page 16 of European technical approval ETA-13/0840 Validity from 28.06.2013 to 27.06.2018
5.3 Accompanying information It is the responsibility of the approval holder to ensure that all necessary information on design, detailing and installation is given to those responsible for the design, detailing and execution of structures in which SAS 670 high-strength reinforcing systems are installed.
