This document specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections of circular, square, rectangular or elliptical forms. It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product. NOTE 1 The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2. NOTE 2 The provisions that apply under the Construction Products Regulations (CPR) are specified in EN 10380. NOTE 3 The attention of users is drawn to the fact that whilst cold formed grades in EN 10219-1 can have equivalent mechanical properties to hot-finished grades in this document the sectional properties of square and rectangular hollow sections in EN 10210-2 and EN 10219-2 are not equivalent. NOTE 4 A range of material grades is specified in this standard and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are generally comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5 and EN 10025-6. NOTE 5 The requirements for seamless and welded steel structural hollow sections for use in offshore structures are covered in EN 10225. NOTE 6 Spiral welded hollow sections must be used with caution in applications involving dynamic behaviour (fatigue stress) as, up to now, there is insufficient data regarding their performance.

 

1.1 Scope of EN 1999-1-5 (1) EN 1999-1-5 applies to the structural design of aluminium structures, stiffened and unstiffened, that have the form of a shell of revolution or of a round panel in monocoque structures. (2) EN 1999-1-5 covers additional provisions to those given in the relevant parts of EN 1999 for design of aluminium structures. NOTE Supplementary information for certain types of shells is given in EN 1993-1-6 and the relevant application parts of EN 1993 which include: - Part 3-1 for towers and masts; - Part 3-2 for chimneys; - Part 4-1 for silos; - Part 4-2 for tanks; - Part 4-3 for pipelines. (4) The provisions in EN 1999-1-5 apply to axisymmetric shells (cylinders, cones, spheres) and associated circular or annular plates, beam section rings and stringer stiffeners, where they form part of the complete structure. (5) Single shell panels (cylindrical, conical or spherical) are not explicitly covered by EN 1999-1-5. However, the provisions can be applicable if the appropriate boundary conditions are duly taken into account. (6) Types of shell walls covered in EN 1999-1-5 can be (see Figure 1.1): - shell wall constructed from flat rolled sheet with adjacent plates connected with butt welds, termed “isotropic”; - shell wall with lap joints formed by connecting adjacent plates with overlapping sections, termed “lap-jointed”; - shell wall with stiffeners attached to the outside, termed “externally stiffened” irrespective of the spacing of stiffeners; - shell wall with the corrugations running up the meridian, termed “axially corrugated”; - shell wall constructed from corrugated sheets with the corrugations running around the shell circumference, termed “circumferentially corrugated”. [Figure 1.1 - Illustration of cylindrical shell form] (7) The provisions of EN 1999-1-5 are intended to be applied within the temperature range defined in EN 1999-1-1. The maximum temperature is restricted so that the influence of creep can be neglected. For structures subject to elevated temperatures associated with fire, see EN 1999-1-2. (8) EN 1999-1-5 does not cover the aspect of leakage. 1.2 Assumptions (1) The general assumptions of EN 1990 apply. (2) The provisions of EN 1999-1-1 apply. (3) The design procedures are valid only when the requirements for execution in EN 1090-3 or other equivalent requirements are complied with. (4) EN 1999 is intended to be used in conjunction with: - European Standards for construction products relevant for aluminium structures; - EN 1090-1, Execution of steel structures and aluminium structures - Part 1: Requirements for conformity assessment of structural components; - EN 1090-3, Execution of steel structures and aluminium structures - Part 3: Technical requirements for aluminium structures.

EN 1998-2 is intended to be applied to the design of new bridges in seismic regions. It covers the design of reinforced concrete, steel and composite steel-concrete bridges and provides guidance for the design of timber bridges. EN 1998-2 is applicable to the seismic design of bridges exploiting ductility in structural members or through the use of antiseismic devices. When ductility is exploited, this part primarily covers bridges in which the horizontal seismic actions are mainly resisted through bending of the piers or at the abutments; i.e. of bridges composed of vertical or nearly vertical pier systems supporting the traffic deck superstructure. It is also applicable to the seismic design of arched bridges, although its provisions should not be considered as fully covering these cases. Suspension bridges and masonry bridges, moveable bridges and floating bridges are not included in the scope of EN 1998-2.

(2) This document contains the basic performance requirements and compliance criteria applicable to geotechnical structures and geotechnical systems in seismic regions. (3) This document refers to the rules for the representation of seismic actions and the description of the seismic design situations defined in EN 1998-1-1 and provides specific definition of the seismic action applicable to geotechnical structures. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document.

 

1.1 Scope of EN 1998-1-1 (1) This document is applicable to the design and verification of buildings and other structures for earthquake resistance. It gives general rules relevant to all types of structures, except for structures belonging to consequence classes CC0 or CC4. NOTE For further details on consequence class CC4, see 4.2. (2) This document provides basic performance requirements and compliance criteria applicable to buildings and other structures for earthquake resistance. (3) This document gives rules for the representation of seismic actions and the description of the design seismic situations. NOTE Certain types of structures, dealt with in other parts of Eurocode 8, need supplementary rules which are given in those relevant Parts. (4) This document contains general methods for structural analysis and verification under seismic actions, including base-isolated structures and structures with distributed dissipative systems. (5) This document contains rules for modelling and verification of ultimate strengths and deformations. 1.2 Assumptions (1) The assumptions of EN 1990 apply to this document. (2) It is assumed that no change in the structure and in the masses carried by the structure takes place during the construction phase or during the subsequent life of the structure with respect to the design unless proper justification and verification is provided. This applies also to ancillary elements (see 3.1.2). Due to the specific nature of seismic response, this applies even in the case of changes that lead to an increase of the structural resistance. (3) The design documents are assumed to indicate the geometry, the detailing, and the properties of the materials of all structural members. If appropriate, the design documents are also assumed to include the properties of special devices to be used and the distances between structural and ancillary elements. The necessary quality control provisions are assumed to be specified. (4) Members of special structural importance requiring special checking during construction are assumed to be identified in the design documents and the verification methods to be used are assumed to be specified. (5) It is assumed that in the case of high seismic action class (4.1.1(4)), formal quality system plans, covering design, construction, and use, additional to the control procedures prescribed in the other relevant Eurocodes, are specified.

WARNING Persons using this document should be familiar with normal laboratory practices. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to determine the applicability of any other restrictions. IMPORTANT — It is absolutely essential that tests conducted according to this document be carried out by suitably trained staff. This document specifies methods to determine 99Tc by liquid scintillation counting (LSC) in water supplies, drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling, handling, and test sample preparation. The detection limit depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The minimum detectable activity of the methods described in this document, using currently available LSC apparatus, is approximately 5 Bq·l-1 to 20 Bq·l-1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l-1).[4] These values can be achieved with a counting time of 60 min for a sample volume varying between 14 ml to 40 ml. The method presented in this document is not intended for the determination of ultra-trace activity concentrations of 99Tc. The method described in this document is applicable in the event of an emergency situation, but not if 99mTc is present at quantities that could cause interference and not if 99mTc is used as a recovery tracer. Filtration of the test sample is necessary for the methods described in this document if suspended solids are present as the methods presented in this document can only be used to determine soluble 99Tc. The analysis of 99Tc adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is made on the different phases obtained. The final activity is the sum of all the measured activity concentrations. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.
