Eurocode 3 - Design of steel structures - Part 1-6: Strength and stability of shell structures

1.1 Scope (1) EN 199316 provides rules for the structural design of plated steel structures that have the form of a shell of revolution (axisymmetric shell). (2) This document is applicable to unstiffened fabricated axisymmetric shells formed from isotropic rolled plates using both algebraic and computational procedures, and to stiffened axisymmetric shells with different wall constructions using computational procedures. It also applies to associated circular or annular plates and to beam section rings and stringer stiffeners where they form part of the complete shell structure. The general computational procedures are applicable to all shell forms. (3) This document does not apply to manufactured shells or to shell panels or to elliptical shell forms, except that its computational procedures are applicable to all shell structures. This document does not apply to structures under seismic or other dynamic loading. It does not cover the aspects of leakage of stored liquids or solids. (4) Cylindrical and conical panels are not explicitly covered by this document. However, the provisions of 9.8 can be used provided that appropriate boundary conditions are taken into account. (5) This document defines the characteristic and design values of the resistance of the structure. (6) This document is concerned with the requirements for design against the ultimate limit states of: — plastic failure; — cyclic plasticity; — buckling; — fatigue. (7) Overall equilibrium of the structure (sliding, uplifting, overturning) is not included in this document. Special considerations for specific applications are included in the relevant application parts of EN 1993. (8) Detailed formulae for the simple calculation of unstiffened cylinders, cones and spherical domes are given in the Annexes. (9) Provisions for simple calculations on specific stiffened shell types are given in EN 199341. (10) This document is intended for application to steel shell structures. Where no standard exists for shell structures made of other metals, including high strength steels, the provisions of this document are applicable provided the appropriate material properties of the metal are taken into account. (11) The provisions of this document are intended to be applied within the temperature ranges defined in the relevant EN 1993 application parts. (12) Where no application part defines a different range, this document applies to structures within the following limits: — design metal temperatures lie within the range −50 °C to +100 °C, except when using the special provisions given in 5.1; — radius to thickness ratios (r/t) within the range 50 to 2 000; — manufactured circular hollow sections according to EN 10210 and EN 10219 are outside the scope of this document and are covered by EN 199311. However, if no other provisions are available, the rules of this document are useful for manufactured circular hollow sections. In particular, this document is applicable to the design of manufactured piles (see EN 19935) provided the imperfections and tolerance requirements of EN 19935 are adopted in place of those specified in this document, and where no other standard covers the specific pile geometry. NOTE 1 Experimental and theoretical data relating to manufactured circular hollow sections were not considered when this document was drafted. The application of this document to such structures therefore remains the responsibility of the user. NOTE 2 The stress design rules of this document can be rather conservative if applied to some geometries and loading conditions for relatively thickwalled shells. NOTE 3 Thinner shells than r/t = 2 000 can be treated using these provisions but the provisions have not been verified for such thin shells. NOTE 4 The maximum temperature is restricted so that the influence of creep can be ignored where high temperature creep effects are not covered by the relevant application part. [...]

Plastics - Determination of tensile properties - Part 6: Measurement of strain distribution for randomly oriented chopped strand- or fibre- reinforced plastic composites (ISO/DIS 527-6:2026)

This document outlines methods for measuring the strain distribution for randomly oriented chopped strand- or fibre-reinforced plastic composites, based upon the general principles given in ISO 527-4. The methods are used to statistically evaluate the inherent variation of strain-based properties. The main purpose of this document compared to existing standards is to evaluate the strain distribution due to the random orientation of chopped fibres, while ISO 527-4 is sufficient for evaluating only the bulk elastic modulus. This standard provides two methods for evaluating an inherent strain distribution of the material, Method A as using DIC analysis system and Method B as using several strain gauges with a short gauge length. The methods are suitable for use with fibre-reinforced thermosetting and thermoplastic composites incorporating discontinuous or chopped reinforcements such as mats, chopped strands or tapes, long-fibre injection or combination of such reinforcements. The methods are not normally suitable for continuous fibre-reinforced materials which generate homogeneous strain distribution on the surface of the test specimen.

Textiles - Oil repellency - Hydrocarbon resistance test (ISO/FDIS 14419:2026)

This document specifies a method for the evaluation of a substrate's resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions. This document provides guidance to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the oil repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This document can also be used to determine if washing and/or drycleaning treatments have any adverse effect on the oil repellency characteristics of a substrate. NOTE 1        Washing and drycleaning treatment procedures are described in ISO 6330 and ISO 3175 (all parts), respectively. This document is not intended to give an absolute measure of the resistance of the substrate to staining by all oily materials. Other factors, such as composition and viscosity of the oily substances, substrate construction, fibre type, dyes and other finishing agents, also influence stain resistance. This document is not intended to estimate the resistance to penetration of the substrate by oil-based chemicals. NOTE 2        For the evaluation of the resistance to penetration of the substrate by oil-based chemicals, see ISO 6530.

Execution of special geotechnical work - Diaphragm walls

This European Standard establishes general principles for the execution of diaphragm walls as either retaining walls or cut-off walls. NOTE 1 This standard covers only structures constructed in a trench excavated with a support fluid or in dry conditions, where soil is removed and replaced by concrete or slurry and with wall thickness B ≥ 40 cm. NOTE 2 Diaphragm walls can be permanent or temporary structures. NOTE 3 The following types of structure are considered: a) retaining walls: usually constructed to support the sides of an excavation in the ground. They include: 1) cast in situ concrete diaphragm walls; 2) precast concrete diaphragm walls; 3) reinforced slurry walls; b) cut-off walls: usually constructed to prevent migration of groundwater, clear or polluted, or of other contaminants present in the ground. They include: 1) slurry walls (possibly with membranes or sheet piles); 2) plastic concrete walls. NOTE 4 Walls formed shallow vertical trenches (typically excavations with a ratio of depth over thickness D/B < 5 or D < 5 m) are not covered by this standard.

Geosynthetics - Test method for determining the resistance of polymeric geosynthetic barriers to environmental stress cracking

This document specifies a test method for screening the resistance of polymeric geosynthetic barriers to stress cracking. The test is applicable to polypropylene and polyethylene based products and to all other polymeric geosynthetic barriers which have a partially crystalline structure. NOTE The described method is suitable for conformance testing of smooth surfaced (non-textured) geosynthetic barriers. However the resistance to stress cracking of the resin used in the manufacture of structured surface materials can be evaluated by carrying out the test on a plaque formed from the relevant resin (see 4.5) or, where structuring is carried out as a separate processing step, on a preformed smooth surface geosynthetic barrier, the test can be performed on the intermediate smooth material. The data are suitable for screening and determination of conformity but not for deriving performance data such as lifetime, unless supported by further evidence.
