Eurocode 3 - Design of steel structures - Part 1-14: Design assisted by finite element analysis

kSIST FprEN 1993-1-14:2025

1.1   Scope of prEN 1993-1-14
(1) This document gives principles and requirements for the use of numerical methods in the design of steel structures, more specifically for the ultimate limit state (including fatigue) and serviceability limit state verifications. It also gives principles and requirements for the application of advanced finite element (FE) and similar modelling techniques for numerical simulation which also covers safety assessment.

b)   cold-formed members and sheeting,
c)   welded plated profiles,
d)   stainless steel profiles,

Eurocode 8 - Design of structures for earthquake resistance - Part 3: Assessment and retrofitting of buildings and bridges

kSIST FprEN 1998-3:2025

1.1   Scope of EN 1998-3
(1)   This document is applicable to the assessment and retrofitting of buildings and bridges in seismic regions, namely as given in a) to c):
a)   to provide criteria for the assessment of the seismic performance of existing individual buildings and bridges;
b)   to describe the procedure to be followed in selecting necessary corrective measures;
c)   to set forth criteria for the design of retrofitting measures (i.e. design, structural analysis including intervention measures, final dimensioning of structural parts and their connections to existing structural members).
NOTE 1   For the purposes of this document, retrofitting covers both the seismic upgrading (e.g. strengthening or adding a passive system) of undamaged structures and the repair and possible upgrading of earthquake-damaged structures.
NOTE 2   Only the most common retrofit techniques are covered in this document. This does not exclude the use of other techniques, which can be developed in each country, based on the strengthening principles of this document.
NOTE 3   Annex D gives flowcharts for the application of this document.
(2)   Unless specifically stated, EN 1998-1-1 and EN 1998-5 apply.
(3)   Reflecting the performance requirements of EN 1998-1-1:2024, 4.1, this document covers the seismic assessment and retrofitting of buildings and bridges made of the more commonly used structural materials: concrete, steel and composite, timber and masonry.
NOTE   Annexes B and C contain additional guidance related to the assessment of timber and masonry structures, respectively, and to their retrofitting when necessary.
(4)   This document is intended for the assessment of individual structures, to decide on the need for structural intervention and to design the retrofitting measures that may be necessary. It is not intended for the vulnerability assessment of populations or groups of structures in seismic risk evaluations for various purposes (e.g. for determining insurance risk, for setting risk mitigation priorities, etc.).
(5)   This document provides (in its material-specific Clauses 8 to 11) criteria for the verification of the more common retrofitting techniques currently in use.
(6)   This document gives specific rules for the assessment and retrofitting relevant to existing buildings and bridges of consequence classes CC1, CC2 and CC3, as defined in EN 1990:2023, 4.3.
(7)   Although the provisions of this document are applicable to all common categories of buildings and bridges, the seismic assessment and retrofitting of monuments and heritage structures often requires different types of provisions and approaches, depending on the nature of the monuments and heritage structures.
1.2   Assumptions
(1)   The assumptions of EN 1998-1-1 apply to this document.
(2)   The provisions of this document assume that the data collection and tests are performed by experienced personnel and that the engineer responsible for the assessment, the possible design of the retrofitting and the execution of work has appropriate experience of the type of structures being upgraded or repaired.
(3)   It is assumed that inspection procedures, checklists and other data-collection procedures will be documented and filed and referred to in the assessment/design documents.

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

kSIST FprEN 1993-1-6:2024

1.1   Scope of EN 1993-1-6
(1) EN 1993-1-6 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 1993-4-1.
(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 1993-1-1. 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 1993-5) provided the imperfections and tolerance requirements of EN 1993-5 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 thick-walled 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.
