GOST 14098-2014 PDF

Full title and description

GOST 14098-2014 — "Welded joints of reinforcement and inserts for reinforced concrete structures. Types, constructions and dimensions". The standard defines types, structural designs and dimensional parameters for welded connections of bar and wire reinforcement and for welded connections of reinforcement with sheet and shaped rolled products used in manufacture and assembly of reinforced concrete elements.

Abstract

This standard establishes constructions, essential dimensions and recommended welding methods (resistance and arc welding) for welded joints of reinforcement and embedded (insert) parts used in prefabricated and monolithic reinforced concrete structures. It is intended to ensure interchangeability, manufacturability and reliable performance of welded reinforcement and embedded assemblies.

General information

• Status: Active (in force; replaces ГОСТ 14098-91).
• Publication date: Edition 2014; introduced into force 01 July 2015.
• Publisher: Interstate/ Russian standards system (GOST / developed by ОАО НИЦ «Строительство»).
• ICS / categories: 91.080.40 (Concrete and reinforced concrete structures).
• Edition / version: 2014 edition (current text with later amendments and corrigenda noted in official indexes).
• Number of pages: 40 (official published text).

Scope

Applies to welded joints of rod and wire reinforcement and to welded joints of rod reinforcement with sheet and shaped rolled products used in manufacture of reinforcement and embedded parts, and during assembly of prefabricated and erection of monolithic reinforced concrete structures. The standard covers joints produced by contact (resistance) and arc welding and does not apply to embedded items that lack anchor bars of reinforcement steel.

Key topics and requirements

• Classification of welded joint types (butt, lap, T/fillet, combined and special embedded connections) and standardized geometric configurations.
• Dimensional tables for joint geometry before and after welding (clearances, overlaps, residual depressions, summed thicknesses, etc.).
• Permitted welding methods: resistance (contact) welding and various arc-welding variants; guidance on selection of rational joint types and welding procedures.
• Technical requirements for design substitution and for manufacture of joints not covered explicitly (require development of working drawings and technological descriptions).
• References to material requirements (chemical composition and carbon equivalent limits for certain reinforcement steel classes) and cross-references to related GOSTs for reinforcing steels and welding practice.

Typical use and users

Used by structural engineers, reinforcement fabricators, concrete product manufacturers, construction contractors (both precast and in-situ reinforced concrete), welding technologists, and quality/inspection personnel to specify, produce and verify welded reinforcement and embedded items in building and civil works. Also used by design institutes preparing reinforcement and embedded part drawings.

Related standards

Commonly referenced standards include GOST 10922 (general specifications for reinforcing and embedded products), GOST 34028 (requirements for reinforcing rolled products), GOST 5264 and GOST 8713 (welding types and main design elements), and subsequent national texts such as GOST R 57997-2017 on welded reinforcement products. Normative references and cross-references are listed in the standard.

FAQ

Q: What is this standard?

A: GOST 14098-2014 is the national (GOST) standard that establishes types, constructions and dimensions of welded joints for reinforcement and embedded (insert) items used in reinforced concrete structures.

Q: What does it cover?

A: It covers welded joints of bar and wire reinforcement, welded joints of reinforcement with sheet and shaped rolled products, the recommended welding methods (resistance and arc), required joint geometries and dimensional tolerances, and related technical requirements for manufacture and assembly. It excludes embedded items without anchor reinforcement bars.

Q: Who typically uses it?

A: Structural and reinforcement designers, reinforcement fabricators, precast concrete manufacturers, construction contractors, welding engineers, and inspectors use the standard in design, production and quality control of welded reinforcement and embedded assemblies.

Q: Is it current or superseded?

A: The 2014 edition is the current GOST text introduced into force on 01 July 2015 and it replaced the earlier 1991 edition; the standard has received subsequent amendments and corrigenda indicated in official indices (IUS updates and amendments 2019–2022). Users should check the latest national index or publisher notice for any further amendments.

Q: Is it part of a series?

A: It is part of the body of Russian/GOST documents governing reinforcement, embedded items and welding in reinforced concrete construction and is cross-referenced with other GOSTs on reinforcing steel, welding practice and product specifications (for example GOST 10922, GOST 34028, GOST 5264, GOST 8713 and related national standards).

Q: What are the key keywords?

A: welded joints, reinforcement, embedded items, reinforced concrete, resistance welding, arc welding, joint dimensions, fabrication, welding procedures.
