Full title and description

SP 26.13330.2012 — "Foundations for machines with dynamic loads" (Russian: СП 26.13330.2012, Фундаменты машин с динамическими нагрузками). This document is the updated SP (Свод правил) edition that modernises and replaces provisions from the older СНиП 2.02.05-87 and is published with Amendment No. 1 (2016).

Abstract

SP 26.13330.2012 provides technical requirements, calculation methods and constructive rules for the design and construction of foundations for machines and equipment subject to dynamic (vibratory and impact) loads. It covers assessment of dynamic effects, vibration and frequency checks, selection and arrangement of foundation bolts and anchors, reinforcement and jointing of massive foundations, soil–foundation interaction and protective measures for foundations exposed to aggressive environments. The published text includes official amendments issued in 2016.

Scope

Defines compulsory and recommended requirements for design, calculation and constructive solution of foundations for stationary machines and equipment that generate dynamic loads (vibratory, impact, rotating machinery, reciprocating machines, etc.). The scope includes selection of foundation type (massive, framed, piled), checks for strength and serviceability under combined static and dynamic actions, calculation of natural frequencies and amplitudes, layout and design of anchor/foundation bolts, reinforcement and joints, measures for protection from groundwater and aggressive media, and requirements for geotechnical investigation and soil–foundation interaction. The document is presented as an updated/recast edition of the older СНиП 2.02.05-87 rules.

Key topics and requirements

• Methods for dynamic analysis of foundations: calculation of natural frequencies, dynamic stiffness coefficients, and verification of resonance conditions.
• Rules for choosing foundation types (massive slab, framed/raft, pile foundations) depending on machine type and soil conditions.
• Detailed requirements for foundation bolts, anchors and embedded parts (types, installation, spacing and minimum embedment), including guidance for removable bolts under certain dynamic/impact conditions.
• Design and reinforcement rules for foundation bodies: base plate and local reinforcement under machine soleplates and areas of stress concentration.
• Serviceability limits for vibration and criteria where workplace vibration and equipment operation require additional checks (human exposure and technological limits).
• Geotechnical investigation and soil parameters for dynamic design, including adjustments to normative references (updates to referenced GOSTs and SPs via Amendment No. 1).
• Construction joints, temperature/settlement joints and recommendations to avoid adverse effects from shrinkage, thermal deformation and differential settlements.
• Protective measures for foundations in aggressive environments and for structures built on problematic grounds (permafrost, compressible layers, high groundwater).

Typical use and users

Primary users are structural and geotechnical engineers, machinery installation engineers, plant designers, construction contractors and inspectors who design, review or build foundations for heavy rotating and reciprocating equipment, turbines, compressors, presses, generators, mills and other machinery producing dynamic forces. Regulatory authorities and certification bodies also use SP 26.13330.2012 as the normative basis for approving designs and site acceptance tests.

Related standards

SP 26.13330.2012 references and is linked with earlier СНиП 2.02.05-87 (now updated), other SPs and relevant GOSTs. Notable related documents and references include: SNIP / SP series on geotechnical investigation and foundation design (for example SP 47.13330.x and SP 28.13330.x as normative cross-references), and national GOST standards for soils (e.g., GOST 25100-2011) and testing methods updated by the 2016 amendment. These referenced standards provide complementary requirements for soil classification, laboratory testing and protective measures.

FAQ

Q: What is this standard?

A: SP 26.13330.2012 is the Russian "Svod Pravil" (SP) that sets out design and construction requirements for foundations of machines subject to dynamic loads; it is the updated normative edition corresponding to the older СНиП 2.02.05-87.

Q: What does it cover?

A: It covers calculation methods for dynamic effects (frequencies and amplitudes), selection and arrangement of foundation types and anchors, reinforcement and jointing of foundations, geotechnical input data for dynamic design, and protective measures for aggressive environments and special ground conditions.

Q: Who typically uses it?

A: Structural and geotechnical engineers, plant and machinery designers, installation contractors, construction supervisors and regulatory bodies responsible for approving machine foundation designs and on-site acceptance testing.

Q: Is it current or superseded?

A: The SP 26.13330.2012 edition entered into force 1 January 2013 and was officially amended (Amendment No. 1) by a Ministry order published 18 August 2016; it is published as the current SP text (users should check national registers for later revisions or additional amendments).

Q: Is it part of a series?

A: Yes — it is published as part of the Russian SP (Свод правил) system and functions as the updated/recast edition for the subject previously covered by СНиП 2.02.05-87; it cross-references other SP and GOST documents relevant to geotechnical and concrete design.
