Full title and description

SHNK 2.01.20-16 (ШНК 2.01.20-16) — "Construction of transport works in seismic regions" (Строительство транспортных сооружений в сейсмических районах).

Abstract

National technical standard providing requirements and recommendations for the design, calculation and construction of transport infrastructure (roads, bridges, tunnels, culverts and related structures) located in seismic zones. The 2016 SHNK 2.01.20-16 text (approx. 30 pages) has been superseded by an updated edition, SHNK 2.01.20-24.

General information

• Status: Superseded — replaced by SHNK 2.01.20-24 (current version).
• Publication date: 2016 (original issue; implemented in Tashkent, 2016).
• Publisher: Part of the SHNK series of Uzbek national construction norms (issued under the Republic of Uzbekistan national construction/standards system — SHNK series).
• ICS / categories: Civil engineering / transport works; relevant ICS groups include bridge and tunnel construction and road engineering (e.g., 93.040, 93.060, 93.080).
• Edition / version: SHNK 2.01.20-16 (2016 edition).
• Number of pages: ~30 pages (PDF/electronic format in common distributors' catalogs).

Scope

Sets out principles, calculation rules and constructive requirements for transport structures in seismic regions — including seismic loads, dynamic effects on soil and structures, design of bridge supports and bearings, requirements for earthworks and slopes on road alignments, tunnels and drainage structures, and recommended anti-seismic measures for foundations and superstructures. The document is intended for projects executed within the national regulatory framework of Uzbekistan and for practitioners working on transport infrastructure in seismic-prone areas.

Key topics and requirements

• Assessment and classification of seismic hazard for transport site selection and routing.
• Rules for seismic load determination and combinations with other actions (dead, live, traffic, impact).
• Design and detailing rules for bridges (piers, bearings, expansion joints) under seismic actions.
• Seismic design approaches for tunnels, culverts and retaining structures (including soil-structure interaction).
• Requirements for foundations, pile works and ground improvement in seismic zones.
• Recommendations for anti-seismic measures: seismic isolation, ductile detailing, and resilience of critical transport links.
• Inspection, maintenance and retrofit guidance for existing transport structures in seismic regions.

Typical use and users

Used by structural and geotechnical engineers, bridge and tunnel designers, transport infrastructure planners, construction contractors, technical supervisors and national/regional regulators responsible for safe design and construction of roads, bridges and tunnels in seismic areas. Also used as a reference in academic and research work on seismic design of transport facilities.
