The 2018 version abolished the older methods for calculating soil-structure interaction and reintroduced a simplified method based on the qc cone resistance from CPT tests. In English, this translates to a stricter requirement for geotechnical investigations.
Despite its technical merits, adopting NTC 2018 presents real-world difficulties:
Rating: 3.5/5 Stars
The NTC 2018 English material is Essential for Foundations, but Insufficient for Mastery.
How to use it effectively: Do not use it as your only study material. Use the 2018 guide to learn how to write the essays and understand the format. Then, immediately move to 2021, 2022, and 2023 past papers to understand the current difficulty level and the specific demands of the new curriculum.
Note: If you were referring to a technical engineering standard (like the National Transport Commission or a specific ISO standard) or a different "NTC" context, please clarify, and I will happily provide a review for that specific document!
The NTC 2018 (Norme Tecniche per le Costruzioni) is the Italian set of technical regulations governing the design, construction, and renovation of buildings. An official full-length English translation is not always hosted as a single primary document by the Italian government, but comprehensive technical versions and related reports are available through various engineering and regulatory portals.

You can find the following English-language resources for NTC 2018:
Official Notification Text: A partial English translation of the decree (Ministerial Decree of 17 January 2018) is available on the European Commission Technical Regulation Information System
Technical Design Manuals: Detailed English manuals, such as the SFD NTC 2018 (Steel Frame Design Manual)
, explain the design algorithms and parameters required by the code.
Specific Structural Reports: Specialized English reports, like the NTC 2018 Non-Structural Walls Report, provide translated tables and coefficients for structural actions.
Application Guidelines: Information on the accompanying Circular No. 7 of 21.01.2019, which clarifies the NTC 2018 rules, can be found on sites like Tecnopiemonte. Core Components of NTC 2018 The 2018 version abolished the older methods for
The standards are heavily based on the Eurocodes (EN 1990 - EN 1999) and cover several key areas:
Seismic Safety: Requirements for earthquake-resistant designs in reinforced concrete, steel, and masonry.
Limit States: Defines Operational (SLO/SLD) and Ultimate (SLV/SLC) limit states for structural verification.
Material Properties: Specifies characteristics for various building materials, including steel, masonry, and concrete.
Geotechnical Design: Aligns with EN 1997 (EC7) for foundations and soil interactions.

The NTC 2018 (Norme Tecniche per le Costruzioni) is Italy's primary technical code governing the design, execution, and testing of buildings and civil engineering structures.
For international engineering firms and researchers, the English version is a critical resource for applying these rigorous seismic and structural standards to projects within Italy or for comparative international study. Key Features of NTC 2018
Performance-Based Seismic Design: Unlike older prescriptive codes, NTC 2018 emphasizes "Performance Objectives." Structures are designed to meet specific safety and usability levels—such as Operational (OLO), Damage (SLD), Life Safety (SLV), and Collapse Prevention (SLC)—based on the intensity of seismic events.
Harmonization with Eurocodes: The 2018 update significantly narrowed the gap between Italian national standards and the Eurocodes (EN 1990 – EN 1999). This allows engineers familiar with European standards to adapt more easily, though NTC 2018 maintains specific National Annexes and unique Italian geographic seismic parameters.
Existing Buildings Framework: One of the most robust sections of the code covers the assessment and "retrofitting" (Miglioramento) or "upgrading" (Adeguamento) of older masonry and RC structures. It provides clear methodologies for determining the "Knowledge Level" (LC1, LC2, LC3) of a building, which dictates the confidence factor applied during calculations.
Geotechnical Integration: NTC 2018 mandates a holistic approach where geotechnical design is not a separate entity but is integrated into the structural safety analysis. This includes refined requirements for soil characterization and the interaction between foundations and the superstructure.
Material Durability and Traceability: The code places heavy emphasis on the quality control of construction materials. It requires strict certification for steel, concrete, and innovative materials (like FRPs for reinforcement), ensuring that every component of a structure is traceable and meets standardized strength benchmarks.
Major structural software packages (SAP2000, Midas Gen, STRAUS, and Pro_SAP) have all released NTC 2018 modules. However, the English version of the code is critical for setting up the software correctly.
