From CAD Model to Code-based Checks and the Technical Report in Minutes. The only software dedicated entirely to the linear and non-linear assessment and strengthening of existing buildings.

SeismoBuild is an innovative Finite Element package built from the ground up for the seismic assessment and retrofitting of reinforced concrete (RC) structures. Unlike general-purpose structural software, SeismoBuild automates the entire process: from intuitive structural modelling and non-linear analysis (Pushover & Dynamic) to code-based verification, the export of CAD drawings and the technical report generation.

It is the ultimate tool for engineers who need to carry out code-compliant Structural Vulnerability Assessment, and Seismic Retrofit Design with speed, accuracy, and scientific rigor.

FRP Designer

FRP Designer Included

Since the 2023 version of SeismoBuild the new FRP Designer application is included in the installation.

FRP Designer provides an efficient solution for designing FRP strengthening of reinforced concrete columns and beams by computing the strength of reinforced concrete members strengthened with FRP laminates.

Designed for Seismic Engineering Professionals

  • For Structural Engineering Firms

  • For Retrofitting Consultants

  • For Researchers & Experienced Scientists

The Use Case: High-volume assessment and retrofitting projects.

The Solution: Drastically reduce the time spent on modelling and post-processing. SeismoBuild automates the calculation of Target Displacement in Pushover analysis, checks the necessary code requirements (e.g., shear, chord rotation, inter-story drift) automatically, and produces fully customizable technical reports ready for submission.

The Use Case: Strengthening existing, vulnerable buildings.

The Solution: Easily model and compare various strengthening strategies. Apply Shotcrete Jackets with steel dowels, new Shear Walls, Fiber Reinforced Polymers (FRPs), Steel Braces, Base Isolation or Steel Exoskeletons with just a few clicks. The software automatically recalculates the increased structural capacity to fix common defects like short columns, soft-story mechanisms, or inadequate confinement.

The Use Case: High-fidelity non-linear simulation.

The Solution: While automated, SeismoBuild does not compromise on accuracy. It employs both the lumped-plasticity (plastic hinge) approach, and the distributed plasticity (fiber-based) approach, allowing for flexibility and the realistic nonlinear modelling of the structural elements. It enables sophisticated sensitivity analyses and supports the automatic generation of artificial accelerograms adapted to the specified code-based spectra (via SeismoArtif integration).

A Complete Assessment Workflow in One Interface

1. Intuitive Building Modelling

No need for complicated procedures and complex scripting for the structural input. Import your CAD drawings (DWG/DXF), and SeismoBuild allows you to work with real building objects—columns, shear walls, beams and slabs. The structural model is then automatically created with just one click by SeismoBuild’s Building Modeller, which is able to handle complex building geometries with ease.

  • New in v2026: Full integration of Steel Members allows for the modeling of mixed RC-Steel structures or steel components within RC frames.

2. Powerful Non-Linear Analysis

Execute rigorous Non-Linear Static (Pushover) Analysis and Non-Linear Dynamic (Time-History) Analysis. SeismoBuild’s parallel solver considers both material inelasticity and geometric nonlinearities and it is optimized for stability and speed.

3. Automatic Code Verification & Compliance

Forget manual spreadsheets. SeismoBuild facilitates compliance with major codes for structural assessment and strengthening, including Eurocode 8 Part-3 (European Standards), ASCE 41-23 (US standards), NTC-18 (Italian standards), KANEPE (Greek standards) and TBDY 2018 (Turkish standards).

It automatically checks every member against the code-defined acceptance criteria, including:

  • Chord Rotation
  • Bending Moments
  • Member Shear Capacity
  • Inter-story Drifts
  • Beam-Column Joints
  • Strain and Deformation Capacity
  • Buckling of Steel Members
  • Checks for individual Footings and Strip Footings

4. Strengthening & Retrofitting

Test rehabilitation scenarios instantly. Select existing members and apply with a few clicks:

  • Concrete Jackets: Customize jacket thickness, sides and reinforcement.
  • FRP Wrapping: SeismoBuild v2026 supports FRP strengthening for Beams & spacing control of the FRP fabrics
  • New RC Shear Walls: Enhance strength, stiffness and ductility.
  • Steel Braces: Enhance strength, stiffness and ductility with steel braces of different configurations (e.g., X-shaped, diagonal, chevron).
  • Base Isolation: It decouples the building from its foundation using flexible bearings, significantly reducing shaking and damage

5. The Technical Report

Generate a comprehensive, professional PDF report that includes all model data, analysis results, code verification checks, and detailed plots.

6. The CAD Drawings

Export the CAD drawings of the modelled building, including, plan views, member cross-sections and reinforcement tables.

Why Choose SeismoBuild?

  • Dedicated to Assessment: Unlike other similar software packages (Revit, ETABS, SAP2000 , STAAD.Pro, and Midas GEN), which are designed primarily for new buildings and linear elastic analysis, SeismoBuild is dedicated to existing buildings and focuses mainly on the nonlinear static and dynamic analytical procedures, which are more suitable for the assessment of existing buildings.

  • Global Code Support: Built-in support for Eurocode 8 (Part 3), ASCE 41-23, NTC-18 (Italy), KANEPE (Greece), TBDY 2018 (Turkey).

  • Productivity: What takes days in general FEA software takes hours in SeismoBuild due to the automated procedures in the model creation, the code-based checks and the reporting.

New Features in v2026

  • Steel Members & Checks: Model and verify steel elements within your RC project.

  • Advanced FRP Capabilities: Now supports FRP modeling for beams and detailed spacing controls for the FRP fabrics.

  • AI Assistant: Integrated support to speed up your workflow and answer technical queries instantly.

Ideal For:

  • Structural Assessment & Seismic Vulnerability Evaluation

  • Designing Seismic Retrofit Interventions
  • Performance-Based Design (PBD) projects
