TQS is a professional structural engineering software suite developed by the Brazilian company TQS Informática for the analysis, design, detailing and drawing of building structures — mainly reinforced and prestressed concrete and other structural elements.

Integrated structural design platform: TQS isn’t just one tool — it’s a set of software systems that work together to handle the full structural engineering workflow, from model creation and structural analysis through reinforcement detailing and plan generation.

Focused on reinforced concrete and related structures: Many modules support design and checks under Brazilian technical norms (ABNT), but the software is also used internationally in projects where similar codes and workflows apply.

Productivity and BIM-ready: It’s designed to automate repetitive engineering tasks and is compatible with BIM (Building Information Modeling) workflows.

Depending on the specific package or module, TQS can be used for:

Structural modeling and analysis of buildings — calculating loads, forces, deflections, etc.Automatic generation of reinforcement drawings and structural plans.Design and detailing of reinforced concrete and prestressed components like slabs, beams, walls, columns.Specialized tools — for example for reservoir design, retaining walls, carbon-fiber strengthening, wind loads from tunnel data, and more.
Example Modules in the TQS Ecosystem:

TQS Full / Student / EPP+ packages: Different versions tailored to project size and user needs (student/educational, small buildings, or full professional designs).Reservoir design software: For tank calculations and detailing.CONTEN: For design of retaining walls.PREF: For carbon fiber structural strengthening.
