What is Free Structural Engineering Software?

Structural engineering software is designed to provide engineers with the tools to efficiently and accurately analyze, design, and optimize building structures. This software often offers a wide range of calculations for steel, concrete, and timber designs, allowing the user to quickly conduct structural analysis. Structural engineering software also provides 3D modeling capabilities which enable visualization of layout plans as well as generate clear drawings. In addition, these programs are often accompanied by pre-defined library elements such as walls, beams, columns and slabs which save time during the design process. Finally, some packages may include an optimizer module that assists in finding the most economical structural design solution.

RFEM

Dlubal Software

The FEA program RFEM allows for quick and easy modeling, structural and dynamic calculation, as well as the design of models with member, plate, wall, folded plate, shell, and solid elements. Due to the modular software concept, you can connect the main program RFEM with the corresponding add‑ons in order to meet your individual requirements. The structural analysis program RFEM provides structural engineers with a 3D FEA program that meets all requirements in modern civil engineering. Efficient data input and intuitive handling facilitate the modeling of simple and complex structures. The structural analysis program RFEM is the basis of a modular software system. The basic program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as model solid and contact elements.

RSECTION

Dlubal Software

Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis. With the stand-alone program RSECTION, Dlubal Software provides you with a time-saving solution for the calculation of thin-walled and massive cross-sections. The program determines the section properties and performs a stress analysis. The seamless integration with the FEA software RFEM and the structural frame & truss analysis software RSTAB allows for efficient cooperation. RSECTION cross-sections are available in the RFEM and RSTAB libraries, and you can easily import the internal forces in the programs.

RSTAB

Dlubal Software

RSTAB is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering. Use the successful structural frame & truss analysis software RSTAB for your design of beam, frame, or truss structures consisting of steel, reinforced concrete, timber, aluminum, or other materials. With RSTAB, you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. There are design add-ons at your side that you can use to consider the material- and standard-specific requirements.
