In the field of steel structure engineering, the complexity of design, construction, and project management places stringent demands on the precision and efficiency of tools. From 3D modeling and structural analysis to construction animation and material takeoff generation, specialized software has become an indispensable core tool for engineers seeking to enhance productivity and ensure quality. This paper reviews the widely used, practical software solutions currently employed in steel structure projects, covering the entire workflow—from design and detailing to construction and project management—to provide practitioners with a reference for technology selection.

1. PKPM/YJK

The “dominant player” in China’s architectural structural design field excels in steel structure analysis:

Built-in code parameters, including China’s “Code for Design of Steel Structures,” automatically generate calculation reports that comply with review and approval requirements.

Integrates modeling, analysis, and construction drawing generation functions, and supports data interoperability with software such as 3D3S.

Essential calculation software for the domestic construction engineering field; it does not require a strong technical background, as many parameters are pre-packaged and built into the software. Its drawback is that it can hinder the development of a structured knowledge framework.

Scope of application for steel structures: Standard steel structures such as steel frames, portal frames, space trusses, and lattice trusses can all be analyzed using conventional methods.

2. 3D3S

The “national software” in China’s steel structure design field, developed on a CAD platform, boasts the following advantages:

Deeply aligned with Chinese codes and standards, it features a built-in library of commonly used steel member cross-sections to simplify parameter configuration.

Offers specialized functions such as space frame design and form-finding for cable-membrane structures, supporting the design of all types of structures—from portal frames to spatial trusses.

Essential design software for domestic steel structure design.

3. Tekla Structures

As a benchmark software for global steel structure detailing, Tekla is renowned for its “what you see is what you get” 3D modeling capabilities. Its core strengths lie in:

From model creation and collision detection to the generation of fabrication shop drawings, the solution supports automatic component numbering and bill-of-materials export, thereby reducing human error.

Built-in with a vast library of standardized nodes, supporting parametric customization to meet complex connection design requirements;

Typical application scenarios include super-tall buildings, bridges, and irregular steel structures; for example, the detailed design of the National Stadium “Bird’s Nest” was completed using Tekla.

Essential software for in-depth design at domestic steel structure fabrication plants: design institutes rely on PKPM and YJK just as steel structure fabricators rely on Tekla.

4. MIDAS Gen

A general-purpose structural analysis software developed in South Korea, renowned for its “ease of use” and “high-efficiency computation”;

Adopts a tree-style menu and graphical interface to lower the learning curve;

For multi-story steel structure optimization algorithms, the computation speed is more than 30% faster than that of conventional software.

In China, learning finite element software for structural analysis typically begins with MIDAS GEN.

4. SAP2000

Internationally recognized structural analysis software, adept at handling complex spatial structures:

Supports linear and nonlinear static analysis, dynamic time-history analysis, and wind-induced vibration response simulation;

It can accurately analyze the structural behavior of large-span venues and high-rise buildings under extreme loads such as earthquakes and typhoons.

It is generally suitable for use in finite element post-processing analysis.

5. IDEA StatiCa

The undisputed champion of steel structure joint analysis;

Supports custom modeling and features interfaces with BIM software for direct import of nodes;

It boasts an extremely rich node library, and node DIY is also very convenient;

Compliant with domestic steel structure codes.

6. STAAD.Pro

For international structural analysis projects, this software is essential.

Integration of modeling, analysis, design, and optimization;

Supports a wide range of material types and structural configurations, making it suitable for engineering projects of varying complexity, from simple to highly intricate.

Comply with structural design codes and standards in multiple countries and regions worldwide to ensure design compliance.
