Commonly Used Software in Steel Structure Engineering and Fabrication

In modern steel structure engineering, professional software has become an essential tool for improving design accuracy, fabrication efficiency, and project coordination.

From structural calculation and finite element analysis to detailing, shop drawings, and workshop production management, different software platforms play different roles throughout the entire steel structure workflow.

For steel fabrication companies, software is not just a design tool. It directly affects detailing quality, workshop coordination, fabrication efficiency, and on-site installation accuracy.

Based on Henan Jingyuan’s practical experience in steel structure fabrication and engineering projects, this article introduces several commonly used software platforms in steel structure design, analysis, detailing, and fabrication.

1. PKPM / YJK

PKPM and YJK are among the most widely used structural design software platforms in China’s steel structure engineering industry.

Their main advantages include:

• Strong compatibility with Chinese steel structure design codes
• Automatic structural calculation report generation

• Efficient support for conventional steel structure analysis

In practical projects, Henan Jingyuan commonly uses PKPM or YJK for:

• Portal frame structure calculation
• Steel frame analysis
• Industrial workshop structure design
• Conventional steel structure scheme verification

For domestic steel structure projects, these software platforms help engineers complete structural calculations with high efficiency, making them widely used in design institutes and engineering companies.

However, from a practical engineering perspective, software should always serve as a supporting tool. Real project quality still depends on the engineer’s understanding of structural behavior and load transfer logic.

2. 3D3S

3D3S is a mature and widely used software platform in China’s steel structure engineering industry.

Its key features include:

• CAD-based development platform
• Built-in steel section libraries

• Workflow optimized for domestic engineering practices

In practical engineering projects, 3D3S is commonly used for:

• Portal frame design
• Space truss analysis
• Grid structure design
• Cable and membrane structure form-finding analysis

For many conventional steel structure projects, 3D3S provides stable performance and efficient engineering workflows.

Especially in small and medium-sized steel structure projects, its operation logic is highly compatible with local engineering processes.

3. Tekla Structures

For steel fabrication factories, Tekla Structures has become one of the most important software platforms for detailing and shop drawing production.

In Henan Jingyuan’s actual fabrication projects, Tekla is used not only for 3D modeling, but also for improving workshop production coordination and fabrication management.

Its core advantages include:

• 3D visual steel detailing
• Automatic shop drawing generation
• Component numbering management
• Material list export
• CNC data output
• Clash detection and node optimization

Tekla becomes especially valuable in:

• Complex steel structures
• Long-span steel structures
• Irregular steel fabrication projects
• Spatial steel structure engineering

During actual fabrication processes, Henan Jingyuan uses Tekla-generated shop drawings and component numbering systems to improve production management, reduce installation errors, and minimize fabrication rework.

For steel structure companies, design institutes often rely on PKPM or YJK, while fabrication workshops rely heavily on Tekla Structures.

4. MIDAS Gen

MIDAS Gen is one of the most commonly used finite element analysis software platforms in China’s engineering industry.

Compared with traditional analysis software, MIDAS Gen places greater emphasis on:

• User-friendly graphical operation
• Simplified workflow
• Efficient multi-story structural analysis

Its main features include:

• High modeling efficiency
• Clear tree-structured menu logic
• Fast calculation speed
• Good compatibility with complex structural analysis

In practical steel structure engineering projects, MIDAS Gen is commonly used for:

• Multi-story steel structure analysis
• Industrial workshop structural analysis
• Finite element load verification
• Complex structural calculation support

For many structural engineers, MIDAS Gen is also considered one of the most accessible entry-level finite element analysis software platforms.

5. SAP2000

SAP2000 is one of the most recognized structural analysis software platforms in the international engineering industry.

Its biggest advantage lies in its ability to perform complex spatial structural analysis.

Its primary capabilities include:

• Nonlinear analysis
• Dynamic time-history analysis
• Wind vibration response analysis
• Seismic response simulation

In practical engineering applications, SAP2000 is commonly used for:

• Long-span stadium structures
• Spatial truss structures
• High-rise steel structures
• Complex load-bearing structural systems

In some complex steel structure projects, when conventional software cannot provide sufficiently detailed analysis, engineers often use SAP2000 for supplementary finite element verification.

Its advanced analysis capabilities become especially valuable in complicated spatial structures and special loading conditions.

6. IDEA StatiCa

In the field of steel connection analysis, IDEA StatiCa has become increasingly popular among structural engineers.

Its main advantages include:

• Powerful steel connection analysis capabilities
• Extensive built-in connection libraries
• Parametric node modeling
• BIM software integration
• Compatibility with Chinese steel structure standards

In some of Henan Jingyuan’s irregular steel structure and complex node projects, steel connections often become one of the biggest challenges during detailing and fabrication.

Typical examples include:

• Irregular steel connections
• Thick plate welded joints
• Long-span connection nodes
• Complex high-strength bolted connections

These situations usually require highly detailed connection analysis and load verification.

IDEA StatiCa provides strong advantages in complex node analysis, making it increasingly popular in high-difficulty steel structure engineering projects.

7. STAAD.Pro

STAAD.Pro is one of the most widely used structural analysis software platforms in overseas engineering projects.

For companies involved in international steel structure projects, STAAD.Pro offers strong practical value.

Its features include:

• Integrated modeling, analysis, and design
• Support for multiple structural forms
• Compatibility with various material types
• Compliance with multiple international design standards

In international engineering projects, STAAD.Pro is commonly used for:

• Overseas industrial buildings
• International steel structure projects
• Multi-standard engineering analysis
• Overseas EPC projects

For steel structure companies involved in global business, familiarity with international engineering software platforms can significantly improve project coordination efficiency.

Practical Applications of Different Steel Structure Software

In real steel structure projects, different software platforms are rarely used independently. Instead, they work together throughout the entire engineering and fabrication process.

For example:

For steel fabrication companies, true project efficiency depends not only on software operation skills, but also on the ability to effectively connect structural design, detailing, and workshop manufacturing.

Conclusion

As steel structure engineering continues to move toward larger, more complex, and increasingly digitalized projects, professional engineering software has become an indispensable part of the industry.

From structural calculation and steel detailing to finite element analysis and workshop fabrication management, these software platforms continue to improve project efficiency and manufacturing precision.

As a company specializing in steel structure and space structure fabrication, Henan Jingyuan believes that software itself is only a tool. The real key to project quality still lies in engineering experience, detailing capability, and manufacturing expertise.

Only by fully understanding structural logic and fabrication processes can engineering software truly maximize its value in real-world steel structure projects.
