CONNECTION DESIGN
Structural Steel Connection Design Services
A reliable structural steel system depends not only on the design of beams, columns and braces, but also on how effectively those members are connected.
Adept Engineering Solutions provides comprehensive structural steel connection design services for steel fabricators, structural engineers, contractors, EPC companies and construction teams across the USA and global markets.
Our connection engineering team develops connections that satisfy structural design requirements while considering fabrication, erection, constructability, material efficiency and detailing requirements.
From standard shear connections to complex moment, bracing, splice, base plate and industrial steel connections, our objective is to provide practical engineering solutions that can be efficiently incorporated into fabrication drawings.

Our Connection Design Process
Our workflow integrates engineering, detailing and project coordination to support efficient fabrication.
Project Review
We review structural drawings, specifications, member sizes, connection responsibilities and required deliverables.
Load Review
Member reactions, shear, axial forces, moments and applicable load combinations are reviewed.
Connection Development
Suitable connection configurations are selected based on forces, geometry and fabrication requirements.
Engineering Calculations
Bolts, welds, plates and supporting members are evaluated against applicable design requirements.
Detailing Coordination
Connection information is coordinated with the steel detailing team for implementation in models and shop drawings.
QA/QC & Submission
Calculations and engineering deliverables undergo internal review before final submission.
Connection Design Codes & Standards
Designs are developed according to the codes, standards, specifications and editions identified in the project documents.
Connection Design Integrated with Steel Detailing
One of Adept Engineering's key strengths is the ability to coordinate structural connection engineering and steel detailing within an integrated workflow.
Instead of treating engineering and detailing as completely separate activities, our teams coordinate connection requirements throughout project development.
Engineering Design → Connection Calculations → 3D Modeling → Shop Drawings → Fabrication → Erection
Depending on project requirements, our workflow can involve IDEA StatiCa, RAM Connection, GIZA, Tekla Structures, SDS2, Advance Steel, STAAD.Pro outputs and engineering calculation tools.

SHAQ
How does optimized connection design reduce steel tonnage and project cost?
Engineered connection optimization reduces excessive plate thickness, bolt overdesign, and weld volume while maintaining structural integrity under AISC load combinations.
When should fabricators outsource connection design instead of handling it in-house?
Outsourcing is ideal when in-house teams are capacity-constrained, require stamped calculations, or need complex seismic/moment connection expertise.
How does integration between detailing and connection design prevent RFI cycles?
Direct integration between modeling software like Tekla Structures and engineering tools ensures design intent aligns with fabrication drawings.
