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.

1

Project Review

We review structural drawings, specifications, member sizes, connection responsibilities and required deliverables.

2

Load Review

Member reactions, shear, axial forces, moments and applicable load combinations are reviewed.

3

Connection Development

Suitable connection configurations are selected based on forces, geometry and fabrication requirements.

4

Engineering Calculations

Bolts, welds, plates and supporting members are evaluated against applicable design requirements.

5

Detailing Coordination

Connection information is coordinated with the steel detailing team for implementation in models and shop drawings.

6

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.

Connection Design Deliverables

Deliverables can be structured to suit the client's engineering, fabrication and project-management workflow.

  • Connection design calculations
  • Connection calculation packages
  • Connection sketches
  • Connection mark references
  • Connection schedules
  • Load and reaction summaries
  • Design assumptions
  • Connection summary sheets
  • Calculation reports
  • Design notes
  • Connection mapping information
  • Detailing coordination information
  • Revised calculations following design changes
  • Project-specific engineering documentation

  • Detect connection clashes
  • Confirm installation clearances
  • Resolve complex load-transfer conditions
  • Reduce late-stage connection changes
  • Improve detailing consistency
  • Reduce avoidable RFIs
  • Support accurate fabrication drawings
  • Improve engineer-detailer coordination
  • Maintain project schedules

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.

Outsourcing is ideal when in-house teams are capacity-constrained, require stamped calculations, or need complex seismic/moment connection expertise.

Direct integration between modeling software like Tekla Structures and engineering tools ensures design intent aligns with fabrication drawings.
