Engineering Design of Strut-Waler Connections for Excavation Support Systems
Support-of-excavation systems frequently rely on struts and walers to resist earth pressures and maintain the stability of excavation walls during construction.
While the struts and walers themselves are critical structural elements, the connections between these components are often among the most heavily loaded and technically demanding parts of the system.
Sepco Consulting Engineers provides strut-waler connection design services throughout Ontario. We prepare structural calculations, connection details, and stamped engineering documentation for temporary excavation support systems used on commercial, industrial, infrastructure, and institutional projects.
What Is a Strut-Waler Connection?
In a typical support-of-excavation system, walers distribute earth pressures along the excavation wall while struts transfer those forces across the excavation.
The connection between the strut and waler must safely transfer significant axial forces while accommodating construction tolerances, erection requirements, and project-specific loading conditions.
Connection design often requires detailed evaluation of:
- Axial compression forces
- Connection eccentricities
- Local plate stresses
- Weld design
- Bolt design
- Bearing conditions
- Structural stability
- Fabrication constraints
Proper connection design is essential to the overall performance of the support system.
