Custom Joist Profiles for Irregular Architectural Spans

Bridging the gap between bold architectural vision and structural feasibility through precision-engineered joist design and detailing.

Custom Joist Profiles for Irregular Architectural Spans

The Challenge of Irregular Spans in Modern Architecture

Today's bold architectural designs often feature sweeping, irregular spans that push the boundaries of traditional structural systems. These innovative spaces create unique challenges for structural engineers and detailers.

When standard joists won't do the job, custom-designed solutions become necessary to support these distinctive architectural features while maintaining both safety and aesthetics.

The Evolution of Joist Design

Traditional Joists
Standardized K-series and LH-series joists with uniform
depths and straight profiles dominated construction for decades.
Special Profile Joists
Introduction of bowstring, arched, and pitched profiles to accommodate
more varied architectural needs.
Custom Solutions
Today's fully customized joists with irregular geometries,
variable depths, and complex load paths to meet unique design requirements.

At Consac, we've witnessed this evolution firsthand, adapting our detailing expertise to embrace these increasingly complex structural challenges.

Detailing Considerations for Irregular Joists

Critical Detailing Factors

  • Connection complexity at varying angles

  • Precise member sizing for varied load paths

  • Fabrication tolerance management

  • Clear communication of complex geometry

  • Coordination with other building systems

Proper detailing is essential for translating innovative designs into buildable structures. The difference between success and costly rework often lies in the quality of joist detailing.

Benefits of Custom Joist Profiles

Architectural Freedom
Custom joists allow architects to realize their vision without compromising on structural integrity, supporting curved rooflines, dramatic cantilevers, and asymmetrical spans.
Structural Efficiency
Tailored joist profiles can be optimized for specific load paths, potentially reducing material usage while maintaining or improving structural performance.
Space Optimization
Variable depth joists can accommodate mechanical systems and other building elements where needed, maximizing usable interior space.

The Detailing Process

Architectural Review
Analyzing the architectural intent and identifying structural requirements for the irregular spans.
Structural Design
Engineering the joist profile to meet load requirements while conforming to the required geometry.
Detailed Modeling
Creating precise 3D models and shop drawings that specify every component and connection.
Coordination
Working with fabricators and installers to ensure the custom joists can be built and erected efficiently.
