Wrinkles in Tensile Membrane Structures

Addressing Wrinkles in Tensile Membrane Structures: A Guide for Designers and Owners


Tensile membrane structures offer both aesthetic and functional benefits, but wrinkles in high-stress or compression areas can undermine their appeal and integrity. Small winkles and isolation is ok . This guide provides practical advice for designers and owners on understanding and addressing the causes, implications, and long-term effects of critical wrinkles at a high stress area in tensile membrane structures.

Understanding the Causes of Wrinkles

  1. Design Issues
    • Pre-Stress Calculations: Ensuring appropriate pre-stress levels is critical. Insufficient or uneven tensioning can cause wrinkles. Utilize advanced simulations to achieve accurate pre-stress calculations.
    • Patterning and Shape: Precise cutting and patterning are essential to match the intended geometry. Errors can result in excess material, leading to wrinkles.
  2. Fabrication Problems
    • Material Quality: Ensure the fabric is free from defects like inconsistencies in weave or coating, which can create weak points prone to wrinkling. Select high-quality materials from reputable suppliers.
    • Seam Construction: High-quality seams and connections are crucial for distributing tension evenly. Faulty fabrication can result in localized stress points, causing wrinkles.
  3. Installation Errors
    • Tensioning Process: Uniform tensioning during installation is vital. Inadequate or uneven tension can cause parts of the membrane to sag or wrinkle. Utilize professional installation teams trained in uniform tensioning techniques.
    • Alignment: Proper alignment with the support structure ensures even load distribution. Misalignment during installation can lead to improper tensioning and wrinkles.

Implications of Wrinkles

  1. Structural Concerns
    • Stress Concentration: Wrinkles indicate areas of non-uniform tension, leading to stress concentrations that weaken the structure.
    • Risk of Damage: Over time, stress concentrations can cause material fatigue, increasing the risk of tears or punctures.
  2. Aesthetic Impact
    • Visual Disruption: Wrinkles can significantly detract from the clean, sleek look of tensile membrane structures, affecting the building’s overall aesthetics.
    • Perceived Quality: The presence of wrinkles can suggest poor design or workmanship, impacting the perceived quality of the project.

Long-Term Effects

  1. Durability and Maintenance
    • Uneven Wear: Wrinkles can cause uneven wear, reducing the membrane’s lifespan and increasing maintenance costs.
    • Water Accumulation: Wrinkles can create pockets that trap water, leading to issues like mold growth and fabric degradation.
  2. Structural Integrity
    • Performance Reduction: Wrinkles affect load distribution, reducing the membrane’s efficiency in carrying loads.
    • Failure Risk: Prolonged stress and material fatigue from wrinkles can lead to structural failure, posing safety risks.

Improving Expertise and Workmanship

Finally wrinkles in tensile membrane structures highlight areas needing attention in design, fabrication, and installation.


Wrinkles in tensile membrane structures can indicate underlying issues that need addressing during design, fabrication, or installation. By understanding and mitigating these issues, designers and owners can enhance the aesthetic and structural integrity of their projects.
