Post Tension Cable Failure Analysis

In 2025 GES Tech Group was retained by a general contractor to evaluate the causes of post tensioned cable failures leading to a blowout.  GES reviewed all relevant documents and evidence and performed detailed non-linear FEA modeling of the anchorage geometry.  Concrete quality, a major concern, was eventually ruled out as a contributing cause.  It was finally concluded that the failure was caused by specific details at the cable anchorages.  The conditions that led to failure were corrected for future pours.
