Which risk increases when a post-tensioned concrete beam experiences sudden tendon rupture during construction?

💡 Explanation

When a tendon ruptures suddenly, energy release accelerates stress concentrations around anchorages because the force distribution changes abruptly. Therefore concrete spalling near anchorages results, rather than excessive deflection, chloride ingress or reduced fire resistance which are driven by other environmental or design factors.
