Pre-stressed concrete systems can be more vulnerable to failure than ordinary reinforced concrete due to their reliance on high tension forces and the integrity of pre-stressed tendons. Unlike conventional reinforced concrete, which distributes loads more gradually, pre-stressed concrete relies on carefully applied compressive forces to counteract tensile stresses. If these forces are disrupted due to tendon corrosion, improper tensioning, or sudden overloading the entire system can fail abruptly. Additionally, pre stressed concrete is more sensitive to cracking, as minor defects can lead to a loss of pre-stress and a rapid reduction in structural integrity. Proper design, maintenance, and quality control are essential to mitigate these risks.

Thank you DE Ed Shadoin for your educated response. I agree. Pre-stressed concrete systems are more vulnerable to sudden failure because they rely on high-tension tendons to maintain strength. If these tendons are damaged by corrosion, fire, or improper tensioning, the structure can fail abruptly. Unlike traditional reinforced concrete, which allows more gradual failure, pre-stressed systems are less forgiving. Even minor cracks can lead to a loss of pre-stress and rapid structural compromise. Proper design and maintenance are critical to ensure safety.
