Tag: Incorrect execution of planned design Reasons for failure of prestressing steel

Premature failure of prestressing steel in prestressed concrete structures is usually induced by corrosion. The most obvious type of failure occurs when high-strength steel fails because, in areas of corrosion pitting, its notched bar tensile strength is exceeded. In such a case, the failure is brittle in character (Section 6.4.1). The effect of local corrosion on the strength and deformation
