Prestressed truss girder after 60 years

Key Points

Corrosion leads to structural failures in prestressed girders, impacting safety and longevity.
Assessment of prestressed roof girders shows a notable decline in structural integrity over 60 years.
Analysis includes lessons from various constructions in Czechoslovakia and abroad, emphasizing the need for maintenance.
Awareness of corrosion in concrete structures is essential for future constructions and restorations.

Abstract

Many concrete roof structures built in the past century are dealing with corrosion of the prestressing reinforcement. This has been the cause of several failures of prestressed roof girders in the Czech Republic and Slovakia. This article focuses on prestressed truss roof girders. We will discuss various types that were constructed in former Czechoslovakia and abroad during the past century.
