Novel method for identifying residual prestress force in simply supported concrete girder-bridges
Advances in Structural Engineering, 2021 Testing methods are required for estimating prestress losses in Prestressed Concrete (PC) girder-bridges. They mainly include destructive approaches which cause significant damages. Conversely, dynamic nondestructive methods are unsuitable.

Analysis of Prestressing in Precast Prestressed Concrete Beams
Civil and Environmental Engineering, 2021 Abstract Knowledge of prestressing force’s value is in the case of prestressed concrete structure the most important basis for defining load-carrying capacity and remaining service life. Numbers of prestressed concrete structures are about to reach their limit of service life and they are exhibiting signs of deterioration due to the ...

State-of-the-Art Review on Determining Prestress Losses in Prestressed Concrete Girders
Applied Sciences, 2020 Prestressing methods were used to realize long-span bridges in the last few decades. For their predictive maintenance, devices and dynamic nondestructive procedures for identifying prestress losses were mainly developed since serviceability and safety of

Tailoring of residual stresses by specific use of defined prestress during laser shock peening
, 2021 The aim of the present study is to tailor laser shock peening-induced residual stresses by applying defined prestress. For this purpose, elastic prestress is introduced during laser shock peening application and subsequently released.
