Long-Term Prestress Loss Calculation Considering the Interaction of Concrete Shrinkage, Concrete Creep, and Stress Relaxation

open access: yesMaterials, 2023
In order to accurately calculate the long-term prestress losses of prestressed tendons, a time-varying model of long-term prestress loss considering the interaction between concrete shrinkage, creep, and the stress relaxation of prestressed tendons was ...

Effect of prestress on phononic band gaps induced by inertial amplification [PDF]

open access: yes, 2021
Phononic crystals and elastic metamaterials have recently received significant attention due to their potential for unconventional wave control. Despite this interest, one outstanding issue is that their band diagram is typically fixed once the structure

COMPARING THE RIGIDITY OF THE PRESTRESSED AND NON-PRESTRESSED FOUNDATION [PDF]

open access: yesJurnal Teknologi, 2016
If compared with reinforced concrete, the prestressed concrete is able to resist higher loads before cracks develop. As cracks reduce considerably rigidity of the element, the prestressed element can be regarded as rather rigid. The article compares the rigidity of the prestressed and non-prestressed foundations in two axes.
