A METHOD FOR PREDICTING PRESTRESS LOSSES IN A PRESTRESSED CONCRETE STRUCTURE

PCI Journal, 1972
A METHOD IS PESENTED FOR PREDICTING ACTUAL PRESTRESS LOSSES IN A PRESTRESSED CONCRETE STRUCTURE. IT USES AVAILABLE INFORMATION ON CONCRETE CREEP AND SHRINKAGE AND STEEL STRESS RELAXATION, AND INCLUDES THE EFFECT OF INTERACTION OF THE VARIOUS FACTORS CONTRIBUTING TO PRESTRESS LOSS.

Partial Loss of Prestress

2018
Prestressing a concrete member effectively applies a substantial axial force to the member that is in place for its entire service life. In both pretensioned and post-tensioned methods of prestressing, this prestressing force begins to decline immediately upon its application and continues to decline throughout its service life. This reduction in force

Effect of Non-Prestressed Steel on Prestress Loss and Deflection

PCI Journal, 1977
A simple accurate method is presented for calculating prestress loss, axial strain, and curvature at a cross section of a member containing prestressed as well as nonprestressed steel. Two sets of graphs are given as design aids, and their use is demonstrated by numerical examples.

Losses in partially prestressed concrete

Canadian Journal of Civil Engineering, 1988
The calculation of prestress losses by the age-adjusted effective modulus method is analyzed and compared with the Ontario highway bridge design code predictions for partially prestressed concrete. Specifically, the effect of nonprestressed reinforcement on prestress losses is studied.

UNDERSTANDING THE LOSSES IN PRESTRESSING

PCI Journal, 1969
LOSSES THAT OCCUR IN PRESTRESSED CONCRETE AND ATTEMPTS TO PLACE THEM IN PROPER PERSPECTIVE TO EACH OTHER ARE DISCUSSED. LOSS OF PRESTRESS DUE TO RELAXATION OF STEEL, SHRINKAGE, ELASTIC DEFORMATION AND CREEP IN THE CONCRETE, ANCHORAGE SLIP AND TENDON FRICTION ARE DISCUSSED; METHODS OF EVALUATING THESE LOSSES ARE PRESENTED.

Prestress Losses in Partially Prestressed High Strength Concrete Beams

PCI Journal, 1993
The results of a comprehensive parametric study on prestress losses in prestressed and partially prestressed high strength concrete beams are reported. Attention is focused on the influence of the partial prestressing ratio (from no prestressing to full prestressing) and the compressive strength of concrete, from 6 ksi (41 MPa) up to 10 ksi (69 MPa ...

Loss of Prestress, Deflection, and Partial Prestress

1990
This chapter includes discussions of several important, frequently encountered subjects that pertain to the elastic design of simple prestressed concrete flexural members. An engineer who frequently is engaged in the design of prestressed structures will become familiar with these relationships through design experience.
