This paper presents an experimental research work to evaluate prestress losses in
pretensioned prestressed concrete. An experimental program including variables such as …

Self-centering post-tensioned (SCPT) piers are recently being focused on due to their ability
to enhance the seismic performance of bridges and their low residual drifts provided by the …

Considering the interaction between concrete shrinkage and concrete creep and between
the relaxation of prestressing steel and concrete creep in the prestressed concrete member …

Two prestressed high performance concrete (HPC) highway bridges were constructed in
Texas utilizing concrete with 56 day design strengths of up to 97 MPa (14,000 psi). The …

The effects of prestressing methods and prestress levels on the friction losses of prestressed
tendons were evaluated in this study. Two full-scale prestressed concrete girders were …

This paper deals with the optimum cost design of partially prestressed concrete I
crosssectioned beams by using Genetic Algorithms. For this purpose, the optimum cost …

A time-dependent behaviour prediction of the prestressed concrete I-girder made from high-
performance concrete (HPC) is very difficult. Overestimation or underestimation of the …

Two prestressed high performance concrete (HPC) highway bridges were constructed in
Texas utilizing concrete with 56 day design strengths of up to 97 MPa (14,000 psi). The …

BACKGROUND The methods specified to determine prestress losses by the American Asso
ciation of State Highway and Trans portation Officials (AASHTO)'and the …

The present study deals with the effects of mineral admixtures, by partial replacement of
cement, in terms of improved performance on compressive and flexural strengths and …
