  author={Halit Cenan Mertol and Sami H. Rizkalla and Paul Zia and A. Mirmiran},
  journal={Pci Journal},
This paper summarizes the findings of an extensive research program that examined the shrinkage and creep behavior of high-strength concrete (HSC) up to a strength of 18 ksi (124 MPa). Creep and shrinkage strains of 60 specimens were monitored for up to 2 years. The variables considered in this research were the concrete compressive strength, specimen size, curing type, age of concrete at loading, and loading stress level. Findings indicate that the current American Association of State Highway…

Evaluation of AASHTO Provisions for Creep and Shrinkage of Prestressed UHPC Girders

The use of ultra-high performance concrete (UHPC) for pretensioned bridge girders is appealing for bridge engineers due to its superior engineering properties. Design of pretensioned UHPC girders


It is well known that concrete experiences time-dependent creep displacement when subjected to sustained compressive loads. This paper describes a so-called “creep-rupture” failure mode in which

Long‐term material and structural behavior of high‐strength concrete cantilever bridge: Results of 20 years monitoring

In 1997, the Second Stichtse Bridge was built in the Netherlands using the balanced cantilever method. The use of high‐strength concrete was proposed. At that time, the long‐term behaviour of this

Long term deformation of beams and columns of high performance concrete

The columns of a building must be stronger than the beams. The aim of this study is to obtain the cause of the long-term deformation difference by shrinkage between the beams and columns of high

Experimental Verification of the Concrete Shrinkage Strains Course According to En 1992-2 Standard

Abstract The article provides basic information about the shrinkage of concrete and discusses the major impact on the size and course of the shrinkage. There are the guidelines to estimate the

Long-term Shrinkage Empirical Model of High Performance Concrete in Humid Tropical Weather

This paper represents a long-term shrinkage empirical model of high performance concrete (HPC) with and without fly ash based on experimental research in which compressive strength was 60MPa.

Comparative Analysis of Measured and Predicted Shrinkage Strain in Concrete

Abstract The article discusses the issues related to concrete shrinkage. The basic information on the phenomenon is presented as well as the factors that determine the contraction are pointed out and

Creep at early ages of ultrahigh-strength concrete: experiment and modelling

Ultrahigh-strength concrete (UHSC) is a promising material for engineering applications, owing to the rapid increase of compressive strength at early ages. In this study, the creep behaviour of UHS...



Application of the LRFD Bridge Design Specifications to High-Strength Structural Concrete: Flexure and Compression Provisions

This report documents research performed to develop recommended revisions to the "AASHTO LRFD Bridge Design Specifications" to extend the applicability of the flexural and compression design


This report presents guidelines to help bridge designers obtain realistic estimates of prestress losses in high-strength pretensioned concrete bridge girders and thus achieve economical designs.
