Criteria for Rational Prediction of Creep and Shrinkage of Concrete

The paper discusses the problem of formulation and evaluation of a prediction model for creep and shrinkage of concrete. Verification by comparisons to a few subjectively selected data sets is no longer justifiable because computers have made statistical comparisons to the complete existing data bank easy. However, statistics based on the data bank are insufficient. There are three further crit...

Prediction of concrete creep and shrinkage: past, present and future

The first part of the paper summarizes various aspects of the prediction of concrete creep and shrinkage to be discussed in the conference lecture. They include the theories of physical mechanism, prediction models, constitutive equations, computational approaches, probabilistic aspects, and research directions. The second part then presents two new prediction models. One of them deals with the...

Damage in Prestressed Concrete Structures due to Creep and Shrinkage of Concrete

The theory of concrete creep and shrinkage has not been regarded as part of what has been understood as damage mechanics. However, these inelastic phenomena do result in significant damages to structures, including not only distributed cracking, which is damage in classical sense, but also damage in the form of excessive deflection which puts the structure out of service. It is for this reason ...

Sampling analysis of concrete structures for creep and shrinkage with correlated random material parameters

The latin hypercube sampling method, which represents the most efficient way to determine the statistics of the creep and shrinkage response of structures, has previously been developed and used under the assumption that the random parameters of the creep and shrinkage prediction model are mutually independent. In reality they are correlated. On the basis of existing data, this paper establishe...

CREEP RATE IN CONCRETE 337 Discussion on the Proposed Creep Law

Despite decades of intensive research, an entirely satisfactory constitutive relation for creep in concrete is still unavailable, even for working stress levels [I]. The rate-type creep laws with internal variables [2], although rather effective for numerical creep analysis of large structural systems, seem to be incapable of describing the aging phenomena without at least partially violating s...
