Effect of Confinement on Creep Behavior of EPS Geofoam

With different types of applications involving submergence and higher surcharge loads, creep deformations under confining pressures have been occurring. A series of creep tests were performed on different densities of EPS geofoam with and without confining pressures.

Creep-Effect on Mechanical Behavior of Concrete Confined by

In order to investigate this creep-effect, an experiment on 8 concrete cylindrical columns confined by fiber-reinforced polymer (FRP) is carried out. Based on the theory of plasticity for concrete, a constitutive model that takes into account the effect of creep on mechanical behavior of concrete confined by FRP is presented.

Fiber Reinforced Concrete - Types, Properties and Advantages

1. Steel Fiber Reinforced Concrete. A no of steel fiber types are available as reinforcement. Round steel fiber the commonly used type are produced by cutting round wire in to short length. The typical diameter lies in the range of 0.25 to 0.75mm. Steel fibers having a rectangular c/s are produced by silting the sheets about 0.25mm thick.

Creep of Cracked Fiber Reinforced Concrete | ASU Digital

However with the advent of using fiber reinforced concrete, more and more applications where concrete is expected to carry tensile loads due to incorporation of fibers is gaining popularity. While the creep behavior of concrete in tension is important, the main case of the study is what happened when the concrete that is cr acked in service is subjected to sustained loads causing creep.
