The main objective of this research is to present a study into the time dependent behaviour of plain concrete and reinforced concrete members subjected to pure torsional loading.
In this research project, the time dependent deformation of the plain concrete and for both uncracked and cracked reinforced concrete have been investigated. Three major elements are included in this research: 1) The analytical investigation, 2) The experimental study and 3) The computer simulations.
Analytical models for the time dependent effect on reinforced concrete members under pure torque is developed for both cases of uncracked and cracked concrete with aided of the experimental investigation and previous study on uniaxial load. While short tests for determining the strength and elastic behaviour and plain and reinforced concrete are required for supporting the information of basic material properties. According to the results of the experiment, a mathematical model is developed for predicting the time dependent behaviour.
At the same time, the developed analytical predictions are compared with measurements from test data and computer modeling so that the validation of the analytical models can be verified.
The analytical model and analysis show good correlation with experimental results obtained in this study.
