Modeling and Analysis of Prestressed Lightweight Aggregate Concrete Beams - Time Dependent Deformations
Original language description
Three beams were produced from light weight aggregate concrete. After seven days of the concreting the samples were prestressed, and finally loaded after 28 days by loading blocks. A computer model was created and the results from this model and experiments were compared. To obtain the computer model as close as possible to the reality, all the material properties (modulus of elasticity, ultimate strength, etc.) used in the computer model were obtained from the experimental data. The values obtained from the measurements were calculated according to the Czech National Standards. The deformations are measured using the strain gauge technique and the deflections with dial gauges. The computer model uses a linear geometric and linear elastic material model, the generalpurpose finite element code ANSYS was used.
