Title: Strength Degradation of AR-Glass Filaments Due to Cyclic Tensile Loading
Author(s): B.-G. Kang, J. Hannawald and W. Brameshuber
Publication: Special Publication
Appears on pages(s): 73-96
Keywords: cyclic loading; filament tensile test; hybrid optimization; inverse parameter determination; simulation; strength degradation model; textile-reinforced concrete
Abstract:The tensile load carrying behavior under cyclic loading of filaments made of alkali-resistant glass, which is the basic component of the textile reinforcement used for textile reinforced concrete, has been analyzed. Therefore, tensile tests under cyclic loading at four different stress levels were carried out. A damage accumulation, which led in some cases to a failure of the specimens during the cyclic loading, could be observed. This motivated to introduce a strength degradation model. A calibration of the model parameters on the experimental data was performed using an optimization method. A statistical analysis was carried out beforehand, to estimate the initial tensile strengths of the specimens, which were needed for the calibration.
