Abstract:
Presents the results from a study of modeling concrete in the postcracking range using a three dimensional finite element analysis. The analytical work was based on an experimental study of concrete foundations which were loaded through bearing plates. The discrete cracking model was used, resulting in cracking which closely followed that in the tests. Comparisons have been made for different meshes, variable concrete material properties, and variable foundation dimensions. Failure occurred when the concrete foundation broke into segments, with a resulting loss in load-carrying capacity. The approach used is conceptually straightforward, lying between three-dimensional elastic analyses used in the past for concrete foundations and highly rigorous theoretical ones which have been used only for very limited applications.
