Three-dimensional cohesive crack model prediction of the flexural capacity of concrete slabs on soil

摘要: Abstract A three-dimensional approach to discretely account for crack initiation, growth, and determination of the flexural load capacity concrete slabs on an elastic foundation under mode I loading is proposed. The finite element model incorporated cohesive elements along a pre-defined path in slab. bilinear softening was used describe stress-crack opening relationship plain defined solely measured strength fracture properties. proposed method predicted slab’s as compared large-scale experimental slab results several geometries notch configurations. also provided insight into stress concentration areas propagation positions at different levels.
