Fracture-Based Method to Determine Flexural Capacity of Concrete Beams on Soil

摘要: ABSTRACT A method to predict the fracture response of concrete beams utilizing cohesive crack elements was expanded from a three-point bending beam on soil boundary condition. The simulations were compared with monotonic and tests, verifying bilinear softening curve defined by concrete's tensile strength properties can effectively flexural capacity post-peak behavior both specimen configurations. Vertical horizontal springs idealized support beams. Whether linear or nonlinear elastic had limited effect peak load soil. At pre-peak levels, two configurations similar stress patterns propagation levels in spite different conditions. simplicity accuracy under conditions offers promising approach that be extended predi...
