Peridynamic modeling of prefabricated beams post‐cast with steelfiber reinforced high‐strength concrete

For connecting precast concrete members in prefabricated structures, steel fiber reinforced high‐strength concrete (HSFRC) shows greater bearing capacity and better durability than normal reinforced concrete. When these structures are continuously loaded, multiply micro and macro cracks will appear. The modeling of this process is challenging because the conventional finite element modeling commonly encounters numerical problems such as stress locking and overestimations of the damaging zones. On the other hand, the novel peridynamics‐based theory models the continuous and discontinuous processes in the same framework, showing robustness. In this work, based on the recently presented micropolar peridynamics with shear deformability, a numerical tool with implicit iteration scheme for quasi‐static loading condition is built. With the proposed numerical tool, the damage processes of prefabricated beam post‐cast with HSFRC are simulated. The interaction between precast, post‐cast concrete, and rebars are taken into consideration. For validations, the numerically obtained results are compared with the experimental results, indicating that this tool can provide agreeable crack patterns, initial cracking loads, and yield loads of the beams.
