Analysis Data of investigating the fracture behavior of structural concrete shear key in prefabricated walls by discrete modeling

This dataset contains the output of the simulations of shear key connections in prefabricated concrete walls using a discrete model named Rigid Body Coupled Springs (RBCS). The shear key connections with different design configurations are modeled. The raw data files are in GMSH mesh format (see https://gmsh.info/) and contain various displacement and stress data at every time step. The prescribed displacement increment of 0.025mm is applied to the top bearing at every analysis step.
Since the main interest in this study is the initial stages of the deformation, the employed RBCS approach uses the condition of infinitesimal deformations and rotations. In addition, a simple interface between the prefabricated parts and the cast-in-situ connection is used in the model. These assumptions limit the analysis outcome to the early steps even though later stages are still included in the raw data file.
The outcomes show that the RBCS can demonstrate the failure mode of shear keys. With the shallow shear keys (D10) a complete fracture of the keys is not observed while the deep shear keys (D20) demonstrate a different fracture pattern with complete shearing of one shear key at each end of the cast concrete.
