Numerical and Experimental Behavior Analysis of Slabs Strengthened Using Steel Plates and Slurry-Infiltrated Mat Concrete (SIMCON) Laminates

This study has two main aims; firstly, investigating the behavior of slabs that are strengthened with different types reinforcements and Slurry-Infiltrated Mat Concrete (SIMCON) laminates, having dimensions thicknesses subjected to static dynamic (impact) loads. Secondly, development a non-linear finite element (FE) model simulate tested utilizing ABAQUS/Standard package. The modeling NSC either SIMCON or steel plates involves using three-dimensional solid elements partially integrated concretes 8-node brick (C3D8R). results experimental numerical investigations compared examine whether slab is sufficient. comparison includes type, material characteristics, real constants, convergence study. predicted ultimate load-carrying capacity versus vertical deformation response lab correspond it, as obtained via FE analysis all slabs. In addition, specimens were ones laminates. have led number significant observations. Considering punching shear strength, it was found strengthening in increased slab’s outperformed steel-strengthened As for plate stiffness, SIMCON-strengthened presented higher stiffness rates than slabs, extent even 20 mm plate-strengthened any thickness dimensions. axial load-displacement relationships indicate models show stiffer when relationships. significantly affects capacity, increases increase thickness. Likewise, from gives capacity. Finally, since yield line analyses these match closely, this method considered be suitable practical use determining strength plated Therefore, conclusion drawn proposed can sufficiently used evaluating responses cyclic impact load.
