A research study was undertaken to assess performance of flat plate systems constructed with slab shear reinforcement under dynamic loads. The research program consisted of shake table tests and accompanying analytical studies of two, approximately one-third scale, two-story, two-bay, slab-column frames. One specimen was constructed with reinforced concrete (RC) slab, whereas the other specimen...

Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in shear, punching around the load or a mixed mode between them. Until now, most publications presented recommendations to assess capacity considering only mechanism. This study proposed developing both and of such slabs. Different codes practice were addressed, including cur...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

This study conducts numerical analyses on a newly developed double-layer steel-lightweight high ductility cement composite (LHDCC)-steel sandwich panel under concentrated punching load. Energy absorption ability serves as an important criterion in evaluating the performance of protective structures. One critical factor related to energy is stiffness or deformation capacity structure. The presen...

The ordinary (OSC) and geosynthetic-encased stone column (ESC) with different bearing strata significantly influenced its behavior. paper established seven models for studying the behavior of floating columns using finite difference method (FDM). effect geogrid length on load-settlement behavior, bulging deformation, failure mode, load transfer coefficient were also analyzed based proposal mode...

Abstract On June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered sudden partial collapse. This study analyzed the overall performance and key components of collapsed based on design codes (ACI-318 GB 50010). Punching shear post-punching performances typical slab-column joints are also studied through refined finite element analysis. The collapse proce...
