Flat slabs are less labour intensive, simplify the installation of services and can accommodate more floors within restricted heights. However, the span influencing their design is the longest and they require more steel compared to two-way slabs. Other drawbacks of flat slabs are vulnerability to punching shear failure and higher deflections. To avoid punching shear failure drop panels, column...

This paper is concerned with the modelling of punching shear failure at edge columns flat slabs without reinforcement. Punching much less researched than interior despite typical buildings having more columns. The uses nonlinear finite element analysis (NLFEA) to study influence on resistance parameters including column aspect ratio and loading eccentricity. NLFEA carried out using both 3D soli...

Abstract The possibility of the occurrence a second punching shear failure and Progressive Collapse after had occurred in one flat slab column connection is investigated two building structures, using Eberick SAP2000 softwares Yield Line Method, codes ACI318:2019, EUROCODE2:2004 NBR6118:2014. It shown that connections should be designed detailed to prevent Integrity Reinforcement always present...

This paper deals with behavior and capacity of punching shear force for flat slabs produced from steel fiber reinforced self compacting concrete (SFRSCC) by application nonlinear finite element method. Nonlinear finite element analysis on nine slab specimens was achieved by using ANSYS software. A general description of the finite element method, theoretical modeling of concrete and reinforceme...

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...

Adiabatic shear localization is a catastrophic failure mechanism which can occur in ductile metals under high strain rate loading. This mechanism is driven by a thermal instability process in which rapid temperature rise due to plastic work couples with thermal softening to cause uniform deformation to collapse into narrow bands of intense shear within which material ductility is exhausted. Adi...
