Abstract

Flat slab structures situated in seismic zones, the moments transferring from slab to column through shear increases furthermore and becoming more tendency to punching shear failure during earthquakes. There are many ways to increase the punching shear strength of concrete slabs. Few techniques are shear reinforcement system, flat slab with externally bonded CFRP at corner columns, using post-installed steel bolts using carbon fiber reinforced polymer laminates in slabs, using glass fiber reinforced polymer laminates in slabs. A nonlinear static analysis of flat slab is done using ANSYS workbench to study punching shear strengthening techniques. Deflection values of various strengthening techniques were found out and compared with the limit. In this project, it is found that strengthening using carbon fiber reinforced polymer laminates and shear reinforcement are effective punching. Shear strengthening techniques.
