Abstract:
In some cases, because of the need for installations, creating cutouts in the existing RC slabs will be necessary whereas these cutouts can cause weakness in the strength and stiffness of the slabs. Nowadays, expanding the use of FRP materials can provide the possibility of easier strengthening of such slabs. There are various methods for strengthening with FRP including Externally Bonded FRP sheets, Near Surface Mounted FRP rebars, and Mechanically Fastened FRP sheets. To select the most appropriate techniques for strengthening RC slabs with cutouts, it is essential to know different structural performance of these strengthened slabs. This research tends to model one and two-way spanning RC slabs with rectangular cutouts that strengthened with different techniques by finite element method. After verification with existing test results, it also compares and analyzes structural performance of strengthened RC slabs such as load bearing capacity and maximum deflection at ultimate load. Then, if possible, it will be done for other forms of cutouts. Moreover, the possible effects on the functioning of the various forms of FRP strengthening techniques will be analyzed
