FLEXURAL BEHAVIOR OF RC BEAMS CONTAINS RUBBERIZED PIECES AND STRENGTHENED WITH CFRP SHEETS

When rubberized, concrete beams lose some of their flexural strength. Conversely, strengthening accounts for a sizeable portion the structural applications external carbon fiber reinforced polymers (CFRP) sheets that strengthen beams. In this study, externally bonded were used to compensate strength loss brought on by using rubberized in constructing The study's split into two groups, each with three first group, waste tire rubber (WTR) replaced (5 and 10) % fine coarse aggregate, respectively. reference group is second typical concrete-mixture without rubber. Each beam measured (2.1 m ×0.3m × 0.2m) has same tensile, compression, shear reinforcement. Every contained any reinforcement, single layer, double layers sheet, where soffit was strengthened. ABAQUS' finite element analysis software represent third layer numerically. mechanical properties groups have been tested; additionally, response examined monotonic two-point loading. outcomes denote one sheet increases crack load (FCL) failure (FL) (8.57 17.64) (17.14 34.27) %, deflection (FCD) also increased (58.64) (78.19) while (FD) decreased (13.25) (5.42)
