Abstract

Extensive research is going on nowadays on the structural performance of. Reactive. Powder. Concrete (RPC) in.concrete equipment as an extension. In addition to the other RPC rectangular.beams (performing by means of control beams), the.study consists of 15 clearly supports RPCT beams that have been waking to failure.under 2. Pointload. Pointload. Measures for the.cracking.load, the.ultimate shear.load, mid-spandeflection, maximum have been recorded. Crack. Crack. Width, concrete strains at key sites and failure patterns. The variables in this experimental program were the volumetric ratios of steel fibers Vf. Longitudinal strengthening ratio ?w, silica.fume quality FF, shear range to efficient.depth proportion a / d, width of flange .. bf and width of flangeThickness tf. It was estimated that steel fibers increased from 1 percent to 2 percent, diagonal cracking (Pcr) from 20 to 60 percent, while the ultimate.shear.load (Pu) increased from 55.8 to 171.2 percent, similarly as.associated.to nonfibrous RPC.T-beams. Moreover, in the other.variable such as.as.?.and SF.had.lesser possessions.on.the.cracking, the rise is ultimate.loads. Growing a / d ratio from 2.5 to 3.5and 4.3withVf = 2 and 7.7%, both. Pcr decreased by 11.11 and 33.33% and Pu decreased by 41.4% and 52.3% by 41.4 respectively. Growing bf and tf demonstrated an insignificant growth in Pcr, butPu was increased by 19.2%, 48.3 and 82.03% in.evalu.with a rectangular RPC.beam consuming.b = bw.
