A case study of T- beams with hybrid section shear characteristics of
reactive powder concrete
Abstract
Extensive research is going on nowadays on the structural performance of
Reactive Powder Concrete (RPC) as an extension of the recent advances in
concrete knowledge. Thesis offerings a direction to examine the shear
behavior as well as determining the cracking and ultimate shear
capacities of RPC T-beams. The mechanical features of this construction
material and the approach to revise the reactive powder shear hybrid
segment T- Beams are cast-off in this motion are investigated in this
experimental study. In order to evaluate the effects of steel fiber
volumetric ratio, silica fume ratio, tensile steel ratio, hybrid section
on Reactive powder T-beam flexural efficiency, the experimental program
involved testing four beams. The goal of the research was to figure out
the load-deflection behavior, letdown mode, strain supply over the depth
of the beams, and failure crack pattern. In examining the mechanical
properties of Reactive powder mixtures, the volumetric ratio of steel
fibers and the silica fume ratio were also studied. Furthermore, a
hybrid beams study revealed that the use of reactive powder web and
normal concrete in flange effectively improves the performance of
T-beams when compared to normal concrete T-beams by 12%, and hybrid
beams have also revealed that the use of reactive powder flange and
normal concrete in web effectively improves the show of T-beams when
compared to regular concrete T-beams by 28%
