Numerical study of bond stress-slip relationship in large scale reactive powder concrete beams

Abstract EN

the reactive powder concrete (RPC) represents one of the ultra-high performance concrete types that recently used in public works and in the presence of several attempts that aims to examine the behavior of RPC, this work aims to theoretically study the bond stress between RPC and steel bars and the corresponding slip for large reactive powder concrete beams by using finite element models done by ANSYS 16.1 software.

Where, these numerical models were verified through several comparisons between their results, and the experimental one from previous work, in which good agreement were achieved.

The effects of several parameters on the bond stress were studied, the parameters include concrete compressive strength, and steel fibers content, bar diameter, length of the developed bar and concrete cover thickness
