Non-linear analysis of reactive powder concrete (RPC)‎ deep beams with openings strengthened by Cfrp

Abstract EN

This paper mainly uses ANSYS V.15 , the finite element analysis software, to make nonlinear analysis of reactive powder concrete deep beams .

The models simulating the test process were established, the calculation results of ANSYS are compared with the experimental results.

Data of eight RPC deep beams tested by researchers were used for comparison with ANSYS models .Furthermore three parametric studies were carried out by changing the size of opening , location of openings and CFRP systems configuration .

The comparison shows that ANSYS analysis results are similar to experimental results (the maximum difference in the ultimate load was less than 7.5 %), which indicates ANSYS analysis software can be used to simulate the mechanical property of reactive powder concrete structures.
