Relative Study of Nonlinear Analysis for Torsional Strengthened RC Beams with Web Opening using CFRP and Steel Plates
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 1
Abstract
This paper displays the numerical study on fortifying reinforced concrete (RC) beams with opening exposed to unadulterated torsion. The finite elements implemented by ANSYS-2013 are used for this study. For the purpose of confirmation of the finite element model established, the numerical study is first carried out on the RC beam fortifying by external bonded-carbon fiber reinforced polymers (EB-CFRP) that were experimentally tested and described in the literature. Then the study has been stretched for the same RC beams fortifying with steel plates. The major parameter involved in this study is the fortifying effect of different schemes of steel plates and the plate’s thickness on the behavior of RC beams with opening underneath torsion. The present study reveals that the finite element models can ascertain the structural behavior of the tested beams and can be an excellent alternative of damaging laboratory tests with acceptable results, and the steel plates are more effective in strengthening the RC beams compared to the strengthening with (CFRP) for some schemes. Also results have been compared with the design methodologies of some international codes and analytical procedure produced by previous researchers. Finally, a simple suggested equation is produced to inference the torsional moment capacity of a fortifying RC beam with opening. The proposed condition affirms the precision and viability of the finite element results.
