Nonlinear analysis of RHA concrete beam using ANSYS
So rice husk can be used as supplemental cement material due to its pozzolanic effect. Rice husk as agricultural waste if used properly not only reduces environmental problems but also reduces carbon dioxide emissions into the atmosphere by reducing cement production. Current experimental work using ash of rice husk (RHA) being material of supplementation has shown good enhancement in the properties of the RC beams. This paper presents results obtained from the analytical model of the RHA concrete beams. The study included developing an analytical model using finite element method ANSYS R15.0 software. For validation the results, the analytical model was compared with the experimental work using similar properties. By using four point loading flexural test, ten simply supported RC beams were tested containing various rice husk ash percentages. Results showed that all RHA concrete beams of the analytical model failed by flexural similarly to the experimental work. The average of FEM to experimental ratio (for the ten models) for ultimate load was 91.173%, while for maximum deflection was 93.055 %. This indicates that the agreement between finite element results and experimental results are excellent. Also, the crack pattern, failure mode and the load-deflection curve from the analytical model related to the experimental works show good agreement.
