Abstract

Structural analysis is used to assess the behavior of engineering structures under the application of various loads. Commonly used structural analysis methods include analytical, experimental and numerical methods. The finite element method has become very popular among engineers and researchers as it is considered to be one of the best methods for solving complex engineering problems efficiently. There are various finite element software packages such as ATENA, ABAQUS, Hypermesh, Nastran and ANSYS to solve the engineering problems. Hence, in the present study ANSYS (Analysis System), finite element software is used for solving the reinforced concrete beams. The results thus obtained are verified with the experiment carried out. The experimental work highlights the study on flexural behavior of conventional and geopolymer reinforced beams with different grades of concrete namely M-30, M-40 and M-50. The test specimens was 100 x 200 x 2000 mm reinforced beams cured at room temperature. The alkaline solution used for present study was the combination of sodium silicate and sodium hydroxide solution with the ratio 2.50. The molarity used for the preparation of geoploymer solution was 12. The beams considered for the study were designed as balanced reinforced sections with percentage of reinforcement varying in the range of 1.45, 2.10 and 2.40. It was observed that the experimental values of reinforced concrete beams were in par with the results obtained with ANSYS modeling.
