Finite Element Modelling of FRHP Concrete Reinforced Beam-columns Subjected to Monotonic Loading

摘要

In this Investigation finite element model was developed to evaluate the experimental results. The investigation is to be carried on the FRHPC reinforced beam-columns containing fly ash and metakaolin as mineral admixtures and with addition of Polyolefin Macro Monofilament Fibre for the production of "Polyolefin Macro Monofilament Fibre Reinforced High Performance Concrete" [PMMFRHPC]" at the various dosage of 0.1, 0.2, & 0.3 percentages by the volume fraction. Concrete mix M60 grade was designed as per ACI 211.4R-08. The Portland cement was partially replaced with mineral admixtures flyash 10% and metakaolin 10%. Experimental investigation was carried out on Mechanical properties and Flexural behavior of Fibre Reinforced High Performance under reinforced Concrete Beam-columns, and results were studied. The following procedure is used to meet this goal. First, a literature review is conducted to evaluate previous experimental and analytical procedures related to reinforced concrete components. Second, a calibration model using a commercial finite element analysis package (ANSYS) is set up and evaluates using experimental data. FRHPC reinforced beam-columns subjected to two-point loading was analyzed to failure and compared with experimental results to calibrate the parameters in ANSYS analyses. The accuracy of the finite element models is assessed by comparison with the experimental results, which are to be in good agreement/The load-deflection curves and moment-rotation curves from the finite element analysis agree well with the experimental results in the linear range, but the finite elements results are slightly stiffer than that from the experimental results. The maximum difference occurred in ultimate loads for all the cases.
