Shear Behaviour Analysis of Reinforced Concrete Beam Using Non-Linear Finite Element Simulation

Abstract

This paper investigates shear behaviour of reinforced concrete using multi-surface plasticity model. This analysis uses nonlinear finite element simulation using 3D-NLFEA finite element package. The experimental data adopted from the results of experimental test on eighteen beams where nine beams carried out by Bresler and Scordelis in 1963 and similar nine beams carried out by Vecchio and Shim in 2004. The constitutive model for the concrete material which used in this simulation is based on the plasticity-fracture model and considered the tension stiffening effect for the concrete. The result of the numerical simulation latter compared with the experimental test including load-deflection response, cracking pattern, and failure mode. Based on the analysis result, it was found that the load-deflection response shows slightly higher. For Bresler and Scordelis beams test, the mean ratio of prediction peak load to actual peak load from the experimental result and a coefficient of variation of 1.00 and 7.42%, respectively and for Vecchio and Shim beams test, the mean ratio of prediction peak load to actual peak load from the experimental result and a coefficient of variation of 0.92 and 4.04%, respectively. However, the cracking pattern and failure mode of the beam shows good result which is in compliance with the experimental test.

Electrodeposition of CU2O Films at Room Temperature for Methylene Blue Photodegradation

“…Furthermore, electrodeposition allows film formation directly on the substrates and supports the integration of the prepared film within the device [2,3]. Previous studies on the electrodeposition of Cu 2 O [4][5][6][7], which is known as a robust, facile, and scalable technique, have shown that surface features and microstructure the deposit be tuned by adjusting reaction conditions [8]. These copper oxide compounds are considered as a promising low-cost semiconductor material for photocatalyst application.…”
