N2 - As a part of study on recycled aggregate concrete (RAC) application on structural element, experiments on simple beam using Digital Image Correlation (DIC) results and numerical study results are presented. The experimental study involves a 3000 x 150 x 250 mm3 beam with semi-cyclic loading using DIC to investigate the load vs. deflection, strain, and cracking behavior, with comparison to measurement using LVDT and cracking formation on the sample. The numerical study is done in CAST3M using Timoshenko multi-fibre beam element with Mazars and Unilateral La Borderie concrete model along with PARFAIT_UNI for the steel model, with the objective of replicating the load vs. deflection graph and strain distribution of the experiment. From the experiment, the results for midspan deflection from DIC are similar with readings from LVDT and from the strain distribution the beam experienced flexural and inclined cracking during the loading phase, while majority of flexural cracking closed during unloading phase except two locations where permanent cracking has formed at yield limit. From the numerical study, Mazars and unilateral La Borderie concrete model along with PARFAIT_UNI steel model using multi-fibre Timoshenko beam element could approach the load vs. deflection graph of the experiment using monotonic loading. On the other hand, the numerical model shows less residual deformation and higher load capacity during loading-unloading cycle using semi-cyclic loading. The Numerical model strain distribution obtained using unilateral La Borderie concrete models cannot show specific location where cracking happens, but it can show the area where cracking will likely be distributed.
