Assessing the structural performance of a reinforced concrete beam: The effects of simulated rotation angle utilizing robot structural analysis software.

This study investigates the effect of the rotation angle in relation to the horizontal plane on the structural behavior of a reinforced concrete beam. Simulations were performed utilizing Autodesk's Robot Structural Analysis software for four different angles: 0°, 5°, 10°, and 15° The main objective is to evaluate the impact of these angles on bending moment, shear force, and deflection. The findings show that as the angle increases, the bending moments and shear forces decrease while the deflections increase.•The methodology is a simulation study based on a finite element method.•Autodesk's Robot Structural Analysis Software is the main tool of this study.

Assessment of ultrasonic data of signals backscattered by mortar using the principal component analysis.

In this paper, we present the assessment of ultrasonic parameters of signals backscattered by mortar using the Principal Component Method. The measurement has been performed by the ultrasonic reflection technique using a transducer with a central frequency 0.5 MHz. The samples examined consist of specimen mortar mixtures prepared with ratio cement/sand (c/s = 0.5) and water/cement (w/c = 0.65) and studied at three temperatures 25 °C, 32 °C and 42 °C. The projection of the data showed that more than 93% of the information is retained and presented in 2D space. The correlation between Acoustic Impedance and Ultrasonic Velocity at 25 °C, 32 °C and 42 °C are 96.95%, 99.98%, and 99.98% respectively. The data are associated with the research article "Ultrasonic Characterization and Hardening of Mortar Using the Reflection Technique" (H.LOTFI and al.).
