Abstract: The paper introduces the experimental program of investigation on the performance of RC beams strengthened with Ultra-High-Molecular-Weight Polyethylene (UHMWPE) fabric. A research program aims at developing 3D UHMWPE textile fabric to improve the structural performance of RC members. A total of six of specimens is constructed and experimentally investigated through static tests in order to assess the structural behavior of the RC beams strengthened by 3D UHMWPE textile fabric. The first set of specimens was a normal beam without any retrofit. The second set of specimens was strengthened by 3D UHMWPE textile fabric. Testing data were analyzed to investigate the performance of the specimens retrofitted or strengthened with UHMWPE fiber compared to the non-retrofitted RC beam responses.

Abstract: The objective of this study is to evaluate the accuracy of CFD (Computational Fluid Dynamics) simulations for airflows driven by buoyancy in heated real scale rooms. In addition, this study is focusing on the influence of angular discretization used for thermal radiation computations in CFD modeling. The numerical results are compared with experimental data from the literature, based on investigations dealing with thermal coupling “room-electric heat sources”, using full scale test cells. The results show that there is no sensitivity of radiative heat flux to the walls of the room to angular discretization used in the radiation model. This means that for simple geometries, minimum angular discretization can be used for the radiation model in CFD simulations, leading to important savings in CPU (Central Processing Unit) time. Nevertheless, this deduction must be checked by further work for other configurations.
