A strut and tie model for FRCM-strengthened reinforced concrete deep beams
Wakjira, Tadesse; Ebead, Usama ( ISEC Press , 2019 , Conference Paper)Exiting literature revealed that fabric reinforced cementitious matrix (FRCM) is a promising material for the strengthening of shear deficient reinforced concrete (RC) beams. However, most of the available experimental ... -
An effective technique utilizing frcm system in strengthening rc beams in shear
Wakjira, Tadesse; Ebead, Usama ( ISEC Press , 2018 , Conference Paper)This paper presents the efficacy of a new technique of fabric reinforced cementitious matrix (FRCM) for the strengthening of shear deficient reinforced concrete (RC) beams. This technique involves embedding the FRCM ... -
Blue-collar workers' travel behavior modeling using exPlainable machine learning model: The case of Qatar
Alkhereibi, Aya; AbuZaid, Ali; Wakjira, Tadesse ( Qatar University Press , 2021 , Poster)This paper presents a novel study on the examination of explainable machine learning (ML) technique to predict the mode choice for communities with a majority of blue-collared workers. A total of 4875 trip records for 1050 ... -
Effectiveness of frcm system in strengthening rc beams in shear using hybrid nse/eb technique
Ebead, Usama; Wakjira, Tadesse ( ISEC Press , 2018 , Conference Paper)This paper presents an experimental study on the efficacy of a recently introduced hybrid "near surface embedded/ externally bonded" NSE/EB fabric reinforced cementitious matrix (FRCM). Seven medium scale RC beams, deficient ... -
Shear capacity of reinforced concrete deep beams using genetic algorithm
Wakjira, Tadesse; Ibrahim, Mohamed; Sajjad, Bilal; Ebead, Usama ( IOP Publishing Ltd , 2020 , Conference Paper)It is vital to understand the shear behaviour of reinforced concrete (RC) beams in order to avoid a catastrophic shear failure and design for ductile failure. However, due to the complexity in the shear failure mechanism ... -
Shear strengthening of RC beams with steel reinforced grout (SRG)
Wakjira, Tadesse; Ebead, Usama ( University of Cantabria - Building Technology R&D Group , 2020 , Conference Paper)Steel reinforced grout (SRG) has shown to be an efficient and cost-effective strengthening solution for reinforced concrete (RC) structures. With regard to RC beams, the experimental studies to date have focused mainly on ... -
Shear strengthening of reinforced concrete deep beams using near-surface mounted hybrid carbon/glass fibre reinforced polymer strips
Ibrahim, Mohamed; Wakjira, Tadesse; Ebead, Usama ( Elsevier , 2020 , Article)This study investigated the efficacy of near surface mounted (NSM) hybrid carbon/glass fibre reinforced polymer (FRP) strips for strengthening of shear-deficient reinforced-concrete (RC) rectangular deep beams. A specific ... -
Simplified compression field theory-based model for shear strength of fabric-reinforced cementitious matrix-strengthened reinforced concrete beams
Wakjira, Tadesse; Ebead, Usama ( American Concrete Institute , 2020 , Article)Fabric-reinforced cementitious matrix (FRCM) systems are becoming an excellent choice for the shear strengthening of reinforced concrete (RC) beams owing to their excellent structural performance and compatibility with the ...
