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 capacity prediction of FRP-RC beams using single and ensenble ExPlainable Machine learning models
Wakjira, Tadesse G.; Al-Hamrani, Abathar; Ebead, Usama; Alnahhal, Wael ( Elsevier , 2022 , Article)Corrosion in steel reinforcement is a central issue behind the severe deterioration of existing reinforced concrete (RC) structures.

Shear span-to-depth ratio effect on steel reinforced grout strengthened reinforced concrete beams
Wakjira, Tadesse G.; Ebead, Usama ( Elsevier , 2020 , Article)The effect of the shear span-to-depth (a/d) ratio on the shear behavior of steel reinforced grout (SRG)-strengthened reinforced concrete (RC) beams is experimentally investigated. Four critical shear spans corresponding ... -
Shear strength of recycled-aggregate concrete beams with glass-FRP stirrups
Younis, Adel; El-Sherif, Hossam Eldin; Ebead, Usama ( Elsevier , 2022 , Article)The combined use of recycled concrete aggregate (RCA) and glass fiber reinforced polymer (GFRP) reinforcement in reinforced concrete (RC) structures is deemed plausible to achieve sustainable construction. This paper aims ... -
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
