DOI: 10.1016/j.conbuildmat.2020.119573

Abstract: Abstract During the last 10 years, the used of distinct mineral, plasticizing additives, and aggregates into self-compact concrete (SCC) has been widely investigated. A self-compact lightweight concrete (SCLC) is produced using porous aggregates, while a self-compact… read more here.

Published in 2017 at "Engineering Structures"

DOI: 10.1016/j.engstruct.2017.01.045

Abstract: Abstract The recent experimental results and proposed strut-and-tie model (STM) for deep beams reinforced entirely with glass-fiber-reinforced polymer (GFRP) bars have suggested that a comprehensive examination is required to improve the strut efficiency factor and… read more here.

Published in 2021 at "European Journal of Environmental and Civil Engineering"

DOI: 10.1080/19648189.2021.1885500

Abstract: In this paper, an empirical model for a strut efficiency factor (βs) is proposed and introduced in to the softened strut and tie model to predict the ultimate shear strength and the corresponding u... read more here.
