Rubberized concrete exhibits enhanced toughness and sustainability but suffers from reduced mechanical strength, limiting its applications. This study the compressive strength of rubberized using hybrid steel/glass fibers. The results showed a positive synergy between fibers, with improvements in elastic modulus, Poisson’s ratio, peak strain, by 16.1%, 19.4%, 32.0%, 63.4%, 101.7%, respectively, at fiber content 0.8% (steel 0.6% glass 0.2%). A well-fitting stress–strain model was adopted for future constitutive simulations. advances understanding fibers under axial compression promotes application structural engineering.

Abstract This study investigates the behavior of rubberized high‐strength reinforced concrete (RHSRC) columns, including polypropylene (PP) fibers, under eccentric loads. Five distinct mixtures were formulated, wherein natural fine aggregate (NFA) was substituted with crumb rubber (CR) at varying replacement volumes 0%, 10%, and 20% for initial three mixtures, 10% in conjunction PP fibers subsequent two mixtures. Fifteen columns fabricated (three from each mixture) subjected to monotonic loading eccentricity ratios e / t = 0.25, 0.5, 0.75. The results demonstrated that incorporation CR adversely impacts load‐bearing capacity stiffness examined columns. mitigated improved these effects. Consequently, a blend may be suitable option diverse structural applications. Finally, analytical assessments conducted utilizing established nominal axial force‐bending moment (N–M) diagrams test specimens analytically determine column capacity. findings validate devised N–M precisely forecast failure loads
