Nonlinear-finite-element analysis of reactive powder concrete columns subjected to eccentric compressive load

Abstract Studies on the behavior of reactive powder concrete (RPC) columns under eccentric loading are limited. The effect materials used in manufacturing these RPC has not yet been investigated. This research aimed to perform a nonlinear-finite-element analysis determine load-carrying capacity and displacement made different mixes subjected various eccentricities. investigates two types parameters. first parameter is column’s geometric parameters (the height L load eccentricity distance e ). second material (regarding silica fume or fly ash as pozzolanic type fibers used, whether steel glass fiber). Results indicate that eccentric-loaded slender exhibit much less than corresponding short columns. 2 m-long with ratio / t = 0.2 resulted 65% average reduction ultimate (Pu) compared 1 Using instead reduces an column by 60%. also reduced Pu 50%. percentage increase maximum vertical deflection (Δ y max ) ( m) found range 18–31% for 0.1 but 45–69% 0.2. In contrast, m), Δ 10–30% both
