Progressive Collapse Resistance of GFRP-Strengthened RC Beam–Slab Subassemblages in a Corner Column–Removal Scenario

Dynamic performance of a real-scale reinforced concrete building test under a corner-column failure scenario

“…to impact). Existing tests on corner column removal focused on subassemblies of frames or flat slab structures under monotonic loads applied by an actuator [29,32,33,[35][36][37][38][39][40][41]. Only tests by Xiao et al [42,43] and Zhao et al [44,45] considered complete, but not full scale, structures and only the experimental study by Xiao et al [42,43] was performed under a real sudden loss of a corner column.…”

Response of RC Beam-Slab Structure Strengthened with CFRP under Sudden Corner Column Removal Scenario

“…The different failure mechanism from starting to local bending failure which were flexural action, tensile membrane action, one-way catenary and dowel action to resist the applied load and also 98% of the applied concentrated loads was transferred to the edge columns when the central column removed suddenly studied by (Huizhong et.al, 2018).The progressive collapse of beam-slab subassemblies structure when the corner column lost suddenly under concentrated load at the above lost column and distributed load on the slab studied by (Namyo, 2017) and ,respectively. The Progressive collapse and strengthened of beam-slab subassemblies in a corner column removal scenario studied by (Feng et.al,2019) and also investigate the behavior of progressive collapse after strengthened by externally bonded GFRP laminated and near surface mounted (NSM) GFRP bars. In the United States the interest in fiber-based reinforcement for concrete structures started in 1930's.…”

“…The effectiveness of the degree of CFRP stripes at the tension face of the reinforced concrete flat slab throughout sudden removal of corner column against progressive collapse investigate by (Qian and Li, 2013). (Feng et.al, 2019) And (Namyo, 2017) studies the progressive collapse of beam-slab subassemblies under corner quasi-static load above the removed column and ) studies 8-point load on the slab having the assumption of pertaining uniformly distributed load. From the above mentioned researches the study done by )on a progressive collapse of slab during the sudden removal of column under uniformly distributed load found to be more realistic to study.…”

A Parametric Computational Study of RC Building Structures under Corner-Column Removal Situations

“…Few experimental studies are available on reinforced concrete (RC) building structures, particularly on purpose built full-scale structures subjected to sudden removal of columns [28,33]. Most of the cases studied with sudden column removal have been on subassemblies, including cases involving internal and edge columns (e.g., Qian et al [34]) and, to a lesser extent, on corner columns (e.g., [35]), although the columns in the latter case are more vulnerable to accidental events [28]. Due to the small number of tests on full-scale buildings, only a few of the computational models found in the literature have been fully validated.…”
