Flexural Performance of Exterior Steel Fiber Reinforced Self-Compacting Concrete Beam-Column Joint Subjected to Reversed Cyclic Loading

Abstract

Beam-Column Joint plays an imperative part in the seismic enactment of Reinforced concrete moment resisting frame. The response of the structure under the earthquake loads mainly depends on the behavior and performance of the Beam-Column Joint (BCJ). An experimental investigation on exterior reinforced beam-column joints done using steel fibre reinforced self-compacting concrete subjected to reversed cyclic loading is presented in this investigation. The attempt has been made to demonstrate the influence of steel fibers reinforced self-compacting concrete (SCC). Three exterior beam-column joints having the same geometry were cast and tested through reversed cyclic load using displacement-controlled mechanism. All three specimens are designed adequately in accordance with IS 13920:2016 code. The hysteresis loop, ductility factor, stiffness degradation, energy dissipation characteristics, and damage propagation are considered to quantify the response of joint specimens. The results show enhanced ductility, energy dissipation capacity and damage tolerance behavior with the increase in steel fibers percentage in SCC.

A Study on Self‐Consolidate Concrete in Experimental Reinforced‐Concrete Beam Column Structures with Alccofine and Steel Fiber

“…Te beginning hardness of Alccofne-1203 concrete is similar to or higher than that of silica because it initiates the fundamental process after hydrating, and Alccofne also absorbs by-product hydroxide ions from production of cement from added C-S-H gel that is comparable to pozzolana. Based on the material size distribution, the calculated selection of the participants number is roughly 1200 cm 2 /gm, which is genuinely nanoscale. It improved the decrease of cementitious and enlarged slump retention without growing the contaminant intermixing dosage, as well as being quick and efcient, it forced to close removal, fast form line up in the prefabricated concrete industry, and improved the percentage of resilience acquired in concrete mixtures with pozzolanic material resource components such as fy ash, GGBS, and others.…”

“…Te attempt has been made to demonstrate the infuence of steel fbers reinforced selfcompacting concrete (SCC). Te results show enhanced ductility, energy dissipation capacity, and damage tolerance behaviour with the increase in steel fbers percentage in SCC [2]. Analysis of beam column joints prepared using selfcompacting concrete (SCC) is incorporated with nanosilica (NS) and recycled coarse aggregates (RCA).…”
