Abstract :
Fires have become a worldwide concern,
causing significant damage to multi-story reinforced
concrete frame structures. Indian codal rules mandate
the use of rectangular or circular ties in reinforced
concrete beams based on their geometry. However, fire
weakens load-bearing materials such as beams, which is
a significant cause of structural damage. Construction
fires in India claim the lives of 2000-3000 people each
year. This study aims to assess the performance of
modified Bamboo reinforcement before examining beam
performance. Bamboo reinforcement is treated with
epoxy and fiber mat to increase its strength, but it swells,
leaving a space between concrete and reinforcement. The
study involves reinforcing bamboo with steel- reinforced
concrete beams, estimating their moment of resistance,
and designing resistance-moment beams. Under and
over- reinforced beams will be created to study their
behavior, and epoxy-coated bamboo reinforced beam
combinations will be testedagainst their MR values. The
study explores the failure patterns of these beams,
including reinforcement quantity, shear reinforcement,
and bamboo-induced beam ductility. The need for fire
prevention, repairs, and retrofitting of structures is
crucial, as most structures permanently damaged by
fires impact infrastructure economics. Therefore, the
goal is to improve building resistance, particularly beam
resistance, so structures can be used after a fire.
Decreasing tie spacing increases section moment
capacity at ambient temperatures, improving
confinement. However, knot spacing below 100 mm has
little benefit during a fire.
