Structural Behavior Due to Hybridization of Sisal and Nylon Fibers in Concrete

India being a populous country demanding construction on large scale. The change of environment since several years are more often generating seismic waves. Around 9 major earthquakes with magnitude scale of above 6 can be observed over an decade. The present study is to focus in increase in ductility without any earthquake resistance design but with inclusion of combination of fibers like nylon and sisal. Concrete due to its brittleness is very prone in case of seismic resistance alone. Reinforcing concrete with steel bars to strengthen the ductility was the traditional approach which is followed by all over the globe. The use of steel bars to strengthen a concrete beam is confined because of its limitation which causes sudden failure in concrete. Thus, making a concrete material which is more ductile than a normal concrete is basic aim of this experimental research work. T beam are casted to study their performance mainly due to know the behavior of column beam joint during seismic evaluation. The study shows the attributes of concrete due to inclusion of hybrid fibers and even generation of mathematical model to analyze the effect and variation of concrete properties due to inclusion of hybrid fibers. To study their seismic performance cyclic loading test is performed. An trial is made to increase ductility of concrete beams mainly near column beam joint which were very prone towards seismic waves by hybridizing sisal fiber and nylon fiber and can result in increase in ductility and load carrying capacity by 22% and 31% respectively in comparison with control specimen.
