Abstract

This study focuses on structural design, which is a primary aspect of civil engineering. Investigating the behavior of reinforced concrete (RC) frame systems subjected to lateral loading and estimating the damage state of a structure still remain challenging tasks in civil engineering. Reinforced concrete is currently used in a majority of constructions and Conventional buildings remain vulnerable to seismic earthquakes. The aim of this research is to identify how well RC frames with basalt and steel fibers perform under cyclic loading. Steel and basalt fibers are chopped to a size of 2.5 cm. The reinforcements details are made according to IS 13920-2016. The concrete specimen used for this work is in the form of a single-bay, two-story frame, which is composed of reinforced concrete along with chopped steel and basalt fibers of two different proportions. Three frames are cast. One is a RC concrete frame with no fiber materials (conventional concrete) and the other two frames are cast with different proportions of fiber content. The basalt fiber is added to the specimens in proportions of 0.25 % and 0.50 %. The experimental outcome attained from the specimens of 0.25 % of basalt fiber has superior load-carrying capacity as well as minimum story drift than the other two frames. The ductile behavior of BFRC is increased compared to that in conventional ones. It is observed that the crack width of the BFRC is less when compared to that in the conventional concrete.
