Design of Earthquake Resistant Structure Using Cabkoma Strands: A Review

Abstract

Abstract: Earthquakes are the indication for transformation of earth internal surface. The Indian subcontinent has suffered some of the greatest earthquakes in the world. Many research studies have been focusing on decreasing the impact of seismic waves on structures. For this initially there were many passive techniques introduced to reduce the damage caused due to earthquakes which are based on decreasing the lateral loads on structures. But since the late twentieth century the focus has shifted to introduce active earthquake techniques which are meant to absorb the seismic waves or do not let the waves propagate through the building. Though it is not possible to prevent an earthquake, the least that can be achieved in reducing the damage is to make the buildings earthquake resistant with the advancements in earthquake resistant techniques. The major goal of this dissertation is to use CABKOMA strands to create a novel earthquake-resistant technology. In this study, CABKOMA strands are used to examine the seismic response of ordinary moment resisting steel framed structures of high rise, mid-rise, and low rise analyzed with and without strands to determine the workability of cabkoma strands. To determine how well the intended structures function against earthquake motions, a comparative examination is done between them. Additionally, this work shows a comparative analysis of the seismic behavior of high-rise, mid-rise, and low-rise steel structures designed utilizing CABKOMA strands with the seismic behavior of high-rise steel structures designed using bracings an existing earthquake technique, by varying the arrangement of strands at the corner, Centre, and both centre and edge of the structures. Eventually, this work presents cabkoma strand optimization for effective strand utilization by varying strand to strand spacing from 0.5m to 1m while maintaining the same strand positioning.
