External Confinement with Basalt Fiber Ropes in Existing Reinforced Concrete Structures

Abstract Existing reinforced concrete structures designed according to previous generation seismic codes, often suffer from premature, abrupt and detrimental failures in cases of intense earthquakes. In this study the response an existing building is analytically investigated while taking into account influence different detailing brick wall infills. The assessment performed with 3D static inelastic (Pushover) or incremental Dynamic time‐history analyses (IDA) SeismoStruct Software. Buildings inadequate performance receive continuous transverse pre‐tensioned Basalt Fiber Ropes (BFR) as external shear confining strengthening reinforcement. conclude that buildings short columns early collapses at low top displacements due local failure above‐mentioned members. Both crush confined related critical are eliminated overall base strength increased. BFR wrapping increases ultimate well. IDA thoroughly elaborated assess collapse mechanism displacement values for under investigation.
