Analytical Study of Rectangular Concrete-Filled Tubes (RCFT) Connections using Finite Element Analysis under Cyclic Loading

Recent condition of the earthquakes model has shown that rectangular concrete-filled tubes (RCFT) with weld connection are so brittle. According to studies conducted, large damages due cracking between beam flange and column face inducing concentrated stresses in this area. One novel alternatives reduce stress concentration at panel zone could be use section (RBS). Given enormous impact seismic behaviour ductility zone, RBS moves plastic hinges formation an appropriate distance from face. In study, 2 major RCFT without have been modeled using ABAQUS computer program compared under cyclic behaviour. The obtained result study showed is more ductile implied a good stability. It also will consider having better than other connections.
