Experimental Study of the Welded Connections of Composite Columns Filled RCFT with Concrete with Steel Beams Type I

The behavior of five types of welded connections of composite columns rcft (rectangular tube filled with concrete) and type i steel beams used in ecuador, all made with the same materials, dimensions and construction processes, has been compared, modifying the form of the connection, this being the only variable to investigate. By performing experimental cyclic tests following the loading protocol defined by ansi / aisc 341-16, 2016, it was possible to determine the real behavior of these connections, obtain the necessary hysteresis curves, define which test piece of the tested ones presents a better behavior and energy dissipation capacity, as well as analytical models of the tested specimens, were made using finite element methods for comparison.
