ENSAYO A TORSIN EN PERFILES EN I DE CONCRETO CON ACERO DE REFUERZO Y/O FIBRAS DE ACERO.

Nelly Carolina SalasEdgar Fernando RuizMara Martha SarmientoJuan Guillermo JaramilloJos Leonardo MoraNicols OrozcoWilmer Mauro

OBJETIVOS Practicar y analizar el proceso fsico de torsin y deformacin del concreto reforzado con estribos con una distribucin especificada.

Construir e interpretar la grfica Giro Vs Momento torsor.

Comparar el comportamiento que tiene la seccin con barras longitudinales mas estribos y con barras longitudinales mas fibras.
