Abstract

PARA EVITAR LA FORMACION DE GRIETAS QUE PERMANECEN EN TRAVIESAS DE HORMIGON PRETENSADO DE ALTAS SOLICITACIONES CON UNION POSTERIOR, SE PROPONE COMO ARMADURA DE TENSION, EN LUGAR DE LAS BARRAS DE TENSION UTILIZADAS HASTA AHORA AHORQUILLADAS DE FORMA PLANA, LA UTILIZACION DE ACERO PERFILADO EN FRIO.TO AVOID THE FORMATION OF CRACKS THAT REMAIN ON PRE-TENSIONED CONCRETE CROSSBARS OF HIGH REQUIRED JOINTS, IT IS PROPOSED AS A TENSION ARMOR, INSTEAD OF THE FLAT-FORCED TENSILE BARS IN PERIL, LA UTIL.
