1. REDISTRIBUIÇÃO DE MOMENTOS EM VIGAS CONTÍNUAS EM ADUELAS PROTENDIDAS COM CABOS SINTÉTICOS EXTERNOS / MOMENT REDISTRIBUTION IN CONTINUOUS SEGMENTAL BEAMS PRESTRESSED WITH EXTERNAL SYNTHETIC TENDONS
An experimental investigation on the behavior of continuous segmental concrete beams, prestressed with external aramid tendons, was carried out. Four beams were tested; one was monolithic and the others were constructed in precast dry- jointed segments. All the beams had the same overall dimensions, with two spans and an I section 30 cm high, flange width of

2. ANÁLISE DO COMPORTAMENTO À FLEXÃO DE VIGAS PROTENDIDAS COM CABOS EXTERNOS SINTÉTICOS / ANÁLISIS DEL COMPORTAMIENTO A LA FLEXIÓN DE VIGAS PROTENDIDAS CON CABLES EXTERNOS SINTÉTICOS / ANALYSIS OF THE FLEXURAL BEHAVIOR OF BEAMS PRESTRESSED WITH EXTERNAL TENDONS
Beams prestressed with external tendons have a number of attractions for engineers. They allow a reduction in weight, since concrete is not provided merely to act as cover to tendon or duct; they allow the tendons to be inspected for signs of corrosion and tendons can be replaced or retensioned if necessary. External prestressing is also an ideal application

3. INFLUENCE OF THE CONCRETE STRENGTH ON THE BEHAVIOR OF PRESTRESSED BEAMS WITH EXTERNAL ARAMID TENDONS / INFLUENCIA DE LA RESISTENCIA DEL CONCRETO SOBRE LA RESISTENCIA DE VIGAS PROTENDIDAS CON CABLES SINTÉTICOS EXTERNOS / INFLUÊNCIA DA RESISTÊNCIA DO CONCRETO SOBRE A RESISTÊNCIA DE VIGAS PROTENDIDAS COM CABOS SINTÉTICOS EXTERNOS
Este trabajo presenta un análisis experimental de cinco vigas de concreto, simplemente apoyadas, protendidas con cables sintéticos externos, con el objetivo de estudiar la influencia de la resistencia del concreto en la variación de la fuerza de los cables de protensión y en la resistencia a la flexión de las vigas. La protensión de las vigas fue hecha
