1. Análise experimental de vigas pré-formadas de concreto armado à flexão e ao cisalhamento / Experimental analysis of reinforced concrete preformed beams to bending and shear
Reinforced concrete preformed beams are structural elements which present a thin superficial precast concrete layer that defines their geometrical shapes. This superficial layer functions as a formwork that will be incorporated to the beam after the introduction of cast in loco concrete, which will consolidate the structure. This construction system presents

2. Flexural strengthening and stiffness increasing of precast beam-to-column connections by NSM CFRP strips / Reforço e incremento da rigidez à flexão de ligações viga-pilar de estruturas de concreto pré-moldado com polímero reforçado com fibra de carbono (PRFC)
This work presents the development of a technique for flexural strengthening and stiffness increasing of precast beam-to-column connections by the embedding of FRP strips into grooves made on the concrete cover. According to this technique, the tension in the connection is transferred by the Near-Surface Mounted (NSM) FRP strips. To allow the transference of

3. Contribuição à inspeção, diagnóstico e procedimento de reabilitação de poste de concreto armado centrifugado utilizado em telefonia celular. / Contribution to the inspection, diagnosis and rehabilitation procedure of centrifugally cast concrete post used in telecomunication market.
Precast reinforced concrete posts were installed in Brazil by mobile telephone companies when implanting and enlarging service areas of the system starting in 1996. The great majority of these posts were manufactured by a single company, using a centrifugal process. Approximately two thousand units of posts were produced of heights ranging between 20m [60 ft

4. Interpretação de deformação e recalque na fase de montagem de estrutura de concreto com fundação em estaca cravada / Strain and settlement interpretation in the assembly of a concrete structure supported by driven piles
Although encouraged by several authors and by the Brazilian Foundation Code, reports of actual column loads measurement in natural scale are not frequent in our technical literature, especially in the case of buildings supported by deep foundations. Results of load and settlement measurements at 20 contiguous columns of a structure built in pre-cast reinforc
