    Adequação estrutural dos pilares de um edifício residencial em concreto armado na cidade de Rio Branco
    (Universidade Federal do Pará, 2013-11-06) SANTOS, Mateus Silva dos; OLIVEIRA, Dênio Ramam Carvalho de; http://lattes.cnpq.br/1324105476558186
    The recovery and strengthening of reinforced concrete structures are increasingly common in Brazil, mainly due to the aging of structures built in the 60s and 70s of the twentieth century, which are close to reaching their lifetime. Added to this, factors such as the use of concrete with low strength, execution failures, improper use and lack of maintenance. Due to these factors that society should endeavor to enhance and / or restore these buildings, thus avoiding demolition of the same and even avoid fatal acidentes. This paper presents a case study that aims to recover a building that is abandoned for nearly two decades in the city of Rio Branco, Acre State. Currently, there are various techniques for strengthening reinforced concrete structure. Such as reinforcement through reinforced concrete jacketing, supplemented or enhanced with added armor, enhanced with application of metal sheets and profiles, reinforcing pillars reinforced with carbon fiber (PRCF), among other. In this work, the method adopted for recovery was enhanced by reinforced concrete jacketing. And for a better understanding of the methodology adopted work also presents details of the enhanced configuration adopted, constructive detail and executive procedures of the method adopted. In addition, the wrappers showing the active and resistant efforts before and after the booster.

    Técnicas de reforço estrutural para edificações antigas: estudo de caso na cidade de Rio Branco – Acre
    (Universidade Federal do Pará, 2013-11-05) AMORIM, Denis Cley de Souza; OLIVEIRA, Dênio Ramam Carvalho de; http://lattes.cnpq.br/1324105476558186
    This study aimed to demonstrate the design and verification of calculating the NBR 6118 (ABNT, 2007) with their geometric characteristics, encasing armor, armor, and buckling resistance of the compression pillars centered pillars of reinforced concrete, with the major bibliographic techniques for structural reinforcement of concrete columns for old buildings, identifying the main methodologies and techniques used in Brazil and presenting the strengths and weaknesses of each technique: concrete jacketing, steel profiles, steel plate glued, blanket / carbon cloth , aramid and glass and polymers reinforced with carbon fiber (CFRP). The pillars with increased rectangular cross section, with added frame and concrete, being the most common and practical technique presents difficulties in ancient works, usually due to architectural need to remain as true to its original form. Justifying the need for knowledge of the various techniques described in this work structural reinforcement with increased resilience, without any substantial increase in the cross section of the pillars and objective analysis of the proposed enhancement through the design calculations, program - PDOP 2.0 and parameters for calculating the NBR 6118 (ABNT, 2007). The results obtained by comparative analysis of reinforcement performed in the case study "revitalization of the old house" - with respect to the analysis of rectangular pillars subjected to bending oblique shear and torsional as the NBR 6118 (ABNT, 2007) using the program optimized design of columns - PDOP 2.0 - indicated that the reinforcement technique was studied efficient because all reinforced parts had a greater bearing capacity than the original pillar without strengthening.
