Análise incremental considerando efeitos de retração e fluência em vigas de transição de concreto armado. 2020. 134f. Dissertação (Mestrado em Engenharia Civil) - Centro de Tecnologia, Universidade Federal do Rio Grande do Norte, Natal, 2020.https://repositorio.ufrn.br/jspui/handle/123456789/29993Effects such as the construction process in stages supported by lower floors and deformations caused over time such as creep and shrinkage are not commonly taken into account in conventional structural analysis. For the case of hyperstatic structures and subjected to high loads, the effects of these considerations are even more relevant, as they can be crucial to guarantee the safety of the element. With this, it is essential to carry out an incremental analysis and to know the effects of efforts that the loading of the construction and how deformations due to time can generate in the structures. When conducting a systematic review of studies developed with this theme, it was possible to observe a topicality in the theme with a growing trend in the number of works in the years. Much of the studies found through this review study the slab as an isolated element, so that no studies were found on transition beams or a comparative study in relation to the number of floors in buildings. The work presented here aims to model, in the SAP 2000 V14 software, a residential building with a hyper-static transition beam on the ground floor. The constructive effect, creep and shrinkage will be considered, analyzing a 2D frame, it was sought to identify how these deformations influence the values of maximum moments in the beam in question. In addition, models of the porch were compared, varying the height of the building in order to understand how the number of floors changes the results found. The results show an increase in the positive bending moment in the transition beam as a whole, as well as the displacements, and a reduction in the negative moments in the meeting of columns with beams at different points in the structure. The increases in efforts and displacements between the use of conventional and incremental analysis were greater for porches with more floors, however, if there was a greater percentage variation when the building is lower.Acesso AbertoEdifícios de concreto armadoApoio indiretoEstágios de construçãoDeformações dependentes do tempomasterThesis
