Tendo em vista que uma melhor concepção de um projeto estrutural pode melhorar o desempenho dos elementos estruturais, proporcionar um aumento nos vãos dos mesmos e diminuir insumos que tem maior significância no custo final da obra, através de materiais com menor peso para compensar materiais sem função estrutural e pesquisa sobre o comportamento e a interação entre lajes em balanço e as adjacente a mesma, a fim de determinar as dimensões limites dos vãos para lajes maciças e nervuradas e como conceber as lajes adjacente para proporcionar melhor desempenho na laje em balanço. Para tanto, é necessário estabelecer valores máximos de esforços para o dimensionamento em função do vão e das lajes adjacentes, comparar as taxas de armadura por metro construído estabelecer qual a influência gerada no elemento quando se tem um variações de dimensões nas lajes adjacentes e no comprimento em balanço. Realiza-se, então, uma pesquisa de natureza descritiva no que diz respeito aos objetivos e quantitativa com relação aos resultados, pois será feito um comparativo entre os consumo de insumos, esforços e deformações máximas de elementos estruturais executados em duas tecnologias, valores que serão obtidos a partir dos cálculo realizados em um software de dimensionamento de concreto armado, CypeCad. Diante disso, verifica-se que as lajes maciças apresentam comprimento máximo em balanço de 3,00 m com uma espessura de 15 cm e as nervuradas 4,00 m com 35 cm, as lajes apresentaram as mesmas características de curvatura após as deformações, mas com valores distintos, as lajes nervuradas atenderam os limites máximos prescritos as normas brasileiras e as maciças tiveram poucos casos que atendiam esses limites, os esforços máximos ocorreram sempre nas lajes maciças quando comparado as mesmas plantas de forma e os esforço, independente da região, tiveram comportamento semelhante a curvas de 2° ordem conforme aumentava o comprimento do balanço com poucos pontos que fugiam desse padrão, lajes com comprimento inferiores na direção y (perpendicular ao balanço) apresentaram menores consumos de aço para a execução das lajes e que o alongamento no sentido do balanço favorece ainda mais para diminuir o consumo, o que impõe a constatação de que as lajes nervurada apresentaram vários benefícios para ser tomada como técnica a ser utilizada e que a melhor disposição da laje associada à um balanço é dimensões maiores no sentido do balanço e menores na direção perpendicular. 2020-11-14T17:20:24Z 2020-11-14T17:20:24Z 2019-07-04 bachelorThesis ALVES, Tiago Oliveira.

Considering that a better design of a structural project can improve the performance of the structural elements, provide an increase in the spans of the same and reduce inputs that have greater significance in the final cost of the work, through materials with lower weight to compensate materials without function structural analysis and research on the behavior and interaction between adjacent and adjacent slabs in order to determine the boundary dimensions of spans for solid and ribbed slabs and how to design the adjacent slabs to provide better performance on the slab. To do so, it is necessary to establish maximum values of effort for the design according to the span and adjacent slabs, to compare the armature rates per meter constructed to establish the influence generated in the element when there is a variation of dimensions in the adjacent slabs and in the length on balance sheet. A research of a descriptive nature with regard to the objectives and quantitative with regard to the results is carried out, since a comparison will be made between the consumption of inputs, efforts and maximum deformations of structural elements executed in two technologies, values that will be obtained from the calculation performed in a software of sizing of reinforced concrete, CypeCad. In view of this, it can be verified that the massive slabs have a maximum balance length of 3.00 m with a thickness of 15 cm and the ribs 4,00 m, the slabs presented the same curvature characteristics after the deformations, but with different values , the ribbed slabs met the maximum limits prescribed by the Brazilian norms and the massive ones had few cases that met these limits, the maximum efforts always occurred in the massive slabs when compared to the same shape plants and the effort, independent of the region, had similar behavior to second-order curves as the balance length increased with few points that deviated from this standard, slabs with lower lengths in the y direction (perpendicular to the balance) presented lower steel consumption for the slabs execution and that the elongation in the balance direction favors even more so as to reduce consumption, which makes it necessary to note that the ribbed slabs the benefits to be taken as the technique to be used and that the best arrangement of the slab associated with a balance sheet is larger in the direction of the balance and smaller in the perpendicular direction. |
