No. of bitstreams: 1 DissFLR.pdf: 3397805 bytes, checksum: 748cef78a5c04d386df8100510a2b742 (MD5) Previous issue date: 2015-08-24 / Não recebi financiamento / The civil construction more than ever is challenged by the circumstances faced by the country, the economic crisis experienced in these last few years puts into perspective the necessity of more rational choices avoiding unnecessary dispenses and wastes. In face of this scenario the pre-cast elements became vital to guarantee the conclusion in less time and trying to reduce constructive bottlenecks. The latticed pre-cast concrete slabs are one of the many types of pre-cast parts which can be used at the construction sites, however the national standards are confuse and vague about some aspects contained especially in the European standards. Even the last review of the NBR 6118 of 2014 adds little about the issue and the more specific standard (NBR 14680) has few constructive details regarding the connection between elements and the calculus procedures, therefore this work tries to discuss the main questions related to this kind of pavement, introduces knowledge coming from other standards trying to answer some less usual doubts, but extremely pertinent ones such as, for example, the concept of self-portance, the use of this material in bridge floors and also the type connective reinforcement needed to attain the effective monolithism at the interface between beamstructure. This dissertation also presents some examples of pre- and post-constructive deflection limits, fissured deformation and a full example of calculation for a common pavement. Some data from the experiments realized at the NEPRE in the University of São Carlos and their practical application are shown as well. / A construção civil mais do que nunca se vê desafiada pelas circunstâncias enfrentadas pelo país, a crise econômica vivida nos últimos anos coloca a necessidade de escolhas mais racionais evitando gastos e desperdícios desnecessários. Em face deste cenário as peças prémoldadas se tornaram vitais para garantir prazos menores e redução de gargalos construtivos. As lajes pré-moldadas do tipo painel treliçado são um dos muitos tipos de peças pré-fabricadas que podem ser utilizadas nos canteiros de obra, porém as normas vigentes são confusas e vagas em relação a alguns aspectos celebrados principalmente nas normas europeias. Mesmo a última revisão da NBR 6118 de 2014 acrescenta pouco sobre o assunto e a norma mais específica (NBR 14860) possui poucos detalhes construtivos relativos à ligação entre elementos e a procedimentos de cálculo, portanto este trabalho tenta abordar as principais questões relativas a esse tipo de pavimento, introduz conhecimento vindo de outras normas na tentativa de responder a algumas dúvidas menos usuais, porém extremamente pertinentes como, por exemplo, o conceito de autoportância, o uso desse material em pavimentos de pontes e também o tipo de ancoragem necessário para se atingir o monolitismo adequado da interface vigaestrutura. O trabalho ainda apresenta exemplos de cálculo de flecha limite pré e pós-construtiva, deformação fissurada e um dimensionamento completo de um pavimento. São apresentados também os dados coletados durante os ensaios realizados no NETPRE da Universidade Federal de São Carlos e sua aplicação prática para aqueles resultados.

El desarrollo de la presente investigación académica tiene como área de estudio a la gestión de proyectos de Ingeniería Civil. Hemos apoyado el documento en los lineamientos del PMBOK (PMI, 2016) 6ta edición (PMI) y consideramos como factores importantes el desarrollo del cronograma, costo y calidad de proyectos edificados con el uso de prelosas de la compañía “BETON DECKEN”, considerando que fue aceptado como método de construcción no tradicional en el Perú por la Resolución Ministerial N°069-2018-VIVIENDA en febrero del 2018. Como situación problemática, hemos considerado la cuantificación de mano de obra empleada para las actividades correspondientes a las partidas que involucran pre-losas. Dado que, de acuerdo a los antecedentes de uso, este elemento era considerado generalmente en construcciones del sector retail y no en viviendas. Esto, debido a las particularidades de la construcción. Es por ello, que, en la resolución emitida, se muestran datos aplicados a las construcciones retail y no a viviendas. Nuestro propósito es plasmar los resultados obtenidos a través del seguimiento de las partidas (rendimiento) y, mediante herramientas de gestión, optimizar el proceso mejorando la calidad, tiempo (cronograma) y costo en un 15% de lo proyectado para Edificios Multifamiliares construidos con pre losas en Lima Top. Se validará la investigación mediante los métodos explicativo, descriptivo, exploratorio y correlacional. / The development of this research academy has as a study area the management of civil engineering projects, we have supported the document in the guidelines of the PMBOK (PMI, 2016) 6th edition (PMI). We take as important factors the development of the schedule, cost and quality of projects built with the use of pre-slabs of the company “BETON DECKEN” considering that it was accepted as a method of non-traditional construction in Peru by Ministerial Resolution No. 069-2018- VIVIENDA in February 2018. We have considered as a problematic situation the quantification of labor used for the activities corresponding to the items that involve pre-slabs. Given that, according to the history of use this element was generally considered in retail constructions and not in homes due to the particularities of the construction. That is why, in the resolution issued, they provide data applied to retail constructions and not to homes. Our purpose is to capture the results obtained through the monitoring of the items (performance) and through management tools to optimize the process by improving the quality, time (schedule) and cost by 15% of the projected for Multifamily Buildings built with pre-slabs in Lima Top. Research will be validated between the methods explanatory, descriptive, explorer and correlationally, / Tesis
