Dimensionamento de lajes alveolares

Abstract

The use of precast elements in constructions has increased a lot. In this way, it is necessary to provide tools to facilitate their use and disclose. In this work, the highlighted point was the design of hollow core slabs to educational and professional purpose. In this way, were studied worksheets that ensure the sizing of those slabs based on checks for situations of latest services and standards based on Brazilian Association of Technical Standards. Thus, according to some principles found in prestressed concretes, the point was trying to find the most appropriate solution for the design of slabs. To help to understand the spreadsheets , it was produced a technical manual describing the entire calculation script which has all the formulas, considerations and limitations adopted in this study to assist the understanding of spreadsheets. To assist in the assimilation of sizing, it was developed an example to expose a circumstance that occurs in design practice, commenting on the results obtained and the considerations taken. For a better understanding, it was described and illustrated the process of production and assembly of a hollow core slab through a visit to the factory of T & A prefabricated and a construction of the Shopping RioMar Fortaleza, with the intention of spreading characteristics of the slab and assist in its dissemination.
