This work describes the procedures used in the manufacture and assembly of prestressed concrete hollow core slab systems, along with recommendations for presentation and implementation of projects in order to optimize the ...

Este trabalho analisa numericamente o comportamento de lajes alveolares protendidas de uso corrente no Brasil quanto ao cisalhamento, para diferentes situações: sem capa estrutural, com variações na protensão e no ...

The floors consist of hollow core slabs are being increasingly used in Brazil, because it can overcome large spans, have a low self-weight, allow fast assembly, require no shoring in many situations and are more economical ...

Prestressed precast concrete hollow core slabs used as floor is becoming increasingly current in Brazil. Being quickly assembled and with competitive price, this solution provides an efficient section given by the reduction ...

To obtain the strength supported by hollow core slabs it is necessary to perform standardized destructive tests, and in these tests it is possible to verify the product's compliance with the design. ABNT NBR 14861 (2011) ...

The use of precast elements has become crescent in Brazil, due to the need of haste during production as well as while assembling the structures. Bearing in mind a quick assembly and the competitive price for this kind of ...

This work aims to present an updated structural design script for prestressed hollow core slabs and to construct an overview about their manufacture in the Southwest and South-Central regions of Paraná, making it possible ...
