Análise da efetividade do pré-dimensionamento estrutural de Ching, Onouye e Zuberbuhler em lajes maciças convencionais

Abstract

The structural pre-dimensioning presents simple formulations for the determination of the initial dimensions of the structural elements of a building, with the intention of minimizing major subsequent changes. The study presents pre-sizing methods applied for use in conventional solid slabs, as well as the characteristics of this system, and the calculation methodology of the same. The work analyzes slabs of a commercial building located in Bento Gonçalves - RS. Subsequently, a comparison is made between the results obtained for the initial thickness given by the pre-dimensioning and the final thickness reached after structural analysis using the Eberick® v9 software. In the end, the study verified a great efficiency of the pre-sizing system, with the exception for slabs with free edges, with these presenting greater differences of results (sic).
