AUTOMATION OF SIZING OF PREFABRICATED BI-SUPPORTED LATTICE SLABS

Abstract

This article aims to develop an automated tool for the design of precast lattice slabs with two supports, used in structural systems of civil construction. The research aims to improve the accuracy and efficiency in the design calculation, addressing safety criteria. Initially, fundamental concepts about lattice slabs are presented, including their construction, behavioral and normative aspects, based on current technical standards. The methodology involves the application of calculations in an Excel spreadsheet that integrates loading data and geometric characteristics, resulting in the obtaining of moment efforts, displacements and possible additional steel area. The proposed tool will allow the design engineer to perform fast and accurate analyses, minimizing human errors and reducing the time dedicated to the manual calculation process. As a result, a practical solution is expected that contributes to productivity and assertiveness in concrete structure projects, with potential to be implemented in companies in the sector and in structural engineering offices.
