Estudo comparativo do dimensionamento de vigas mistas entre os métodos usuais de cálculo e o de softwares

Abstract

The use of steel-concrete composite structure expands the possibility of solutions for various structural problems within the construction industry. Given that in steel-concrete composite columns, for example, the steel's contribution to the piece's resistance can reach 90%, with the opportunity to use various types of profiles. Within universities, due to tight schedules and lack of emphasis on these types of structures, civil engineering students graduate without knowing how to design composite beams, columns, and slabs, which are common components within the construction market. With this focus, the objective of the work is to demonstrate the usual processes of calculating composite beams, as well as to make a comparison with the Eberick method using a typical building as a basis for analysis. To analyze out the differences and similarities between the two design methods, a calculation spreadsheet produced by the author was used to obtain the results for bibliographic calculations and compare them with the data taken from the software. It was concluded from the results that the program may end up oversizing the structure considering that it only works with the steel section, not considering the slab as a collaborating part of the structure, making Eberick less efficient for the design and dimensioning of steel-concrete composite beams.
