Alternativa de sistemas de lajes para edifício em aço: um estudo comparativo

Abstract

This work is aimed at studying slab systems for steel structures by assessing massive conventional slab, framed slab, pre-cast slabs, compsite slab systems and other systems of steel and concrete. Characteristics as well as structural and building advantages and disadvantages of each slab system for steel structures usage are addressed. Based on a defined architecture, a structural project will be developed in which the main structure (columns and beams) is supported by steel structure, and several solutions using different slab systems will be technically presented according to the methodology for mounting them, execution, and cost comparisons. A more realistic evaluation of each slab system studied was sought by comparing them to each other in terms of structural behaviour, building techniques, and cost.
