Abstract

In the last two decades, civil construction has used steel elements to compose the structural framework. The use of composite elements of steel and concrete in multi-storey buildings has been gaining market share in several countries, mainly due to the possibility of reducing the height of the building, the structure's own weight and the speed of execution. In the early 1990s, due to the development of automated cutting and welding, beams with sequential web openings started to be manufactured. There are many challenges for multi-storey buildings design engineers, such as the height limitations that are stipulated by zoning, and the need to match the height of the floors. In this context, the use of composite beams with web openings is an advantageous tool. The article aims to present the background that has been developed on composite beams with web openings and composite cellular beams, considering conventional floors, in which the concrete slab is placed on the upper flange of steel profile. Studies are presented, considering firstly composite beams with web openings, and later the composite cellular beams, formed by solid and composite slabs. Concluding remarks and future research directions of composite cellular beams are presented. (c) 2020 Elsevier Ltd. All rights reserved. (AU)
