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.

带腹板开口的复合梁和复合单元格梁的进展

摘要 近二十年来，土木建筑使用钢构件来构成结构框架。钢和混凝土复合构件在多层建筑中的使用已在多个国家获得市场份额，这主要是由于降低建筑高度、结构自重和执行速度的可能性。在 1990 年代初期，由于自动化切割和焊接的发展，开始制造具有连续腹板开口的梁。多层建筑设计工程师面临许多挑战，例如分区规定的高度限制，以及需要匹配楼层高度。在这种情况下，使用具有腹板开口的复合梁是一种有利的工具。本文旨在介绍带腹板开口的组合梁和组合单元梁的开发背景，考虑到传统楼板，其中混凝土板放置在钢型材的上翼缘上。介绍了研究，首先考虑带腹板开口的组合梁，然后考虑由实心板和组合板形成的组合单元梁。总结了复合蜂窝梁的结论和未来的研究方向。
