Mixed Steel Deck Systems and Their Applications in Civil Construction: A Comprehensive Review

Composite steel–concrete systems have significantly transformed structural engineering practices over the last decades. Among these systems, the steel deck slab—also known as composite slab or collaborative slab—has become one of the most efficient solutions for multi-story buildings and industrial structures. This review article presents a comprehensive analysis of the historical development, structural behavior, design principles, execution methods, advantages, limitations, economic impact, sustainability aspects, fire resistance considerations, and maintenance requirements of steel deck systems. The study consolidates technical literature, Brazilian standards (NBR 8800 and NBR 6118), and international…
