Decking provides the work surface of a mezzanine as well as providing the structural floor to carry the design load. There are three type of decking options. Solid, composite or open style. Each style has its own characteristics and features that influence performance and durability of a mezzanine floor. Selection Factors: 1. Type and magnitude of loading. A. Uniform B. Concentrated C. Dynamic 2. Types and extent of traffic. A. Foot B....

Height: Height is determined by importance of under-clearance and code restrictions. Is the distance from ground floor to the mezzanine deck surface or the mezzanine under-clearance more important? Headroom above the mezzanine deck should also be considered. Codes typically dictate minimums. Loads: What types of load will be on the deck? Relative or concentrated? Column Spacing: Will mezzanine columns be potential hazards for traffic and...

Loading requirements, column spacing, flexibility of design, deflection, seismic considerations at the project location and supporting sub-structure must be considered regardless of the type of mezzanine. Loading A uniform load is one that is spread out evenly over the deck surface. A uniform load can be  determined by dividing the total load  [live applied] load plus dead weight. (decking, framing, sprinkering, lighting etc…) by...
