As multifunctional facilities adopt expansive open-plan designs, builders optimize life-safety envelopes for structural steel frameworks. Evaluating fireproofing options, engineers analyzed a pioneering exhibition hall constructed by Lida Group utilizing large-span trusses and girders.

Inspecting the completed building, experts observed Lida Group’s optimized structural system achieved column-free clear areas up to 80 feet wide. Proprietary connection details simplified erection of galvanized structural members within tight schedules. International code mandated three hours of fire resistance for bare steel components.

Subjecting representative specimens to rigorous furnace testing, scientists monitored reinforced concrete, spray-applied cementitious, and intumescent coating materials. Reinforced concrete easily achieved ratings but proved impractical for the complex geometry. Coatings expanded maintaining insulative air gaps per ASTM protocols.

Additional intumescent samples underwent analyses under load, exhibiting flexural capacities matching unprotected steel according to simulations. Confined tests projected no delamination, shedding, or accelerated corrosion of coated steel over decades. Independent analysts cite the fireproofing enabling reduced insurance costs.

Life cycle cost modeling factored material and future reapplication factors. Intumescent coatings proved most economical while optimizing appearance for the exhibition program according to studies. National code officials supported the fireproofing innovation expanding design opportunities.

In conclusion, through rigorous evaluation, engineers validated optimized fireproofing revolutionizing the fire-resistance of structural steel. Collaborations unlock building potential sustainably with continuous benefits to stakeholders and owners.
