Experimental research on the fire resistance of columns in container-style steel modular buildings

Year: 2025

Type: article

Abstract: This study investigates the fire resistance of columns in container-style steel modular buildings through fire tests. Three individual columns and one combined column were tested to evaluate the fire resistance performance of various protective measures: fire-resistant coatings, calcium silicate boards, and rock wool sandwich panels. The combined column protected by 75 mm rock wool sandwich panels achieved a fire resistance limit of 102.1 min. The study concludes that rock wool sandwich panels are a feasible, economical fire protection solution for such columns. The required thickness of rock wool for different fire resistance limits was calculated, providing valuable design insights for container-style steel modular buildings.
