Abstract

Modular systems are widely used in various building types including housing, dormitory, and barracks. Steel studs have many advantages over other materials as construction components of modular buildings in terms of seismic performance, durability and maintenance. However, steel stud modular systems also have weakness in condensation resistance due to high thermal conductivity of steel. The purpose of this study is to investigate the condensation resistance of steel stud wall corner details in modular buildings by thermal simulation. The condensation resistance was evaluated by temperature difference ratio according to ISO 13788. The result showed that there was little difference between the alternatives of adding cavity and insulation. Separation of interstitial steel studs showed outstanding effect on the improvement of temperature difference ratio.
