Abstract
This study aims to construct the performance data for smoke-control zone and realize the safety of injection and pressurization room which is composed of supply air pressure zone, vestibule, smoke-control zone and stairwell. To obtain this, smoke-control system and the device of the opening-closing force of fire door are manufactured. This subject is the analysis of the closing force, angular velocity and fire door size in the case of fixed volume flow rate. Based on the results, closing force increased as fire door size and closing angular velocity increases. Also, it is remark that there exists a critical angular velocity, which maintains constant maximum closing force even though the angular velocity increases more.
