  • According to building law, there are only regulations on the fire prevention compartments that can perform the function of partial smoke compartment, but the building law management of the smoke compartment for effective smoke diffusion prevention and control is not possible. The lack of control on the smoke compartment such as leakage rate on the penetrating part, and the lack of leakage rate in the design of smoke control of fire safety law resulted in the absence of fundamental safety technology. Therefore, this study seeks to find solutions to domestic problems after reviewing relevant domestic laws and regulations.

  • In this study, it analyses the problems of the Fire Compartment in Goyang Bus Terminal. Based on analysed data, it is confirmed the necessity of the Smoke Compartment installation for Protecting the Smoke Spread in Large-Scale Buildings using of FDS(Fire Dynamics Simulation). In addition it suggest that the necessity of Smoke Compartment application method and Development of Design Guideline.

  • This paper deals with the lobby pressurization for smoke control in building fires. A computer program and related modeling technique are presented. The pressure difference between a lobby and a fire area is not able to be same among building floors because an injection fan can not be installed in each floor. The most remote area from the injection fan has therefore the smallest pressure difference if flow areas are not different through all floors. An adjacent floor from the injection fan has possibly too large pressure difference because the most remote lobby must also meet the required pressure difference over the fire area. Moreover this problem will lead to a larger capacity of the fan. It is showed that the fan capacity can be decreased by adjusting the flow area of air supply duct in each floor.

  • In case of fire in a compartmentalized building area, a number of casualties are caused by smoke production. Accordingly, openings, penetrations and joints in compartmentalized spaces should be secured not only for fire resistance but also for smoke-proofing. However, domestic test regulations stipulate test methods for refractory performance of penetrations and joints, but do not specify separate deferral performance. In the case of openings, the test for the smoke performance exists at room temperature, but the smoke performance at high temperature is not secured, so countermeasures are needed.

  • This study of the vestibule of pressurizing smoke control system installed in domestic high-rise buildings for evacuation in case of fire, when the door is open to forming characteristics of the air flow was analyzed using fire dynamics simulator and analyzed of variance. Vestibule which is compartment of the design condition, air flow in the exhaust damper was formed severe turbulence confirming preceding research. The door position is in the range of formed vortex, unsteady flow of air occurs at the point that the door could be confirmed. According to the NFSC 501A, door to symmetrically separate the average of 10 points or more as measured from the average of wind speed to do is based. Under these conditions, it is difficult to measure the characteristics of the upper air flow of upper points. so measuring points are subdivided by more than 64 points method presented in TAB because severe deviation of wind speed.

  • This study is experimentally analyzed to extract the major parameters affecting the performance of the smoke-control system and the relations of pressure difference between vestibule and supply air pressure zone effect of supply mass flow rate and leakage area in the smoke-control zone. To obtain this, the mock-up building of three-story scale with a total of 10 compartments was constructed, and several apparatus were also installed for in-situ measurement of the ventilation flow rate, pressure difference between compartments, smoke defensive air velocity, the opening-closing force of door, etc. This article show that pressure difference in the smoke-control zone is significantly related with leakage area of vestibule in low pressure region, leakage area of supply air pressure in over pressure region and both of them in pressure control region when the pressure control range of damper is 45 Pa~55 Pa.

  • In the U.S., the pressurization of elevator shaft was developed in 1972 to allow vulnerable people, such as the elderly and weak who could not use escape stairs in case of fire, to evacuate. It is an advantage in terms of space saving by not using vertical ducts. This study drew the problem of the pressurization of elevator shaft based on the existing domestic patents and proposed improvements. The smoke control volume calculation method is proposed by using vertical modeling. Leakage gaps in elevator doors need to be reviewed through experimental data or actual data. The evacuation floor was divided, the openings in the elevator machine room were automatically closed to the fire signal and the relief damper was installed to improve the performance. The improved method functions as the smoke control damper supplying the air flow rather than maintaining the differential pressure. To increase reliability of the research results, the procedure was performed to verify by using Contam.
