The Zhengzhou 27 Subway Station Under Fire Smoke Control Multiple Ventilation Mechanism Perfect Research

“…A subway station in Guangzhou as an example, consider the design according to the 2023, the early peak hour traffic of 15 thousand people, the station hall and video rate decreased for 120s within the range of 80 m did not escape the combustion zone personnel is dangerous [10], but the evacuation speed is 1.3 m/s and 80 m within the scope of the staff the escape time is only about 60s, so the automatic sprinkler system is feasible. Set the automatic sprinkler system can significantly reduce the ignition point temperature, so the heat is "average" assigned to the other position of the tunnel area, which the lag time of about 150s, for the trapped escape from the fire; automatic sprinkler system is set up [11], so that heat is not concentrated at the top of the tunnel damage accumulation at the top the strength of the concrete structure, so as to protect the tunnel structure, so the installation of automatic sprinkling fire extinguishing system in metro tunnel can improve the safety and reliability of [12].…”

“…According to statistics, the average daily passenger volume of Moscow Metro reached 8 million passengers, ranking first in the world, and the daily average passenger flow of Beijing Metro reached 1 million 250 thousand. Therefore, it is very difficult to organize evacuation in a fire accident [2]. (2) fewer ways to escape.…”

Prediction of Temperature Distribution to Evaluate Axial Strength of Unprotected Concrete-filled Steel Tubular Columns under Fire

“…무피복 CFT 기둥의 화재 시 내화성능 및 거동에 대한 연 구는 여러 연구자들에 의해 수행되었으며 이들에 의하면 CFT 기둥의 내화성능을 결정하는 주요 변수는 하중, 단면크 기 및 형상, 강관의 두께, 유효좌굴길이, 콘크리트 강도 등인 것으로 알려져 있다(Lie 등 [6] , Kodur [7] , Wang [4] ). Table 1.…”

Heat transfer and structural response modelling of FRP confined rectangular concrete columns in fire

“…1. An explicit finite difference method was used to treat the heat transfer analysis within the column, since a similar technique has been widely and successfully used in the past for modelling conventional reinforced concrete structures [3,4,5,6,7], as well as FRP strengthened reinforced concrete structures [1,8]. The model for structural behaviour in fire employs a two-dimensional fibreelement analysis and invokes the Column Deflection Curve Method originally proposed by Chen and Atsuta [9].…”
