Smoke control and extraction system in view of performance-based fire protection design for high speed railway station

Architectural design of high speed railway station in our country are more and more complex. Due to the limitation, current fire-protection codes cannot satisfy the actual project design, and the performance-based fire protection design is crucially important to solve the smoke control and extraction problem. According to the Shenzhen North Railway Station, presents the difficulty of smoke control and extraction system design, simulates the fire scene for the platform with upper cover and overhead waiting room respectively, and gives the smoke control and extraction measures based on the performance-based fire protection。
