Abstract

Abstract: Water curtain system test was carried out for an outdoor wooden structure corridor.Combined with the special structure of the building, water curtain nozzles with different orientations are set. Through the comparison of two groups of ignition conditions, the changes of temperature and thermal radiation at different positions after the starting of water curtain are analyzed.The test results show that the starting of the water curtain system can effectively control the thermal radiation and smoke spread, and make the section behind the water curtain system being in a relatively safe state.The system can provide reference for the fire protection
design of similar projects.

Key words: wood structure, water curtain system, thermal radiation, smoke spread
