Abstract: In view of the large fire risk of timber structure buildings and the need for appropriate protection measures, comparison full-scale fire experiments of typical timber structure buildings were carried out to study the occurrence, development and spread characteristics of fire in the buildings. By comparing the changes of temperature, thermal radiation and building burn under different test conditions, the influence of fire retardant coating and other measures on preventing the rapid spread of fire in traditional timber structure buildings and enhancing the fire performance of buildings was discussed. The study is hoped to provide technical support for the follow-up fire risk assessment of traditional timber structure buildings and the corresponding suggestions on fire protection measures.

Key words: timber structure building, full-scale fire experiment, fire retardant coating
