Study On Performance-based Fire Protection Design Of Wholesale Market

With the development of society and the improvement of living standard of the people, a lot of high-rise buildings and large-scale commercial buildings have emerged in our country. The present prescriptive fire protection design code can't well guide the fire protection of those buildings to design. To the question, at present, we use performance-based fire safety design method solved the normal deficiency of "prescriptive fire protection design code" both at home and abroad, in order to meet society's and economical development.Because of the characteristics of large personal density, heavy fire load, if fire is taking place, there will cause the enormous losses of the property, a large amount of injuries and deaths of personnel's. Based on investigating on wholesale market of Xi'an ,mastering wholesale market commercial situation of building at present. The author utilize performance fire prevention design method to analysis those buildings and calculate parameters according to data which investigate, making the contras with norm to carry on performance-based fire safety design.The main purpose of investigating is to study the problem of evacuate in commercial architecture. The content that mainly involved is as follows, design the fire load, establish the fire scene, the hot release rate (HRR), the application of FDS, Japan empirical formula, etc. Thus we will Analysis the state of fire development, movement situation of exhaust gas and distribution of indoor temperature, etc. We will assess insufficient of prescriptive fire protection design code with performance-based fire safety design method.It is important meaning to reduce the casualties, to reduce loss of property, to safeguard the social stability, to protect the environment, to ensure economic development, etc. After fire prevention design and Appraisal, we will raise the rationality of fire protection investment to the wholesale market commercial construction , enhance the floor space utilization ratio, enhancs the fire protection synthesis safety level of wholesale market commercial construction, obviously enhance the economic efficiency and the social efficiency of wholesale market.
