The Analysis Of Performance-based Fire Engineering Design Method For Xinxin International Square In Shenyang

With the fast development of social economy and quiet great progress of architectural technology, in large cities, especially in economically advanced cities, large-size public building with the new design concept and structure style comes forth continuously. It becomes the feature sign of the construction and development of the city. It takes some difficulties to fire design because of the fast progress of the large-size public building: it is difficult to the large-size public building with large space to adopt some effective fire security measures of general buildings because of the particularity of building structure and the demand of serviceability; when fire happens, the character and phenomenon of the large-size public building are different with those of general buildings.At present, building fire prevention design of our country mainly depends on all kinds of managerial norms of fire technology. Those norms were set down by referring to the fire technology norms of the developed countries, absorbing definite experimental achievement and combining the specific situation of our country. On the foundation of generalizing the past hands-on and fire lessons, the given design parameter and index of norm were confirmed, which should be scientific and rational. However, security escape of the large-size public building becomes the emphasis and the difficulty of all countries in the world because the new structure, the new technology and the new material are generally used in the large-size public building. If simply to design according to the current fire norm in which the design parameter and the index are cardinal, there are a lots of problems to be solved in its science, rationality and economy. Therefore, the new fire design method, performance-based fire engineering design method, should be applied to the large-size public building.Performance-based fire engineering design method is a new building fire design method that bases on security engineering of fire control. It utilizing the principle and the means of the security engineering of fire control, according to the specific conditions including the structure, purpose and internal inflammable matter of the building and the different spacial condition, functional condition and other correlated condition, designer can freely select all kinds of fire precaution measure in order to obtain the aim of fire security and reasonably combine those factors. Then, integral fire security design scheme can be composed. Using the developed engineering method, the fire risk and the fire harmfulness of the building can be quantitatively...
