Integrated Business Building Fire Evacuation And Structure Design Research

Comprehensive commercial building features:a large space, flammable, more people. These characteristics decided commercial building fire combustion characteristics:it is difficult to control, toxic and harmful gas emissions, personnel evacuation difficulty, fireproof structure design is very important. Commercial building fire hazards to human is the most direct, the most serious, commercial building often Chen Lieyou every kind of merchandise, the fire will bring huge economic losses; at the same time, interior flow is large, easy Qunsiqunshang calamity, the loss cannot be measured with money.At present the domestic fire evacuation and fire protection construction is mainly based on the code for fire prevention, fire prevention standard is aimed at universal building, comprehensive commercial building has its own particularity, for it cannot include the requirement of fire. The use of a performance-based fire design method to solve the comprehensive commercial building fire evacuation and fire protection structure design is feasible, also is the comprehensive commercial building fire protection design and development direction. With the continuous development of commercial buildings, the form and the function has its particularity. Not only in a single major. This gave the fire design brought no small challenge. Comprehensive commercial building fire safety design in city planning, architecture design, architecture, construction, HVAC, water supply and drainage, electrical and other aspects have special requirements, and are the major influence each other with each other, are indispensable. There is not a professional specializing in commercial building fire safety design, the strong technical tasks are often undertaken by architect, other professional support to complete, this disadvantage is the lack of fire protection design for the system and integrity, often fail to achieve the desired effect. Comprehensive commercial building whether in form or function, had the very big development, new material, new structure is often adopted, in order to achieve construction time, improve competitiveness. The traditional fire method has been unable to meet the present needs, often has lagged behind. Even restrict the development of commercial buildings.The aim of this paper is to fire safety evacuation, structure of the existing design method carries on the analysis and the summary, while the use of performance-based design method for evacuation and fire protection structure design, as can be seen by comparing the performance design makes up for some deficiencies of standard design.This paper finally gives comprehensive commercial building evacuation design and fireproof structure design method; and the use of performance based design concept for the design, compared to the existing design method, the comprehensive commercial building fire evacuation and fire protection design more scientific and reasonable, can basically meet the comprehensive commercial building safe evacuation and fireproof construction needs. Comprehensive commercial building fire evacuation and fire protection design, must follow the prevention first, combining the fire prevention and elimination" working guiding principle, combined with the actual requirement, fusion, uses the performance based fire safety design of the new thinking, for large comprehensive commercial building various business development and market fire characteristics, reasonable design, measures properly, based on the self protection and self, accomplish safe application, advanced technology, reasonable in economy. evacuation and fire protection structure design, as can be seen by comparing the performance design makes up for some deficiencies of standard design.
