The convention class building belongs to the big spatial structure,to use the new material,the new technology,the imposing manner to be grand massively,the function is complex.If our country has completed the convention class building has Beijing new country exhibition,Beijing publication physical distribution center,Chengdu century city new international convention center,the Zhengzhou international convention center and so on.However,as a result of convention class building particularity for example:Population indefinite,when cloth exhibition has the massive combustible substance,to manage the exhibition unit to be changeable,management difficulty big and so on,this kind of building's fire protection design use convention's fire protection standard also already exposed more and more flaws,how safe and reasonable carries on the fire protection to this kind of building to design into present's focal point question.The performance fire protection design is one kind of new fire protection system design mentality,is the establishment in the more rational condition one new design method.It is not according to definite,the irrevocable pattern carries on the design,but first formulates the performance goal which using the fire safety engineering's principle and the method the entire fire protection system should achieve,and aims at each kind of building's actual condition,application all possible methods to go to the consequence which and will cause to the construction fire risk to carry on qualitative, the quota forecast and the appraisal,obtains the best fire protection design proposal by the time and the best fire protection.As one new guarantee building fire protection security's design method,the performance design widely was already used by many countries,uses the performance design method in our country also to become ultimately.This article main research content is as follows:the harm which and the steel products temperature rise influence:(1) based on the convention class building's function and the characteristic,through analyzes when fire word it produces,needs some basic parameters and the theory according to the performance fire protection project analysis,and unifies our country convention class building the development,pointed out that the existing project example the question which meets in the conventional fire protection design,thus obtains convention class building the performance design procedure and the process.The performance design has manifested his scientific nature,the security and the efficiency in this kind of building.(2) this article rests on the structure fire protection performance design theory, through the analysis biggest fire load situation in the steel structure component's temperature change,specifically protected from fire the example to analyze the component to take the different fire precautions under the different temperature rise, thus,will propose the proper attention to both security and the economical artistic steel structure fire protection plan target-oriented.(3) in the structural fire precaution safe design,the scattered question is also very important,when its immediate influence fire,personnel,commodity safety and rapid shift.This article applies the FDS finite element software to the example,in the analysis biggest fire load situation,in the convention class building the temperature field distribution situation,as well as the haze density,the noxious gas density distributed situation,provides the effective theory basis for this kind of building performance fire protection design.
