Based On Numerical Simulation Means To Study Fire Risk Of Gansu Exhibit Center

In order to promote the development of Lanzhou city Gansu province area economic, improve the image and influence of city, Gansu province decides to establish Gansu exhibit center in Chengguan district in 2008. Gansu exhibit center east and west long 234 meter, south and north long 84 meter, build high 29. 5 meter. Bases prescribe of code for fire protection design of tall buildings 4. 3.1 bar, build high exceed 24 meter, extent exceed 150 meter, intercalate thorough architecture fire control driveway, press prescribe of code for fire protection design of tall buildings 6.1.7 bar, exhibit center apoapsis safety evacuate distance not answer 30 meter. Butthis exhibit center by way of satisfy big interspace use functional request, not press criterion to intercalate thorough architecture fire control driveway, build bosom cat not add anchor-hold exit satisfy evacuate distance of request too. Text use FDS numerical simulation means to Gansu exhibit center build engineering through fire hazard safety analyze, in existing of build design use numerical simulation means simulate fire happen and develop, get across to export result analyze, estimate architectural design if satisfy fire control anchor-hold request, assurer safely of personnel.Discourse first explain discourse inquisitive backdrop and meaning, secondly compare a few grow architecture fire smoke gas numerical simulation means, third mostly introduce FDS numerical simulation means correlation art base and use means, four built Gansu exhibit center FDS numerical simulation model, fifthly analyze to model export result , educe conclusion. Finally numerical simulation means apply foreground and future directions in architecture fire hazard safety analyze.
