| Summary: | 碩士 === 中華大學 === 建築與都市計畫學系碩士班 === 102 === With exceptional and composite buildings rise in recent years. Hotels and department stores or commercial buildings are often used in large atrium building design. Because atrium building a special type of space. Using surround the most common configuration of the atrium space in the corridor (evacuation safety zoning space). So atrium building must be in accordance pick an empty floors area and number of floors for independent zoning regulations. Commonly used fireproof rolling door (with smoke detection linked) in divisions designed to prevent the spread of fire, effectively blocking plume dispersion.
Large atrium building using evacuation verification calculation in Taiwan. Because it does not use common evacuation verification calculation for smoke layer fall time, so it must rely on the Computer evacuation simulation smoke control or Computer evacuation simulation as a secondary assessment. Since May 2010 NIST published FDS subsidiary of Computer evacuation simulation, Fire Dynamics Simulator + Evacuation (FDS+Evac). Computer evacuation simulation of paper in Taiwan now rarely. Instruction and restrictions only refer to the operation manual of FDS+Evac, so it is must investigate effects on asylum directives factor.
The research firstly the use of fire evacuation verification calculation of "evacuation of assumptions" as the basis of simulated conditions. Institute of influential factors itemized evacuation instructions in FDS+Evac, proposed operation and limitations. Of which evacuation grid meshs and evacuation exit door width of the relationship between, and increasing obstacles have a certain influence on the evacuation. Finally the use of actual large atrium building on the FDS+Evac, and evacuation verification calculation for comparative analysis and coefficient of variation. Among evacuation verification calculation set to the same conditions and increasing obstructions simulated difference coefficient values close to evacuation verification calculation. Hope that results of this study can be used as future use in Computer evacuation simulation evaluation on the actual building of reference.
