| 中文摘要: |
| 超高层建筑人员疏散效率直接影响建筑安全水平。基于模糊层次分析法(FAHP),构建了评价超高层建筑疏散效率的指标体系,分析了各因素对疏散效率的影响。结果表明疏散宽度和人员数量对疏散效率影响较大。通过人员疏散软件对评估结果进行了验证。疏散效率结果与人员疏散模拟软件的计算结果基本吻合,能较准确地预测各因素变化所带来的影响,但对于人员数量较少时疏散宽度发生变化的情况尚不能完全适用。 |
| 英文摘要: |
| Evacuation efficiency affects the safety level of high-rise buildings.Based on fuzzy analytic hierarchy process,a hierarchical index structure was established for accessing evacuation efficiency of a high-rise building,and the effects of index on evacuation efficiency were analyzed.The results revealed that the exit width and the number of people are two main influencing factors for evacuation efficiency.The results were verified by comparison with evacuation simulation results.Evacuation efficiency obtained from the analysis agreed well with the simulation results,and the effect of index changing was also correctly predicted.However,the method cannot apply to the situation where the exit width varies while with small number of people. |
