摘要
为合理确定震后地震现场安全鉴定时建筑物整体震损各影响因素的重要程度,通过层次分析法(analytic hierarchy process,AHP)研究了各影响因素的权重系数。详细介绍了层次分析法的计算步骤,并举例计算出了单层钢筋混凝土柱厂房震损各影响因素的权重。结果表明:AHP法计算过程简洁、计算结果精确;AHP法处理复杂系统问题时,每个影响因素的影响均可以定量化,非常清晰、明确;AHP法能把定性方法与定量方法有机地结合起来,使复杂系统分解。可见应用AHP法来确定单层钢筋混凝土柱厂房震损各影响因素的权重系数是非常合理和准确的。因此,在确定其他类型结构整体震损各影响因素权重系数时,也可以参考应用AHP法。
In order to reasonably determine the importance of the factors affecting the overall earthquake damage of buildings during the on-site safety evaluation after earthquake,analytic hierarchy process(AHP)was used to investigate the weight coefficients of the factors.The calculation procedure of AHP method was introduced in detail,and the weight of each influencing factor of earthquake damage of single-story reinforced concrete column workshop was calculated by example.It is shown that AHP method is simple and accurate.When AHP is used to deal with complex system problems,the influence of each influencing factor is quantifiable and very clear.AHP method can combine qualitative method and quantitative method organically to decompose complex system.It is concluded that the AHP method is very reasonable and accurate to determine the weight coefficients of the factors affecting the earthquake damage of single-story reinforced concrete column workshop.Therefore,AHP method can also be used as a reference when determining the weight coefficients of the influencing factors of the overall seismic loss of other types of structures.
