摘要:

针对现行《工业建筑可靠性鉴定标准》(GB 50144—2008)仅能评定工业厂房的可靠性等级,无法计算其结构体系具体可靠指标的局限性,以既有单层工业厂房上部承重结构体系为研究对象,结合层次分析法的理论研究成果,确定了上部承重结构体系可靠指标的分级标准; 针对同类构件在安全性等级不同情况下结构体系承载功能的影响程度也存在差异的问题,提出构件等级权重比这一概念,并依据GB 50144—2008分别确定了不同安全性等级的重要构件和次要构件对应的权重系数; 最终提出了根据构件的类型、位置和安全性等级确定构件的权重系数,并结合构件可靠指标计算了单层工业厂房上部承重结构体系承载功能的可靠指标。将所提方法评定的结果与GB 50144—2008及灰色聚类分析评定的结果分别进行对比验证。结果表明:所提方法计算简单,能用具体的可靠指标反映结构承载工程的可靠性状态,可以满足工程应用的需要。

Abstract:

In view of the limitation that the current Standard for Appraisal of Reliability of Industrial Buildings and Structure(GB 50144—2008)can only assess the reliability grade of industrial workshops and can not calculate the specific reliability index of their structural system, the existing single-storey industrial building system was taken as the research object, and the theoretical research results of the analytic hierarchy process were combined to determine the reliability level. The classification criterion of reliability index of upper load-bearing structure system was determined. Aiming at the problem that the influence degree of bearing function of structure system of the same kind was different under different conditions of safety grade, the concept of component grade weight ratio was put forward, and the important components and secondary components of different safety grades were determined respectively according to GB 50144—2008. Finally, the weight coefficients of components were determined according to the types, locations and safety levels of components, and the reliability indexes of the load-bearing structure system of single-storey industrial buildings were calculated with the reliability indexes of components. The evaluation results of the proposed method were compared with those of GB 50144—2008 and grey cluster analysis. The results show that the proposed method is simple in calculation and can reflect the reliability state of the structural load-bearing engineering with specific reliability indicators, which can meet the needs of engineering applications.
