【摘要】 针对砌体结构房屋建立了结构可靠性评估指标体系。对子因素指标进行无量纲化处理,对传统的物元模型进行分析,提出一种改进的关联函数。考虑了构件的权重系数,提出了可拓指标,建立了以构件可靠性分析与整体结构可靠性可拓综合评判相结合的砌体结构房屋可靠性鉴定方法的框架。并通过工程实例证明该方法的可行性。更多还原

【Abstract】 A masonry structure reliability grading method based on extenics was developed. A revised correlation function was proposed by non-dimensionalization treatment of subsidiary factors and analysis on the traditional matter-element model. By considering the weight coefficients of the components,the extension indexes were but forward,by which the masonry structure reliability grading method for both the components and the massive structure was schemed. The feasibility of this method was proved by engineering examples.更多还原
