| 摘 要： | 根据对现存工业建筑可靠性鉴定的实践基础上,分析了目前我国工业建筑安全性、适用性、耐久性降低的主要原因和检测鉴定分析方法;特别对结构中混凝土强度的检测和计算方法进行了深入研究,提出了计算测区数量的公式和考虑样本容量大小结构中混凝土强度的计算公式;同时根据结构可靠度理论中相关性对结构体系可靠度的影响,提出体系可靠度的简化近似计算方法,并分析计算工业建筑单层排架结构体系的可靠度,在此基础上提出了单层排架结构体系可靠度的简化计算模式。

| Abstract: | On the basis of practice of assessing the reliability of existing industrial
structures, an analysis to the principal reasons of reduction of safety, the suitability and
the durability for industrial buildings is carried out. Method of checking, measuring and
identifying the structural reliability is presented as well. A special study is made to the
method of checking, the measuring and the calculating the concrete strength in
structures. Formulas for calculating number of measuring regions and concrete strength
in structures are proposed taking into account the sample size. An approximate method
is put forward to calculate structural system reliability with correlation effect for
single-storey industrial buildings. On the basis of calculated results, a simplified calcula-
ting model is given. |
