摘要:
 结构试验目前尚未直接用于既有结构的评定.按照非破坏性试验的要求,对抗力和抗裂采用定态的试验方式,对挠度
和裂缝宽度采用定荷的试验方式.在这两种试验方式下,首先利用随机过程和条件概率的分析方法,确定单个试件抗力和作
用效应的概率分布,预测在试验不充分条件下单个试件的抗力和作用效应;然后依据各试件的概率预测结果,通过全概率分
析,推断抗力和作用效应的设计值,从而形成基于非破坏性试验的既有结构评定方法.该法较其他评定方法具有更为突出的
实证性和针对性.
Abstract:
At present, structural test is not directly used in the existing structural assessment. According to the requirements of
non-destructive test, this paper uses both the test mode of steady-state for resistance and anti-cracking and the test mode of
steady-load for deflection and crack width. Under the two test modes, firstly using the analysis methods of stochastic process and
conditional probability to determine the probability distribution of resistance and action effect of the single specimen to infer the final
resistance and action effect of single specimen under the test is not sufficient. Then based on the probability prediction results of each
specimen, the design-value of the resistance and action effect can be inferred through the full probability analysis. Thus the method
of existing structure evaluation based on non-destructive test was established, which is more empirical and targeted than other
methods.
