混凝土结构时间多尺度环境作用研究
Temporal Multi-scale Environmental Actions for Concrete Structures
摘要
Abstract
Without considering the correlation in time and space for environmental actions, the features of time of environmental actions such as temperature and relative humidity were analyzed in detail on the basis of the characteristics of the " time calculation scale" for the representative value of environmental actions and the variation of environmental actions with time as well as an example about the carbonation of concrete due to the main environmental actions. It was found that the mean annual value and the adjusted mean annual value can be regarded as the representative value of environmental actions for the calculation of carbonation of concrete, and the Holt-Winters method can be used to describe the variation of the environmental actions well. Determining the appropriate "time calculation scale" and the variation of environmental actions with time? The carbonation depth of concrete structures can be predicted easily and precisely.关键词
