Prediction of Freeze-Thaw Life of Existing Masonry by Bayesian Method
In order to explore the freeze-thaw durability life of masonry,a durability model of freeze-thaw damage of masonry materials was established with the strength loss rate as the damage index,the reliability index of durability damage was calculated.The freeze-thaw damage durability grade of masonry materials was divided by reliable indicators,and the prior durability life prediction curves of each grade were calculated,and the prediction curves were updated by Bayesian method based on the detection information.The results show that the posterior prediction model combines the prior information and the detection information,and the prediction results are reasonable.
