Influence of Spatial Variability of Tensile Strength on Seismic Cracking of Gravity Dam

工程科学与技术, 2019
Since the uneven construction quality and the inherent heterogeneity of concrete, the material properties of the gravity dam have spatial variability. The spatial variability of the concrete strength parameters will affect the seismic performance of dams,
