Analysis of a High-Strength Concrete Model under Biaxial Compression.

摘要

The behavior of a model of high-strength concrete consisting of nine coarse aggregate circular inclusions in a square mortar matrix is studied under biaxial compressive loads. Constitutive equations are developed following the theory of plasticity in order to describe the behavior of mortar in biaxial compression. The bond between mortar and aggregates is simulated by an interface element. A comparison of analytical and experimental results shows good agreement. (Author)
