Creep of Anisotropic Clay: Microplane Model
Publisher: American Society of Civil Engineers
Abstract: Undrained constant‐volume creep of anisotropically consolidated specimens of clay is mathematically described by the microplane model, which is based on the assumption that the shear strain rates on the contact planes ...
Nonlinear Fracture Properties from Size Effect Tests
Publisher: American Society of Civil Engineers
Abstract: The previously derived size effect law for blunt fracture is exploited for determining the parameters of the R‐curve, of the crack band model, and of Hillerborg's fictitious crack model. No measurements of the crack length ...
Optimum Concrete Mixture Proportion Based on a Database Considering Regional Characteristics
Publisher: American Society of Civil Engineers
Abstract: This paper presents an enhanced design methodology for optimal mixture proportion of concrete composition with respect to accuracy in the case of using prediction models based on a limited database. In proposed methodology, ...
Cohesive Fracturing and Stresses Caused by Hydration Heat in Massive Concrete Wall
Publisher: American Society of Civil Engineers
Abstract: Avoidance of cracking damage due to hydration is an important objective in the design of nuclear reactor containments. Assessment of the safety against cracking requires a realistic material model and its effective numerical ...
Material Properties of Self-Flowing Concrete
Publisher: American Society of Civil Engineers
Abstract: In this study the properties of self-flowing concrete, in which flow was >600 mm, containing fly ash were experimentally investigated and compared with those of ordinary concrete. For five types of self-flowing concrete ...
