Abstract: An experimental and analytical study on pore-water pressure occurring in the postpeak region of concrete due to the external load is performed to investigate the mechanism of water migration in concrete. In the experiment, ...

Abstract: A mathematical model for water migration in concrete that changes from a homogeneous to a nonhomogeneous material due to its loading history is developed in detail. In the proposed model, concrete is assumed to be composed ...

Abstract: The material parameters to express the degree of discontinuity of hydraulic gradient in the developed model (Part I) are calibrated based on the sensible analysis of the experimental results, and then the applicability of ...

Abstract: A mathematical model for water migration in concrete as a homogeneous material (one that does not contain cracks) is developed in detail. In the proposed model, concrete is assumed to be composed of aggregate, cement paste, ...

Abstract: An experimental and analytical study on pore-water pressure occurring in the prepeak region of concrete due to the external load is performed to investigate the mechanism of water migration in concrete. In the experiment, ...

Abstract: It is known that the consideration of tension stiffening effect resulting from bond slip between reinforcement and surrounding concrete is very effective for the deformation analysis of reinforced concrete members. In the ...

Abstract: Analytical formulation of constitutive equations for a single crack is made, which relates the shear and normal stresses to the corresponding displacements. The modeling of four basic coefficients involved in the constitutive ...

Abstract: Structural‐parameter identification of member properties of framed structures is conducted at the element level. By substructuring, a frame element is isolated from the complete structure, and the state equation used for ...

Abstract: An experiment was conducted to observe the real distribution of local microstrains at different orientations in the layers of mortar that separate aggregates in concrete material. The relationship between the microstrains ...

Abstract: One of the goals of this research is to apply nonlinear fracture mechanics to design problems encountered by the engineering society. Nonlinear fracture mechanics makes it possible to study the size effect with respect to ...
