CREEP RATE IN CONCRETE 337 Discussion on the Proposed Creep Law
Despite decades of intensive research, an entirely satisfactory constitutive relation for creep in concrete is still unavailable, even for working stress levels [I]. The rate-type creep laws with internal variables [2], although rather effective for numerical creep analysis of large structural systems, seem to be incapable of describing the aging phenomena without at least partially violating s...
متن کاملUnified Formulation for a Triaxial Elastoplastic Constitutive Law for Concrete
A constitutive model to describe the triaxial load-response spectrum of plain concrete in both tension and shear was developed. The inelastic phenomena are described using the plastic flow with direction determined by the gradient of the plastic potential. A new plastic potential is introduced and experimentally fitted to ensure better estimate of the load direction. This approach allows to con...
متن کاملDrying creep of concrete: constitutive model and new experiments separating its mechanisms
A new experimental method which allows the direct separation of the components of drying creep due to micro cracking and stress-induced shrinkage is developed, demonstrated and validated. The hasic idea is to compare the curL'CIture creep of heams suhjected to the same hending moment hut rery different axial forces. The results confirm that drying creep has two different sources: microcracking ...
متن کاملConstitutive Law and Flow Mechanism in Diamond Deformation
Constitutive laws and crystal plasticity in diamond deformation have been the subjects of substantial interest since synthetic diamond was made in 1950's. To date, however, little is known quantitatively regarding its brittle-ductile properties and yield strength at high temperatures. Here we report, for the first time, the strain-stress constitutive relations and experimental demonstration of ...
متن کاملNanogranular origin of concrete creep.
Concrete, the solid that forms at room temperature from mixing Portland cement with water, sand, and aggregates, suffers from time-dependent deformation under load. This creep occurs at a rate that deteriorates the durability and truncates the lifespan of concrete structures. However, despite decades of research, the origin of concrete creep remains unknown. Here, we measure the in situ creep b...
