Thermoviscoelastic Analysis of Concrete Creep at Mesoscale [PDF]

open access: yesKey Engineering Materials, 2016
Concrete is a heterogeneous material made up at mesoscale of linear elastic aggregates distributed in a mortar matrix whose behavior is time and temperature dependent. The Interfacial Transition Zone (ITZ) between aggregates and matrix also influences the overall behavior.

Efficient Approximation Method for Concrete Creep Compliance Function

open access: yesYuanzineng kexue jishu
For concrete, the strain tends to grow when the stress is kept at a constant level. This phenomenon is usually referred to as creep. Creep is an important physical property of concrete.

Comparison of Creep Prediction Models for Self-Compacting and Conventional Concrete [PDF]

open access: yes, 2011
Realistic prediction of concrete creep is of crucial importance for durability and long-term serviceability of concrete structures. To date, research about the behaviour of self-compacting concrete (SCC) members, especially concerning the long-term ...

Creep of refractory concretes

open access: yes, 2018
Uniaxial compressive creep of a 90+% Al(,2)O(,3) and 50+% Al(,2)O(,3) refractory concrete was investigated. The creep behavior was evaluated as a function of aggregate packing, cement composition, and time at temperatures up to 2200(DEGREES)F and stresses up to 2500 psi;Refractory concrete crept more when heated the first time than on subsequent ...

Non-linear fire-resistance analysis of reinforced concrete beams [PDF]

open access: yes, 2003
The non-linear structural analysis of reinforced concrete beams in fire consists of three separate steps: (i) The estimation of the rise of surrounding air temperature due to fire; (ii) the determination of the distribution of the temperature within the ...

Experimental Study of the Creep Effect on the Mechanical Properties of Concrete

open access: yesAdvances in Civil Engineering, 2019
Available researches regarding the effect of a sustained load on concrete are limited and sometimes contradictory. In the specific context of prestressed concrete and more generally for all other concrete structures, the effect of creep on the residual ...

Creep and Shrinkage Self-Compacting Concrete (SCC) Analytical Models [PDF]

open access: yes, 2012
: In the structures whose long-term behavior should be monitored and controlled, creep and shrinkage effects have to be included precisely in the analysis and design procedures. Creep and shrinkage, vary with the constituent and mixtures proportions, and

Gardner&Lockman Model (2000) and its Application in Numerical Analysis of Composite Beams [PDF]

open access: yes, 2006
The paper presents analysis of the stress and deflections changes due to creep in statically determinate composite steel-concrete beam. On the basis of the theory of the viscoelastic body of Arutyunian–Trost-Bažant for determining the redistribution of ...
