State-of-the-art qualitative simulators (for instance, QSIM) are known to be sound; no trajectory which is the solution of a concrete equation matching the input can be missing from the output.
Viscosity parameter ( mu ) is used for the visco-plastic regularization of the concrete constitutive equations in ABAQUS/Standard analyses.
(5) Viscosity parameter ( mu ) is used for the visco-plastic regularization of the concrete constitutive equations in ABAQUS/Standard analyses. .
(5) The viscosity parameter μ used for the visco-plastic regularization of the concrete constitutive equations in Abaqus/Standard was taken as 0.0005. .
From an applied perspective, the techniques used in [3] are interesting when applied to concrete difference equations, but additional difficulties appear, because among other things, we need to get explicit formulas for the solution of the equation to be studied.
In order to enhance robotization of concrete, general equations to predict the variations of the yield stress and plastic viscosity with time are proposed, using the corresponding mortar initial yield stress and plastic viscosity.
Stević also essentially triggered a systematic study of non-rational concrete difference equations and systems, from one side those obtained by using the translation operator (see, e.g., [16] and also [11]) and from the other side those obtained by using max-type operators (see, e.g., [17, 18, 27]), see also the related references cited therein.
For all categories that can be applied to a reaction, the algorithm then compiles a list of concrete kinetic equations.
The proposed equation is based on adopting the concrete contribution equation from the CSA S806-12 and modifying the stirrup contribution equation of the CSA A23.3-04 to reflect using FRP materials instead of steel.
It was observed that the concrete shear equation prediction could be improved if the concrete strength could be taken to a power value less than what is currently recommended in the guidelines.
