The proposed nonlinear elastic-viscoplastic model was implemented using the finite element software ABAQUS via a user-defined material subroutine, UMAT. Then, the accuracy of the model was verified by off-axis axial tensile and compressive creep tests. The …Author: Jiaxin Lv, Yi Xiao, Yun Zhou, Yuanhong Xie

Sep 06, 2017 · I would have thought no because my model has all the elements causing restraint built in and therefore knows how restrained the slab is. I have also read that a shrinkage restraint value of 20% should be used for completely restrained slabs. Using 20% instead of 100% for a completely restrained slab seems counter intuitive.

If the far end of a column is defined as a “roller” support (or both ends of the column are pinned) then the column does not provide any lateral restraint to the slab. Columns above the slab do not support the slab vertically, they can only restrain the slab rotationally and laterally.
