Node Restraints

Function: This function is used to define the support conditions and degrees of freedom at selected nodes in the structural model. Purpose: To establish the boundary conditions that simulate how the structure connects to its foundations or other supporting elements. Proper restraint assignment is essential for accurate structural analysis, as it directly influences load transfer, deformation behavior, and internal force distribution. Operation: For each selected node, specify the translational (Tx, Ty, Tz) and rotational (Rx, Ry, Rz) restraints by checking the corresponding boxes. Define spring stiffness values (Kx, Ky, Kz, Cx, Cy, Cz) where applicable for elastic supports. Additionally, specify any eccentricities (dx, dy, dz) between the node and the actual support location if needed.
