What restraints can be added using the “Add Restraint” tool in ADAPT-ABI?
In ADAPT-ABI, the user may specify the restraints or the program creates them automatically. In locations where several nodes occur (i.e. connections), the program may have difficulty in correctly assigning restraints between piers and cells.
To delete, modify or replace an automatically generated restraint, go to the developed view to delete an existing restraint, modify an existing restraint or add a new restraint. You can double click on any restraint to bring up the properties box for editing.
As an example you can allow Z Translation and Y Rotation free while X Translation will follow the master, resembling R=3,0,0. The following are possible restraints:
R = 3,0,0; X translation follows master, Y rotation free, Z translation free.
R = 3,0,3; X translation follows master, Y rotation free, Z translation follows master.
R = 3,3,3; Y translation, Y rotation and Z translation follow master.
R = 0,3,3; X translation free, Y rotation and Z translation follow master.
R = 0,0,3; X translation free, Y rotation free and Z translation follows master.
R = 0,0,0; X translation, Y rotation and Z translation free.
Other cases are not allowed when the nodes are not located at same location. As an example “11 R=0,3,0 M10” is intended for a hinge, thus a nodal hinge should be created in lieu of a restraint. Similarly, “50 R=3,3,0 M49” is possible when you use a nodal hinge. Double clicking on “Add Node Hinge” will allow for the same input functionality as a Restraint.
