Bearing Plates...

The specification of bearing plates for bridges or prestressed concrete members is assigned by this function. If the effective width of a bearing plate is typed in, it will be used in calculating the available width of strut and verifying the bearing strength of concrete.

The vertical and horizontal plates support vertical and horizontal loads respectively. In the vertical plate, B, L, t, and are the width, longitudinal length, thickness, and slope (degree) measured from positive horizontal axis, respectively. If the plate is placed on top or bottom of a concrete member, Top or Bottom must be selected. In the horizontal plate, H, L, t, and are the height, longitudinal length, and thickness, and slope (degree) measured from … respectively. If the plate is placed at left or right of a concrete member, Left or Right must be selected.

Restraints...

The hinge or roller boundary conditions for the finite element analyses of plane solid and truss structures are assigned by this function.

Spring...

The stiffness values of springs in all directions are assigned to the elements modeling spring boundary conditions.

Strut Types...

The types of concrete struts defined earlier by DEFINE-Strut Types-Concrete Struts are assigned to the every element of a strut-tie model after clicking concrete struts one by one.

.

Tie Types...

The types of steel ties defined earlier are assigned to the every element of a strut-tie model. After conducting a finite element analysis of strut-tie model, the elements with tensile cross-sectional forces must be recognized as the steel ties.

Node Types...

The types of nodes defined earlier are assigned automatically to the every node of a strut-tie model.

Stability Check...

A constructed strut-tie model can be unstable during the finite element analysis. For this case, the element(s) with very small axial stiffness value(s) can be added to the constructed strut-tie model.

Element Check...

The elements whose strength verifications are not required can be assigned by this function.

Outer Element...

The boundary elements in a strut-tie model are assigned to the Outer Elements with available widths at elements’ both ends. The available widths at both ends must be assigned, too. The assigned available widths are used for determining the available widths of other elements.

Fixed Area...

The cross-sectional areas of certain elements can be fixed in the iterative process for determining the cross-sectional areas and forces of struts and ties.

Static Load...

The external loads in a strut-tie model are imposed by this function. Please refer to Quick Start-Application of Load.

Boundary Load To Truss Load...

The loads imposed to the finite element model of plane solid structure in the Beginning Mode are converted to the loads acting on the nodes of a corresponding strut-tie model. To activate this command, the elements and nodes of the strut-tie model must be selected first. The converted loads can be modified if necessary.
