This section part can be used to make further definitions for bearing seats, which are generally used to fill the gap between girders utilized to define bearing seats between bearings and pier caps/abutments. Bearing seat definitions are only used for 3D models; thus, this section will not affect FEA. However, the definitions can be made to make the bridge models as similar to real-life bridges as possible. Bearing seats provide a stable surface for bearings to function effectively and can be used to reduce elevation differences between girders. Currently, bearing seats are mainly used for 3D models and 2D CAD. They do not affect FEM, except for potentially changing node elevations. Any stiffness due to the bearing seat is not modeled in FEM.

General

Insertion PointPoints: Used for specifying the bearing location and can be selected by using the three dots and the options ‘Pick...’ and ‘Select...’.

Width Computation : Width[User Input/Auto]: The options ‘Auto’ and ‘User Input’ can be chosen. In the case of choosing the ‘Auto’ option, the object will be generated according to the pier cap's width along Y-axis. Otherwise, the width of the object will be generated according to the input for the ‘Width’ column.

Width: If the ‘Width Computation’ parameter is set to ‘User Input,’ this column will be activated, allowing the user to specify the width of the bearing seat.

Length: The length of the bearing seat along the X-axis.

Horizontal Offset: When width computation is chosen as ‘User Input’, the horizontal offset value can be specified. This value indicates the distance from the center of the insertion point on the Y-axis direction.

Thickness Computation :Thickness[User Input/Auto]: The options ‘Auto’ and ‘User Input’ can be chosen. In the case of choosing the ‘Auto’ option, the object will be generated according to the distance between the top of the pier cap and the bottom of the girder. Otherwise, the thickness of the object will be generated according to the input for the ‘Thickness’ column.

Image RemovedThickness: If the ‘Thickness Computation’ parameter is set to ‘User Input,’ this column will be activated, allowing the user to specify the thickness of the bearing seat.
