Nodal Load tab

Used to apply nodal loads.

The following options are available under this tab:

Node

設定説明
Fx/Fx', Fy/Fy', Fz/Fz' Type values of the forces in corresponding global directions or inclined axis (') directions when the Inclined Load? option is checked. A negative sign (-) may be used.
Mx/Mx', My/My', Mz/Mz' Type values of the moments about the corresponding global directions or inclined axis (') directions when the Inclined Load? option is checked. A negative sign (-) may be used.
Inclined Load? Check this option to specify the load along an inclined coordinate system. An inclined coordinate system is defined by an X' axis that pass from the loaded joint through a reference point. That reference point can be defined either a reference node, a set of absolute (global) coordinates, or a set of relative distances from the loaded joint.
注記: When this option is checked, the load vector labels are updated to reflect the inclined (') vector.
Inclination Select the option used to define the inclined coordinate system.
  • Reference Node - select an existing node number from the model. The global coordinates of that node are displayed as read-only.
  • Absolute - type the global coordinates of an arbitrary point to use as the reference.
  • Relative - type relative distances from the loaded joint to the reference point. These distances are measured along the global axes.

参照点は、絶対座標、相対距離、参照ジョイントのいずれを使用して指定した場合も、荷重ノードから参照点へのx'軸の方向を定義します。Y'軸の方向は、X'とYの平面上のx'に垂直な方向として定義されます。X'がYの方向にある特殊なケースでは、Y'はZの方向になります。Z'の方向は、X'とY'の平面に垂直な方向として定義され、STAAD.Proで使用される他のすべての座標軸系と同様に右手系の規則に従います。

Support Displacement

Used to specify a support displacement. Multiple support displacements may be used for a single load case, but each support value and direction must be entered independently.

設定説明
Displacement Specify the value of the displacement. A negative sign (-) may be used.
Direction Select the direction of the displacement as Fx, Fy, or Fz (translational), or Mx, My, or Mz (rotational).
