Moments are the product of force and distance relative to a point and induce rotational force. Moments can be applied to nodes or at a point along with a member. 非線形解析にはP-Deltaが含まれます, 場所, マグニチュード, 標識の方向を指定する必要があります. Moments that are applied at an angle to the node or member can be specified by providing the X, そして, モーメントの Z コンポーネント.
モーメントは、 “right-hand” grip rule. The sign convention is dependent on which axis the moment is applied to:
- Positive (+): Counter-Clockwise
- Negative (-): Clockwise
Moments applied to Nodes
To apply a point load on a node, の値を指定するだけです:
- メンバーがいます – The node where the moment is applied.
- Magnitude about X – Moment about the global X-axis.
- Magnitude about Y – Moment about the global Y-axis.
- Magnitude about Z – Moment about the global Z-axis.
- 負荷グループ – 荷重は、荷重グループ番号でグループ化できます. 次に、負荷グループに「負荷コンボ」の係数を掛けることができます。’ メニュー. オプション.
Here is an example of a 20kNm moment being applied to an end node looks like:
Moments applied to Members
To apply a point load on a member, の値を指定するだけです:
- メンバーID – The member where the point load is applied.
- Position Along Member – の % 位置 (from node A t B) along the member where the force is to be applied.
- Magnitude about X – The magnitude of the force in the global X-direction. Use negatives to specify the negative X direction.
- Magnitude about Y – The magnitude of the force in the global Y-direction. Use negatives to specify the negative Y direction.
- Magnitude about Z – The magnitude of the force in the global Z-direction. Use negatives to specify the negative Z direction.
- 負荷グループ – 荷重は、荷重グループ番号でグループ化できます. 次に、負荷グループに「負荷コンボ」の係数を掛けることができます。’ メニュー. オプション.
Here is an example of a 20kNm moment being applied to the middle of a member looks like:
