Modeling curved and spiral members in SkyCiv Structural 3D
Curved Members
SkyCiv provides a number of advanced operations to speed up your modeling workflow.
「曲がったメンバー」’ operation allows you to select (2) ノードとアークを生成する (メンバーで構成された) それらの間の. この機能は、湾曲した梁やアーチなどの湾曲した構造をモデル化する場合に便利です.
例: Modelling a curved beam
この例では, 曲がった梁をモデル化します. The first step is to create two nodes. Use coordinates (0,0,0) そして (10,0,0) meaning that our two nodes are separated by 10 ft in the x-direction.
- Number of Members – The number of members used to make the curvature.
- Section ID for the Members – The cross-section ID applied to each member.
- 半径 – The radius of the curve between the two nodes. The minimum value of the radius is half the distance between the nodes
- Plane – Which coordinate plane the curve will be generated in.
- 方向 – Positive or Negative, affects which direction the curve “travels”
例えば, 我々は使用するだろう 20 members to make up a curve (the more members, the more accurately the curve is represented and vice versa). For the radius, the minimum value is the half distance between the two nodes. Since the two nodes in this example are separated by 10 フィート, the minimum half distance is 5 フィート. A value higher than the minimum for the radius will result in a ‘flatter’ 曲線. You can also directly specify section ID for the members of the curve to assign them a particular cross-section. Plane options (XY-plane, XZ-plane) and direction (positive, ネガティブ) can also be specified.
スパイラルメンバー
The ‘Spiral Member’ operation allows you to select one node as the starting point, and generate a spiral (メンバーで構成された). This feature is useful when modeling spiral structures like some types of staircases or railings.
例: Modelling a spiral structure
この例では, we will model a spiral structure. The first step is to a node at the origin (0,0,0).
Select the node by clicking it. 選択時, the node will turn blue.
Go to the top toolbar, その後 編集する > 操作 > スパイラルメンバー.
A popup will appear to give you some options.
- Total Number of Members to Use – The number of members making up the spiral structure.
- Section ID for the Members – The cross-section ID applied to each member.
- Helix Base Point Center Point – The center of the helix structure. Enter x, そして, z coordinate.
- Helix Length – The length between the turns, in the propagation direction.
- の数 360 degree turns – The number of complete turns.
- 方向 – The spiral propagation direction.
- Turning Direction – The direction that the spiral will turn in (clockwise / counterclockwise) as it propagates in a particular direction.
The generated spiral structure is shown below.
