OCL - masts with their parts
One cross-section of the overhead line - masts, the parts on them and their wires - calculated with the reference solver, the results in 3D.
OCL in the top bar opens OCL, when your licence plan includes it (Licence plans). OCL calculates one cross-section of the overhead line: one or more masts, the parts mounted on them - cantilevers, conductor holds, anchors - and the wires they carry. The loads come in by themselves: the self weight, the wires' tensions at the design temperatures, ice, snow and wind. The calculation runs on the server with the reference solver (The reference solver).
The list
The first page lists your company's cross-sections. New mast with a name starts a new one, a click on a name opens it, Delete removes one after asking.
The page
It is laid out like the other tools and fits the window; each column scrolls in its own box.
- Left - Input: the tree of the masts and their parts, Add mast, and below it the properties of what is picked.
- Middle - the window: two symbol tabs in its header, the model (to build it) and the results (once calculated); after them the toolbar with the views, fit, the settings of the results view and Calculate.
- Right - Results: after a calculation.
Building the model
- A mast: pick it in the tree or in the view. Its properties are the profile, the length, the position x and y, the foot level and Orientation: Strong axis across the track, Strong axis along the track or By angle in degrees. The profile and its faces turn together; a part's side stays in the track's terms.
- Add mast places another mast beside the last one.
- A part: click the mast in the view where it goes and choose the part - or choose it first and then click where it goes (Place). The face you click gives its side, the point its height.
- A part's properties: its height and side, its own inputs (from its part template) and each of its wires - Continuous with the spans before and after and the deviation, or Terminated. A cantilever's console is a part of its own: pick it to set its inputs; its length is always the offset it bridges.
- The delete symbol in the header of the properties removes the picked part or mast, after asking.
After a change the results say Outdated - recalculate: calculate again.
The results view
Calculate calculates every load case and combination and switches to the results tab. The upper left corner of the view says what it shows: the combination, the quantity and the value with its unit, and below each mast's profile and orientation.
- In the results panel, buttons choose the quantity - acting loads, forces, moments, stresses, deflections - and below them Combination and Value. Under these the panel lists what the combination consists of: its load cases with their factors, and those left out because they carry no load here.
- In the toolbar: the views (3D, front, side, top) and fit; On the deflected shape and 3D model with profiles as symbols, pressed while on; the Values on the diagrams (none, min / max, all) and, for deflections, the Direction.
- Click a support or an anchor to read its reactions in the combination shown. The deflected members are drawn curved, as they bend.
- The model tab brings back the building view; the results tab returns to the quantity you looked at last.
Moving the view is as in the 3D view (3D view): drag turns it about what you point at, shift+drag moves it, the wheel zooms.
The results panel
Warnings come first, then Foundations - the largest and smallest forces and moments at each foundation, each with its combination -, Anchors with the anchor's axial force, Members, Load totals per case and Notes.
Save keeps the cross-section together with its last result.
