Spun concrete pole design
Design tapered spun reinforced-concrete poles end to end in your browser, powered by the fiber section engine. Capacity is checked at stations along the pole under different loads, and the longitudinal and stirrup zones are optimized along the height. A detailed PDF report is produced, and concrete and steel takeoffs plus fabrication detail drawings are generated ready for production.
Automatic design at stations
Required-capacity calculation, automatic design and existing-reinforcement checks at every level of the tapered pole.
Zone-based optimization
Set the longitudinal and stirrup zones independently for buildability and economy. Rebar laps and cuts are determined automatically.
Single- or double-wrap spiral stirrups
Use single- or double-wrap spiral stirrups at any pitch for buildability and increased shear/torsion capacity.
Detailed steel & concrete takeoff
Automatic bar-marking with a detailed reinforcement takeoff and the total concrete volume.
Fabrication drawing & work order
Pole elevation, developed reinforcement layouts, section drawings and a takeoff table are laid out on a print-ready sheet as a fabrication form, generated automatically. Downloadable as DXF.
Formula- and code-referenced reports
Design checks are shown with explicit formulas and code references — in the interface, in the PDF report and in the calculation's digital publication — making verification and review easy.
Questions
- What is a spun concrete pole?
- A spun (centrifugally cast) concrete pole is a structural column made by spinning high-quality concrete and steel reinforcement in a mould at high speed, so centrifugal force compacts it. The result is a hollow, circular section with an extremely smooth, durable outer surface. Spinning drives out voids and excess water, giving the pole high compressive strength and excellent resistance to the elements. Spun poles are widely used in electricity transmission and distribution lines (LV/MV), lighting systems and power lines. StructuralMind automatically prepares the design, calculation reports and detail drawings for these poles.
- What does reinforcement and stirrup zone optimization achieve?
- Because the pole is tapered, using a single layout with the same bar count and diameter along the whole pole is uneconomical — and the bars may not fit the section as it narrows toward the top. Reinforcement and stirrup demand also differ along the pole. So StructuralMind computes the required capacity at stations using the real section, but keeps constant, symmetric reinforcement and stirrups within the zones you define and computes laps automatically. Where lengths exceed a bar's cut length, cuts and laps are added automatically. This balances buildability and economy to reach the optimum solution.
- Do I get a fabrication drawing?
- Yes. The pole elevation, developed reinforcement layouts, section drawings and takeoff table are laid out on a print-ready sheet as a fabrication form, generated automatically. It can be downloaded as DXF.
