Tower Design Guides

Practical, code-based engineering notes on designing and analysing lattice communication towers to Indian standards — IS 875, IS 17740 and IS 800.

Pillar guide

How to Design a Lattice Communication Tower to IS 17740:2022

The full workflow, start to finish: tower configuration, loads (wind, antennas, seismic, ice), load combinations, 3D analysis, member capacity, bracing, connections and serviceability.

Member Capacity & KL/r Slenderness for Tower Members

How each member is checked: tension yield, Perry-Robertson compression buckling, IS 800 buckling curves, per-role KL/r limits, IS 17740 Annex F equivalent slenderness and the X-brace out-of-plane trap.
