You can model a bolted/twin pole in the Poles database by creating a new record, increasing the dimensions and strength of the corresponding single pole. Bolted poles are usually rectangular and the increased dimensions are obvious.

According to Busck the strength of a bolted pole is doubled in both directions. See section 9.1 in

Two poles with only a cross-arm between them ie not braced, have a capacity of twice a single pole in both longitudinal and transverse directions.
