Describes a basis for assessing the strength of members and connections for towers of lattice construction consisting of bolted, riveted or welded steel angle or tubular sections. The recommendations supplied are valid for both equal and unequal angles, either rolled or cold formed, compound members fabricated from these sections and tubular members.
