Diaphragms for lattice steel supports

Following a review of the available standards worldwide, it became obvious to the WG there was little definitive documentation addressing the application, design or requirement for horizontal diaphragms (plan bracing) within lattice steel supports.SC22 compiled a questionnaire concerning the design "rules" currently employed within the industry addressing its scope to self-supporting and guyed lattice steel supports. 21 responses were received and are published in this brochure.
