The generally accepted procedures for designing lattice transmission towers in the US are those given in the American Society of Civil Engineers (ASCE) guide, Guide for Design of Steel Transmission Towers (ASCE Manual 52). When the ASCE Task Committee on updating Manual 52 was active prior to publishing the second edition, a topic of discussion and disagreement was the calculation of the strength of X-bracing members. The primary point of disagreement was the effect of the tension member load on the support offered to the compression member and how this should be accounted for in calculating the capacity of the compression member. To clarify the design of X-bracing, EPRI's Transmission Line Mechanical Research Center (TLMRC) initiated a research program to study the strength of X-bracing, with particular emphasis on the effect of the tension member load on the capacity of the compression member. A two-dimensional test frame was used to test X-braces constructed of equal leg angles, unequal leg angles framed either on the long le or on the short leg.
