Abstract
Abstract A truss structure comprising spaced first and second channel members and an undulating truss member between the first and second members. The undulating truss member comprises a strip of substantially uniformly thick material having a greater width than thickness and having alternately first and second apices interconnected by struts or leg members, each apex being in the form of a substantially single line and being secured to the channel members. The struts have generally U-shaped cross sections which are symmetrical about the plane containing the apices of the struts and have a base that increases in width from the center of the strut toward each of the apices and walls that decrease progressively in height from the center of the strut toward each of the apices.
