According to the practical engineering application, the reasonable effective lengths of compressed chords and braces are presented. In the end, the static behavior of multiplanar XX-joints are discussed, which used widely in practical engineering. An amount of joints with the variable joint parameters under lode-case are analyzed. Base on research achievement of uniplanar X-joints, a set of formula is proposed to predict the ultimate bearing capacity of multiplanar XX-joints, which are easy to understand in physical concept and simple in practice.
