This paper describes the results of an experimental study to verify proposed design requirements for eccentrically braced frame links with hollow rectangular i.e., tubular cross sections. Twelve primary link specimens and two supplementary links that have different end connections are tested. Three cross sections and four normalized link lengths are considered. Two of the cross sections have we...

Abstract There are technical requirements for the assembly of thousands separate flange joints on radar panel. The use traditional manual has problems such as high labor intensity, low efficiency, and difficulty in uniform quality. Therefore, response to above problems, combined with precision joint position attitude, intelligent management control operation process, a set component system base...
