The test results described in Part 1 of this paper (Lee and Bruneau, 2008) on twelve steel built-up laced members (BLMs) subjected to quasi-static loading are analyzed to provide better knowledge on their seismic behavior. Strength capacity of the BLM specimens is correlated with the strength predicted by the AISC LRFD Specifi cations. Assessments of hysteretic properties such as ductility capa...

At the initial stage of design, structural strength and stability load-bearing members aircraft are mainly considered. In this paper, a support assembly analyzed. First, analysis, under design load 30.151 KN, numerical analysis shows that, in stress concentration area, peak value is 571.9 Mpa. The experimental strain sensor S6 position compared with results, error within 2.5%, which verifies va...
