Abstract:The inspection hall of Qingdao Cruise Terminal adopts large-span steel structure roof, and its horizontal projection is the shape of rectangular with the major axis length of 324m and the short axis length of 92-5m. The design conditions for the steel structure of the inspection hall were introduced and some key technical difficulties and solutions were highlighted including abnormal shaped and variable cross-section simulation and determination of calculated length. The results show that it is a kind of high precision method to simulate the abnormal shaped and variable cross-section by using the subsection input method. The buckling analysis is a simple and effective method to determine the calculated length of the structure composed of the same rigid frame unit. The joint stiffening plate has obvious effect on improving the stress concentration of the joint.

Keywords:large-span steel structure; abnormal shaped and variable cross-section; buckling analysis; finite element analysis
