Abstract:Special-shaped steel structures in China are developed rapidly. Taking the entrance lobby of a project in Shanghai as the engineering object, a series of studies and analyses were carried out in view of the particularly irregular situations such as the obvious torsional effect, lots of missing floor slabs, lots of inclined columns, skip-floor columns and special-shaped roofs, in order to prove the rationality and practicability of the structure design. The structural layout of the entrance lobby and the measures taken for irregular situation were introduced. Two different software（YJK, MIDAS Gen） were used to carry out the comparative analysis of the structural elasticity under frequent earthquakes, and the checking calculation of key components was conducted under fortification earthquakes. The elastic time-history analysis and static elastic-plastic analysis of the whole structure were carried out. The elasticity analysis of the slab was conducted under frequent earthquake and non-yielding analysis of the slab under fortification earthquake was carried out. The ultimate bearing capacity of the special-shaped roof system was carried out by using ANSYS finite element software. The above analysis effectively ensured the overall safety of the structure and provided a reference for the structural design of similar projects.

Keywords:particularly irregular structure; steel arch beam; inclined column; elastic time-history analysis; static elastoplastic analysis; ultimate bearing capacity
