Abstract:The structural shape of Shanghai Planetarium is very complex. It is composed of kinds of structural system with different structural materials. Many structure elements are integrated in this project such as large cantilever, large span, large opening and irregular curved surface. The earthquake action response of the structure is very complicated and it belongs to especially irregular structure according to the seismic design code. Reasonable calculating means and seismic conceptual design method were adopted to simplify the structural system of each part of the structure in structural design to reduce the detrimental effect of the earthquake action on the structure accordingly. Reasonable and effective joint structures were adopted to make the connection between structure elements safe and reliable to ensure the effective load transfer on the structure.

Keywords:Shanghai Planetarium; seismic design; cantilever structure; steel shell structure; concrete shell structure; aluminum structure
