［摘要］上海天文館結(jié)構(gòu)形態(tài)復(fù)雜，為多種結(jié)構(gòu)體系組合成的一個整體，且各結(jié)構(gòu)體系包含多種結(jié)構(gòu)材料。其中，上部結(jié)構(gòu)包括大懸挑、大跨度、大開洞、不規(guī)則曲面等結(jié)構(gòu)單元，其地震作用下的響應(yīng)復(fù)雜，根據(jù)抗規(guī)屬于特別不規(guī)則結(jié)構(gòu)。結(jié)構(gòu)設(shè)計時通過采取合理的計算手段和抗震概念設(shè)計的方法，力求盡可能簡化各部位結(jié)構(gòu)體系，從而減小地震作用對結(jié)構(gòu)的不利影響，同時通過采取合理而有效的節(jié)點構(gòu)造，保證結(jié)構(gòu)各部位之間的連接安全有效，從而保證荷載在結(jié)構(gòu)上的有效傳遞。

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
