ABSTRACT:

Construction sequence simulation analysis of a practical suspen-dome of Jinan Olympic Center is discussed in the present paper. Suspen-dome is a kind of advanced large-span space structure which is composed of an upper single-layer latticed shell and a lower cable-bar system. It is also a kind of hybrid system due to a combination of cable elements, bar elements and beam elements. Construction errors and temperature fluctuation are of importance and need to be taken into consideration during the construction process. The construction error of the structure is simulated by using the random imperfection modal method. Using the integral structure model including the concrete supporting system, the effect of the temperature variation on the suspen-dome is analyzed. The construction of suspen-dome is a little complex due to the interaction between the upper single-layer latticed shell and the lower cable-bar system. The configurations of the structure during the construction could be determined by an inverse analysis method or a mixed analysis method depending on the stages adopted in each construction scheme. And the influence to the lower cable-bar system caused by the setting-up errors at nodes is studied on the basis of one feasible construction scheme. Some meaningful and universal conclusions are given out.
