Abstract:With the recent trend in long span space structures, suspen-dome as a roof structure is becoming popular. Therefore, as the construction of long span structures increases in the world today, the effectiveness of suspen-dome structure should be considered in order to undertake further development of the system which may be required to improve its design and construction. One direction of the improvement of such structures is to seek new materials other than using the traditional steel to yield better results. This paper is a review of the suspen-dome system, including its characteristics, its use in space construction, its success as well as the possibility of replacing steel with other materials for better results. From the review, it is found that using steel cables in suspen-dome structure has some shortcomings which can be eliminated by the use of other materials. It is suggested that Carbon Fibre Reinforced Polymer (CFRP) can be the material because of its advantages over steel as indicated in the paper.

“…Midas Gen was used to establish the model and analyze the static as well asdynamic performance, while ABAQUS was used to analyze stability of the structure [7]. The maximum members, the maximum displacement, the maximum support reactions, the amount of steel and the stability of the structure were selected as the comparison parameters.…”

Introduction:For suspended-dome with big partial hole, two kinds of feasible plans were proposed. Method:One of the plans was to adjust suspended-dome's members, and another to build auxiliary supporting system to support the suspended-dome with columns together. These kinds of suspended-dome's main structural parameters include stiffness, member force, steel consumption, support reaction and stability, and parametric analysis is based on these parameters. Conclusion:Firstly,the scope of application was illustrated for the former plan. Then, an equivalent vertical stiffness algorithm was put forward for the latter plan. In the latter plan, limit stiffness constant was introduced to quantify the method for solving discontinuous support problem.

A radially retractable roof structure based on the concept of the suspen-dome is proposed in this paper. The radially foldable bar structure are strengthened by the lower cable-strut system. Then the buckling capacity of a radially retractable suspen-dome was investigated. The geometrically non-linear elastic buckling and elasto-plastic buckling analyses of the hybrid structure were carried out. Then the effects of different structural parameters, such as the rise-span ratio, beam section, area and pre-stress of lower cable-strut systems, on the failure load were investigated. The influence of imperfections on the elasto-plastic buckling loads was also discussed. The results show that the critical buckling load is reduced by taking account of material non-linearity. Furthermore, increasing the rise-to-span ratio or the cross-section area of steel beams notably improves the stability performance of the structure. However, the area and pre-stress of cable-strut systems pose small effect on the structural stability. It can also be found that the suspen-dome is highly imperfection sensitive and the reduction of the failure load due to imperfections is considerable.
