| There are lots of forms in space reticulated shell structure. Reticulated Shell forms are properly chosen according to idiographic conditions of projects in the engineering applied,which is the key of structure designing. This is because many aspects,such as space structure technically targets,doing and fitting qulitly,and building plan, etc. are affected by shell forms.To large span space structure this is very important.This dissertation combination with mechanical behaviors and structure feature of Reticulated Shell Structure and Frame Arch Structure. Through dispose dragline and prestressed in FrameArch Structure ,we developed a new type space hybridize structure------PrestressedArch-supported Reticulated Shell Structures.It is a special kind of structure of Arch-supported Reticulated Shell Structures. The structure not only holds the advantages of Reticulated Shell Structure but also remedies disadvantages of Prestressed Frame Arch.In-depth theorical analysis and proof trail have been made to the new hybridize structure in this research program. At the same time ,the definite element calculating and analysis method is introduced. At the same time, we achieved stability analysis of the model in ANSYS. Represented the statics force character and other character between Prestressed Arch-supported Reticulated Shell Structures,we summarized the date with a great deal of iconograph and table.As theorical analysis above, this new hybridize structure behaves much better combined with Reticulated Shell Structures and Prestressed Frame Arch. It has better capability of holistic load and better seismic fortification. Because of these advantages, the new hybridize structure should be worth applying to large span structures. |
