| With the increasing span of the building, in order to meet the needs of lightingindoor, the application of glass skylights also increases. The support system of glassskylights is generally typical of large-span space structure, spatial structure is a high-profile structure, in which shell structure is nearly one of the fastest growing and mostwidely used spatial structure in half a century. Shell structure is a typical spatial structuresystem, the inherent mechanical properties. This shell structure has reasonable force,economic use of materials, beautiful shapes and diverse, and can cover a larger space, inrecent years, widely used in construction of a space structure. In order to increase thepermeability of the room and give a better visual effect, the use of quadrilateral meshonly in their additional tension within the cable structure in the form of flexible, effectivepermeability of this structure and the interior glass and easy processing. At present, theresearch on this is relatively little in our house, to provide a reference for future research,a more detailed analysis on this structure, the use of finite element analysis softwareANSYS, the finite element method.Mainly for a bit of research areas:1) Study the static analysis of the structure in use of ANSYS, mainly on theparameters of the structure to its carrying capacity (including cable cross-sectional area,initial cable stress, bar cross-section, long-span ratio and the span ratio).2) Study the vibration characteristics analysis of the structure, find the naturalfrequencies and mode shapes of the top20of the structure. Followed by the impact ofvarious parameters to its vibration characteristics (including cable cross-sectional area,initial cable stress, bar cross-section, long-span ratio and the span ratio).3) In use of ANSYS, study the transient dynamic analysis of structures (time-historyanalysis). Study the response of structure under earthquake and obtain seismic characteri-stics of the structure. |
