In order to analyze the aesthetic performance of cable dome structure,most existing cable dome forms were listed,their formal beauty was analyzed,and heptagonal serial cable dome structure and octagonal cable dome struc-ture were proposed according to the rules.Taking the structure of a pentagonal three-four-stay cable dome as an ex-ample,the static beauty of the structure in the static state and under the influence of the static beauty expression pa-rameters are analyzed.The influence of initial prestress on the dynamic performance of the pentagonal three-four-stay cable dome structure is discussed.Based on the method of static and dynamic beauty expression,the static state and load state of three examples of cable dome engineering are compared and analyzed.The results show that the circu-lar cable-dome structure itself is symmetrical with the stress state under the premise of satisfying the practical function and symmetrical load.In order to meet the needs of engineering and structural rigidity,the cable dome structure gradu-ally adopts rigid roof or rigid and flexible roof,which reflects the beauty of rigid and flexible cable dome structure.The results can provide reference for the unification of mechanics and aesthetics for the designers of cable dome structure.
