摘　　要：为了对索穹顶结构的美学表现进行研究,列举现有的大多数索穹顶形式,分析其形式美,以五边形三四撑杆索穹顶结构为例,分析其在造型、建筑材料及其结构类型所涉及的比例参数影响下的静力美,探讨初始预应力大小对五边形三四撑杆索穹顶结构动力美表现的影响;根据静、动力美表现的研究方法对三个索穹顶工程实例进行静止状态与受荷状态的美学剖析。结果表明:结构在满足实用功能和对称荷载的前提下,圆形索穹顶结构本身与受力状态富有对称美。为满足工程需要以及结构刚度需求,索穹顶结构逐渐采用刚性屋面或刚柔性并存屋面,体现出索穹顶结构的刚柔并济之美。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.
