Abstract Suspen-dome structures are widely used due to their superiority over traditional structures. The cable condition is crucial for the safety of the overall structures, especially the force in cables. However, to date, no accurate and efficient numerical method can be used for estimating the influence of friction. In this paper, a series of novel numerical methods were proposed and incorporated into a numerical model of the suspen-dome structure. The influence of friction on buckling capacity and dynamic response of suspen-dome structures was analyzed. Results indicated that the dynamic response is significantly influenced by friction. The numerical model that considers friction can be established efficiently in an overall structure model based on general finite element software and can be adopted for dynamic analysis. The buckling capacity can be maximized in the non-sliding condition. The fixation of the hoop cable located in the outer part of the structure has limited influence on the improvement of buckling capacity. For seismic analysis, the varying amplitude of cable force in non-sliding conditions was approximately two times that in sliding conditions.

摩擦对悬穹结构屈曲和动力行为的影响

摘要 悬穹顶结构因其优于传统结构而被广泛应用。缆索状况对整个结构的安全至关重要，尤其是缆索中的力。然而，迄今为止，还没有准确有效的数值方法可用于估计摩擦的影响。在本文中，提出了一系列新颖的数值方法并将其纳入悬穹结构的数值模型中。分析了摩擦对悬穹结构屈曲能力和动力响应的影响。结果表明动态响应受摩擦显着影响。在基于通用有限元软件的整体结构模型中，可以有效地建立考虑摩擦的数值模型，可用于动力分析。在非滑动条件下可以最大化屈曲能力。位于结构外部的环索的固定对屈曲能力的提高影响有限。对于地震分析，非滑动条件下索力的变化幅度大约是滑动条件下的两倍。
