Abstract:
The fuzzy comfortability of a wind‑sensitive super‑high tower crane is critical to guarantee occupant health and improve construction efficiency. Therefore, the wind‑resistant fuzzy comfortability of a super‑high tower crane in the Ma’anshan Yangtze River (MYR) Bridge site is analyzed in this paper. First, the membership function model that represents fuzzy comfortability is introduced in the probability density evolution method (PDEM). Second, based on Fechner’s law, the membership function curves are constructed according to three acceleration thresholds in ISO 2631. Then, the fuzzy comfortability for the super‑high tower crane under stochastic wind loads is assessed on the basis of different cut‑set levels λ. Results show that the comfortability is over 0.9 under the required maximum operating wind velocity. The low sensitivity to λ can be observed in the reliability curves of ISO Ⅱ and Ⅲ membership functions. The reliability of the ISO Ⅰ membership function is not sensitive to λ when λ < 0.7, whereas it becomes sensitive to λ when λ > 0.7.
为保障施工人员健康和提高施工效率，需要对超高塔吊的施工舒适性能进行精细评估。因此，本文以马鞍山公铁长江大桥为工程背景，通过将隶属度函数引入概率密度演化理论中，建立了超高塔吊风振模糊舒适度评估方法。基于Fechner定律，给出了ISO 2631中3类不同加速度限值下的隶属度函数曲线。在此基础上，通过λundefinedundefined‑截集技术实现了超高塔吊的风振模糊舒适度评估。结果表明，在规范允许最大施工风速下，超高塔吊的模糊舒适度大于0.9，满足施工舒适度要求。基于ISO Ⅱ和ISO Ⅲ隶属度函数的舒适度对λundefinedundefined的敏感性较弱。基于ISO Ⅰ隶属度函数的舒适度在λundefinedundefined<0.7时对λundefinedundefined的敏感性较低，而在λundefinedundefined>0.7时对λundefinedundefined的敏感性显著增加。
