意大利特伦托大学的研究人员开展了火灾下钢丝绳力学性能的试验研究和分析。火灾试验采用ISO 834标准温升曲线。建立有限元分析模型,对火灾下全封闭钢丝绳和西尔瓦灵顿混合式钢丝绳的热-力性能进行参数分析。试验结果与数值模拟结果吻合较好。在材料性能和荷载条件确定的情况下,提出的方法可以有效地分析火灾
Researchers at the University of Trento in Italy conducted a pilot study and analysis of the mechanical properties of wire ropes under fire. Fire test using ISO 834 standard temperature rise curve. The finite element analysis model was established to analyze the parameters of the thermal-mechanical properties of totally enclosed steel wire ropes and Silvallington hybrid steel ropes under fire. The experimental results agree well with the numerical simulation results. In the case of material properties and load conditions, the proposed method can effectively analyze the fire
