FINITE ELEMENT MODEL UPDATING AND SAFETY ASSESSMENT OF IN-SERVICE CABLE-MEMBRANE STRUCTURE BASED ON SPATIAL CONFIGURATION

  • 摘要: 索膜结构的内力分布与空间位形相互关联,受施工阶段的几何找形与服役阶段的结构损伤、性能退化等影响,在役索膜结构的实际位形与设计状态有所差异,结构的服役性态未知,工程上的安全评估难以操作且并无可靠方法借鉴。该文提出了一种基于空间位形指标的在役索膜结构有限元模型修正方法,以模型中拉索的初始预应力作为优化参数、以结构关键节点坐标的匹配作为模型修正目标函数,通过构建基于结构特征点空间位置信息的目标函数来反映有限元模型与实际结构的吻合度,设计ABAQUS与MATLAB联合仿真优化程序,利用全局搜索和局部优化实现模型修正。现场试验采用三维激光扫描获取在役索膜结构空间位形信息,基于实测数据对有限元模型进行修正。修正后模型与实际结构受力状况更为接近,与索力的实测结果对比表明,有限元模型的索力由修正前最大偏差10%~30%降低至10%以下,验证了方法的有效性与准确度。利用修正后的有限元模型实现了在役索膜结构的安全评估。
