摘要:
针对目前索梁锚固区数值仿真分析节段长度选取的分歧,根据某在建斜拉-自锚式悬索组合体系桥吊杆锚固区的结构特点,采用2类锚固构造和4种锚固区节段长度,建立8个壳单元模型.对不同模型中的应力、变位和结构整体屈曲特性进行对比分析.分析结果表明:采用相同锚固结构形式时,不同锚固区节段长度对锚固区应力分布情况影响较大；随着节段长度的增加,锚固区整体变位的变化趋于稳定；节段长度的选取对锚固区结构屈曲特性影响显著.不论采用何种锚固构造设置,当锚固区节段长度选取远离锚固区2倍梁高时,能较准确反应结构的受力情况.所得结论可供锚固区数值模拟及模型试验节段选取时参考.
Abstract:
According to the deficiency of numerical simulation analysis on segment selection in existing suspender anchorage zone and the characteristie of suspender anchorage zone structure in existing cable-stayedand self-anchored suspension combination bridge, 8 shell element models analysis of two anchorage zone struc-tures about four diffident anchor segment length were established. Stress distribution, displacement and buck.ling behavior of anchorage zone on the 8 models were compared. The comparison shows that, when the sameanchorage structure form is adopted, the influences of anchor segment length on the stress distribution of an.chorage zone are large ; the variation of overall dellection in the anchorage zone tends to be stable with the segment length increase; the segment length section have significant elfect on buckling behavior of anchor strucNo matter what kind of anchor construction set is adopted, the selection length of anchor segment is attire.least 2 times height of girder away from anchorage zone in order to reflect mechanical characteristics of anchorstructure. The results can be used as a reference for numerical simulation and model tests of anchor structure.
