摘要： 基于有限元软件ANSYS，建立了双柱悬索拉线塔的壳单元精细化有限元模型和常规梁单元模型，在试验工况下模拟拉线塔主、斜材杆件应变随荷载加载等级的变化，并将两种模型的模拟结果与试验结果对比，同时也比较了两种有限元模型对结构整体响应的影响.结果表明：壳单元模型对拉线塔主、斜材应变的模拟结果均与试验结果吻合较好，梁单元模型对主材应变的模拟结果与试验结果吻合较好，对斜材应变的模拟结果与试验结果误差较大；上述两种有限元模型对双柱悬索拉线塔的宏观响应指标的影响较小，对杆件内力的影响较大.

Abstract: Based on the finite element software ANSYS, a beam element model and a refined shell element model of the suspension cable guyed tower was established. The variation of the strain of the members with the loading level are calculated by the above-mentioned two finite element models, and the calculation results of the two models are compared with the full-scale test results. At the same time, the influence of the above-mentioned two models on the overall response of the structure are also compared. The results show that the calculation results of the refined shell element model on the strain of the main and oblique members are in good agreement with the full-scale test results. The calculation results of the beam element model on the strain of the main members also agree well with the full-scale test results. However, there is a relatively large calculation error of oblique members’ strain in beam element model. The above-mentioned two finite element models have little effect on the overall response of the suspension cable guyed tower, but the effect on internal force of the members is relatively large.
Key words: shell element model; beam element model; full-scale test; suspension cable guyed tower
