Based on the elastic beam theory, a theoretical calculation model for the axial force of the in-service tie rod under transverse loading conditions and the three-dimensional finite element model of the prestressed beam are established. The axial force measurement method of the tie rod of the in-service support hanger is studied, and the influence of different length-to-diameter ratios and transverse loads on the deflection of the midpoint for the tie rod are discussed. The results show that the theoretical prediction results are in good agreement with the finite element calculation results. In terms of engineering applications, an optimal scheme for the length-diameter ratio of the fixed support section of the tie rod is given based on the transverse load tolerance and deflection tolerance value. This method can be used to quickly measure axial load of tie rod when it is not uninstalled.

基于弹性梁理论,建立了横向加载条件下在役拉杆轴力理论计算模型及预加应力梁的三维有限元模型,对在役支吊架拉杆轴力测量方法进行了研究,讨论了不同长径比和横向载荷对拉杆中点挠度的影响。研究结果表明,理论预测结果与有限元计算结果吻合较好;在工程应用方面给出了以横向载荷容差度及挠度容差值为指标的固支段拉杆长径比的优选方案。该方法可用于快速测量不卸载拉杆的轴向载荷。

基于弹性梁理论,建立了横向加载条件下在役拉杆轴力理论计算模型及预加应力梁的三维有限元模型,对在役支吊架拉杆轴力测量方法进行了研究,讨论了不同长径比和横向载荷对拉杆中点挠度的影响。研究结果表明,理论预测结果与有限元计算结果吻合较好;在工程应用方面给出了以横向载荷容差度及挠度容差值为指标的固支段拉杆长径比的优选方案。该方法可用于快速测量不卸载拉杆的轴向载荷。

Based on the elastic beam theory, a theoretical calculation model for the axial force of the in-service tie rod under transverse loading conditions and the three-dimensional finite element model of the prestressed beam are established. The axial force measurement method of the tie rod of the in-service support hanger is studied, and the influence of different length-to-diameter ratios and transverse loads on the deflection of the midpoint for the tie rod are discussed. The results show that the theoretical prediction results are in good agreement with the finite element calculation results. In terms of engineering applications, an optimal scheme for the length-diameter ratio of the fixed support section of the tie rod is given based on the transverse load tolerance and deflection tolerance value. This method can be used to quickly measure axial load of tie rod when it is not uninstalled.
