Transmission towers are kinds of complex lattice structures which affects their accurate modeling and analysis and brings about some problems in the prediction of their actual behavior. For this reason, full-scale experiments are usually applied for transmission towers to examine their resistance and control their behavior. In this paper, the displacements of a transmission tower in the full-scale test, including effective parameters such as geometric and material nonlinearity and joint slip effect are attained applying the developed nonlinear analysis software. These displacements for four cases of analysis: linear, geometric nonlinear, geometric and material nonlinear and lastly, geometric and material nonlinear along with joint slip effect are obtained and compared with the results of the full-scale test. In this comparison, the results of geometric and material nonlinear analysis along with joint slip effect coincide well with the results of the full-scale experiment which demonstrates the joint slip effect importance and the capability of developed software. Finally, the tower natural frequencies are obtained and it is obvious that taking the joint slip effect into account of the analysis reduces the natural frequencies of the tower as a significant parameter in the dynamic analysis of these kind of structures either individually or as coupled system along with conductors.

输电塔是一种复杂的格子结构，会影响其精确的建模和分析，并在预测其实际行为方面带来一些问题。因此，通常对输电塔进行全面试验，以检查其阻力并控制其行为。本文使用开发的非线性分析软件，获得了输电塔在满量程试验中的位移，包括有效参数，如几何和材料非线性以及接头滑移效应。这些位移用于四种情况的分析：线性，几何非线性，几何和材料非线性，最后，几何和材料非线性以及关节滑移效应，并与全尺寸试验的结果进行比较。在这个比较中 几何和材料非线性分析的结果以及关节滑移效应与全面实验的结果吻合得很好，这表明了关节滑移效应的重要性和所开发软件的功能。最后，获得了塔架的固有频率，很明显，在分析中考虑了联合滑移效应，降低了塔架的固有频率，将其作为此类结构的动力分析的重要参数，无论是单独还是作为耦合系统沿与导体。
