With the increase in population in the metropolises and the increasing need for high-rise buildings, the need for research and understanding of these structures is also increasing. The tube system is also one of the most suitable structural systems for high-rise buildings and towers. The purpose of this study is to obtain the natural frequency of structures and other seismic behavior parameters of structures with different types of tube systems for pyramidal structures. For this purpose, 24 models with four tubular structural systems including tubular, tubular with shear wall, tube-in-tube and categorized tube systems with three pyramidal angles of zero, 1.23- and 2.45-degrees deviation from vertical direction were considered according to the definition of tall buildings with three heights. They were analyzed with numerical method and analytic presented methods. In modeling, details such as peripheral walls and middle columns outside the structural system were also included in the modeling. The results of this study indicate that the investigated analytical method is in better agreement with structures with higher height and without pyramidal angle. Also, this analytical method has the least error value for the tubular system and the highest error value for tube-in-tube systems selected models.

随着大都市人口的增加和对高层建筑的需求不断增加，对这些结构的研究和了解的需求也在增加。管道系统也是高层建筑和塔楼最合适的结构系统之一。本研究的目的是获得金字塔结构不同类型管系结构的结构固有频率和其他地震行为参数。为此，我们考虑了 24 个具有四种管状结构系统的模型，包括管状、带剪力墙的管状、管中管和与垂直方向偏离 0、1.23 和 2.45 度的三个锥角的分类管系统。三个高度的高层建筑的定义。分别用数值方法和解析呈现方法进行了分析。在建模中，结构体系外的围墙、中柱等细节也被纳入了建模中。这项研究的结果表明，所研究的分析方法更符合高度较高且没有棱锥角的结构。此外，这种分析方法对于管式系统的误差值最小，而对于管中管系统所选模型的误差值最高。
