Design and modeling of towering tower structures considering horizontal vibration
Abstract
This document describes in detail the design and modeling scheme of the towering tower structure in the seventh national college students' structural design competition in Hebei Province. For the towering tower structure with horizontal vibration, this paper firstly interprets the competition problem and clarifies the design requirements and loading conditions, including three levels of loading: horizontally excited vibration, hydrostatic calm load and horizontally excited vibration of higher frequency and amplitude. Subsequently, the final model scheme was optimized and determined through material performance testing, component design and testing, structural modeling and analysis. In terms of materials, bamboo veneer and bamboo strips were used as the main materials in this paper, and their mechanical properties were tested in detail. The structure was modeled and analyzed by Midas finite element software, and the strength, stiffness and stability of the structure were comprehensively evaluated. During the modeling process, the focus was placed on the connection method of nodes, material treatment and detail construction to ensure that the model can safely carry and meet the design requirements during actual loading. After several rounds of design optimization and loading tests, the model of the towering tower structure in the form of truss structure is finally determined, and the model shows good force performance and load carrying capacity at all levels of loading conditions. The whole process of model design, fabrication and testing is recorded in detail in this paper, which provides valuable experience for the design of similar structures.
