建立了某有支撑钢结构塔的简化建模,在有限元软件SAP2000中计算了其自振频率.根据数值模型,研究了不同连接方式对结构自振频率的影响.论文最后,研究了有支撑塔在不同频率激振力下塔顶部的位移响应.
The simplified modeling of some supported steel structure tower was established and its natural frequency was calculated in finite element software SAP2000.According to the numerical model, the influence of different connection modes on natural frequency of structure was studied.Finally, Displacement Response of Tower Towers at Different Frequencies of Excitation.
