Abstract

The growing problems of excessive vibration in steel structures due to human rhythmic activities and vibrating machinery have led to the need for increasingly rigorous dynamic analysis in order to verify excessive displacements and ensure the users’ comfort. The present work aimed to carry out, via numerical simulation in ANSYS Mechanical APDL software, static, modal and harmonic analysis in steel frames with two floors and two bays in order to investigate the influence of the connection’s stiffness on the behavior of the structure. The results obtained showed that the natural frequency value of the models increases as the stiffness of the beam-column connections is increased. However, due to the harmonic analysis performed, it was not possible to delineate a behavior between the stiffness of the connections and the amplification.

连接刚度对钢框架静动力性能的影响

由于人类有节奏的活动和振动机械引起的钢结构过度振动问题日益严重，因此需要越来越严格的动力分析，以验证过度位移并确保用户的舒适性。本工作旨在通过ANSYS机械APDL软件的数值模拟，对两层两隔板钢框架进行静力、模态和谐波分析，以研究连接刚度对结构性能的影响。计算结果表明，随着梁柱连接刚度的增大，模型的固有频率值增大。然而，由于进行了谐波分析，不可能描述连接刚度和放大之间的行为。
