The present study is an attempt to investigate structures equipped with friction dampers under the influence of near-field earthquakes based on Stribeck friction behavior of velocity function. At present, the cyclic behavior of friction dampers in structural design engineering software is simple and based on the Coulomb friction force that is independent of velocity, which should be estimated and considered in terms of Stribeck velocity-dependent friction. Their sliding and vibration methods, including displacement, velocity, and acceleration, are calculated using numerical analysis and differential equation. For this purpose, the representative of the near-field records affects the structure with Stribeck frictional behavior of velocity function as a pulse of Ricker wavelet stimulation. The response of the structure is evaluated in the transition phase from impending motion with a friction coefficient of μ_s to kinetic motion with μ_k and vice versa, which makes the poor results of previous simplifications more accurate. Due to the nonlinear behavior of the damping force, programming has been used to perform nonlinear analytical dynamics. Also, behavioral models in OpenSees software are used to investigate the behavior of Stribeck friction for friction damper and to compare its results with the results obtained from accurate analysis.

本研究试图基于速度函数的 Stribeck 摩擦行为研究在近场地震影响下配备摩擦阻尼器的结构。目前，结构设计工程软件中摩擦阻尼器的循环行为很简单，并且基于与速度无关的库仑摩擦力，应该根据 Stribeck 速度相关摩擦来估计和考虑。它们的滑动和振动方法，包括位移、速度和加速度，是使用数值分析和微分方程计算的。为此，近场记录的代表影响具有速度函数的 Stribeck 摩擦行为的结构，作为 Ricker 小波刺激的脉冲。μ _s与μ _{k 的}动力学运动，反之亦然，这使得先前简化的不良结果更加准确。由于阻尼力的非线性行为，编程已被用于执行非线性分析动力学。此外，OpenSees 软件中的行为模型用于研究摩擦阻尼器的 Stribeck 摩擦行为，并将其结果与从准确分析中获得的结果进行比较。
