Suspension bridges due to their long span can experience large displacement response under dynamic loading like earthquakes. Unlike other structures, their vertical vibration may make remarkable difficulty that a control strategy seems to be essential. Tuned mass damper is a passive control system that can be changed to active one by adding an external source producing the active control force called active tuned mass damper. Unlike passive systems, active ones need a controller system affecting the performance of them considerably. In this study, the efficiency of tuned mass damper and active tuned mass damper are investigated in the bridges. Two controllers, fuzzy type 2 and fuzzy type 1, are used to estimate control force of active tuned mass damper. Tuned mass damper’s parameters are optimized under wide range of ground motions. Also, fuzzy type 2 and fuzzy type 1’s parameters are optimized under the influence of three different conditions containing far-field and near-field ground motions and also combination of them. In addition, Lion Pride Optimization Algorithm is selected for optimizing section. Numerical analysis indicates that active tuned mass damper is more effective than tuned mass damper, and also active tuned mass damper does not make any instability matter of concern in active control systems. Furthermore, performance of fuzzy type 2 is better than fuzzy type 1.

垂直地面运动对悬索桥的振动控制

悬索桥由于其跨度大，在地震等动力荷载作用下会产生较大的位移响应。与其他结构不同，它们的垂直振动可能会造成显着的困难，因此控制策略似乎是必不可少的。调谐质量阻尼器是一种被动控制系统，可以通过添加产生主动控制力的外部源来更改为主动控制系统，称为主动调谐质量阻尼器。与被动系统不同，主动系统需要一个控制器系统，这会显着影响它们的性能。在这项研究中，调谐质量阻尼器和主动调谐质量阻尼器的效率在桥梁中进行了研究。两个控制器，模糊类型 2 和模糊类型 1，用于估计主动调谐质量阻尼器的控制力。调谐质量阻尼器的参数在大范围的地面运动下进行了优化。还，模糊类型2和模糊类型1的参数在包括远场和近场地震动以及它们组合的三种不同条件的影响下进行优化。此外，优化部分选择了Lion Pride Optimization Algorithm。数值分析表明，主动调谐质量阻尼器比调谐质量阻尼器更有效，而且主动调谐质量阻尼器不会在主动控制系统中引起任何不稳定问题。此外，模糊类型 2 的性能优于模糊类型 1。数值分析表明，主动调谐质量阻尼器比调谐质量阻尼器更有效，而且主动调谐质量阻尼器不会在主动控制系统中引起任何不稳定问题。此外，模糊类型 2 的性能优于模糊类型 1。数值分析表明，主动调谐质量阻尼器比调谐质量阻尼器更有效，而且主动调谐质量阻尼器不会在主动控制系统中引起任何不稳定问题。此外，模糊类型 2 的性能优于模糊类型 1。
