Lyapunov-Type Inequalities for Systems of Riemann-Liouville Fractional Differential Equations with Multi-Point Coupled Boundary Conditions

Fractal and Fractional, 2023
We consider a system of Riemann–Liouville fractional differential equations with multi-point coupled boundary conditions. Using some techniques from matrix analysis and the properties of the integral operator defined on two Banach spaces, we establish ...

不同时频特性近断层地震作用下的结构响应研究

Dizhen xuebao, 2022
研究不同时频特性的地震波作用下，抗震结构和隔震结构耦合设备的动力响应，对五层钢框架振动台模型试验数据进行小波分析。结果表明：主结构动力响应与地震波时频特性直接相关；由于主结构和隔震支座的滤波作用，设备的动力响应受地震波时频特性影响显著，但不具有直接相关性；隔震结构可以使设备的频率远离主结构的频率，从而降低设备的放大系数；设备耦合之后主体结构加速度的变化趋势取决于不同时频特性的地震波能量分布。
