Special Issue Information

Dear Colleagues,

The vibration of buildings and bridges caused by running trains, earthquakes and crosswinds greatly affects their structural performance, and this topic has been widely focused on actual engineering. For this problem, vibration control methods are widely employed in building and bridge engineering. This Special Issue focuses on building and bridge vibrations caused by running trains, earthquakes, crosswinds, etc. The potential topics for papers submitted for publication in this Special Issue include, but are not limited to, the following:

  • The modeling of building and bridge vibrations;
  • The analysis of building and bridge dynamic behaviors;
  • Experimental studies of building and bridge vibrations caused by running trains, earthquakes and crosswinds;
  • The vibration control of building and bridge

The stability of the damping pad floating slab track (DPFST) plays a critical role in the operational safety and passenger comfort of urban rail transit systems and represents a significant technical challenge. This paper introduces a novel harmonic frequency damping device (HFDD) with preload characteristics to enhance DPFST stability. First, the rubber damping pad’s constitutive relationship is determined using uniaxial tensile tests and the Mooney–Rivlin model. Next, a vehicle–track coupled dynamic model and a finite element model of the DPFST with HFDD are developed. Finally, the effects of HFDD installation and parameter adjustments on the DPFS’s modal and dynamic responses are examined. Results show that the HFDD effectively adjusts the DPFS’s natural frequency and suppresses its acceleration and displacement. Increasing HFDD stiffness from 0 to 10 kN/mm raises the DPFS’s natural frequency by up to 7.58 Hz. Within the stiffness and damping ranges of 0–20 kN/mm and 0–100 kN·s/m, respectively, the HFDD significantly reduces DPFS vibration, with maximum reductions in acceleration of 45.64% and 64.24% and in displacement of 47.55% and 39.06%. However, beyond these ranges, further increases in stiffness and damping substantially reduce the HFDD’s vibration suppression effectiveness and excessively high values are impractical for engineering use.
