In order to reduce the impact of environmental vibration on building structures and precision instruments, we need to analyze and study the propagation characteristics of various vibrations in soil and structures. In this paper, taking the vibration problem of the teaching building of Chaoyang Campus of Jilin University in Changchun, China as an engineering example, the LVIB-15 portable servo controllable vibration source is used for vibration excitation, and then the different positions of the building structure and the surrounding soil are carried out on-site by testing instruments. Acquisition and analysis of dynamic characteristics, and then analysis on the basis of actual measurement data on the spot, it is concluded that: under vertical single-point simple harmonic excitation, the vertical vibration velocity of each position in each working condition is greater than the horizontal vibration velocity. In the propagation test, the farther the vibration source is from the structure, the smaller the dynamic response of the structure is. The peak values of the vertical and horizontal vibration velocities of each measuring point decay rapidly in the lower floors, and the peak values of the vertical vibration velocities gradually decay in the subsequent propagation, while the peak value of horizontal vibration velocity has a relatively slow increase in the process of propagating to high floors. From the vibration propagation test in the field, it can be known that with the increase of the distance from the vibration source, the peak values of the vertical and horizontal vibration velocities decrease continuously, the near-field attenuation is fast, and the far-field attenuation is slow. The vibration response is also related to the excitation force of the vibration source.The greater the applied force, the greater the vibration response. The vibration response of each point in winter is lower than that in summer.

Abstract-Based on detection of the Self-vibration and forced vibration the causes of resonant vibration on vibration are examined and analyzed, in order to improve the seismic capacity of coal preparation plant, the safety and normal use performance of coal preparation plant is guaranteed. The experimental result indicated that the reason make the device below the beam plate produce resonance is bending force of screening machine, the interference frequency of the screening machine is close to the first mode of the self-vibration while dynamic response increases of concrete along with the Stiffness of secondary beam and frame beam differ considerably.

“…Similar to other active control systems used in civil engineering structures, proper control strategies should be studied and shaking table tests should be conducted before full-scale applications of the EMD system can take place (Shiba et al, 1989;Soong, 1990;Yoshida et al, 1995;Spencer et al, 1998;Chu et al, 2002;Samali et al, 2003). In this paper, studies of control strategies for an innovative and special EMD control system and Bench-scale shaking table tests to validate the feasibility and effectiveness of using this type of active control system are described.…”

The electromagnetic mass damper (EMD) control system, as an innovative active control system to reduce structural vibration, offers many advantages over traditional active mass driver/damper (AMD) control systems. In this paper, studies of several EMD control strategies and bench-scale shaking table tests of a two-story model structure are described. First, two structural models corresponding to uncontrolled and Zeroed cases are developed, and parameters of these models are validated through sinusoidal sweep tests to provide a basis for establishing an accurate mathematical model for further studies. Then, a simplifi ed control strategy for the EMD system based on the pole assignment control algorithm is proposed. Moreover, ideal pole locations are derived and validated through a series of shaking table tests. Finally, three benchmark earthquake ground motions and sinusoidal sweep waves are imposed onto the structure to investigate the effectiveness and feasibility of using this type of innovative active control system for structural vibration control. In addition, the robustness of the EMD system is examined. The test results show that the EMD system is an effective and robust system for the control of structural vibrations.
