“…(1) and (2), respectively, where c is the viscous damping constant. In addition, if linear hysteretic damping, which produces an energy loss per cycle that is frequency independent, is considered for the foundation, an expression 2iDk should be added for the damping term, where D is the damping ratio [16].…”

“…To predict the dynamic response of Portland cement concrete pavement (PCCP) systems subjected to moving loads, many studies have been performed by employing beams and plates on an elastic foundation as models of PCCP systems [1][2][3][4][5][6]. When those systems are analyzed with moving loads, the effect of the rotary inertia is normally assumed to be negligible.…”

“…The effect of the axial compression in the pavement is ignored when the rigid pavement systems such as JCP and CRCP are analyzed under vehicle and environmental loads; however, it must be included when the behavior of PSCP is analyzed. Beams and plates resting on an elastic foundation have widely been used as the models of rigid pavement systems (Westergaard, 1925;Huang, 1993;Kim and Roesset, 1998;Liu et al, 2000;Chon and Lee, 2007). When those models are employed for PSCP, the loads in the beam's axial or plate's in-plane direction must be included.…”

The dynamic displacement response of a simplified prestressed concrete pavement model has been investigated comprehensively when the system is subjected to two-axle moving loads of harmonic amplitude variations. The axially loaded beam resting on a Winkler-type elastic foundation was employed as a simplified prestressed pavement model. The distributed loads with a constant advance velocity and damping of a linear hysteretic nature for the foundation were considered. Formulations were developed in the transformed field domains of time and moving space, and the steady-state responses to moving harmonic loads were obtained using a Fourier transform. Analyses were performed to investigate the effects of various parameters, such as the load distance, load phase, axial compression, damping, load velocity, and load frequency, on the displacement amplitude distribution and maximum displacement. The analysis results showed that the displacement responses were much affected by the load distance and load phase between two moving loads. However, the critical (resonance) values of the axial compression and load velocity were not affected by the load distance and phase. The first critical frequency was independent of those parameters, but the second critical frequency was dependent on them.

“…Since the general behaviors of beams and plates on an elastic foundation subjected to vehicle loads are similar to those of road pavement systems, the beams and plates on an elastic foundation are often employed for the analysis and design of the pavement systems (Huang, 1993;Kim and Roesset, 1998;Kim et al, 2002;Liu and Gazis, 1999;Liu et al, 2000;Westergaard, 1925). When the beam or plate models are used, the loads in the plate's inplane or beam's axial direction are normally assumed to be ignored.…”

The dynamic displacement response of axially loaded pavement models was investigated comprehensively when the system was subjected to two-axle moving harmonic loads whose frequencies were higher than the natural frequency of the system. The axially loaded beam on an elastic foundation was employed as a simplified pavement model under axial compression. The foundation was assumed to have damping of a linear hysteretic nature. Formulations were developed in the transformed field domains of time and moving space, and the steady-state responses to moving harmonic loads were obtained using a Fourier transform. The effects of various parameters, such as the load distance, load phase, axial compression, foundation damping, load velocity, and load frequency, on the displacement amplitude distribution and maximum displacement were investigated. The analysis results showed that the displacement responses were much affected by the load distance and load phase between two moving loads. For relatively low load velocities, the critical axial compression was dependent on the load distance and load phase, but for relatively high load velocities, it was not affected by them. There were two critical values of the load velocities and load frequencies. The second critical velocity and the first critical frequency were independent of the load distance and load phase; however, the first critical velocity and the second critical frequency were affected by them.
