A new dynamic finite-element computer program, DYNA-SLAB, for
the analysis of jointed concrete pavements subjected to moving transient
loads is presented. The dynamic solution is formulated in both
the time and the frequency domains. The structural model for the slab
system is the one used in the static computer program ILLI-SLAB.
’I1le foundation support is represented by either a damped Winkler
model with uniformly distributed frequency-dependent springs and
dashpots or a system of semi-infinite horizontal layers resting on a
15~gid base or a semi-infinite half-space. An important contribution
from the study is a new analytical method for determining the stiffness
and damping coefficients to be used in the Winlder foundation model.
’I]~e accuracy of DYNA-SLAB has been verified by comparing the
results produc~.~d by the program with those from theoretical closedfiarm
solutions and from a powerful dynamic soil-structure interaction
computer program called SASSI as well as with field data. The analytical
results indicate that dynamic analysis is generally not needed
f0r the design of rigid pavements and that it usually leads to decreased
p-’~vement response. Thus, it appears that a quasistatic analysis is sufficient
and that the results from this type of analysis will generally be
conservative, provided that the wheel loads used in the analysis have
been adjusted for the effects of vehicle velocity, truck suspension
characteristics., and pavement roughness
