This paper investigates the effect of trapezoidal and sinusoidal humps on t
he dynamic response of single-span bridges. The humps exist due to several
factors such as the braking action of heavy trucks, artificial barriers to
reduce vehicle speed, and misalignment at the bridge expansion joints. The
bridge is modeled as a single-span beam with simple or hinged-hinged suppor
ts. The authors study the effects of hump type, the hump's location on the
bridge, and characteristics of the hump that affect the bridge's deflection
and acceleration responses. The effects of the hump parameters are studied
with other parameters that affect the dynamic response of the bridge, such
as vehicle speed and tire stiffness.
