RESPONSE OF CABLE-STAYED BRIDGES TO MOVING LOADS

In this exploratory and preliminary investigation the dynamic response of cable-stayed bridges to moving vehicular loads is studied. Effects of partial loading, vehicle speed, bridge damping and geometric nonlinearity of the structure are considered. Two bridge models having spans of 1100 ft and 2200 ft are studied; this range of spans covers both present and future designs. More comprehensive analyses are currently under investigation to shed some light on the salient features of dynamic, fatigue, live-load impact and design of these long contemporary bridges.
