Abstract:The Load and Resistance Factor Design (LRFD) method has evolved to become a
more reliable approach to bridge design in the past century. Nevertheless, safety is
always the number one concern in the design of bridge structures. Equally important,
and sometimes harder to account for in the design, is to make sure that the bridge can
be constructed with common practices and that the bridge functions as the public
expects. A good example of this is a new bridge that has adequate strength, but has
noticeable deflection under live loads. In this case the vehicle passengers as well as
pedestrians will feel uncomfortable when driving or walking over the structure because
they believe the bridge is inadequately designed.
