abstract="Bridges are one of the most important elements of any country's surface transportation system. Closing a bridge always causes inconvenience to the public. Thus, a critical need exists for a &quot;bypass&quot; bridge that can be assembled quickly, economically, and easily at the original site or close to the bridge that is being repaired or replaced. Analytical studies indicated that integrated shell-deck segments can be used to construct short or medium-span emergency bridges. A simply supported bridge with four different shell cross sections was investigated; dead load and various patterns of live loads were considered. The analysis of these shells was performed using the ANSYS general purpose finite-element program. The results of this investigation demonstrated that shell structures can be utilized for emergency bridges.
