Steel deck plates have advantage over a long span bridge on steel read bridge. but, there are some problems by complicated shape and welding, and fatique damage ratio by growth of traffic velum. therefore, we carry out a F.E.M analysis about the through rib and c갠s beam connections. As a result the occurrence of the first a fault over the fatique of crack was not to grow. fatique life was confirmed govern to fatique crack initiation life.
