as a frame structure with combined action of axial force and bending
moments.
As shown in Figures 10.34b and 10.35, the deck system comprises of
steel deck plates and floor beams. Steel plates are stiffened longitudinally
by U-shape stiffeners. The top of floor beams are cut out to allow stiffen-
ers to pass through. Thus, the deck clearance is minimized. There is no
stringer used in the deck system. The bottom lateral bracings are crossed
and placed in the lower part of the floor beam (Figure 10.35). The top
