Embodiments for aircraft (100) pressure deck (150, 200). One embodiment is a pressure deck (150, 200) of an aircraft (100). The pressure deck (150, 200) includes beams (201, 202, 203) extending longitudinally along a fuselage (102) of the aircraft (100), and a web (220) attached to an underside of the beams (201, 202, 203), the web (220) including arches (222) between adjacent beams (201) to allow the pressure deck (150, 200) to flex laterally. The pressure deck (150, 200) also includes a box structure (230) between a middle pair of the beams (201, 202, 203) and configured to transfer load forward to a rear spar (126) of a wing of the aircraft (100) and aft to an aft wheel well bulkhead (128) of the aircraft (100). The pressure deck (150, 200) further includes a first intercostal (250) outboard from the box structure (230) and configured to stabilize a first outboard pair of the beams (201, 202, 203), and a second intercostal (260) outboard from the first intercostal (250) and coupled between a second outboard pair of the beams (201, 202, 203) via a swing link (362) to allow the second intercostal (260) to flex laterally.
