1. A cargo floor structure for a wing center section of an aircraft, the cargo floor structure comprising:
over wing floor beams extending longitudinally between a rear spar and a front spar of the aircraft, the over wing floor beams coupled with an upper skin panel of the wing center section;
intercostals extending spanwise across the over wing floor beams, the intercostals suspended over the upper skin panel; and
a truss box structure disposed between a middle pair of the over wing floor beams and configured to shear a spanwise load from the intercostals into the upper skin panel;
wherein a first intercostal and a second intercostal of the intercostals are coupled via a sliding pin configured to slide through a passageway of one of the over wing floor beams to prevent transmission of the spanwise load into the one of the over wing floor beams.
