Abstract:

In view of the demand of large logistics storage load and high clearance, ribbed composite slabis an ideal floor form. The finite element software numerical simulation is used to analyze the bearingcapacity and steel bar strain of the straight⁃through bottom stiffened rib composite plate and the stiffenedrib end retracted composite plate, and the rationality of the end retracted design is verified. The resultsshow that the load⁃displacement curves of the two models show three⁃stage development characteristics.The bottom stiffener straight⁃through design is more reasonable in mechanical performance.
