Structural Performance of CAP-DECK
In order to verify the structural performance of CAP-DECK, we have experimented with the real size sample by using a simple 9m support, a 7m span, a both-end continuous 8.1m span, and sand. Through this experiment, we confirmed the structural integrity of CAP-DECK and verified the theory. The outstanding structural performance result indicated that the CAP-DECK only allowed about 4.6mm deflection when we installed an 8.1m shoring-free deck, considering CAP-DECK’s camber L/250 (32.4mm)
