A simplified full-depth precast concrete deck\npanel system for accelerating bridge construction (ABC) is\nintroduced and a finite element analysis (FEA) is conducted\nto investigate the static and dynamic responses of\nthis conceptual deck system. The FEA results are compared\nto those of the traditional full-depth precast concrete deck\npanel system. The comparison results show that the\nmechanical behavior of the new deck system is different\nfrom that of the traditional deck system. The concrete\ndecks in the new system act as two-way slabs, instead of\nthe one-way slab in the traditional system. Meanwhile, the\nconnections in both the longitudinal and transverse directions\nmay need to accommodate the negative moments.\nCompared to those in the traditional system, the longitudinal\nnominal stress at middle span increases a lot in the\nnew deck system and the effective flange width varies\nsignificantly. In addition, the dynamic results show that the\nimpact factor is influenced by the spacing of connections.\nFinally, some design concerns of the new deck system are\nproposed.
