Experimental research on arch transfer floor subjected to vertical loading

On the basis of theoretical analysis,properties of arch transfer floor subjected to vertical loading have been experimentally researched.The result indicates that the arch transfer floor can satisfy the requirement of large span effectively,possess relatively good ductility and avoid brittle destruction.Moreover,not only may the prestressing force in bottom chord heighten the capability of crack resistance of this chord,but also may offset the horizontal thrust of diagonal web member to substructure of the transfer floor,and improve on the mechanics performance of the transfer floor.
