The design concept of a new steel free deck is established in 4th year based on present research. The shear connecting performance of improved section with shear connecting member is experimently evaluated. The methods of crack control and shrinkage prevention is presented. The possibility of preventing brittle failure and arching action are evaluated through experiments on beam member. The wheel load fatigue test on 3 different specimens is carried out.
