 note = {application/pdf, In order to develop Prestressed Reinforced Concrete (PRC) beams with high impact resistant capacity for the use of rock-shed members, static loading and falling-weight impact test are conducted using prototype PRC beams. Here, total six types of PRC beams are tested which are taking shear-bending capacity ratio, pretension ratio of PC tendons, and material property and volume of rebars arranged for letting cracks disperse as variables. Impact test is conducted using 3,000 kg steel weight and applying single loading method with maximum 30 m high dropping. The results obtained from this study are as follows: 1) ductility of the beams can be improved by increasing shear-bending capacity ratio; 2) impact-resistant capacity can be increased arranging normal rebars in two levels; and 3) using high-strength PC steel rebars instead of normal rebars, not only impact resistant capacity can be most effectively increased but cracks can be dispersed over entire beam.},
