抄録: In this study, in order to establish an upgrading design procedure on impact resistance of PC snow-sheds, a new method is proposed which is composed of; 1) setting of Three-Layered Absorbing System (TLAS) on the roof to attenuate and to disperse the impact force generated due to falling rocks; 2) bonding of Aramid Fiber Reinforced Plastic (AFRP) sheet on the lower surface on the girder to upgrade the flexural capacity of girder; 3) spraying of Urethane resin on the lower surface of flange to protect concrete spalling. To confirm the applicability of the pro-posed method, the weight falling impact tests are conducted by using prototype T-shaped PC girders. The results obtained from this study are as follows: 1) PC girders can be rationally upgraded by bonding AFRP sheer on the lower surface;2) concrete spalling at the lower surface of flange can be effectively protected by spraying Urethane resin; and 3) applying a proposed estimation on impact force, upgrading of PC snow-sheds can be easily performed.
